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.

A. Diarrhea B. Hypoglycemia C. Hypovolemia D. Erythema at the site

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.
