Question 1 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 2 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 3 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 4 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.
Question 5 of 5
The nurse is assessing a client with emphysema. Which finding is most indicative of this condition?
Correct Answer: B
Rationale: The correct answer is B: Barrel-shaped chest. In emphysema, the destruction of lung tissue leads to hyperinflation and increased lung volume, resulting in a barrel-shaped chest. This finding is characteristic of emphysema and distinguishes it from other respiratory conditions. A: Productive cough with thick sputum is more indicative of chronic bronchitis. C: Inspiratory crackles in lung bases are more commonly associated with conditions like pneumonia or heart failure. D: Peripheral cyanosis is a sign of poor circulation or decreased oxygen levels in the blood, not specific to emphysema. In summary, the barrel-shaped chest is the most specific and characteristic finding of emphysema, while the other choices are more commonly associated with different respiratory conditions.
