A nurse is teaching a client who has a new prescription for fluoxetine to treat depression. Which of the following statements by the client indicates an understanding of the teaching?

A. "I'll take this medicine first thing in the morning.": Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) that can have stimulating effects, which may interfere with sleep if taken later in the day. Therefore, it is usually recommended to take fluoxetine in the morning. B. "I should not take this medicine with grapefruit juice.": Unlike some medications (like certain statins or calcium channel blockers), fluoxetine does not have a significant interaction with grapefruit juice. There is no need to avoid grapefruit juice while taking fluoxetine. C. "I'll take this medicine with food.": Fluoxetine can be taken with or without food, and there is no specific requirement to take it with food. Some people may take it with food if they experience gastrointestinal upset, but it is not a strict instruction. D. "I should expect to feel better after 24 hours of starting this medication.": Antidepressants like fluoxetine typically take 1-2 weeks to start showing effects, and it may take 4-6 weeks to experience full therapeutic benefits.
