Oxygen NCLEX Questions Questions
Question 1 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 2 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 3 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 4 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 5 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.
