Step-by-step explanation:
The client's statement that indicates an understanding of the teaching about fluoxetine, a medication used to treat depression, is "C) It may take a few weeks for the full effects of the medication to occur." Fluoxetine is a Selective Serotonin Reuptake Inhibitor (SSRI) which inhibits the reuptake of the neurotransmitter serotonin, causing an increased presence of serotonin in the synapse.
This action can gradually elevate mood, which is beneficial in treating depression. Moreover, it is important to maintain consistent use of the medication even if symptoms improve and not to stop taking it abruptly as this can lead to withdrawal symptoms or a relapse of depression. Grapefruit juice should be avoided as it can interact with the medication and stopping medication once mood stabilizes without consulting a doctor can lead to a recurrence of symptoms.
