Correct Answer is D

Explanation

A. Monitoring weight weekly is important for tracking nutritional status but does not directly prevent adverse effects of TPN.

B. Performing blood glucose monitoring hourly is excessive unless the client has a significant issue with blood glucose control.

C. Changing the IV dressing every 96 hours is too long; the dressing should be changed every 48–72 hours to prevent infection.

D. Changing the IV tubing every 24 hours is correct to reduce the risk of infection and contamination in TPN administration.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"B"}

Explanation

Levothyroxine is best absorbed on an empty stomach, typically taken 30–60 minutes before breakfast, and separately from other medications, especially multivitamins (iron and calcium) and esomeprazole (a proton pump inhibitor). The client has been taking levothyroxine after breakfast with other medications, which can interfere with its absorption. This leads to the risk of decreased therapeutic effectiveness, even though the current TSH is within normal range and free T4 is at the high end of normal.

Multivitamins (often contain calcium or iron): Can bind to levothyroxine and reduce its absorption. Esomeprazole: Alters gastric pH, which can impair levothyroxine absorption. Food intake: Taking levothyroxine with food reduces its bioavailability.
