1. Which of the following requires you to develop a plan of action,
initiate the plan, reassess the plan as care for the patient moves
forward, and adjust the plan as the patient's condition or circumstances
change?
A. Principles of PHTLS
B. The Golden Period
C. The XABCDE assessment
D. Critical thinking process - ansQuestion 1: D
To help achieve the PHTLS goals, you will apply your critical thinking skills in
the field. Critical thinking in medicine is a process in which the healthcare
practitioner assesses the situation, the patient, and the resources available
and uses the information to decide on and provide the best care for the
patient.
1. You and your partner are responding to a call for a 2-year-old patient
with a burn injury to the hand. He has a visible burn to the left hand,
ending at the level above the wrist, red color, and wet in appearance.
What type of burn do you suspect the patient has sustained?
A. Superficial (first degree)
B. Partial thickness (second degree)
C. Full thickness (third degree)
D. Subdermal (fourth degree) - ansQuestion 1: B
Scald burns are the most common burns seen in the pediatric population
ages 1 to 5 years. Scalds are partial thickness burns. The dermal layer is
damaged, and blisters are present or popped. It is also the most painful type
of burn.
1. You are called to the scene of a possible mass casualty motor vehicle
collision on the highway. Once you arrive on scene, what is your first
priority?
A. Immediately begin triaging patients.
B. Treat the patient with the most visible blood loss.
C. Determine the need for additional resources.
D. Assess the scene and ensure it is safe. - ansQuestion 1: D
Ensure safety for responders, bystanders, and patient(s). The first
consideration when approaching any scene is the safety of all emergency
responders. When EMS personnel become victims, they not only can no
longer assist others, but also add to the number of patients.

air. She is taking warfarin for a clotting issue. Which of the following should you suspect? A. Cerebral contusion B. Epidural hematoma C. Subarachnoid hemorrhage D. Subdural hematoma - ansQuestion 1: D The patient's age, use of a blood thinner, and the fact she fell recently point to a subdural hematoma.

  1. Your partner is compressing the bleeding site of a male patient who was stabbed multiple times in the left chest. The bleeding seems to be controlled, yet the patient becomes combative. He is pale and is breathing rapidly, yet states that he "can't breathe" and feels that he is about to die. Your next step in patient management is to: A. start assisted ventilation. B. give high-flow oxygen. C. decompress the left chest. D. give a 250-mL fluid bolus. - ansQuestion 1: C After X come A and B. You can quickly auscultate the lungs (pneumothorax is almost certain with multiple stabs in the chest) and decompress the chest. Decompressing a tension pneumothorax is the quickest way to treat shock.
  2. Your patient is experiencing severe pain after sustaining a femur fracture in a motorcycle crash. You have a 20 minute transport to the nearest trauma center. There are no other injuries noted on your primary and secondary assessments. Which of the following medications would be the best pain management choice? A. NSAIDs B. Acetaminophen C. Fentanyl D. Morphine - ansQuestion 1: C Fentanyl is often a first-line agent due to speed of onset, short duration of action, and minimal effect on hemodynamics. Fentanyl can beadministered IN, IM, IO, or IV. The IV route provides effects instantly whereasthe IN and IM route have an onset of <10 minutes. The duration of fentanyl is short at 30 minutes to an hour. This will provide enough time to ease pain during transport and let the traumacenter decide pain management upon arrival.
  3. A trauma patient from the highway incident is holding her right arm, and you note a significant amount of blood steadily flowing from a long gash. This is an example of what type of hemorrhage? A. Capillary bleeding B. Venous bleeding C. Arterial bleeding D. Road rash - ansQuestion 2: B Venous bleeding typically results in a steady flow of dark red blood.

Edition ENA Test Bank |Graded A+ pass

  1. During primary survey, you find the following: . LOC: alert and oriented; speaking in full sentences . GCS: 15 . Airway: good air entry to bases . Breathing: bilateral . Circulation: skin warm, flushed, dry . Pulse rate: 112 bpm, strong andregular . BP: 90/42 mm Hg . Pain: Patient complains of severe pain at clavicle site and pain on inspiration at site of possible fractured ribs. No other injuries detected. What is your next step? A. Apply a cervical collar and in-line immobilization device. B. Treat for hypovolemic shock. C. Apply an arm sling for the clavicle injury. D. Administer pain medication. - ansQuestion 2: A Although the patient's GCS is normal, she does have a distracting injury, and the state of her helmet indicates possible spinal compression/flexion, so you should immobilize the patient.
  2. The patient becomes apneic. You suspect he has a cervical injury. Which type of airway should you use? A. Supraglottic airway B. Blind nasotracheal intubation C. Oropharyngeal airway D. Surgical airway - ansQuestion 2: A The supraglottic airway's greatest advantage is that it can be inserted independent of the patient's position, which may be especially important in trauma patients with high suspicion of cervical injury.
  3. The patient's care giver is a babysitter who reports the child was crawling on the counter and placed his hand in a pot of water that was boiling on the stove. She is applying ice to the burn and the child is shivering. What is your next step? A. Administer analgesia for pain. B. Cover the patient with a blanket to stop the shivering. C. Start IV for fluid resuscitation. D. Stop the burning process and remove the ice pack. - ansQuestion 2: D A common error that results in damage to the zone of stasis is the application of ice by a bystander or prehospital care practitioner. When ice is applied to a burn, the patient will experience some reduction in pain; however, the pain relief will be at the expense of additional tissue destruction.
  4. The patient's respiration improves markedly, but he remains confused. He has an absent radial pulse, and his carotid pulse is fast and thready. Your partner asks if he can let the compression go to put in an IV. How should you respond?

Edition ENA Test Bank |Graded A+ pass

A. Preoxygenate to maximize oxygen saturation. B. Place the patient in a "sniffing"position. C. Clear the mouth of any obstructions. D. Prepare the patient for immediate transport. - ansQuestion 2: A Before insertion of any invasive airway, the patient is preoxygenated with a high concentration of oxygen using a simple airway adjunct or manual airway procedure.

  1. After exposing the patient, no other burn injuries were found, but blisters have started to form on the hand and the child is crying from pain. How should you manage the blisters? A. Lance the blisters to drain the fluidand relieve the pressure. B. Cover the injury with a dry, loose, sterile dressing, being sure to leave the blisters intact. C. Use a topical antibiotic ointment and firmly wrap the burn injury. D. Establish an IV for fluid resuscitation. - ansQuestion 3: B In the prehospital setting, blisters are generally best left alone during the relatively short transport time. Blisters that have already ruptured should be covered with a clean, dry dressing.
  2. What does the GCS score indicate? A. Mild TBI B. Moderate TBI C. Severe TBI D. No TBI - ansQuestion 3: B A total GCS score of 13 to 15 likely indicates a mild TBI whereas a score of 9 to 12 is indicative of moderate TBI. A GCS score of 3 to 8 suggests severe TBI.
  3. What is the best way to control the bleeding? A. Direct pressure B. Elevation of the arm above the heart C. Tourniquet D. Occlusive dressing - ansQuestion 3: A With venous bleeds, direct pressure isusually sufficient to stop the flow.
  4. When securing a patient to a backboard, which body part should you secure first? A. Head B. Torso C. Legs D. Pelvis - ansQuestion 3: B When immobilizing a patient, you should secure the torso first, then the head, the legs, and the pelvis.
  5. Which of the following is the basis on which a patient's chance of survival is maximized?

Edition ENA Test Bank |Graded A+ pass

A. Preferences B. Phases C. Principles D. Transport - ansQuestion 3: C The science of medicine provides the principles of medical care. Simply stated, principles define the duties required of the prehospital care practitioner in optimizing patient survival and outcome.

  1. While en route to the hospital, you manage to put an 18-gauge IV in the right arm. Your patient is still confused, and you still have no radial pulse. Your next move is to: A. give 1-L fluid bolus. B. give one 250-mL fluid bolus, and then stop. C. give fluid until you get a radial pulse. D. administer TXA. - ansQuestion 3: C Now is the time to titrate IV fluids to restore tissue perfusion. Giving 1 liter blindly could overshoot your target pressure and reinforce internal bleeding. TXA is not a priority, although it can run parallel to fluids.
  2. Why might it be more difficult to deal with an airway obstruction in a child? A. Children have longer tracheas. B. Children have larger heads and tongues so there is a greater potential for airway obstruction. C. Children have smaller heads, so there is less room to clear the obstruction. D. A child's epiglottis is smaller and stiffer than an adult's. - ansQuestion 3: B Children have larger heads and tongues as compared to an adult so there is a greater potential for airway obstruction in a pediatric patient. You must pay special attention to the proper positioning of a pediatric patient to maintain a patent airway.
  3. You are oxygenating a pediatric patient using a properly fitted oxygen mask and the "squeeze-release-release" timing technique. As you watch for the rise and fall of the chest, you check end-tidal CO2 (ETCO2) monitoring aiming to maintain what level? A. Between 40 and 45 mm Hg B. Between 30 and 35 mm Hg C. Between 35 and 40 mm Hg D. The level is irrelevant because capnography is inaccurate in pediatric patients. - ansQuestion 3: C The proper level to maintain is between 35 and 40 mm Hg.
  4. You are transporting a 37-year-old male patient with a suspected intraabdominal bleed. His blood pressure is 70/50 mm Hg (MAP 57), and his skin is pale and diaphoretic. How will you manage fluid resuscitation for this patient? A. Aggressively administer IV fluids to compensate for internal blood loss.

Edition ENA Test Bank |Graded A+ pass

C. Obtain the patient's medical records and resuscitate to his normal blood pressure reading. D. Carefully administer IV fluids to raise the patient's systolic blood pressure to between 80 and 90 mm Hg. - ansQuestion 3: D Abdominal trauma represents one of the key situations in which a balanced resuscitation is indicated. Aggressive administration of IV fluid may elevate the patient's blood pressure to levels that will disrupt any clot that has formed and result in recurrence of bleeding that had ceased because of blood clotting and hypotension. Prehospital care practitioners must achieve a delicate balance: maintain a blood pressure that provides perfusion to vital organs without restoring blood pressure to elevated or even normal ranges, which may reinitiate bleeding sites in the abdomen or pelvis. In the absence of TBI, the target systolic blood pressure is 80 to 90 mm Hg (mean arterial pressure of 60 to 65 mmHg).

  1. After 400 mL of lactated Ringer solution, you get a radial pulse and his level of consciousness improves. The monitor shows heart rate 110 beats/minute, blood pressure 85/60mm Hg, SpO2 95%, ventilation rate 25 breaths/minute. What should you do? A. Give an additional 500 mL of lactated Ringer solution. B. Stop fluids and give 2 g of TXA. C. Give TXA and 500 mL of normal saline. D. Give 2 mg of morphine for analgesia. - ansQuestion 4: B The patient does not need more fluids right now. Giving morphine in a shocked patient is a risky move and could lead to dangerous hypotension.
  2. The patient is wearing long sleeves, and you are having trouble visualizing the wound. What should you do? A. Cut the cloth away from the site until the entire wound site is visible. B. Leave the clothing in place. Put gauze over the wound. C. Remove the patient's shirt. D. Cut through the slash on the sleeve, and use the material as a makeshift tourniquet. - ansQuestion 4: A Clothing can be quickly removed by cutting. You cannot treat what you cannot see.
  3. What is one reason to use capnography as part of your patient reassessment? A. To get accurate readings for blood pressure B. To assure proper ET tube placement C. To measure arterial blood saturation D. To ensure proper placement for needle decompression - ansQuestion 4: B Capnography can monitor proper endotracheal tube placement. It doesn't read blood pressure, so it cannot beused to determine if a patient is hypotensive. Pulse oximetry, not capnography, measures arterial blood saturation. Capnography is not useful in needle decompression.

  1. What type of padding should you provide for this patient? A. Use compressible padding under the shoulders and torso to prevent hyperflexion. B. Use firm padding between the back of the head and the backboard to prevent hyperextension. C. Do not use any padding. It can cause extension or flexion in the neck. D. No padding needed, but to avoid decreased venous return you should tip the backboard to a left lateral position. - ansQuestion 4: B Because the patient is an adult, you should use firm padding between the back of the head and the backboard to prevent hyperextension. You would pad a child's shoulder and torso to prevent hyperflexion, and you would tip the backboard for a pregnant patient to prevent decreased venous return.
  2. When you examine the patient's pupils, you notice the right one is dilated significantly and her motor response on the left is delayed. What does this suggest? A. Coup-countercoup injury B. Hyphema C. Hypoxia D. Uncal herniation - ansQuestion 4: D When the medial portion of the temporal lobe (uncus) is pushed toward the tentorium and puts pressure on the brain stem, herniation compresses CN III, the motor tract, and the reticular activating system on the same side, resulting in a dilated or blown pupil on the same side, motor weakness on the opposite side, and respiratory dysfunction, progressing to coma.
  3. Which of the following is a goal of the Golden Period? A. Provide written documentation from field care to receiving hospital. B. Expedite the field care and transport of the patient. C. Use a team approach for optimal patient care. D. Use the XABCDE approach to patient assessment. - ansQuestion 4: B One of your most importantresponsibilities as a prehospital carepractitioner is to spend as little time onthe scene as possible and expedite yourfield care and transport of the patient.Studies show that the time from injuryto arrival at the appropriate site fordefinitive care is critical to survival.
  4. Why might you consider early mechanical ventilation via bag-mask device in a geriatric patient? A. Shorter tracheas in geriatric patients create the need for ventilation assistance. B. Laxity of the rib cage makes hyperventilation more likely. C. Geriatric patients have greatly limited physiologic reserve. D. Geriatric patients have a greater alveolar surface area of the lungs. - ansQuestion 4: C

These cause... - ans- HIGH levels of EPINEPHRINE cause smooth muscle relaxation in the airways and causes arteriole smooth muscle contractility (potentiating inotrophic effect). EPI also INCREASES heart rate (positive chronotrophic effect), peripheral vasocontriction, and glycogenolysis (breakdown of glycogen stores in liver into glucose for cellular use)

  • NOREPINEPHRINE increases heart rate, vascular tone through alpha- adrenergic receptor activation, and blood flow to skeletal muscle and triggers the release of glucose from energy stores.
