The doctor orders medication S 2.5 mg/kg/day in two divided doses. Medication S is supplied 40 mg/mL. The patient weighs 121 lbs. What will 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.)
The Correct Answer is ["1.7"]
To calculate the medication dosage, we'll follow these steps:
Convert patient weight to kilograms:
121 lbs ÷ 2.2 lbs/kg = 55 kg
Determine the total daily dosage:
2.5 mg/kg/day × 55 kg = 137.5 mg/day
Calculate the dosage per dose:
137.5mg/day ÷ 2 doses = 68.75 mg/dose
Determine the volume to be administered:
68.75 mg ÷ 40 mg/mL = 1.7 mL

Determine the required volume:
500 mg ÷ 125 mg/5 mL = 20 mL

Explanation
To calculate the total fluid intake, we'll need to convert all the volumes to a common unit (mL).
Juice:
½ cup = 120 mL (assuming a standard 8-ounce cup)
Gelatin:
3 oz = 90 mL (1 ounce is approximately 30 mL)
Ice pop:
1 oz = 30 mL
Ginger ale:
20 mL
Total intake:
120 mL + 90 mL + 30 mL + 20 mL = 260 mL
