Decreased calcium level

Decreased potassium level

Elevated sodium level

Elevated magnesium level

Answer and Explanation

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.
