-Step 1: Define the amount of diazepam to be administered and the concentration of the available diazepam injection. We know that the diazepam dose is 7.5 mg and the diazepam concentration is 5 mg/mL.
-Step 2: Calculate the volume of diazepam injection to be administered. The calculation is 7.5 mg (diazepam dose) ÷ 5 mg/mL (diazepam concentration) = 1.5 mL.
-Step 3: Round the result to the nearest tenth. The rounded result is 1.5 mL.

Step 1: The dose to be administered is50 mg of chlorpromazine.
