A nurse is preparing to administer filgrastim 250 mcg subcutaneous. How many mg should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.25"]
To convert micrograms to milligrams, divide by 1000: 250 mcg / 1000 = 0.25 mg. Round to the nearest hundredth: 0.25 mg. Therefore, the nurse should administer 0.25 mg of filgrastim.

Correct Answer is ["1"]
Explanation
To answer this question, you need to convert the dosage of fentanyl from micrograms (mcg) to milligrams (mg). One milligram is equal to 1000 micrograms, so 50 mcg is equal to 0.05 mg. Then, you need to use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity. In this case, D is 0.05 mg, H is 0.05 mg/mL, and Q is the volume in milliliters. Plugging these values into the formula, you get:
0.05 mg / 0.05 mg/mL x Q
Q = 1 mL
Therefore, the nurse should administer 1 mL of fentanyl per dose.
Correct Answer is ["286"]
Explanation
To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:
mL = (mg/kg x kg) / (mg/mL)
The client's weight in kilograms is:
126 lb / 2.2 lb/kg = 57.27 kg
The concentration of foscarnet in mg/mL is:
6,000 mg / 500 mL = 12 mg/mL
Plugging these values into the formula, we get:
mL = (60 mg/kg x 57.27 kg) / (12 mg/mL)
mL = (3,436.2 mg) / (12 mg/mL)
mL = 286.35 mL
Therefore, the nurse should administer 286 mL of foscarnet.
