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.

Correct Answer is A
Explanation
To calculate the dose of brentuximab in mg that the client should receive, we need to multiply the weight of the client in kg by the prescribed dose of 1.8 mg/kg:.
Dose (in mg) = Weight (in kg) x Dose (in mg/kg).
Dose (in mg) = 60 kg x 1.8 mg/kg. Dose (in mg) = 108 mg.
Now we need to calculate the volume of medication to administer. Since the medication available is 50 mg per 10 mL, we can use proportion to calculate the volume:.
50 mg is to 10 mL as 108 mg is to X mL. 50/10 = 108/X.
Cross-multiplying, we get:. 50X = 108 x 10.
X = (108 x 10)/50. X = 21.6 mL.
Therefore, the nurse should administer 21.6 mL of brentuximab to the client.
Correct Answer is C
Explanation
The patient is ordered to receive 5 mg of Lopressor over 60 seconds, which is equivalent to 1 minute. The concentration of Lopressor is 1 mg/1 mL, which means there is 1 mg of Lopressor in 1 mL of solution. To calculate how many milliliters per minute the nurse should administer, we can use the following formula:
5 mg / 1 mg per 1 mL = X mL X = 5 mL per minute.
