A nurse is preparing to administer chlorpromazine 0.55 mg/kg IM every 6 hr to a child who weighs 44 lb. Available is chlorpromazine 25 mg/mL injection. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.4 "]

Given:

Desired dose of chlorpromazine: 0.55 mg/kg every 6 hours
Child's weight: 44 lb
Available strength of chlorpromazine injection: 25 mg/mL

First, convert the child's weight from pounds to kilograms:

44 lb ÷ 2.20462 = 20 kg

Now, let's calculate the desired dose of chlorpromazine:

Desired dose = Dosage per kg × Weight Desired dose = 0.55 mg/kg × 20 kg Desired dose = 11 mg

Now, let's find out how many milliliters of chlorpromazine correspond to this dose: Volume (mL) = Desired dose / Concentration

Volume (mL) = 11 mg / 25 mg/mL Volume (mL) ≈ 0.44 mL

So, the nurse should administer approximately 0.4 mL of chlorpromazine per dose.

Correct Answer is ["0.63 "]

Explanation

Given:

Desired dose of testosterone cypionate: 125 mg
Available strength of testosterone cypionate injection: 200 mg/mL

First, find out how many milliliters of testosterone cypionate correspond to the desired dose:

Volume (mL) = Desired dose / Concentration

Volume (mL) = 125 mg / 200 mg/mL Volume (mL) = 0.625 mL

Rounded off to the nearest hundredth= 0.63ml

So, the nurse should administer approximately 0.63 mL of testosterone cypionate per dose.

Correct Answer is ["20 "]

Explanation

Given:

Desired dose of megestrol: 800 mg
Available strength of megestrol suspension: 40 mg/mL

First, find out how many milliliters of megestrol suspension correspond to the desired dose: Volume (mL) = Desired dose / Concentration

Volume (mL) = 800 mg / 40 mg/mL Volume (mL) = 20 mL

So, the nurse should administer 20 mL of megestrol suspension.
