A nurse is caring for a client who is postoperative and has an NG tube that has drained 2,500 ml. In the past 6 hr. The nurse should monitor the client for which of the following electrolyte Imbalances?

Decreased potassium level

Decreased calcium level

Elevated magnesium level

Elevated sodium level

Answer and Explanation

The Correct Answer is A

A. Decreased potassium level
NG tube drainage can lead to hypokalemia (low potassium levels) due to the loss of gastric fluids, which contain significant amounts of potassium. This choice is correct.

B. Decreased calcium level
Calcium levels are not directly affected by NG tube drainage.

C. Elevated magnesium level
NG tube drainage does not typically lead to elevated magnesium levels.

D. Elevated sodium level
NG tube drainage can result in hyponatremia (low sodium levels) due to the loss of gastric fluids. Elevated sodium levels are not expected in this situation.

Correct Answer is B

Explanation

A. Blood glucose 150 mg/dL:
This blood glucose level is slightly elevated but not significantly concerning on its own. It may be related to stress or other factors. In the context of acute gastroenteritis, it might be secondary to dehydration, but it is not an immediate priority unless the client is diabetic.

B. Potassium 2.5 mEq/L:
This is the correct answer. Low potassium levels (hypokalemia) are a severe concern, especially in the context of acute gastroenteritis where there can be significant losses through vomiting and diarrhea. Hypokalemia can lead to cardiac arrhythmias and needs urgent correction.

C. Weight loss of 3% of total body weight:
While weight loss is an important parameter, a 3% weight loss is usually not an immediate concern. In cases of acute gastroenteritis, rapid weight loss might indicate severe dehydration, but this choice is not as urgent as addressing a severe electrolyte imbalance like hypokalemia.

D. Urine specific gravity 1.035:
This specific gravity indicates concentrated urine, which could be due to dehydration. While this finding is important and indicates the need for rehydration, it is not as urgent as correcting a critically low potassium level.

A. Place the client in a supine position. B. Withdraw the tube if the client gags during insertion. C. Measure the tube for insertion from the tip of the nose to the umbilicus. D. Instruct the client to place his chin to his chest and swallow.

Correct Answer is D

Explanation

A. Place the client in a supine position.
Placing the client in a high Fowler's position (sitting upright) is the appropriate position for inserting a nasogastric tube. This position helps facilitate the passage of the tube through the nasopharynx and into the esophagus and stomach.

B. Withdraw the tube if the client gags during insertion.
Gagging during insertion is a normal response. Advancing the tube slowly and having the client swallow can help pass the tube through the nasopharynx.

C. Measure the tube for insertion from the tip of the nose to the umbilicus.
The correct measurement for insertion is from the tip of the nose to the earlobe and then down to the xiphoid process (not the umbilicus).

D. Instruct the client to place his chin to his chest and swallow.
This instruction is appropriate. Asking the client to flex their head slightly forward and swallow helps guide the tube into the esophagus.
