NSG 501 Practice questions for Chapter 39

Oxygenation

ADN-Nursing 1, Fundamentals of Nursing (and Lab, and Clinical Study)

(Westchester Community College)

CH 39 Oxygenation

  1. A nurse is caring for a patient with COPD. What would be an expected finding upon assessment of this patient? A. Dyspnea B. Hypotension C. Decreased respiratory rate D. Decreased pulse rate a. If a problem exists in ventilation, respiration, or perfusion, hypoxia may occur. Hypoxia is a condition in which an inadequate amount of oxygen is available to cells. The most common symptoms of hypoxia are dyspnea (difficulty breathing), an elevated blood pressure with a small pulse pressure, increased respiratory and pulse rates, pallor, and cyanosis.
  2. A nurse is suctioning the nasopharyngeal airway of a patient to maintain a patent airway. For which condition would the nurse anticipate the need for a nasal trumpet? A. The patient vomits during suctioning. B. The secretions appear to be stomach contents. C. The catheter touches an unsterile surface. D. A nosebleed is noted with continued suctioning. d. When nosebleed (epistaxis) is noted with continued suctioning, the nurse should notify the health care provider and anticipate the need for a nasal trumpet. The nasal trumpet will protect the nasal mucosa from further trauma related to suctioning.
  3. A nurse is suctioning an oropharyngeal airway for a patient who vomits when it is inserted. Which priority nursing action should be performed by the nurse related to this occurrence? A. Remove the catheter. B. Notify the primary care provider. C. Check that the airway is the appropriate size for the patient. D. Place the patient on his or her back. a. When a patient vomits upon suctioning of an oropharyngeal airway, the nurse should remove the catheter; it has probably entered the esophagus inadvertently. If the patient needs to be suctioned again, the nurse should change the catheter, because it is probably contaminated. The nurse should also turn the patient to the side and elevate the head of the bed to prevent aspiration.
  1. A nurse working in a long-term care facility is providing teaching to patients with altered oxygenation due to conditions such as asthma and COPD. Which measures would the nurse recommend? Select all that apply. A. Refrain from exercise. B. Reduce anxiety. C. Eat meals 1 to 2 hours prior to breathing treatments. D. Eat a high-protein/high-calorie diet. E. Maintain a high-Fowler's position when possible. F. Drink 2 to 3 pints of clear fluids daily. b, d, e. When caring for patients with COPD, it is important to create an environment that is likely to reduce anxiety and ensure that they eat a high-protein/high-calorie diet. People with dyspnea and orthopnea are most comfortable in a high-Fowler's position because accessory muscles can easily be used to promote respiration. Patients with COPD should pace physical activities and schedule frequent rest periods to conserve energy. Meals should be eaten 1 to 2 hours after breathing treatments and exercises, and drinking 2 to 3 quarts (1.9 to 2.9 L) of clear fluids daily is recommended.
  2. A nurse is assisting a respiratory therapist with chest physiotherapy for patients with ineffective cough. For which patient might this therapy be recommended? A. A postoperative adult B. An adult with COPD C. A teenager with cystic fibrosis D. A child with pneumonia c. Chest physiotherapy may help loosen and mobilize secretions, increasing mucus clearance. This is especially helpful for patients with large amounts of secretions or an ineffective cough, such as patients with cystic fibrosis. Chest physiotherapy has limited evidence for its effectiveness and is not recommended for use in numerous patient populations, including children with pneumonia, adults with COPD, and postoperative adults (Andrews et al., 2013; Lisy, 2014; Strickland et al., 2013).
  3. A nurse is teaching a patient how to use a meter-dosed inhaler for her asthma. Which comments from the patient assure the nurse that the teaching has been effective? Select all that apply. A. "I will be careful not to shake up the canister before using it." B. "I will hold the canister upside down when using it."

C. "I will inhale the medication through my nose." D. "I will continue to inhale when the cold propellant is in my throat." E. "I will only inhale one spray with one breath." F. "I will activate the device while continuing to inhale." d, e, f. Common mistakes that patients make when using MDIs include failing to shake the canister, holding the inhaler upside down, inhaling through the nose rather than the mouth, inhaling too rapidly, stopping the inhalation when the cold propellant is felt in the throat, failing to hold their breath after inhalation, and inhaling two sprays with one breath.

  1. A nurse is caring for a patient with chronic lung disease who is receiving oxygen through a nasal cannula. What nursing action is performed correctly? A. The nurse assures that the oxygen is flowing into the prongs. B. The nurse adjusts the fit of the cannula so it fits snug and tight against the skin. C. The nurse encourages the patient to breathe through the nose with the mouth closed. D. The nurse adjusts the flow rate to 6 L/min or more. c. The nurse should encourage the patient to breathe through the nose with the mouth closed. The nurse should assure that the oxygen is flowing out of the prongs prior to inserting them into the patient's nostrils. The nurse should adjust the fit of the cannula so it is snug but not tight against the skin. The nurse should adjust the flow rate as ordered.
  2. A nurse is securing a patient's endotracheal tube with tape and observes that the tube depth changed during the retaping. Which action would be appropriate related to this incident? A. Instruct the assistant to notify the primary care provider. B. Assess the patient's vital signs. C. Remove the tape, adjust the depth to ordered depth and reapply the tape. D. No action is required as depth will adjust automatically. c. The tube depth should be maintained at the same level unless otherwise ordered by the health care provider. If the depth changes, the nurse should remove the tape, adjust the tube to ordered depth, and reapply the tape.
  3. What action does the nurse perform to follow safe technique when using a portable oxygen cylinder? A. Checking the amount of oxygen in the cylinder before using it

A. Closely assess the patient before, during, and after the procedure. B. Hyperoxygenate the patient before and after suctioning. C. Limit the application of suction to 20 to 30 seconds. D. Monitor the patient's pulse frequently to detect potential effects of hypoxia and stimulation of the vagus nerve. E. Use an appropriate suction pressure (80 to 150 mm Hg). F. Insert the suction catheter no further than 1 cm past the length of the tracheal or endotracheal tube. a, b, d, e. Close assessment of the patient before, during, and after the procedure is necessary to limit negative effects. Risks include hypoxia, infection, tracheal tissue damage, dysrhythmias, and atelectasis. The nurse should hyperoxygenate the patient before and after suctioning and limit the application of suction to 10 to 20 seconds. The nurse should also take the patient's pulse frequently to detect potential effects of hypoxia and stimulation of the vagus nerve. Using an appropriate suction pressure (80 to 150 mm Hg) will help prevent atelectasis related to the use of high negative pressure. Research suggests that insertion of the suction catheter should be limited to a predetermined length (no further than 1 cm past the length of the tracheal or endotracheal tube) to avoid tracheal mucosal damage, including epithelial denudement, loss of cilia, edema, and fibrosis
