Question 1 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 2 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 3 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.
Question 4 of 5
The nurse assesses a patient diagnosed with idiopathic pulmonary arterial hypertension (IPAH). Which finding requires the most immediate action?
Correct Answer: C
Rationale: The correct answer is C because the discontinuation of epoprostenol infusion in a patient with IPAH can lead to a sudden and severe worsening of symptoms, including potentially life-threatening pulmonary hypertension crisis. This requires immediate action to prevent complications. A: An O2 saturation of 90% is within an acceptable range and does not indicate an immediate crisis. B: A blood pressure of 98/56 mm Hg is slightly low but not critically abnormal to require immediate intervention. D: A prolonged INR may indicate altered coagulation but is not an immediate concern compared to the abrupt discontinuation of a critical medication like epoprostenol.
Question 5 of 5
Which instruction is most important to include in discharge teaching for a patient with chronic obstructive pulmonary disease (COPD)?
Correct Answer: A
Rationale: The correct answer is A: Use pursed-lip breathing during activities. Pursed-lip breathing helps COPD patients improve breathing efficiency by reducing air trapping. It slows down breathing rate and helps control shortness of breath during activities. This instruction is crucial for managing COPD symptoms. Choice B is incorrect because increasing oxygen flow rate without medical advice can be harmful and is not recommended as a self-management strategy for COPD. Choice C is incorrect as limiting fluid intake can lead to dehydration and worsen COPD symptoms. Choice D is incorrect as vaccinations are crucial for COPD patients to prevent respiratory infections and complications.
