Question 1 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 2 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 3 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 4 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.
Question 5 of 5
The nurse is caring for a client with acute respiratory distress syndrome (ARDS) on mechanical ventilation. Which intervention is most effective in preventing ventilator-associated pneumonia (VAP)?
Correct Answer: B
Rationale: The correct answer is B: Providing oral care with chlorhexidine. This intervention is effective in preventing VAP because it helps reduce the risk of bacterial colonization in the oral cavity, which can lead to aspiration of pathogens into the lungs. Proper oral care helps maintain oral hygiene and reduces the risk of ventilator-associated pneumonia. A: Performing hand hygiene before client care is important for preventing the spread of infections, but it directly does not prevent VAP. C: Suctioning the endotracheal tube every hour is necessary for maintaining airway patency but does not directly prevent VAP. D: Administering prophylactic antibiotics is not recommended as a routine practice for preventing VAP due to the risk of antibiotic resistance and other complications.
