Oxygen NCLEX Questions Questions
Question 1 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.
Question 2 of 5
A patient with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 4 liters per minute via nasal cannula. Which finding should the nurse report immediately?
Correct Answer: D
Rationale: The correct answer is D because lethargy and difficulty in arousing suggest hypoxia, a serious condition that requires immediate attention. This indicates oxygen saturation is inadequate despite oxygen therapy. A: Respiratory rate of 26 breaths per minute is elevated but not an immediate concern. B: Headache and dizziness can be symptoms of hypoxia but do not require immediate action. C: Oxygen saturation of 91% is slightly low but not critically low to warrant immediate intervention.
Question 3 of 5
The nurse teaches a patient about using a nasal cannula at home. Which statement indicates a need for further teaching?
Correct Answer: B
Rationale: The correct answer is B because increasing the flow rate without healthcare provider's recommendation can lead to oxygen toxicity. Choice A is correct as cleaning the cannula weekly is appropriate for hygiene. Choice C is correct as smoking near oxygen is dangerous. Choice D is correct as kinked tubing can disrupt oxygen flow.
Question 4 of 5
A patient develops sudden hemoptysis and dyspnea. What should the nurse do first?
Correct Answer: B
Rationale: The correct answer is B: Place the patient in an upright position. This step is crucial to optimize ventilation and oxygenation by reducing pressure on the lungs and promoting better airflow. Placing the patient upright helps to improve breathing and decrease the risk of aspiration. Calling the rapid response team (A) can be important but should come after ensuring the patient's immediate safety. Applying oxygen via nasal cannula (C) is essential, but positioning the patient upright should be the priority. Assessing for recent anticoagulant use (D) is important for determining potential causes of hemoptysis but does not address the immediate need to improve oxygenation.
Question 5 of 5
A patient with COPD is prescribed oxygen therapy. What is the most important instruction for the patient?
Correct Answer: B
Rationale: The correct answer is B: Monitor oxygen flow rate to ensure it does not exceed the prescribed level. This is crucial because excessive oxygen flow can lead to oxygen toxicity in COPD patients. Monitoring the flow rate ensures the patient receives the right amount of oxygen. A: Using oxygen continuously may not be necessary and can lead to oxygen dependence. C: Increasing oxygen flow during physical activity is not recommended without healthcare provider guidance. D: Removing the nasal cannula during meals can cause a drop in oxygen levels.
