A nurse is assessing a client who thinks they have sleep apnea. Which of the following questions should the nurse ask?

A. "Do you snore loudly?": Loud snoring is a common symptom of sleep apnea, particularly obstructive sleep apnea. The nurse should inquire about snoring, as it may indicate airway obstruction during sleep, a key feature of the condition. B. "What time do you go to bed?": While bedtime habits are relevant to sleep hygiene, the specific timing of going to bed is not as directly related to diagnosing sleep apnea. Other questions, such as snoring or breathing patterns, are more relevant for this assessment. C. "How often do you have trouble sleeping?": Trouble sleeping can be a symptom of various sleep disorders, but it is not specific to sleep apnea. The nurse should focus on symptoms like snoring, choking, or stopping breathing during sleep, which are more indicative of sleep apnea. D. "Do you fall asleep unexpectedly?": Falling asleep unexpectedly may suggest excessive daytime sleepiness, which can be a result of sleep apnea. However, snoring is a more direct and common symptom of sleep apnea that should be prioritized in the initial assessment.
