A nurse is preparing to administer darbepoetin 0.45 mcg/kg subcutaneous once weekly to a client who weighs 198 lb. The amount available is Darbepoetin 300 mcg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.1"]
To calculate the dose of darbepoetin that the nurse should administer, we can follow these steps:
Convert the client's weight from pounds to kilograms:
198 lb ÷ 2.2 = 89.82 kg (rounded to two decimal places)
Calculate the dose of darbepoetin:
0.45 mcg/kg × 89.82 kg = 40.41 mcg
Determine the volume of darbepoetin needed using the available concentration:
40.41 mcg ÷ 300 mcg/mL = 0.1347 mL
Rounding to the nearest tenth, the nurse should administer 0.1 mL of darbepoetin subcutaneously once weekly.

Explanation
To calculate the amount of belimumab that the nurse should administer, we can use the following steps:
Convert the patient's weight from pounds to kilograms.
Multiply the patient's weight in kilograms by the dosage of belimumab (10 mg/kg) to find the total dosage required.
Determine the volume of the drug needed using the concentration of the available belimumab solution.
Given:
Patient's weight = 136 lb
Dosage of belimumab = 10 mg/kg
Available concentration of belimumab = 80 mg/mL
Let's calculate step by step:
Convert patient's weight from pounds to kilograms:
Patient's weight in kg = 136 lb × (1 kg / 2.2 lb) ≈ 61.8 kg
Calculate the total dosage required:
Total dosage = 10 mg/kg × 61.8 kg ≈ 618 mg
Determine the volume of the drug needed using the concentration of the available belimumab solution:
Volume of drug = Total dosage / Concentration of belimumab
Volume of drug = 618 mg / 80 mg/mL ≈ 7.7 mL
Rounding to the nearest whole number, the nurse should administer 8 mL of the belimumab.
Correct Answer is ["2.8"]
Explanation
Convert the patient's weight from pounds to kilograms:
154 lb ÷ 2.2 = 70 kg
Calculate the dose of pentamidine:
4 mg/kg × 70 kg = 280 mg
Determine the volume to be administered:
We have 100 mg/mL concentration of pentamidine.
280 mg ÷ 100 mg/mL = 2.8 mL
Therefore, the nurse should administer 2.8 mL of pentamidine to the client.
