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 ["2 "]

Explanation

Given:

Desired dose of levothyroxine: 0.05 mg
Available strength of levothyroxine tablets: 25 mcg

First, convert the desired dose from milligrams to micrograms:

0.05 mg = 50 mcg

Number of tablets = Desired dose / Strength per tablet

Number of tablets = 50 mcg / 25 mcg/tablet Number of tablets = 2 tablets

So, the nurse should plan to administer 2 tablets of levothyroxine.

Correct Answer is ["3"]

Explanation

Given:

Desired dose of bumetanide: 1.5 mg
Available strength of bumetanide tablets: 0.5 mg

First, find out how many tablets are needed:

Number of tablets = Desired dose / Strength per tablet

Number of tablets = 1.5 mg / 0.5 mg/tablet Number of tablets = 3 tablets

So, the nurse should administer 3 tablets of bumetanide.
