57. Maintaining the infusion rate of total parenteral nutrition (TPN) is a nursing responsibility. If the infusion rate is too rapid, which side effects would the nurse observe?
57. Maintaining the infusion rate of total parenteral nutrition (TPN) is a nursing responsibility. If the infusion rate is too rapid, which side effects would the nurse observe?
. Serum sodium and potassium excess.
. Increased blood pressure and hyperglycemia.
. Hypoglycemia and low blood pressure.
. Potassium excess and congestive heart failure.
Test-Taking Tip
Focus on two contradictory options: ↑ BP and hyperglycemia vs. ↓ BP and hypoglycemia. Think "too fast" → "too high."

Answer 1 is incorrect because the increase in vascular volume might result in hemodilution of sodium, not excess. Answer 2 is correct because TPN is a high-glucose and hyperosmolar solution that would result in increased vascular volume. Answer 3 is incorrect because the blood glucose level and blood pressure would increase with rapid infusion, not decrease. Answer 4 is incorrect because an increase in blood pressure and hyperglycemia would occur before hyperkalemia and heart failure.
