A primary healthcare provider has prescribed 1.8 mg/kg of brentuximab for a client who has Hodgkin lymphoma and weighs 60 kg. The nurse has on hand 50 mg per 10 mL.
How many mL of medication should the nurse administer to the client?
21.6 mL
26.4 mL
54 mL
64.8 mL
The Correct Answer is A
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 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 B
Explanation
We can use the formula for calculating infusion time:. Infusion time = Total volume / Infusion rate.
First, we need to convert the volume of the fluid from liters to milliliters:.
0.75 L = 750 mL.
Next, we can plug in the values we have:. Infusion time = 750 mL / 120 mL/hr.
Infusion time = 6.25 hours.
Since the infusion was started at 9:00 a.m., we can add 6.25 hours to determine when the infusion will be completed:.
9:00 a.m. + 6.25 hours = 3:15 p.m..
Therefore, the infusion will be completed at 3:15 p.m.
