Solution Steps

Step 1: Determine the concentration of heparin in the vial

The vial contains 2,000 units of heparin in 2 mL. Therefore, the concentration is: \[ \text{Concentration} = \frac{2000 \text{ units}}{2 \text{ mL}} = 1000 \text{ units/mL} \]

Step 2: Calculate the volume needed for the prescribed dose

The physician orders 900 units of heparin. Using the concentration calculated in Step 1: \[ \text{Volume needed} = \frac{\text{Prescribed dose}}{\text{Concentration}} = \frac{900 \text{ units}}{1000 \text{ units/mL}} = 0.9 \text{ mL} \]

Final Answer

\[ 0.9 \text{ mL} \]
