A nurse is caring for a client who reports difficulty sleeping and has a new diagnosis of sleep apnea. Which of the following statements by the client should the nurse expect?

Loud snoring is the hallmark symptom of obstructive sleep apnea (OSA), often reported by the bed partner rather than the client. Other expected findings include excessive daytime sleepiness, morning headaches (not evening), awakening unrefreshed, and witnessed apneic episodes. Clients with OSA feel fatigued (not rested) upon awakening and drowsy (not alert) during the day because sleep is repeatedly interrupted by apneic episodes.
