Oxygen NCLEX Questions Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The nurse observes continuous bubbling in the water-seal chamber of a chest tube. What is the next step?
Correct Answer: C
Rationale: The correct next step is to check for air leaks in the system (Choice C). Continuous bubbling in the water-seal chamber indicates an air leak. By checking for air leaks, the nurse can identify and address the source of the problem, ensuring the chest tube is functioning properly. Clamping the tube (Choice A) can lead to tension pneumothorax. Notifying the healthcare provider (Choice B) should be done after assessing and addressing immediate issues. Adding water to the chamber (Choice D) is incorrect as it can disrupt the water seal and lead to further issues.
Question 5 of 5
Which finding in a patient post-thoracentesis requires immediate intervention?
Correct Answer: A
Rationale: The correct answer is A: Oxygen saturation of 88%. This finding requires immediate intervention because it indicates significant hypoxemia, which can be life-threatening. Hypoxemia can lead to tissue damage and organ failure if not addressed promptly. Oxygen saturation below 90% is considered critically low and requires urgent attention to prevent complications. Summary: - Choice B: Pain rated 6/10 at the site is significant but does not require immediate intervention compared to hypoxemia. - Choice C: Mild tachypnea while lying flat may indicate a potential issue, but it is not as urgent as severe hypoxemia. - Choice D: Draining 300 mL of pleural fluid is a common outcome of thoracentesis and does not warrant immediate intervention unless other symptoms are present.
