Order:cyanocobalamin 0.2mg IV monthly Available:1000mcg/mL How many mL will you give?

1. Convert the ordered dose from mg to mcg:
0.2 \, \text{mg} = 0.2 \times 1000 \, \text{mcg} = 200 \, \text{mcg}

2. Use the concentration to find the volume required:
\text{Volume} = \frac{\text{Dose}}{\text{Concentration}} = \frac{200 \, \text{mcg}}{1000 \, \text{mcg/mL}} = 0.2 \, \text{mL}

Answer: 0.2 \, \text{mL}
