Oxygen NCLEX Questions Questions
Question 1 of 5
The nurse is caring for a patient who has a new tracheostomy. Which finding would require immediate action?
Correct Answer: D
Rationale: The correct answer is D because oxygen saturation dropping to 85% indicates hypoxemia, which is a life-threatening emergency requiring immediate intervention to prevent tissue damage and ensure adequate oxygenation. Tracheostomy ties being loose (A) can be addressed promptly but do not pose an immediate threat. A small amount of bleeding at the site (B) is common initially and can be managed with pressure. Thick and dry tracheal secretions (C) may require intervention but do not warrant immediate action like severe hypoxemia.
Question 2 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 3 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 4 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.
Question 5 of 5
Which instruction is most important for a patient with COPD using long-term oxygen therapy?
Correct Answer: B
Rationale: The correct answer is B: Do not adjust oxygen levels without consulting a provider. This is crucial because improper adjustments can lead to oxygen toxicity or inadequate oxygenation. Patients with COPD may have varying oxygen needs, so consulting a provider ensures appropriate therapy. A: Increasing oxygen flow during exercise may be necessary, but adjusting it without guidance can be harmful. C: Removing the nasal cannula during meals is not recommended as it may lead to oxygen desaturation. D: Limiting oxygen use to nighttime only is not suitable as COPD patients may require oxygen therapy throughout the day based on their condition.
