To determine how many milliliters to administer, you can use the formula:
\[
\text{Volume to administer (mL)} = \frac{\text{Ordered dose (mg)}}{\text{Concentration (mg/mL)}}
\]
In this case:
- Ordered dose = 75 mg
- Concentration = 50 mg/mL
Using the formula:
\[
\text{Volume to administer} = \frac{75 \text{ mg}}{50 \text{ mg/mL}} = 1.5 \text{ mL}
\]
So, you would administer **1.5 mL** of Vistaril.
\[
\text{Volume to administer (mL)} = \frac{\text{Ordered dose (mg)}}{\text{Concentration (mg/mL)}}
\]
In this case:
- Ordered dose = 75 mg
- Concentration = 50 mg/mL
Using the formula:
\[
\text{Volume to administer} = \frac{75 \text{ mg}}{50 \text{ mg/mL}} = 1.5 \text{ mL}
\]
So, you would administer **1.5 mL** of Vistaril.
