What should the nurse assess the patient for after discontinuing the TPN?
Explanation & Rationale
Choice A rationaleAbrupt cessation of total parenteral nutrition (TPN) can lead to a rapid decrease in blood glucose levels. While receiving TPN, the body is continuously supplied with glucose. When this external glucose source is suddenly removed, the pancreas may continue to secrete insulin at a rate higher than needed, resulting in hypoglycemia. Signs and symptoms of hypoglycemia include sweating, tremors, confusion, and dizziness.Choice B rationaleHyperthermia, or elevated body temperature above the normal range of approximately 36.5°C to 37.5°C (97.7°F to 99.5°F), is not a typical complication following the discontinuation of TPN. Fever is usually associated with infection or inflammation, neither of which are a direct consequence of stopping TPN.Choice C rationaleFlatulence, or the accumulation of gas in the digestive tract leading to bloating and the passage of gas, is related to dietary intake and digestive processes. Discontinuing TPN, which bypasses the digestive system, would not directly cause an increase in flatulence. In fact, digestive issues might improve once oral or enteral feeding resumes.Choice D rationaleTachycardia, an abnormally rapid heart rate (typically defined as above 100 beats per minute in adults), is not a direct physiological consequence of discontinuing TPN. While changes in fluid balance or electrolyte levels (which can occur with TPN but are monitored closely) could indirectly affect heart rate, hypoglycemia is a more immediate and direct risk upon TPN cessation.
