A nurse is caring for a client who has a postoperative ileus and an NG tube that has drained 2,500 mL in the past 6 hr. Which of the following electrolyte imbalances should the nurse monitor the client for?

  • A. Decreased potassium level
  • B. Increased sodium level
  • C. Increased calcium level
  • D. Decreased magnesium level
Correct Answer: A

Rationale: The correct answer is A: Decreased potassium level. Postoperative ileus can lead to gastrointestinal fluid losses, causing a decrease in potassium levels due to excessive drainage through the NG tube. Potassium is an important electrolyte for maintaining normal muscle function, including the heart. Monitoring potassium levels is essential to prevent complications such as cardiac arrhythmias.
Incorrect choices:
B: Increased sodium level - Unlikely in this scenario as excessive drainage would lead to fluid and electrolyte loss.
C: Increased calcium level - Unrelated to postoperative ileus and NG tube drainage.
D: Decreased magnesium level - Possible but not as critical as monitoring potassium levels in this situation.
