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.

Correct Answer is B
Explanation
This choice is correct because it is the result of dividing the ordered dose (0.25 mg) by the strength of the tablet (250 mcg or 0.25 mg). The formula for calculating the number of tablets to be given is:
Tablets = Dose/ Strength
Therefore, the number of tablets to be given is:
Tablets = 0.25 mg/250 mcg = 0.25 mg/0.25 mg = 1
Correct Answer is ["48"]
Explanation
To calculate the amount of gentamicin the nurse should administer in milliliters (mL) for a client who weighs 210 lb, we can use the following steps:
Given:
Client's weight: 210 lb
Gentamicin dose: 5 mg/kg
Available concentration: 10 mg/mL
Step 1: Convert the client's weight from pounds (lb) to kilograms (kg)
Client's weight in kg = Client's weight in lb / 2.2
Client's weight in kg = 210 lb / 2.2
Client's weight in kg ≈ 95.45 kg
Step 2: Calculate the total dose of gentamicin required
Total dose = Client's weight in kg × Gentamicin dose
Total dose = 95.45 kg × 5 mg/kg
Total dose = 477.25 mg
Step 3: Calculate the volume of gentamicin to be administered in mL
Volume = Total dose / Concentration
Volume = 477.25 mg / 10 mg/mL
Volume ≈ 47.725 mL
Rounding to the nearest whole number:
Volume ≈ 48 mL
Therefore, the nurse should administer approximately 48 mL of gentamicin via intermittent IV bolus to the client who weighs 210 lb.
