Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 of 5
The nurse is teaching a client with asthma how to use a peak flow meter. Which instruction should be included?
Correct Answer: A
Rationale: The correct answer is A: Use the meter before taking bronchodilators. This is because measuring peak flow before using bronchodilators provides a baseline measurement of the client's lung function. Taking bronchodilators could artificially improve the results, making it harder to assess the true severity of the asthma. Explanation for why other choices are incorrect: B: Taking a deep breath and exhaling slowly is not necessary for using a peak flow meter. C: Performing the test while lying down can affect the accuracy of the results as the body position can impact lung function. D: Repeating the test and recording the result may not be necessary unless specifically instructed by the healthcare provider.
Question 2 of 5
A client with bronchitis is experiencing increased mucus production. Which intervention is most effective in promoting mucus clearance?
Correct Answer: A
Rationale: The correct answer is A: Encouraging fluid intake of at least 3 liters per day. Increasing fluid intake helps to thin the mucus, making it easier to clear from the airways. Adequate hydration also helps to keep the mucus membranes moist, facilitating mucus clearance. This intervention promotes effective coughing and expectoration, ultimately aiding in clearing the excess mucus associated with bronchitis. Choice B: Administering prescribed antitussive medication would not be effective in promoting mucus clearance as antitussives suppress coughing, which is needed to clear mucus. Choice C: Positioning the client in a high Fowler's position may improve breathing but does not directly address mucus clearance. Choice D: Limiting activity to conserve energy does not promote mucus clearance. In fact, some degree of activity can help mobilize mucus and facilitate its clearance.
Question 3 of 5
A client with pneumonia is receiving antibiotics. Which action should the nurse prioritize?
Correct Answer: A
Rationale: The correct answer is A: Administering antibiotics on schedule. Administering antibiotics on time is crucial to maintain therapeutic levels in the bloodstream, effectively treating the infection. Delay or missing doses can lead to treatment failure. Monitoring for allergic reactions (C) is important but secondary to ensuring timely administration of antibiotics. Encouraging fluid intake (B) is beneficial but not as critical as antibiotic administration. Assessing sputum production (D) is important for evaluating treatment response but should not take precedence over administering antibiotics.
Question 4 of 5
The nurse is planning to care for a client with COPD who has a high anxiety level that causes shortness of breath. Which action should the nurse take given the client's reaction to anxiety?
Correct Answer: B
Rationale: The correct answer is B: Teach pursed-lip breathing to use when feeling anxious. This intervention helps the client manage anxiety-induced shortness of breath by promoting relaxation and improving oxygen exchange. Pursed-lip breathing slows down the client's breathing rate, reduces respiratory rate, and decreases the work of breathing. It also helps to prevent air trapping in the lungs. Administering anti-anxiety medication (Option A) should not be the first-line intervention for managing anxiety-induced shortness of breath. Discouraging visitors (Option C) may isolate the client and not address the underlying issue of anxiety. Teaching proper use of inhalers (Option D) is important for managing COPD symptoms, but it does not directly address anxiety-related shortness of breath.
Question 5 of 5
The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?
Correct Answer: D
Rationale: The correct answer is D. The most important result to report immediately is a pH of 7.31, which indicates acidosis, a potentially life-threatening condition. A low pH can lead to organ dysfunction and requires prompt intervention. The other choices have pH levels within normal limits. PaO2, PaCO2, and O2 saturation are also important, but in this case, the critical value is the pH. Choices A, B, and C have pH values closer to normal range and, although abnormalities in PaO2, PaCO2, or O2 saturation should be monitored, they are not as urgent as a pH indicating acidosis.
