Final answer:
To administer the prescribed dose of filgrastim for a 70 kg client, the nurse should give 1.2 mL of the medication every 12 hours, after rounding the exact calculation to the nearest tenth.
Step-by-step explanation:
To calculate the dosage of filgrastim a nurse should administer to a client who weighs 70 kg, we'll use the dosage formula prescribed.
The recommended dose is 5 mcg/kg every 12 hours. The conversion factor given is 300 mcg/mL for filgrastim. Calculation steps:
- Multiply the client's weight in kg by the dosage per kg: 70 kg × 5 mcg/kg = 350 mcg.
- Now, to get the volume in milliliters, divide the total mcg dose by the concentration of the vial (300 mcg/mL): 350 mcg / 300 mcg/mL.
- The calculation gives a dose of about 1.17 mL.
If rounding is required, the nurse should administer 1.2 mL.
