A nurse will administer Zofran (ondansetron) 0.15 mg/kg over 15 minutes. The patient weighs 176 lb. The nurse receives the medication from the pharmacy mixed in 50 mL normal saline...
How should the nurse set the IV pump to deliver the correct dose?
100 mL/hr
150 mL/hr
200 mL/hr
400 mL/hr
The Correct Answer is C
The patient is ordered to receive 0.15 mg/kg of Zofran over 15 minutes. The patient weighs 176 lb, which is equivalent to 80 kg. To calculate the total amount of Zofran the patient should receive, multiply the weight by the dosage:
80 kg x 0.15 mg/kg = 12 mg
The Zofran arrives from the pharmacy mixed in 50 mL of normal saline, which means there is 12 mg of Zofran in 50 mL of solution. To calculate how many milliliters per hour the nurse should set the IV pump, we can use the following formula:
50 mL / 0.25 hour = X mL per hour X = 200 mL per hour
Therefore, the nurse should set the IV pump to deliver 200 mL of Zofran per hour to the patient.
