Final answer:
The nurse should inform the client that taking fluoxetine, an SSRI for treating depression, might lead to difficulties with sexual functioning. Other immediate effects like increased saliva or ringing in the ears are not commonly associated with fluoxetine, and symptom improvement may take several weeks.
Step-by-step explanation:
When teaching a client who has a depressive disorder about fluoxetine, which is a selective serotonin reuptake inhibitor (SSRI) often known by the brand name Prozac, the nurse should include that it might experience difficulties with sexual functioning while taking this medication. Fluoxetine works by increasing the levels of serotonin in the central nervous system, which can lead to a range of side effects. It is important to note that patients should not expect an immediate improvement in symptoms; rather, noticeable improvement in depression may take several weeks. In addition, fluoxetine is not known to cause an excess of saliva or a temporary ringing in the ears when starting the medication. Also, crucially, patients should be aware of the importance of not self-medicating and to report any adverse effects to their healthcare provider.
