Question

A nurse is preparing to administer 40 mEq of potassium chloride in 45% sodium chloride (NaCl) 500 mL IV to infuse 10 mEq/hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

The nurse should set the IV pump to deliver 125 mL/hr.

Step-by-step explanation:

To calculate the mL/hr rate for the IV pump, we need to use the formula:

(mEq/hr) x (IV volume in mL) / (mEq of medication in the solution) = mL/hr

Plugging in the values, we have:

(10 mEq/hr) x (500 mL) / (40 mEq) = 125 mL/hr

Therefore, the nurse should set the IV pump to deliver 125 mL/hr.

Answer 2

To infuse 40 mEq of potassium chloride at a rate of 10 mEq/hr using a 500 mL solution, the nurse should set the IV pump to deliver 125 mL/hr.

Step-by-step explanation:

The question asks how to set an IV pump to deliver 40 mEq of potassium chloride (KCl) in 500 mL of solution to infuse at a rate of 10 mEq per hour. To calculate the rate in mL/hr, you need to determine how many mLs contain 10 mEq of KCl. With 40 mEq present in 500 mL, you can calculate the rate as follows:

(10 mEq) / (40 mEq) = x mL / (500 mL)

By cross-multiplying and solving for x, we have:

x = (10 mEq) × (500 mL) / (40 mEq)

x = (5000 mEq·mL) / (40 mEq)

x = 125 mL

Therefore, the nurse should set the IV pump to 125 mL/hr.
