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 B
Explanation
The amount of solution the nurse should withdraw from the vial can be calculated using the following formula:
Amount of solution = Amount of medication needed / Concentration of medication in the solution.
In this case, the amount of medication needed is 17.1 mg and the concentration of medication in the solution is 3 mg/mL. Substituting these values into the formula, we get:
Amount of solution = 17.1 mg / 3 mg/mL = 5.7 mL
Therefore, the answer is B. The nurse should withdraw 5.7 mL of solution from the vial.
Correct Answer is A
Explanation
To calculate the total amount of heparin, we need to multiply the infusion rate by the time and then by the concentration of heparin in the IV bag. From 9:00 a.m. to 11:00 a.m., the infusion rate was 12 mL/hr, so the amount of heparin infused in this period was 12 mL/hr x 2 hours x 100 units/mL = 2400 units.
From 11:00 a.m. to 2:00 p.m., the infusion rate was 10 mL/hr, so the amount of heparin infused in this period was 10 mL/hr x 3 hours x 100 units/mL = 3000 units. The total amount of heparin infused from 9:00 a.m. to 2:00 p.m. was 2400 units + 3000 units = 5400 units.
