Oxygen Cycle Questions and Answers Questions
Question 1 of 5
A nurse is monitoring a client who is receiving mechanical ventilation. Which of the following assessments should the nurse prioritize?
Correct Answer: C
Rationale: The correct answer is C: Arterial blood gas levels. Monitoring arterial blood gas levels is crucial in assessing the client's oxygenation and ventilation status, which are directly affected by mechanical ventilation. It provides important information about the client's acid-base balance and respiratory function. This assessment helps the nurse make timely interventions to optimize ventilation support. Choice A: Skin integrity is important but not the priority when the client's respiratory status is unstable. Choice B: Blood pressure is important but not as critical as assessing oxygenation and ventilation status in a client on mechanical ventilation. Choice D: Fluid balance is important, but monitoring arterial blood gas levels takes precedence in this scenario as it directly reflects the effectiveness of mechanical ventilation.
Question 2 of 5
A client is being evaluated for obstructive sleep apnea. Which assessment finding supports this diagnosis?
Correct Answer: A
Rationale: The correct answer is A: Daytime sleepiness and snoring. Daytime sleepiness is a common symptom of obstructive sleep apnea due to disrupted sleep patterns. Snoring is also a typical sign as it indicates airway obstruction during sleep. Morning headaches and blurred vision (choice B) can be associated with sleep apnea but are not specific. Intermittent chest pain at night (choice C) is more indicative of other conditions like acid reflux or heart issues. Difficulty falling asleep (choice D) is not a classic symptom of obstructive sleep apnea.
Question 3 of 5
The nurse is providing discharge teaching for a client with tuberculosis. Which statement indicates correct understanding?
Correct Answer: C
Rationale: The correct answer is C: "I need to schedule regular follow-up sputum tests." This is correct because regular sputum tests are necessary to monitor the effectiveness of TB treatment and to ensure the disease is not spreading. Choice A is incorrect as masks are not generally needed at home. Choice B is wrong because stopping medication early can lead to drug resistance. Choice D is inaccurate as spicy foods do not affect TB treatment. Regular sputum tests are essential for monitoring progress and adjusting treatment if needed.
Question 4 of 5
A client with COPD is receiving oxygen at 4 L/min via nasal cannula. The client reports headache and drowsiness. What is the nurse's priority action?
Correct Answer: B
Rationale: The correct answer is B: Assess the client's oxygen saturation level. Headache and drowsiness can indicate oxygen toxicity due to excessive oxygen administration in COPD patients. Assessing the oxygen saturation level will help determine if the client is experiencing oxygen toxicity. If the oxygen saturation is high, decreasing the oxygen flow rate (choice A) may be necessary. Encouraging deep breaths (choice C) is not the priority in this situation. Notifying the healthcare provider (choice D) can be done after assessing the oxygen saturation level.
Question 5 of 5
A client with asthma is prescribed a long-acting beta2-agonist. What is the primary purpose of this medication?
Correct Answer: C
Rationale: The correct answer is C: To prevent nocturnal asthma symptoms. Long-acting beta2-agonists help to relax and open the airways, preventing nocturnal asthma symptoms by maintaining bronchodilation throughout the night. This medication is not used for acute relief of bronchospasm (choice A), reducing airway inflammation (choice B), or thinning mucus secretions (choice D). It is specifically indicated for long-term control and prevention of asthma symptoms.
