Updated On: Jun 24, 2026
- Hyperglycemia
- Hyperkalemia
- Hyperosmolar dehydration
- a and b
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Total parenteral nutrition (TPN) delivers a concentrated glucose, lipid, electrolyte, and protein solution directly into a central vein, so its complications are largely metabolic and electrolyte related.
Step 2: The high dextrose load can outstrip insulin response and cause hyperglycemia, which is one of the most frequent metabolic problems. So option A is correct.
Step 3: TPN also drives a range of electrolyte disturbances, including hyperkalemia and hypokalemia depending on the formulation and the patient's renal status. So option B is also correct.
Step 4: Since both hyperglycemia and hyperkalemia are recognised complications, the best answer is option D, a and b. Other complications include azotemia, fluid overload, liver dysfunction, metabolic bone disease, and trace-element or vitamin deficiencies.
