Oxygen NCLEX Questions Questions
Question 1 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 2 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.
Question 3 of 5
The nurse is preparing a client for discharge after a thoracentesis. Which instruction is most important?
Correct Answer: A
Rationale: The correct answer is A: Avoid lifting heavy objects for 48 hours. After a thoracentesis, the client should avoid lifting heavy objects to prevent strain on the puncture site, reducing the risk of bleeding or injury. Lifting heavy objects can increase the risk of complications. Choices B, C, and D are not as crucial as A for immediate post-procedure care. Increasing fluid intake is important for hydration but not the most important instruction. Reporting signs of infection and performing deep breathing exercises are important but do not directly relate to the risk of injury post-thoracentesis.
Question 4 of 5
The nurse is assessing a client with tuberculosis (TB). Which symptom is most commonly associated with this condition?
Correct Answer: A
Rationale: The correct answer is A: Night sweats and weight loss. These symptoms are most commonly associated with tuberculosis (TB) due to the chronic infection causing systemic effects leading to night sweats and weight loss. Option B, nosebleeds, is not typically a symptom of TB. Option C, sudden chest pain, is more commonly associated with other conditions like pneumonia or heart-related issues. Option D, bright red blood in sputum, is more indicative of conditions such as pulmonary embolism or lung cancer rather than TB.
Question 5 of 5
A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry (SpO2) indicates that the O2 saturation is 94%. Which action should the nurse expect to take next?
Correct Answer: D
Rationale: The correct answer is D: Obtain repeat arterial blood gases (ABGs). In metabolic alkalosis, ABGs help determine the pH status and electrolyte levels. Repeat ABGs are needed to monitor the patient's condition closely. Choice A is not the immediate priority. Choice B is not indicated for metabolic alkalosis. Choice C is unnecessary without knowing the ABG results.
