A nurse is reviewing a client's laboratory results for effectiveness of total parenteral nutrition (TPN). Which of the following laboratory values is the best indicator for the nurse to monitor for short-term effectiveness of the TPN?

Choice A Rationale: Vitamin A is essential for healthy skin, hair, nails, and bones, and acts as an antioxidant. However, excessive amounts can be harmful and even modest doses previously considered safe can increase the risk of fracture.
Choice B Rationale: Fortified milk, fatty fish, and cheese are rich in calcium and vitamin D, which are crucial for bone health. Calcium is necessary for bone strength, while vitamin D is required for calcium absorption in the body.
Choice C Rationale: While a calcium supplement can help maintain bone density and reduce the risk of fractures, it is generally recommended to get calcium from dietary sources for better absorption and additional nutrients.
Choice D Rationale: Orange juice, lean meats, and egg whites can contribute to overall health, but they do not directly address bone health as effectively as options rich in calcium and vitamin D. Orange juice can be beneficial if fortified, but lean meats and egg whites are not primary sources of calcium or vitamin D.

A. Raw celery and tomatoes are not recommended in the early postoperative period following gastric bypass surgery due to their high fiber content, which may be difficult to tolerate.
B. Drinking at least 100 ounces of fluids per day may be excessive and can increase the risk of complications such as dumping syndrome in the early postoperative period following gastric bypass surgery. Fluid intake should be carefully monitored and follow the healthcare provider's recommendations.
C. Consuming liquids or pureed foods in the early postoperative period following gastric bypass surgery allows the gastrointestinal tract time to heal and adjust to the changes from the surgery. This statement indicates an understanding of the appropriate dietary progression after surgery.

D. The amount of protein intake may vary depending on individual factors and should be guided by the healthcare provider's recommendations. However, focusing solely on protein intake does not address the need for a gradual dietary progression in the early postoperative period.
