2024 PN NCLEX Questions Nursing Practice Question
The physician wants to know if a client is tolerating his total parenteral nutrition. Which of the following laboratory tests is likely to be ordered?
Correct Answer: B
Rationale: Liver function tests are critical in monitoring a client on total parenteral nutrition (TPN) as they assess the liver's ability to process nutrients and detect potential complications like hepatic dysfunction. Elevated liver enzymes can indicate issues related to TPN.
Triglyceride levels (A) are important but primarily monitor fat emulsions rather than overall TPN tolerance. A glucose tolerance test (C) is not routinely used for TPN assessment; it evaluates glucose metabolism rather than nutritional status. A complete blood count (D) provides information on blood components but does not specifically assess TPN tolerance or liver function.
