Explanation
Dose required: 40 mg
Concentration: 125 mg/2 mL = 62.5 mg/mL
Volume to administer: 40 mg ÷ 62.5 mg/mL = 0.64 mL
Correct Answer is ["0.42"]
Explanation
1. Determine the concentration of the reconstituted solution:
- The vial contains 0.3 mg of interferon beta-1b.
- It's reconstituted with 2 mL of sterile water.
- Concentration: 0.3 mg / 2 mL = 0.15 mg/mL
2. Calculate the volume to administer:
- The prescribed dose is 0.0625 mg.
- Concentration: 0.15 mg/mL
- Volume: (Desired Dose) / (Concentration) = 0.0625 mg / 0.15 mg/mL = 0.416666... mL
3. Round to the nearest hundredth:
- 0.416666... mL rounded to the nearest hundredth is 0.42 mL.
Therefore, the nurse should administer 0.42 mL.
