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 ["3.5"]
Explanation
-
Convert the client's weight from pounds to kilograms:
- 154 lb ÷ 2.2 lb/kg = 70 kg
-
Calculate the total dose required:
- 0.25 mg/kg × 70 kg = 17.5 mg
-
Determine the volume to administer:
- Given concentration: 5 mg/mL
- 17.5 mg ÷ 5 mg/mL = 3.5 mL
-
Rounding to the nearest tenth:
- The answer remains 3.5 mL
So the nurse should administer 3.5 mL of diltiazem IV injection.
which is 17.5 mg / 5 mg/mL = 3.5 mL. Rounding to the nearest tenth, the nurse should administer 3.5 mL of diltiazem IV injection.
Correct Answer is ["1.9"]
Explanation
To calculate the dose of dexamethasone, we need to convert the client's weight from pounds to kilograms. One pound is equal to 0.454 kg, so 132 lb is equal to 132 x 0.454 = 59.928 kg. The prescribed dose is 0.5 mg/kg/day, so the daily dose is 0.5 x 59.928 = 29.964 mg. This dose is divided equally every 6 hours, so the dose per administration is 29.964 / 4 = 7.491 mg. The concentration of the drug is 4 mg/mL, so the volume per administration is 7.491 / 4 = 1.873 mL. Rounded to the nearest tenth, the nurse should administer 1.9 mL per dose.
