A nurse is caring for a client who is to receive potassium replacement. The provider’s prescription reads, “Potassium chloride 30 mEq in 0.9% sodium chloride 100 mL IV over 30 min.” For which of the following reasons should the nurse clarify this prescription with the provider?

The potassium infusion rate is too rapid.

Another formulation of potassium should be given IV.

Potassium chloride should be diluted in dextrose 5% in water.

The client should be treated by giving potassium by IV bolus.

Answer and Explanation

The Correct Answer is A

According to various guidelines12345, the recommended rate of intravenous potassium replacement is 10-20 mEq/h with continuous ECG monitoring. The maximum rate is 40 mEq/h in emergency situations. The prescription given by the provider exceeds this limit and could cause cardiac arrhythmias or hyperkalemia.

Choice B is wrong because potassium chloride is a common and appropriate formulation of potassium for intravenous administration.

Choice C is wrong because potassium chloride should not be diluted in dextrose 5% in water, as this could cause hyperglycemia or osmotic diuresis.

Choice D is wrong because potassium should never be given by IV bolus, as this could cause cardiac arrest or tissue necrosis.

Correct Answer is D

Explanation

Distended neck veins are a sign of increased central venous pressure, which can result from fluid volume excess. Fluid volume excess can also cause edema, crackles in the lungs, and increased blood pressure.

Choice A is wrong because decreased bowel sounds are not related to fluid volume excess.

Decreased bowel sounds can indicate ileus, obstruction, or peritonitis. Choice B is wrong because bilateral muscle weakness is not a sign of fluid volume excess.

Bilateral muscle weakness can be caused by electrolyte imbalances, neuromuscular disorders, or stroke.

Choice C is wrong because thready pulse is a sign of fluid volume deficit, not excess.

Thready pulse indicates poor perfusion and low cardiac output, which can result from dehydration, hemorrhage, or shock.

A. I should stay upright for at least 15 minutes after taking this medication. B. I should take an antacid with this medication to prevent stomach upset. C. I should take this medication with 8 ounces of milk. D. I should notify my provider if my stools turn black.

Correct Answer is A

Explanation

The client should stay upright for at least 15 minutes after taking ferrous gluconate to prevent oesophagal irritation. Choice B is wrong because taking an antacid with ferrous gluconate can decrease its absorption and effectiveness.

Choice C is wrong because taking ferrous gluconate with milk can also reduce its absorption and cause gastrointestinal distress.

Choice D is wrong because black stools are a common and harmless side effect of ferrous gluconate and do not indicate a need to notify the provider. Ferrous gluconate is an iron supplement used to treat or prevent iron deficiency anaemia, a condition where the body does not have enough red blood cells to carry oxygen to the tissues.

Iron is an essential component of haemoglobin, the protein that carries oxygen in the blood.
