A nurse is teaching a client who is obese and has obstructive sleep apnea how to decrease the number of nightly apneic episodes. Which of the following client statements indicates an understanding of the teaching?

Correct Answer: D

Rationale: The correct answer is D because losing weight can help reduce the severity and frequency of obstructive sleep apnea. Excess weight can lead to fat deposits around the upper airway, causing obstruction during sleep. By losing weight, the airway may become less obstructed, reducing apneic episodes. Choice A is incorrect because sleeping on the back can actually worsen sleep apnea by causing the tongue and soft tissues to block the airway. Choice B is incorrect because sleeping pills can relax the muscles in the airway, making it more likely for an individual with sleep apnea to experience episodes of apnea. Choice C is incorrect because while a humidifier can alleviate some symptoms like dryness, it does not directly address the underlying cause of obstructive sleep apnea related to obesity.

Correct Answer: A

Rationale: Nausea and vomiting can lead to metabolic alkalosis due to loss of gastric acid, making it important to report promptly to prevent acid-base imbalances.

Correct Answer: A

Rationale: Touching non-sterile items like masks compromises sterility and requires corrective action.

Correct Answer: B

Rationale: An open pneumothorax occurs when air enters the pleural space through an external opening.

Correct Answer: A
