NCLEX Questions on Oxygenation and Perfusion Questions
Question 1 of 5
The nurse is teaching a patient with asthma about the use of a rescue inhaler. Which statement indicates a need for further teaching?
Correct Answer: B
Rationale: Correct Answer: B Rationale: 1. Taking one puff and waiting 5 minutes before a second puff is incorrect as rescue inhalers are meant for immediate relief during asthma attacks. 2. Choice A is correct as using the inhaler before exercise can prevent exercise-induced symptoms. 3. Choice C is correct as cleaning the mouthpiece prevents clogging and ensures proper functioning. 4. Choice D is correct as using the inhaler when feeling short of breath is the appropriate time for immediate relief.
Question 2 of 5
The nurse teaches a patient about using a peak flow meter. Which statement indicates effective learning?
Correct Answer: B
Rationale: The correct answer is B because blowing into the peak flow meter hard and fast ensures an accurate measurement of peak expiratory flow rate. This technique helps assess the severity of asthma and monitor response to treatment. Choice A is incorrect because using the meter before medication may not reflect actual lung function. Choice C is incorrect as inhaling deeply does not measure lung capacity. Choice D is incorrect because peak flow meters are used for proactive monitoring, not just when feeling short of breath.
Question 3 of 5
The nurse is caring for a patient with a suspected pulmonary embolism. What is the first action?
Correct Answer: B
Rationale: The correct answer is B: Apply oxygen via nasal cannula. This is the first action because in a suspected pulmonary embolism, the priority is to optimize oxygenation to prevent hypoxia. Oxygen therapy helps improve oxygen saturation and tissue perfusion. Administering a bronchodilator (Choice A) would not address the primary issue of oxygenation. Preparing for a chest x-ray (Choice C) may be necessary but not the initial action. Initiating IV fluids (Choice D) may be needed later but does not directly address the immediate concern of oxygenation in a suspected pulmonary embolism.
Question 4 of 5
The nurse observes an air leak in the chest tube system. What is the appropriate action?
Correct Answer: C
Rationale: The correct action is to check the system for loose connections (Choice C). First, ensure that all connections are secure to prevent further air leakage. Clamping the chest tube (Choice A) can create tension leading to more air leaks. Repositioning the chest tube (Choice B) may not address the underlying issue of loose connections. Notifying the healthcare provider (Choice D) is important but addressing the immediate concern of loose connections should be the initial action to prevent complications.
Question 5 of 5
The nurse reviews discharge instructions for a patient with newly diagnosed COPD. Which statement by the patient indicates effective teaching?
Correct Answer: B
Rationale: The correct answer is B because eating smaller meals helps prevent feeling too full, which can worsen breathing difficulties in COPD patients. Step 1: COPD patients often experience shortness of breath, especially when the stomach is full. Step 2: Eating smaller meals can help reduce the pressure on the diaphragm and lungs, making breathing easier. Step 3: This demonstrates the patient's understanding of how diet can impact their respiratory symptoms. Incorrect choices: A: Avoiding physical activity can lead to physical deconditioning, worsening COPD symptoms. C: Using a rescue inhaler before meals is not a standard practice for COPD management. D: Increasing oxygen flow rate without medical guidance can be dangerous and ineffective in managing COPD.
