Question 1 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 2 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 3 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 4 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
Question 5 of 5
The nurse is caring for a client with a pneumothorax and a chest tube. Which action is the priority if the chest tube becomes dislodged?
Correct Answer: B
Rationale: The correct answer is B: Apply a sterile occlusive dressing to the site. This is the priority because it helps prevent air from re-entering the pleural space, maintaining proper negative pressure. Clamping the chest tube (A) can lead to tension pneumothorax. Reinserting the chest tube (C) should only be done by a healthcare provider. Notifying the healthcare provider (D) is important but not the immediate priority.
