Answer
0.2 mL of compazine solution is administered to the patient.
Work Step by Step
1. Convert the mass to grams:
- 1 g = 1000 mg
$$5 \space mg \times \frac{1 \space g}{1000 \space mg} = 0.005 \space g$$
2. Find the volume:
$2.5\%$ (m/v) $ compazine $ solution : $$ 2.5 \space g \space compazine = 100 \space mL \space solution$$
$$0.005 \space g \space compazine \times \frac{100 \space mL \space solution}{2.5 \space g \space compazine} = 0.2 \space mL \space solution$$
