Final answer:
The client needs further instructions if they believe they should wear their glasses at all times, including when they sleep.
Step-by-step explanation:
The correct answer is A. "I will wear my glasses at all times, including when I sleep."
Wearing glasses while sleeping is not necessary and can even be dangerous. It can cause discomfort, increase the risk of damage to the glasses, and lead to pressure on the eyes or face while sleeping.
It's important for the client to follow the nurse's instructions and wear the glasses during waking hours or when engaging in activities that require clear vision.
