Practice Question

A nurse is preparing to administer calcitonin 8 units/kg IM to a client who weighs 165 lb. Available is 200 units/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use leading zero if it applies. Do not use a trailing zero.)

Answer Choices:

A. 3 ✓ Correct Answer

Correct Answer:

Rationale:

Step-by-step calculation:

Formula:

Volume (mL) = [Dose (units/kg) × Weight (kg)] ÷ Concentration (units/mL)

Step 1: Convert weight from pounds to kilograms

165 lb ÷ 2.2 = 75 kg

Step 2: Calculate total dose in units

8 units/kg × 75 kg = 600 units

Step 3: Plug into the volume formula

600 units ÷ 200 units/mL = 3 mL

Step 4: Round to the nearest whole number

3 mL is already a whole number

✅ Final Answer: 3 mL

Educational Insight:

Calcitonin is often used to treat conditions like hypercalcemia and osteoporosis. Since it is a weight-based medication, it's essential to convert pounds to kilograms accurately before calculating dosage. This ensures safe and therapeutic administration. Administer IM injections into a large muscle, and rotate sites to reduce irritation.
