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?

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.

The potassium infusion rate is too rapid.

Answer and Explanation

The Correct Answer is D

A. Another formulation of potassium should be given IV: The type of potassium formulation isn't the issue in this scenario.

B. Potassium chloride should be diluted in dextrose 5% in water: While potassium chloride can be administered in different solutions, the primary concern here is the infusion rate, not the specific diluent.

C. The client should be treated by giving potassium by IV bolus: The concern here is the rate of administration, not the route. Potassium is commonly administered through an IV infusion rather than a bolus due to the risk of cardiac arrhythmias associated with rapid administration.

D. A nurse is caring for a client who is to receive potassium replacement. The nurse should clarify the prescription with the provider because the potassium infusion rate is too rapid.

The prescription indicates that the client should receive potassium chloride 30 mEq in 0.9% sodium chloride 100 mL IV over 30 minutes. This rate of administration is too fast for potassium replacement and could lead to potentially serious complications, such as hyperkalemia or cardiac arrhythmias. The typical recommended rate for potassium replacement is 10-20 mEq/hour, and this prescription exceeds that range.

Correct Answer is A

Explanation

A. Osteoporosis. A nurse is consulting a formulary about a client's new prescription for raloxifene. The medication raloxifene is used to treat osteoporosis. It is a selective estrogen receptor modulator (SERM) that helps to prevent and treat bone loss in postmenopausal women. It works by mimicking the effects of estrogen on bone tissue, helping to prevent bone breakdown and maintain bone density.
B. Urinary tract infection: UTIs are typically treated with antibiotics.
C. Hypothyroidism: Hypothyroidism is treated with thyroid hormone replacement.
D. Deep-vein thrombosis: DVT is typically treated with anticoagulant medications like heparin and warfarin.

Correct Answer is ["0.4"]

Explanation

To calculate the volume of heparin needed, you can use the formula:

Volume (mL) = Desired dose (units) / Concentration (units/mL)

In this case, the desired dose is 4,000 units and the concentration is 10,000 units/mL.

Volume = 4,000 units / 10,000 units/mL = 0.4 mL

So, the nurse should administer 0.4 mL of heparin.
