A nurse is preparing to administer epoetin alfa 7,000 units subcutaneous once a week to a client. Available is epoetin alfa 20,000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
To determine the volume of epoetin alfa to administer, use the following formula:Volume (mL)=Desired dose (units)Concentration (units/mL)\text{Volume (mL)} = \frac{\text{Desired dose (units)}}{\text{Concentration (units/mL)}}Volume (mL)=Concentration (units/mL)Desired dose (units)
Given:
- Desired dose = 7,000 units
- Concentration = 20,000 units/mL
Calculate the volume:Volume (mL)=7,000 units20,000 units/mL=0.35 mL\text{Volume (mL)} = \frac{7,000 \text{ units}}{20,000 \text{ units/mL}} = 0.35 \text{ mL}Volume (mL)=20,000 units/mL7,000 units=0.35 mL
So, the nurse should administer 0.35 mL of epoetin alfa.
Correct answer: 0.35
