Question

a nurse is preparing to administer potassium gluconate 2 meq/kg/day po divided equally every 12 hr to a child who weighs 50 lb. how many meq should the nurse administer per dose? (round the answer to the nearest tenth. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Convert pounds to kg

$50\ \text{lb} \times \frac{1\ \text{kg}}{2.2\ \text{lb}} \approx 22.727\ \text{kg}$

Step2: Calculate daily dose

$2\ \text{mEq/kg/day} \times 22.727\ \text{kg} \approx 45.454\ \text{mEq/day}$

Step3: Find per dose amount

$\frac{45.454\ \text{mEq/day}}{2\ \text{doses/day}} \approx 22.7\ \text{mEq}$

Answer:

22.7
