Oxygen NCLEX Questions Questions
Question 1 of 5
The nurse is teaching a client with asthma about the use of a spacer with an inhaler. Which statement indicates correct understanding?
Correct Answer: B
Rationale: The correct answer is B because a spacer helps to increase the amount of medication that reaches the lungs by slowing down the inhalation and reducing the risk of medication depositing in the mouth or throat. Cleaning the spacer once a week with warm soapy water (choice A) is important but does not reflect understanding of how the spacer works. Exhaling into the spacer before inhaling (choice C) is incorrect and can contaminate the spacer. Choice D is incorrect because using a spacer actually helps improve the effectiveness of inhaled medications, not make them less effective.
Question 2 of 5
A nurse is monitoring a client receiving a blood transfusion. Which symptom would indicate a potential transfusion-related acute lung injury (TRALI)?
Correct Answer: B
Rationale: The correct answer is B because sudden onset of dyspnea and hypoxemia are key symptoms of transfusion-related acute lung injury (TRALI). This is a serious complication caused by an inflammatory response to transfused blood products. Dyspnea and hypoxemia signify acute respiratory distress. Fever and chills (A) are more indicative of a transfusion reaction or infection. Generalized itching and rash (C) are symptoms of an allergic reaction. Low blood pressure and bradycardia (D) are more likely signs of a hemolytic reaction or sepsis.
Question 3 of 5
The nurse is assessing a client with acute respiratory distress. Which finding requires immediate intervention?
Correct Answer: B
Rationale: The correct answer is B because an oxygen saturation of 85% indicates severe hypoxemia, which can lead to tissue damage and organ failure. Immediate intervention is needed to improve oxygenation. Choice A (respiratory rate of 28) is slightly elevated but not as critical as severe hypoxemia. Choice C (use of accessory muscles) indicates respiratory distress but not as urgent as low oxygen saturation. Choice D (pulse rate of 110) may be elevated due to the body compensating for hypoxemia but addressing oxygenation is the priority.
Question 4 of 5
The nurse is evaluating a client with emphysema who is on oxygen therapy. Which finding indicates a need for adjustment?
Correct Answer: C
Rationale: The correct answer is C: Drowsiness and confusion. This indicates a need for adjustment in oxygen therapy as it could be a sign of oxygen toxicity. Oxygen saturation of 96% (A) is within the normal range. Respiratory rate of 20 breaths per minute (B) is also normal. Increased dyspnea during exertion (D) is expected in a client with emphysema. Drowsiness and confusion are concerning symptoms that require immediate attention to prevent potential harm.
Question 5 of 5
A client with obstructive sleep apnea is using continuous positive airway pressure (CPAP) therapy. What is the primary benefit of CPAP?
Correct Answer: B
Rationale: The primary benefit of CPAP therapy is maintaining an open airway during sleep. CPAP delivers a continuous stream of air pressure to keep the airway open, preventing apnea episodes. This ensures proper oxygen flow, reduces snoring, and improves sleep quality. Option A is incorrect because CPAP primarily targets airway obstruction, not respiratory infections. Option C is incorrect as CPAP does not directly affect mucus accumulation. Option D is incorrect as CPAP primarily benefits sleep quality rather than oxygen levels during physical activity.
