Oxygenation NCLEX Questions Quizlet Questions
Question 1 of 5
The nurse would expect to see increased ventilations if a patient exhibits
Correct Answer: B
Rationale: The correct answer is B: Decreased carbon dioxide levels. When carbon dioxide levels decrease in the body, it signals the need for increased ventilation to remove excess carbon dioxide. This is known as the respiratory drive. Increased oxygen saturation (choice A) would not directly trigger increased ventilations. Decreased pH (choice C) is a sign of acidosis and may lead to increased respiratory rate, but the primary trigger for ventilation is the carbon dioxide levels. Increased hemoglobin levels (choice D) would not directly influence the need for increased ventilations.
Question 2 of 5
A nurse is teaching a client about the purpose of pursed-lip breathing. Which of the following explanations should the nurse provide?
Correct Answer: D
Rationale: The correct answer is D: To improve carbon dioxide elimination. Pursed-lip breathing involves exhaling through pursed lips to create back pressure, helping to keep airways open longer and improving carbon dioxide elimination. This technique reduces the work of breathing and can be beneficial for clients with chronic obstructive pulmonary disease (COPD) or other respiratory conditions. Explanation for other choices: A: To increase oxygen intake - Pursed-lip breathing primarily helps with exhaling, not increasing oxygen intake. B: To promote relaxation - While pursed-lip breathing can promote relaxation by slowing down breathing and reducing anxiety, its primary purpose is related to respiratory function. C: To strengthen respiratory muscles - Pursed-lip breathing mainly focuses on improving breathing efficiency rather than strengthening respiratory muscles.
Question 3 of 5
A client with COPD is prescribed a high-calorie, high-protein diet. What instruction should the nurse provide?
Correct Answer: A
Rationale: Rationale: A client with COPD may have difficulty breathing while eating due to increased energy expenditure. Instructing them to avoid drinking fluids during meals can prevent feeling full quickly, aiding in consuming more calories and proteins. Choices B and C may lead to increased discomfort during eating. Choice D is incorrect as fat intake does not directly impact oxygen consumption in COPD.
Question 4 of 5
The nurse is providing education about smoking cessation. Which strategy is most effective for long-term success?
Correct Answer: B
Rationale: The correct answer is B: Joining a support group for smokers. This strategy is most effective for long-term success because it provides emotional support, accountability, and motivation. Support groups offer a sense of community, understanding, and shared experiences, which can help individuals stay committed to quitting smoking. Nicotine patches (choice A) may help with withdrawal symptoms initially, but long-term success often requires more than just nicotine replacement therapy. Switching to e-cigarettes (choice C) is not a recommended strategy for smoking cessation as it still involves nicotine and may not address the underlying addiction. Gradually reducing cigarette use (choice D) is less effective as it prolongs the process and may not lead to complete cessation. Support groups provide a comprehensive approach to quitting smoking by addressing both the physical and psychological aspects of addiction.
Question 5 of 5
The nurse is providing education to a client with asthma. What should the nurse emphasize to prevent asthma attacks?
Correct Answer: D
Rationale: The correct answer is D. Using a peak flow meter to monitor lung function helps the client track their asthma symptoms and adjust treatment accordingly. This empowers the client to take proactive measures to prevent asthma attacks. Option A is incorrect because regular exercise is beneficial for asthma management. Option B is incorrect as short-acting bronchodilators are used for quick relief, not as a daily preventive measure. Option C is incorrect as adequate hydration helps prevent mucus buildup in the airways.
