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 A

Explanation

The correct answer is choice A. Increased pulse rate.

An aPTT of 90 seconds is much higher than the normal range of 30-40 seconds, which means the blood takes longer to clot and the client is at risk of bleeding. An increased pulse rate is a sign of blood loss and shock.

Choice B is wrong because increased blood pressure is not a sign of bleeding, but rather a sign of hypertension or stress.

Choice C is wrong because decreased temperature is not a sign of bleeding, but rather a sign of hypothermia or infection.

Choice D is wrong because decreased respiratory rate is not a sign of bleeding, but rather a sign of respiratory depression or sedation.

A. The client has a BUN level of 18 mg/dL. B. The client reports a history of nausea with cefuroxime. C. The client has a history of a severe penicillin allergy. D. The client takes an aspirin daily.

Correct Answer is C

Explanation

This is the priority for the nurse to report to the provider because cefuroxime is a cephalosporin antibiotic that can cause serious or life-threatening allergic reactions in people who are allergic to penicillin. The nurse should not administer cefuroxime to this client until the provider is notified and an alternative antibiotic is prescribed.

Choice A is wrong because the client has a BUN level of 18 mg/dL, which is within the normal range of 7 to 20 mg/dL.

This does not indicate any renal impairment or adverse reaction to cefuroxime.

Choice B is wrong because the client reports a history of nausea with cefuroxime, which is a common side effect of this drug.

The nurse should instruct the client to take cefuroxime with food to reduce nausea, but this is not a priority to report to the provider.

Choice D is wrong because the client takes aspirin daily, which does not interact with cefuroxime.

The nurse should monitor the client for any signs of bleeding or bruising while taking aspirin, but this is not a priority to report to the provider.
