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?
Decreased calcium level
Decreased potassium level
Elevated sodium level
Elevated magnesium level
The Correct Answer is B
A. Postoperative ileus and NG tube drainage are not typically associated with decreased calcium levels.
B. The nurse should monitor for electrolyte imbalances, particularly a decreased potassium level. This is because the gastrointestinal tract, especially the stomach, contains a high concentration of potassium, and substantial losses can occur with ongoing gastric suctioning.
C. NG tube drainage does not typically result in elevated sodium levels.
D. NG tube drainage does not typically result in elevated magnesium levels.

Correct Answer is B
Explanation
A. Blood urea nitrogen (BUN) can be affected by factors other than renal function, such as hydration status and protein intake.
B. Serum creatinine is a more specific indicator of renal function because it reflects the glomerular filtration rate (GFR). Elevated levels indicate impaired renal function.
C. Urine-specific gravity can provide some information about renal concentrating ability but is not as specific or sensitive as serum creatinine for assessing overall renal function.
D. Serum sodium levels may be affected by various factors, including hydration status and medications, but they do not directly reflect renal function.
