A nurse is caring for a client who is ordered Potassium 40 mEq IV. On hand is Potassium Chloride 20 mEq/mL. What is the nurse’s next action?

Mix potassium in 1 liter of normal saline.

Call the physician for order clarification.

Prepare 20 mEq of Potassium to give IV push.

Give the medication as ordered.

Answer and Explanation

The Correct Answer is B

A. While potassium is typically diluted in IV fluids, the concentration and infusion rate must be clarified before administration. A standard dilution is 10 mEq in 100 mL or 40 mEq in 1L, but this must be verified.
B. Calling the physician for clarification is the safest step. IV potassium should never be given undiluted or as an IV push due to the risk of fatal cardiac arrhythmias.
C. IV push potassium is never appropriate as it can cause cardiac arrest.
D. Administering the undiluted 20 mEq/mL solution is dangerous and requires proper dilution before administration.

B. Digoxin does not decrease the force of contractions; instead, it strengthens them, making it beneficial for heart failure treatment.
C. Digoxin is commonly used in heart failure management, particularly in cases of systolic dysfunction or atrial fibrillation.
D. Digoxin decreases heart rate by slowing conduction through the atrioventricular (AV) node, making it useful in atrial fibrillation, but its primary benefit in heart failure is increasing contractility.
