Pharmacy Technician Certification Board Practice Exam Practice Question

Correct Answer: D

Rationale: To determine the volume of morphine sulfate needed for a 25 mg order, first, calculate how many milliliters are required using the concentration of 5 mg/mL.

Using the formula:
\[ \text{Volume (mL)} = \frac{\text{Desired dose (mg)}}{\text{Concentration (mg/mL)}} \]
\[ \text{Volume} = \frac{25 \text{ mg}}{5 \text{ mg/mL}} = 5 \text{ mL} \]

Option A (1 mL) is insufficient for the required dose. Option B (2 mL) also falls short, providing only 10 mg. Option C (3 mL) yields just 15 mg, which is still inadequate. Only option D (5 mL) meets the requirement of 25 mg, making it the correct choice.
