Step-by-step explanation:
The correct statement by the patient indicating understanding of teaching is:
C) "I may experience an improvement in mood after one dose."
This statement indicates that the patient understands that fluoxetine may take some time to start working and that an improvement in mood may not be immediate. It is important for the patient to know that antidepressant medications, such as fluoxetine, usually take several weeks to start having a noticeable effect. Therefore, the patient's understanding of this delay in response shows comprehension of the teaching.
