A nurse is assessing a client who has been taking sertraline (Zoloft) for 2 weeks. The nurse should identify which of the following findings as an indication that the medication is effective?

Choice A reason: The client's blood pressure being within the expected reference range does not indicate the effectiveness of sertraline, which is an antidepressant. While maintaining normal blood pressure is important for overall health, it is not a measure of the efficacy of an antidepressant like sertraline. This finding is unrelated to the primary therapeutic effects of the medication. Choice B reason: A recent allergy to nuts is also unrelated to the effectiveness of sertraline. Allergic reactions are independent of the medication's impact on mood and are not relevant indicators of an antidepressant's efficacy. Therefore, this finding does not provide any useful information about the success of the treatment. Choice C reason: An increase in mood is a direct indication that sertraline is effective. Sertraline is a selective serotonin reuptake inhibitor (SSRI) used to treat depression, anxiety, and other mood disorders by increasing serotonin levels in the brain. Improvement in mood and reduction of depressive symptoms are the primary goals of this medication, making this finding a relevant measure of its effectiveness. Choice D reason: The absence of leg swelling is not an indicator of the effectiveness of sertraline. While leg swelling can be a symptom of various conditions, it is not related to the treatment of depression or the efficacy of SSRIs. Therefore, this finding does not provide any information about how well sertraline is working to treat the client's condition.
