A practical nurse is caring for an adult client who weighs $143\text{ lb}$ and is prescribed cyclosporine oral solution. The prescribed dosage is $8\text{ mg/kg/day}$ divided into two equal doses. The pharmacy dispenses cyclosporine oral solution $100\text{ mg/mL}$ . How many mL should the nurse administer for one dose?

Record your answer using one decimal place. Do not include units in your answer.

Cevap: 2.6 mL

Cevap

The practical nurse should administer 2.6 mL per dose.

To determine the correct volume, the client's weight must first be converted to kilograms (

143\text{ lb} \div 2.2 = 65\text{ kg}

). The total daily dose is calculated by multiplying the weight by the prescribed rate (

65\text{ kg} \times 8\text{ mg/kg} = 520\text{ mg/day}

). Because the medication is divided into two equal doses, the single dose is

260\text{ mg}

(

520\text{ mg} \div 2

). Finally, using the available concentration of

100\text{ mg/mL}

, the required volume is

2.6\text{ mL}

(

260\text{ mg} \div 100\text{ mg/mL}

Adım Adım Çözüm

Convert pounds to kilograms.

143\text{ lb} \div 2.2 = 65\text{ kg}

The prescribed dose is weight-based in kg, so the client's weight must first be converted.

Calculate the total daily dose.

65\text{ kg} \times 8\text{ mg/kg} = 520\text{ mg/day}

To find the total amount of medication required for a 24-hour period.

Determine the single dose amount.

520\text{ mg} \div 2\text{ doses} = 260\text{ mg/dose}

The prescription states the daily dose is divided into two equal doses.

Calculate the liquid volume to administer.

(

260\text{ mg} \div 100\text{ mg}) \times 1\text{ mL} = 2.6\text{ mL}

To determine how many mL provide the required single dose of 260 mg using the available concentration.
