Final answer:
Sexual dysfunction is an adverse effect of the medication fluoxetine, a commonly prescribed SSRI for the treatment of depression.
Step-by-step explanation:
The nurse providing follow-up care to a client taking fluoxetine for depression should recognize that sexual dysfunction is an adverse effect of this medication. The common side effects of antidepressants such as fluoxetine, which is an SSRI (Selective Serotonin Reuptake Inhibitor), include weight gain, fatigue, dizziness, loss of sexual desire, nausea, and others. Since fluoxetine is known to inhibit the reuptake of serotonin, thereby increasing serotonin levels in the synapse to enhance mood in the treatment of depression, these side effects should be monitored.
In summary, while fluoxetine can increase energy levels as a result of mood elevation and may sometimes lead to weight loss, euphoria is not typically associated with its use or as an adverse effect. Hence, sexual dysfunction is the finding that the nurse should identify as a side effect linked with fluoxetine.
