A nurse is preparing to administer a nasogastric (NG) tube feeding to a school-age child. Which of the following actions should the nurse plan to take?

Rationale:

A. "You will need to change the IV dressing site once per week.": Central line dressings for TPN are typically changed every 48–72 hours for gauze or every 5–7 days for transparent dressings, or sooner if the dressing becomes damp, loose, or soiled, to reduce infection risk.

B. "You will need to warm the solution in the microwave before administration.": TPN solutions should never be microwaved due to the risk of uneven heating and nutrient degradation. They should be administered at room temperature.

C. "You will need to weigh the client twice per week.": Clients receiving TPN require daily weights to monitor fluid balance, nutritional status, and detect fluid retention or dehydration promptly. Twice-weekly measurements are insufficient for close monitoring.

D. "You will need to monitor the client's electrolytes daily.": TPN can cause rapid changes in fluid and electrolyte balance, so daily electrolyte monitoring allows timely adjustments to prevent complications such as hypo- or hypernatremia, hypokalemia, and metabolic imbalances.

A. Apply lidocaine gel around the incision: Topical lidocaine is generally used for localized superficial pain, not for deep postoperative pain following major joint surgery. Its effectiveness for a knee arthroplasty incision is limited.

B. Attach a transcutaneous electrical nerve stimulation unit around the incision: TENS units can help with some types of pain but are more effective for chronic musculoskeletal pain rather than acute postoperative pain.

C. Place a cold pack over the incision: Cold therapy reduces inflammation, swelling, and pain in the immediate postoperative period. It is a safe and effective nonpharmacological intervention for mild to moderate pain following knee arthroplasty.

D. Assist the client for a walk in the hallway: Early ambulation is important for preventing complications and promoting recovery, but it may initially increase pain when the client is only 4 hours post-surgery. Cold therapy is more appropriate for immediate pain relief.
