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

Correct Answer is ["2525"]
Explanation
To calculate the total intake, we'll add up the volumes of all fluids the client received during the past 9 hours:
Lactated Ringer's IV:
150 mL/hr × 9 hrs = 1350 mL
Cefazolin:
100 mL (intermittent bolus)
Packed RBCs:
250 mL +275 mL = 525 mL
IV bolus infusions:
2 × 250 mL = 500 mL
Ranitidine:
50 mL (intermittent bolus)
Total intake:
1350 mL + 100 mL + 525 mL + 500 mL + 50 mL = 2520 mL
Correct Answer is ["12.8"]
Explanation
To calculate the infusion rate, we'll follow these steps:
Convert patient weight to kg:
176 lbs ÷ 2.2 lbs/kg = 80 kg
Calculate desired heparin dose:
16 units/kg/hr × 80 kg = 1280 units/hr
Determine infusion rate in mL/hr:
(1280 units/hr) / (50000 units/500 mL) = 12.8 mL/hr
