Which nursing intervention is most appropriate when administering IV potassium chloride?

Mix with a dextrose solution only

Administer as a rapid IV push

Monitor for signs of hypernatremia

Ensure the infusion diluted and given via an IV pump

Answer and Explanation

The Correct Answer is D

Rationale:

A. Mix with a dextrose solution only: Potassium can be mixed in various compatible solutions (such as 0.9% NS or D5½NS). There is no requirement that potassium chloride must be mixed only with dextrose-containing fluids.

B. Administer as a rapid IV push: This is dangerous and contraindicated. IV potassium must never be given as a rapid IV push or bolus, as it can cause fatal cardiac arrhythmias. It must be diluted and administered slowly.

C. Monitor for signs of hypernatremia: While electrolyte monitoring is important, hypernatremia is not the main concern when administering potassium. The nurse should focus on monitoring potassium levels and cardiac status.

D. Ensure the infusion is diluted and given via an IV pump: IV potassium chloride must always be diluted in an appropriate IV fluid and administered via an infusion pump to control the rate and avoid complications such as arrhythmias and vein irritation. Also, the infusion rate should typically not exceed 10 mEq/hr through a peripheral vein.

Correct Answer is A

Explanation

Rationale:

A. TUMS (calcium carbonate) is an alkaline antacid. Excessive use can lead to increased bicarbonate levels in the blood, causing metabolic alkalosis, especially when used to neutralize gastric acid frequently.

B. Metabolic acidosis would be more likely with diarrhea, renal failure, or overuse of acidic substances, not antacids.

C. Respiratory acidosis is caused by hypoventilation and CO₂ retention, such as in chronic lung disease, not by taking antacids.

D. Respiratory alkalosis is associated with hyperventilation, anxiety, or high altitude—not relevant to antacid use.

A. Chloride B. Calcium C. Potassium D. Magnesium

Correct Answer is A

Explanation

Rationale:
A. Chloride levels often decrease along with sodium, as they are closely related electrolytes. Hyponatremia is commonly accompanied by hypochloremia.
B. Calcium levels are regulated independently of sodium and are not typically affected by hyponatremia.
C. Potassium may be normal, low, or even high depending on the underlying cause; it is not consistently low with hyponatremia.
D. Magnesium levels do not typically mirror sodium levels and are regulated separately.
