A young adult tells the nurse in the provider's office that he is concerned about the amount of sleep he is getting. The nurse should explain that which of the following durations is the average recommendation for sleep for a young adult?

The correct answer is A: 8 hr. The average recommendation for sleep for a young adult is typically around 7-9 hours per night. This amount allows for adequate rest and helps maintain overall health and well-being. Choice B (11 hr), C (12 hr), and D (14 hr) are excessive amounts of sleep that are not necessary for young adults and could potentially lead to negative effects such as grogginess or difficulty waking up. Therefore, option A is the most appropriate and balanced choice for a young adult's sleep duration.
