A nurse is preparing to administer calcitonin & units/kg IM to a client who weighs 130 lb. Available is calcitonin 200 units/mL for injection.
How many mL should the nurse administer? (Round the answer to the nearest tenth.
Use a leading zero if it applies.
Do not use a trailing zero.). mL.
The Correct Answer is ["8"]
Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is ordered in units/kg. There are approximately 2.2 lb/kg, so 130 lb ÷ 2.2 lb/kg = 59.1 kg. The doctor ordered calcitonin at a dosage of & units/kg, so we multiply the client’s weight in kg by the dosage: 59.1 kg × & units/kg = & units. The medication is available at a concentration of 200 units/mL, so we divide the total units needed by the units per mL: & units ÷ 200 units/mL = & mL.
So, the correct answer is 8 mL.

Correct Answer is ["48"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms since the medication dosage is prescribed in mg/kg. Given that 1 kg is approximately 2.2 lb, the conversion is:
210 lb ÷ 2.2 = 95.45 kg (rounded to the nearest hundredth).
Step 2 is to calculate the total amount of medication needed using the formula:
Dose (mg/kg) × Weight (kg) = Total medication needed (mg)
5 mg/kg × 95.45 kg = 477.27 mg (rounded to the nearest hundredth).
Step 3 is to calculate the volume to administer using the formula:
Total medication needed (mg) ÷ Concentration (mg/mL) = Volume to administer (mL)
477.27 mg ÷ 10 mg/mL = 47.73 mL
Rounding off to the nearest whole number, the nurse should administer 48 mL of gentamicin.
Correct Answer is ["0.5"]
Explanation
Step 1 is to determine the amount of medication needed. This is done by dividing the desired dose by the available dose. So, we have 12.5 mg ÷ 25 mg/mL = 0.5 mL.
So, the correct answer is 0.5 mL.
