Solution

Solution Steps

To determine how many mL the nurse should administer per dose, we need to divide the required dose of penicillin G benzathine (1,200,000 units) by the concentration of the available solution (600,000 units/mL). This will give us the volume in mL that needs to be administered.

Step 1: Determine the Required Dose and Concentration

The nurse needs to administer a dose of penicillin G benzathine of $1,200,000$ units. The available solution has a concentration of $600,000$ units/mL.

Step 2: Calculate the Volume to Administer

To find the volume in mL that should be administered, divide the required dose by the concentration of the solution:

\[ \text{Volume to administer} = \frac{1,200,000 \, \text{units}}{600,000 \, \text{units/mL}} = 2 \, \text{mL} \]
