Questions And Answers 2023 (A+)
The nurse obtains a health history from a patient with a prosthetic mitral valve who has symptoms of infective endocarditis. Which question by the nurse is most appropriate? a. "Do you have a history of a heart attack?" b. "Have you any recent immunizations?" c. "Have you been to the dentist lately?" d. "Is there a family history of endocarditis?" - Answer-C Rationale: Dental procedures place the patient with a prosthetic mitral valve at risk for infectious endocarditis (IE). Myocardial infarction (MI), immunizations, and a family history of endocarditis are not risk factors for IE. The health care provider writes the following admitting orders for a patient with suspected IE who has fever and chills: ceftriaxone (Rocephin) 1.0 g intravenous piggyback (IVPB) q12hr, acetylsalicylic acid (ASA) for temperature above 102° F (38.9° C), and blood cultures 2, complete blood cell count (CBC), and electrocardiogram (ECG). When admitting the patient, the nurse gives the highest priority to a. obtaining the blood cultures. b. initiating the IV antibiotic. c. scheduling the ECG. d. administering the ASA. - Answer-A Rationale: Treatment of the IE with antibiotics should be started as quickly as possible, but it is essential to obtain blood cultures before initiating antibiotic therapy to obtain accurate sensitivity results. The ECG and ASA should also be accomplished rapidly, but the blood cultures (and then administration of the antibiotic) have highest priority. During the assessment of a patient with IE, the nurse would expect to find a. substernal chest pain and pressure. b. splinter hemorrhages of the lips. c. dyspnea and a dry, hacking cough. d. a new regurgitant murmur. - Answer-D Rationale: New regurgitant murmurs occur in IE because vegetation on the valves prevents valve closure. Splinter hemorrhages occur on the nailbeds. Chest pain for pressure is not typical for the patient with IE and would be more consistent with angina or MI. Although dyspnea may occur as a result of heart failure, a moist cough would be expected rather than a dry, hacking cough. A patient hospitalized with IE develops sharp left flank pain and hematuria. The nurse notifies the health care provider, recognizing that these symptoms may indicate a. septicemia. b. acute pyelonephritis. c. vegetative embolization. d. glomerulonephritis. - Answer-C
Rationale: The patient's clinical manifestations and history of IE indicate embolization. Sudden onset flank pain is not typical of pyelonephritis, septicemia, or glomerulonephritis. Which of these assessment data obtained by the nurse when assessing a patient with acute pericarditis should be reported immediately to the health care provider? a. Blood pressure (BP) of 166/ b. Jugular vein distension (JVD) to the level of the jaw c. Pulsus paradoxus 8 mm Hg d. Level 6/10 chest pain with deep inspiration - Answer-B Rationale: The JVD indicates that the patient may have developed cardiac tamponade and may need rapid intervention to maintain adequate cardiac output. Hypertension would not be associated with complications of pericarditis, and the BP is not high enough to indicate that there is any immediate need to call the health care provider. A pulsus paradoxus of 8 mm Hg is normal. Level 6/10 chest pain should be treated but is not unusual with pericarditis. The nurse has identified a nursing diagnosis of acute pain related to inflammatory process for a patient with acute pericarditis. The most appropriate intervention by the nurse for this problem is to a. force fluids to 3000 ml/day to decrease fever and inflammation. b. teach the patient to take deep, slow respirations to control the pain. c. position the patient in Fowler's position, leaning forward on the overbed table. d. remind the patient to ask for the opioid pain medication every four hours. - Answer-C Rationale: Sitting upright and leaning forward frequently will decrease the pain associated with pericarditis. Forcing fluids will not decrease the inflammation or pain. Taking deep respirations tends to increase pericardial pain. Opioids are not very effective at controlling pain caused by acute inflammatory conditions and are usually ordered PRN. The patient would receive scheduled doses of a nonsteroidal antiinflammatory drug (NSAID). During postoperative teaching with a patient who had a mitral valve replacement with a mechanical valve, the nurse instructs the patient regarding a. the need to avoid high-voltage electrical fields. b. how to monitor anticoagulation therapy. c. the need for valve replacement in 7 to 10 years. d. how to check the radial pulse. - Answer-B Rationale: Anticoagulation with warfarin (Coumadin) is needed for a patient with mechanical valves to prevent clotting on the valve. There is no need to avoid high- voltage electrical fields. Mechanical valves are durable and would last longer than 7 to 10 years. Monitoring of radial pulse is not necessary after valve replacement. Which information obtained by the nurse when assessing a patient admitted with mitral valve stenosis should be communicated to the health care provider immediately? a. The patient has a loud diastolic murmur all across the precordium. b. The patient has crackles audible to the lung apices.
a. edematous compression of the cord above the level of the injury b. continued trauma to the cord resulting from damage to stabilizing ligaments c. infarction and necrosis of the cord caused by edema, hemorrhage, and metabolites d. mechanical transection of the cord by sharp vertebral bone fragments after the initial injury - Answer-c. infarction and necrosis of the cord caused by edema, hemorrhage, and metabolites Rationale: The primary injury of the spinal cord rarely affects the entire cord, but the patho of secondary injury may result in damage that is the same as mechanical severance of the cord. Complete cord dissolution occurs through autodestruction of the cord by hemorrhage, edema, and the presence of metabolites and norepinephrine. resulting in anoxia and infarction of the cord. Edema resulting from the inflammatory response may increase the damage as it extends above and below the injury site. A patient with a spinal cord injury has spinal shock. The nurse plans care for the patient based on the knowledge that a. rehabilitation measures cannot be initiated until spinal shock has resolved b. the patient will need continuous monitoring for hypotension, tachycardia, and hypoxemia c. resolution of spinal shock is manifested by spasticity, hyperreflexia, and reflex emptying of the bladder d. the patient will have complete loss of motor and sensory functions below the level of the injury, but autonomic functions are not affected - Answer-C. c. resolution of spinal shock is manifested by spasticity, hyperreflexia, and reflex emptying of the bladder Rationale: Spinal shock occurs in about half of all people with acute spinal cord injury. In spinal shock, the entire cord below the level of the lesion fails to function, resulting in a flaccid paralysis and hypomotility of most processes without any reflex activity. Return of reflex activity signals the end of spinal shock. Sympathetic function is impaired below the level of the injury because sympathetic nerves leave the spinal cord at the thoracic and lumbar areas, and cranial parasympathetic nerves predominate in control over respirations, heart, and all vessels and organ below the injury. Neurogenic shock results from loss of vascular tone caused by the injury and is manifested by hypotension, peripheral vasodilation, and decreased CO. Rehab activities are not contraindicated during spinal shock and should be instituted if the patient's cardiopulmonary status is stable. Two days following a spinal cord injury, a patient asks continually about the extent of impairment that will result from the injury. The best response by the nurse is, a. you will have more normal function when spinal shock resolves and the reflex arc returns b. the extent of your injury cannot be determined until the secondary injury to the cord is resolved c. when your condition is more stable, an MRI will be done that can reveal the extent of the cord damage d. because long-term rehabilitation can affect the return of tunction, it will be years before we can tell when the complete effect will be
B. the extent of your injury cannot be determined until the secondary injury to the cord is resolved - Answer-Rationale: Until the edema and necrosis at the site of the injury are resolved in 72 hours to 1 week after the injury, it is not possible to determine how much cord damage is present from the initial injury, how much secondary injury occurred, or how much the cord was damaged by edema that extended above the level of the original injury. The return of reflexes signals only the end of spinal shock, and the reflexes may be inappropriate and excessive, causing spasms that complicate rehab. A patient is admitted to the emergency department with a spinal cord injury at the level of T2. Which of the following findings is of most concern to the nurse? a. SpO2 of 92% b. HR of 42 beats/min c. BP of 88/ d. loss of motor and sensory function in arms and legs - Answer-b. HR of 42 beats/min Rationale: Neurogenic shock associated with cord injuries above the level of T6 greatly decrease the effect of the sympathetic nervous system, and bradycardia and hypotension occur. A heart rate of 42 is not adequate to meet oxygen needs of the body, and while low, the BP is not at a critical point. The O2 sat is ok, and the motor and sensory loss are expected. A patient is admitted to the emergency department with a possible cervical spinal cord injury following an automobile crash. During the admission of the patient, the nurse places the highest priority on a. maintaining a patent airway b. assessing the patient for head and other injuries c. maintaining immobilization of the cervical spine d. assessing the patient's motor and sensory function - Answer-a. maintaining a patent airway Rationale: The need for a patent airway is the first priority for any injured patient, and a high cervical injury may decrease the gag reflex and ability to maintain an airway, as well as the ability to breathe. Maintaining cervical stability is then a consideration, along with assessing for other injuries and the patients neuro status. Without surgical stabilization, immobilization and traction of the patient with a cervical spinal cord injury most frequently requires the use of a. kinetic beds b. hard cervical collars c. skeletal traction with skull tongs d. sternal-occipital-mandibular immobilizer (SOMI) brace - Answer-C. skeletal traction with skull tongs Rationale: Cervical injuries usually require skeletal traction with the use of Crutchfield, Vinke, or other types of skull tongs to immobilize the cervical vertebrae, even if fracture has not occurred. Hard cervical collars are used for minor injuries or for stabilization during emergency transport of the patient. Sandbags are also used temporarily to stabilize the neck during insertion of tongs or during diagnostic testing immediately
A nurse is planning care for a client who suffered a spinal cord injury (SCI) involving a T12 fracture 1 week ago. The client has no muscle control of the lower limbs, bowel, or bladder. which of the following should be the nurses' greatest priority? a. prevention of further damage to the spinal cord b. prevention of contractures of the lower extremities c. prevention of skin breakdown of areas that lack sensation d. prevention of postural hypotension when placing the client in a wheelchair - Answer- A. prevention of further damage to the spinal cord Rationale: The greatest risk to the client during the acute phase of a SCI is further damage to the spinal cord. Therefore, when planning care, the priority should be the prevention of further damage to the spinal cord by administration of corticosteroids, minimizing movement of the client until spinal stabilization is accomplished through either traction or surgery, and adequate oxygenation of the client to decrease ischemia of the spinal cord. A nurse is caring for a client who has a C4 spinal cord injury. which of the following should the nurse recognize the client as being at the greatest risk for? a. neurogenic shock b. paralytic ileus c. stress ulcer d. respiratory compromise ventilator support as needed is the priority intervention. - Answer-D. respiratory compromise Rationale: Using the airway, breathing and circulation priority framework, the greatest risk to the client with a SCI at the level of C4 is respiratory compromise secondary to involvement of the phrenic nerve. Maintainance of an airway and provision of A patient is admitted to the hospital with a CD4 spinal cord injury after a motorcycle collision. The patient's BP is 83/49, and his pulse is 39 beats/min, and he remains orally intubated. The nurse identifies this pathophysiologic response as caused by a. increased vasomotor tone after injury b. a temporary loss of sensation and flaccid paralysis below the level of injury c. loss of parasympathetic nervous system innervation resulting in vasoconstriction d. loss of sympathetic nervous system innervation resulting in peripheral vasodilation - Answer-D. loss of sympathetic nervous system innervation resulting in peripheral vasodilation In conducting a primary survey on a trauma patient, which of the following is considered one of the priority elements of the primary survey? a.) Complete set of vital signs b.) Palpation and auscultation of the abdomen c.) Brief neurologic assessment d.) Initiation of pulse oximetry - Answer-c.) Brief neurologic assessment
Rationale: A brief neurologic assessment to determine level of consciousness and pupil reaction is part of the primary survey. Vital signs, assessment of the abdomen, and initiation of pulse oximetry are considered part of the secondary survey. A client admitted to the hospital with a subarachnoid hemorrhage has complaints of severe headache, nuchal rigidity, and projectile vomiting. The nurse knows lumbar puncture (LP) would be contraindicated in this client in which of the following circumstances? a.) Vomiting continues b.) Intracranial pressure (ICP) is increased c.) The client needs mechanical ventilation d.) Blood is anticipated in the cerebralspinal fluid (CSF) - Answer-b.) Intracranial pressure (ICP) is increased Rationale: Sudden removal of CSF results in pressures lower in the lumbar area than the brain and favors herniation of the brain; therefore, LP is contraindicated with increased ICP. Vomiting may be caused by reasons other than increased ICP; therefore, LP isn't strictly contraindicated. An LP may be preformed on clients needing mechanical ventilation. Blood in the CSF is diagnostic for subarachnoid hemorrhage and was obtained before signs and symptoms of ICP. Which of the following signs and symptoms of increased ICP after head trauma would appear first? a.) Bradycardia b.) Large amounts of very dilute urine c.) Restlessness and confusion d.) Widened pulse pressure - Answer-c.) Restlessness and confusion Rationale: The earliest symptom of elevated ICP is a change in mental status. Bradycardia, widened pulse pressure, and bradypnea occur later. The client may void large amounts of very dilute urine if there's damage to the posterior pituitary. The nurse is evaluating the status of a client who had a craniotomy 3 days ago. The nurse would suspect the client is developing meningitis as a complication of surgery if the client exhibits: a.) A positive Brudzinski's sign b.) A negative Kernig's sign c.) Absence of nuchal rigidity d.) A Glascow Coma Scale score of 15 - Answer-a.) A positive Brudzinski's sign
Rationale: Anxiety, flushing above the level of the lesion, piloerection, hypertension, and bradycardia are symptoms of autonomic dysreflexia, typically caused by such noxious stimuli such as a full bladder, fecal impaction, or decubitus ulcer. Putting the client flat will cause the blood pressure to increase even more. The indwelling urinary catheter should be assessed immediately after the HOB is raised. Nitroglycerin is given to reduce chest pain and reduce preload; it isn't used for hypertension or dysreflexia. Which of the following conditions indicates that spinal shock is resolving in a client with C7 quadriplegia? a.) Absence of pain sensation in chest b.) Spasticity c.) Spontaneous respirations d.) Urinary continence - Answer-b.) Spasticity Rationale: Spasticity, the return of reflexes, is a sign of resolving shock. Spinal or neurogenic shock is characterized by hypotension, bradycardia, dry skin, flaccid paralysis, or the absence of reflexes below the level of injury. The absence of pain sensation in the chest doesn't apply to spinal shock. Spinal shock descends from the injury, and respiratory difficulties occur at C4 and above. In promoting health maintenance for prevention of strokes, the nurse understands that the highest risk for the most common type of stroke is present in a. African Americans b. women who smoke c.individuals with hypertension and diabetes d. those who are obese with high dietary fat intake - Answer-C: Individuals with hypertension and diabetes- The highest risk factors for thrombotic stroke are hypertension and diabetes. African Americans have a higher risk for stroke than do white persons but probably because they have a greater incidence of hypertension. Factors such as obesity, diet high in saturated fats and cholesterol, cigarette smoking, and excessive alcohol use are also risk factors but carry less risk than hypertension. A patient comes to the emergency department immediately after experiencing numbness of the face and an inability to speak, but while the patient awaits examination, the symptoms disappear and the patient request discharge. The nurse stresses that it is important for the patient to be evaluated primarily because a. the patient has probably experienced an asymptomatic lacunar stroke b. the symptoms are likely to return and progress to worsening neurologic deficit in the next 24 hours c. neurologic deficits that are transient occur most often as a result of small hemorrhages that clot off d. the patient has probably experienced a transient ischemic attack (TIA), which is a sign of progressive cerebral vascular disease - Answer-D: The patient has probably
experienced a transient ischemic attack (TIA), which is a sign of progressive cerebral vascular disease- A TIA is a temporary focal loss of neurologic function caused by ischemia of an area of the brain, usually lasting only about 3 hours. TIAs may be due to microemboli from heart disease or carotid or cerebral thrombi and are a warning of progressive disease. Evaluation is necessary to determine the cause of the neurologic deficit and provide prophylactic treatment if possible. A patient is admitted to the hospital with a left hemiplegia. To determine the size and location and to ascertain whether a stroke is ischemic or hemorrhagic, the nurse anticipates that the health care provider will request a a. CT scan b. lumbar puncture c. cerebral arteriogram d. positron emission tomography (PET) - Answer-A: CT scan- A CT scan is the most commonly used diagnostic test to determine the size and location of the lesion and to differentiate a thrombotic stroke from a hemorrhagic stroke. Positron emission tomography (PET) will show the metabolic activity of the brain and provide a depiction of the extent of tissue damage after a stroke. Lumbar punctures are not performed routinely because of the chance of increased intracranial pressure causing herniation. Cerebral arteriograms are invasive and may dislodge an embolism or cause further hemorrhage; they are performed only when no other test can provide the needed information. A carotid endarterectomy is being considered as a treatment for a patient who has had several TIAs. The nurse explains to the patient that this surgery a. is used to restore blood to the brain following an obstruction of a cerebral artery b. involves intracranial surgery to join a superficial extracranial artery to an intracranial artery c. involves removing an atherosclerotic plaque in the carotid artery to prevent an impending stroke d. is sued to open a stenosis in a carotid artery with a balloon and stent to restore cerebral circulation - Answer-C: Involves removing an atherosclerotic plaque in the carotid artery to prevent an impending stroke- An endarterectomy is a removal of an atherosclerotic plaque, and plaque in the carotid artery may impair circulation enough to cause a stroke. A carotid endarterectomy is performed to prevent a cerebrovascular accident (CVA), as are most other surgical procedures. An extacranial-intracranial bypass involves cranial surgery to bypass a sclerotic intacranial artery. Percutaneous transluminal angioplasty uses a balloon to compress stenotic areas in the carotid and vertebrobasilar arteries and often includes inserting a stent to hold the artery open The incidence of ischemic stroke in patients with TIAs and other risk factors is reduced with administration of a. furosemide (Lasix) b. lovastatin (Mevacor) c. daily low dose aspirin
plantar flexion. The unaffected arm should be supported, but immobilization may precipitate a painful shoulder-hand syndrome. The patient should be positioned with each joint higher than the joint proximal to it to prevent dependent edema. A newly admitted patient who has suffered a right sided brain stroke has a nursing diagnosis of disturbed visual sensory perception related to homonymous hemianopsia. Early in the care of the patient, the nurse should a. place objects on the right side within the patient's field of vision b. approach the patient from the left side to encourage the patient to turn the head c. place objects on the patient's left side to assess the patient's ability to compensate d. patch the affected eye to encourage the patient to turn the head to scan the environment - Answer-A: Place objects on the right side within the patient's field of vision- the presence of homonymous hemianopia in a patient with right-hemisphere brain damage causes a loss of vision in the left field. Early in the care of the patient, objects should be placed on the right side of the patient in the field of vision, and the nurse should approach the patient from the right side. Later in treatment, patients should be taught to turn the head and scan the environment and should be approached from the affected side to encourage head turning. Eye patches are used if patients have diplopia (double vision). Four days following a stroke, a patient is to start oral fluids and feedings. Before feeding the patient, the nurse should first a. check the patient's gag reflex b. order a soft diet for the patient c. raise the head of the bed to sitting position d. evaluate the patient's ability to swallow small sips of ice water - Answer-A: check the patient's gag reflex- the first step in providing oral feedings for a patient with a stroke is ensuring that the patient has an intact gag reflex because oral feedings will not be provided if gag reflex is impaired. The nurse should then evaluate the patient's ability to swallow ice chips or ice water after placing the patient in an upright position A patient's wife asks the nurse why her husband did not receive the clot busting medication (tPA) she has been reading about. Her husband is diagnosed with a hemorrhagic stroke. What should the nurse respond? a. He didn't arrive within the time frame for that therapy b. Not every is eligible for this drug. Has he had surgery lately? c. You should discuss the treatment of your husband with your doctor d. The medication you are talking about dissolves clots and could cause more bleeding in your husband's head - Answer-D: The medication you are talking about dissolves clots and could cause more bleeding in your husband's head- tPA dissolves clots and increases the risk for bleeding. It is not used with hemorrhagic strokes. If the patient had a thrombotic/embolic stroke the time frame would be important as well as a history of surgery. The nurse should answer the question as accurately as possible and then encourage the individual to talk with the primary care physician if he or she has further questions.
A patient with right hemisphere stroke has a nursing diagnosis of unilateral neglect related to sensory perceptual deficits. During the patient's rehabilitation, it is important for the nurse to a. avoid positioning the patient on the affected side b. place all objects for care on the patient's unaffected side c. teach the patient to care consciously for the affected side d. protect the affected side from injury with pillows and supports C: Teach the patient to care consciously for - Answer-the affected side- unilateral neglect, or neglect syndrome, occurs when the patient with a stroke is unaware of the affected side of the body, which puts the patient at risk for injury. During the acute phase, the affected side is cared for by the nurse with positioning and support, during rehabilitation the patient is taught to care consciously for and attend to the affected side of the body to protect it from injury. Patients may be positioned on the affected side for up to 30 minutes. A patient with a stroke has a right sided hemiplegia. The nurse prepares family members to help control behavior changes seen with this type of stroke by teaching them to a. ignore undesirable behaviors manifested by the patient b. provide directions to the patient verbally in small steps c. distract the patient from inappropriate emotional responses d. supervise all activities before allowing the patient to pursue them independently - Answer-C: Distract the patient from inappropriate emotional responses- patients with left-sided brain damage from stroke often experience emotional lability, inappropriate emotional responses, mood swings, and uncontrolled tears or laughter disproportionate or out of context with the situation. The behavior is upsetting and embarrassing to both the patient and the family, and the patient should be distracted to minimize its presence. Patients with right-brain damage often have impulsive, rapid behavior that supervision and direction. The nurse can assist the patient and the family in coping with the long term effects of a stroke by a. informing family members that the patient will need assistance with almost all ADLs b. explaining that the patient's prestroke behavior will return as improvement progresses c. encouraging the patient and family members to seek assistance from family therapy or stroke support groups d. helping the patient and family understand the significance of residual stroke damage to promote problem solving and planning - Answer-D: Helping the patient and family understand the significance of residual stroke damage to promote problem solving and planning- the patient and family need accurate and complete information about the effects of the stroke to problem solve and make plans for chronic care of the patient. It is uncommon for patients with major strokes to return completely to pre stroke function, behaviors, and role, and both the patient and family will mourn these losses. The patient's specific needs for care must be identified, and rehabilitation efforts should be continued at home. Family therapy and support groups may be helpful for some patients and families.
Rationale: Internal rotation, adduction, and flexion of the arms in an unconscious patient is documented as decorticate posturing. Extension of the arms and legs is decerebrate posturing. Because the flexion is general, it does not indicate localization of pain or flexion withdrawal. A patient has ICP monitoring with an intraventricular catheter. A priority nursing intervention for the patient is a. aseptic technique to prevent infection b. constant monitoring of ICP waveforms c. removal of CSF to maintain normal ICP d. sampling CSF to determine abnormalities - Answer-A. Aseptic technique to prevent infection An intraventricular catheter is a fluid coupled system that can provide direct access for microorganisms to enter the ventricles of the brain, and aseptic technique is a very high nursing priority to decrease the risk for infection. Constant monitoring of ICP waveforms is not usually necessary, and removal of CSF for sampling or to maintain normal ICP is done only when specifically ordered A patient with ICP monitoring has pressure of 12 mm Hg. The nurse understand that this pressure reflects a. a severe decrease in cerebral perfusion pressure b. an alteration in the production of CSF c. the loss of autoregulatory control of ICP d. a normal balance between brain tissue, blood, and CSF - Answer-D. A normal balance between brain tissue, blood, and CSF- normal is 10- 15 mm Hg During admission of a patient with a severe head injury to the ED, the nurse places highest priority on assessment for a. patency of of airway b. presence of a neck injury c. neurologic status with Glascow Coma Scale d. CSF leakage from ears and nose - Answer-A. Patency of airway is the #1 priority with all head injuries When a patient is admitted to the emergency department following a head injury, the nurse's first priority in management of the patient once a patent airway is confirmed is a. maintaining cervical spine precautions b. determining the presence of increased ICP c. monitoring for changes in neurologic status d. establishing IV access with a large-bore catheter - Answer-A. In addition to monitoring for a patent airway during emergency care of the patient with a head injury, the nurse must always assume that a patient with a head injury may have a cervical spine injury. Maintaining cervical spine precautions in all assessment and treatment activities with the patient is essential to prevent additional neurologic damage.
The nurse recognizes the presence of Cushing's triad in the patient with a. Increased pulse, irregular respiration, increased BP b. decreased pulse, irregular respiration, increased pulse pressure c. increased pulse, decreased respiration, increased pulse pressure d. decreased pulse, increased respiration, decreased systolic BP - Answer-B. Cushing's triad consists of three vital sign measures that reflect ICP and its effect on the medulla, the hypothalamus, the pons, and the thalamus. Because these structures are very deep, Cushing's triad is usually a late sign of ICP. The signs include an increasing systolic BP with a widening pulse pressure, a bradycardia with a full and bounding pulse, and irregular respirations. A nurse is positioning a client with increased ICP. Which position would the nurse avoid? A. head midline B. head turned to the side C. neck in neutral position D. head of bed elevated 30-45 degrees - Answer-B. head turned to the side The head of a client with increased ICP should be positioned so that the head is in a neutral, midline position. The nurse should avoid flexing or extending the neck or turning the head side to side. The head of the bed should be raised 30-45 degrees. Use of proper position promotes venous drainage from the cranium to keep ICP down A patient with a head injury has bloody drainage from the ear. To determine whether CSF is present in the drainage, the nurse a. examines the tympanic membrane for a tear b. tests the fluid for a halo sign on a white dressing c. tests the fluid with a glucose identifying strip or stick d. collects 5 mL of fluid in a test tube and sends it to the laboratory for analysis - Answer-B. Tests the fluid for a halo sing on a white dressing- Testing clear drainage for CSF in nasal or ear drainage may be done with a Dextrostik or Tes-Tape strip, but if blood is present, the glucose in the blood will produce and unreliable result. To test bloody drainage, the nurse should test the fluid for a halo or ring that occurs when a yellowish ring encircles blood dripped onto a white pad or towel A client recovering from a head injury is arousable and participating in care. The nurse determines that the client understands measures to prevent elevations in intracranial pressure if the nurse observes the client doing which of the following activities? A. blowing the nose B. isometric exercises C. coughing vigorously D. exhaling during repositioning - Answer-D. exhaling during repositioning (activities that increase intra-throacic and intra-abdominal pressures cause indirect elevation of the ICP. Exhaling during activities such as repositioning or pulling up in bed opens the glottis, which prevents intra-thoracic pressure from rising).
C. Temperature over 100.4° F (38° C) D. Heart rate decreases from 75 to 55 beats/minute
. - Answer-D. Heart rate decreases from 75 to 55 beats/minute Cushing's triad is systolic hypertension with a widening pulse pressure, bradycardia with a full and bounding pulse, and slowed respirations. The rise in blood pressure is an attempt to maintain cerebral perfusion, and it is a neurologic emergency because decompensation is imminent. The other options are not part of Cushing's triad The patient has rhinorrhea after a head injury. What action should you take? A. Pack the nares with sterile gauze. B. A loose collection pad may be placed under the nose. C. Suction the drainage with an inline suction catheter. D. Obtain a sample for culture. - Answer-B. A loose collection pad may be placed under the nose. A loose collection pad may be placed under the nose. Do not place a dressing in the nasal cavity, and nothing should be placed inside the nostril. There is no need to culture the drainage. The concern is whether it is spinal fluid, which is determined by a test for glucose or the halo or ring sign. You plan care for the patient with increased ICP with the knowledge that the best way to position the patient is to A. keep the head of the bed flat. B. elevate the head of the bed to 30 degrees. C. maintain patient on the left side with the head supported on a pillow. D. use a continuous-rotation bed to continuously change patient position. - Answer-B. elevate the head of the bed to 30 degrees. You should maintain the patient with increased ICP in the head-up position. Elevation of the head of the bed to 30 degrees enhances respiratory exchange and aids in decreasing cerebral edema. You should position the patient to prevent extreme neck flexion, which can cause venous obstruction and contribute to elevated ICP. Elevation of the head of the bed reduces sagittal sinus pressure, promotes drainage from the head through the valveless venous system in the jugular veins, and decreases the vascular congestion that can produce cerebral edema. However, raising the head of the bed above 30 degrees may decrease the cerebral perfusion pressure (CPP) by lowering systemic blood pressure. Careful evaluation of the effects of elevation of the head of the bed on the ICP and the CPP is required. You are caring for a patient admitted with a subdural hematoma after a motor vehicle accident. Which change in vital signs would you interpret as a manifestation of increased intracranial pressure? A. Tachypnea B. Bradycardia C. Hypotension D. Narrowing pulse pressure - Answer-B. Bradycardia
Changes in vital signs indicative of increased ICP are known as Cushing's triad, which consists of increasing systolic pressure with a widening pulse pressure, bradycardia with a full and bounding pulse, and irregular respirations. When assessing a patient with newly diagnosed trigeminal neuralgia, the nurse will ask the patient about a. triggers that lead to facial pain. b. visual problems caused by ptosis. c. poor appetite caused by a loss of taste. d. decreased sensation on the affected side. - Answer-Correct Answer: A. Rationale: The major clinical manifestation of trigeminal neuralgia is severe facial pain that is triggered by cutaneous stimulation of the nerve. Ptosis, loss of taste, and numbness are not characteristics of trigeminal neuralgia, although ptosis and numbness may occur after therapy, and poor appetite may be associated with pain stimulated by eating. A 38-year-old woman has newly diagnosed multiple sclerosis (MS) and asks the nurse what is going to happen to her. What is the best response by the nurse? a. "You will have either periods of attacks and remissions or progression of nerve damage over time." b. "You need to plan for a continuous loss of movement, sensory functions, and mental capabilities." c. "You will most likely have a steady course of chronic progressive nerve damage that will change your personality." d. "It is common for people with MS to have an acute attack of weakness and then not to have any other symptoms for years." - Answer-a. "You will have either periods of attacks and remissions or progression of nerve damage over time." Most patients with multiple sclerosis (MS) have remissions and exacerbations of neurologic dysfunction or a relapsing-remitting initial course followed by progression with or without occasional relapses, minor remissions, and plateaus that progressively cause loss of motor, sensory, and cerebellar functions. Intellectual function generally remains intact but patients may experience anger, depression, or euphoria. A few people have chronic progressive deterioration and some may experience only occasional and mild symptoms for several years after onset. During assessment of a patient admitted to the hospital with an acute exacerbation of MS, what should the nurse expect to find? a. Tremors, dysphasia, and ptosis b. Bowel and bladder incontinence and loss of memory c. Motor impairment, visual disturbances, and paresthesias
