Complications of total parenteral nutrition include which of the following?
Complications of total parenteral nutrition include which of the following?
Show Hint
Both a sugar problem and a potassium problem are classic metabolic hazards of TPN.
Updated On: Jun 24, 2026
- Hyperglycemia
- Hyperkalemia
- Hyperosmolar dehydration
- a and b
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: Because TPN infuses a dense nutrient mixture straight into the bloodstream, the body must handle a large glucose and electrolyte burden, and this is where most adverse effects arise.
Step 2: The heavy sugar content commonly causes high blood glucose when endogenous insulin cannot keep pace, marking hyperglycemia as a true complication.
Step 3: Electrolyte swings are equally typical, and potassium can rise to hyperkalemia (or fall) depending on the bag composition and kidney function, confirming the second listed effect.
Step 4: With both glucose and potassium derangements being established hazards, the combined choice a and b is correct. Additional well-known problems span fluid overload, raised urea, cholestatic liver injury, and micronutrient deficiencies.
\[\boxed{\text{a and b (Hyperglycemia and Hyperkalemia)}}\]
