Final answer:
To assess the sleep pattern of a 22-year-old male client, the nurse should inquire about the times he usually goes to bed and wakes up, as this establishes the amount of sleep he is getting.
Step-by-step explanation:
When a 22-year-old male client shares with the nurse that he is always tired, and the nurse needs to assess the client's sleep pattern to determine the quantity of sleep he is getting, the appropriate question to ask is B. "What time do you usually go to bed?" and C. "What time do you usually get up?".
These questions help establish a sleep schedule and quantify the actual hours of sleep obtained. Questions regarding sleep quality and bedtime rituals can also provide insights into sleep disorders such as insomnia but are secondary to establishing basic sleep quantity.
