Question 1 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 2 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 3 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 4 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.
Question 5 of 5
The nurse teaches a patient about pulmonary spirometry testing. Which statement, if made by the patient, indicates teaching was effective?
Correct Answer: C
Rationale: The correct answer is C because inhaling deeply and blowing out hard during pulmonary spirometry testing ensures accurate lung function measurements. This technique maximizes the volume of air exhaled, providing reliable test results. Choice A is incorrect because using an inhaler right before the test can affect the test results. Choice B is incorrect as fasting is not necessary for this test. Choice D is incorrect as blood pressure and pulse monitoring are not typically part of pulmonary spirometry testing.
