Correct Answer is B

Explanation

TPN is a form of intravenous nutrition that provides glucose, amino acids, lipids, vitamins, minerals, and electrolytes to clients who cannot eat or absorb nutrients through their gastrointestinal tract. Discontinuing TPN abruptly can cause a sudden drop in blood glucose levels, leading to hypoglycemia .

Hyperglycemia can occur during TPN administration if the glucose infusion rate is too high or if the client has insulin resistance . Diarrhea can occur as a result of infection, bowel ischemia, or intolerance to enteral feeding . Hypertension can occur due to fluid overload, electrolyte imbalance, or vascular complications .

Correct Answer is B

Explanation

To assess a client for a positive Chvostek’s sign, the nurse should tap gently on the cheek, specifically two centimeters in front of the ear, over the facial nerve (also known as CN VII). This test is used to check for hypocalcemia, a condition that can lead to tetany, which is the involuntary contraction of muscles. A twitch of the facial muscles in response to this tapping indicates a positive Chvostek’s sign. This is particularly relevant following a thyroidectomy, as the procedure can indirectly affect the parathyroid glands, potentially leading to hypocalcemia
