Question 1 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 2 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 3 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.
Question 4 of 5
A client with COPD is scheduled for pulmonary function testing. What instruction should the nurse provide?
Correct Answer: A
Rationale: The correct answer is A because bronchodilators can affect the results of pulmonary function testing. By instructing the client not to use bronchodilators 6-12 hours before the test, we ensure more accurate results. Option B is incorrect as fasting is not necessary for this test. Option C is incorrect because some exercise may be beneficial for the test. Option D is incorrect as wearing loose clothing is not a specific requirement for pulmonary function testing.
Question 5 of 5
A client with cystic fibrosis is prescribed dornase alfa (Pulmozyme). What is the primary therapeutic goal of this medication?
Correct Answer: B
Rationale: The primary therapeutic goal of dornase alfa (Pulmozyme) in cystic fibrosis is to thin and loosen mucus secretions. This enzyme helps break down the DNA in thick, sticky mucus, making it easier for the patient to clear their airways. By thinning the mucus, it reduces the risk of blockages, improves airway clearance, and enhances lung function. This directly addresses the underlying issue in cystic fibrosis, which is the buildup of thick mucus in the lungs. Other choices are incorrect because: A: While dornase alfa may indirectly help reduce lung inflammation by improving mucus clearance, its primary goal is not to directly reduce inflammation. C: While dornase alfa may reduce the risk of infections by improving mucus clearance, its primary goal is not to prevent bacterial infections. D: While improved mucus clearance may indirectly help with oxygen absorption, the primary goal of dornase alfa is specifically to
