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?
The client's blood pressure is within the expected reference range.
The client reports a recent weight gain.
The client reports an increase in mood.
The client's legs are not swollen.
The Correct Answer is C
A. While maintaining blood pressure within the expected range is important, it does not specifically indicate the effectiveness of sertraline, which is an antidepressant.
B. Weight gain can occur with some antidepressants, but it is not a direct indicator of their effectiveness.
C. An increase in mood is a primary goal of treatment with sertraline, and reporting this improvement suggests that the medication is having a positive effect.
D. The absence of swollen legs is not a relevant indicator for assessing the effectiveness of sertraline, as it does not relate to mood or depression symptoms.

Correct Answer is B
Explanation
A. Discontinuing metformin 24 hours before a CT scan is longer than necessary and not standard practice.
B. It is generally recommended that metformin be held for at least 12 hours before the administration of IV contrast to reduce the risk of lactic acidosis, especially in clients with renal impairment.
C. Six hours is insufficient time to ensure the medication is cleared from the system, considering the potential risks.
D. Discontinuing metformin for 48 hours is overly cautious and not necessary unless there are complications that arise after the contrast is administered.
Correct Answer is B
Explanation
A. Diarrhea is not a direct risk of stopping TPN abruptly.
B. Abruptly stopping TPN can cause hypoglycemia because the high glucose content in TPN leads to increased insulin production. Without the continuous glucose infusion, blood sugar levels can drop rapidly.
C. Hypovolemia is not a common outcome from stopping TPN suddenly.
D. Erythema at the site is unrelated to the cessation of TPN and more commonly related to local site reactions or infection.
