A client with heart failure is receiving furosemide 40 mg IV. The provider orders 40 mEq of potassium chloride in 100 mL of dextrose 5% in water to infuse over four hours. The client's most recent serum potassium level is 3.0 mEq/L.

At what rate (in mL/h) should the nurse set the IV pump? Record the answer as a whole number.

Answer :

Final answer:

The nurse should set the IV pump at a rate of 10 ml per hour.

Explanation:

To calculate the rate at which the IV pump should be set, we need to determine how much potassium chloride (KCl) is administered per hour and then convert it into milliliters (ml) per hour.

The order is for 40 meq of KCl to be infused over four hours, so that means 40 meq / 4 hours = 10 meq/hour.

To convert from milliequivalents (meq) to milliliters (ml), we need to know the concentration of the KCl solution. In this case, it is 40 meq of KCl in 100 ml of dextrose 5% in water. So, each 100 ml of the solution contains 40 meq of KCl. Therefore, the rate should be set at 10 ml/hour, as 10 meq per hour is equal to 10 ml per hour.
