A school-aged child who weighs 33 lbs33\text{ lbs} requires antipyretic therapy. The healthcare provider prescribes oral ibuprofen at 10 mg/kg/dose10\text{ mg/kg/dose} every 6 hours6\text{ hours}. The pharmacy dispenses an ibuprofen oral suspension with a concentration of 100 mg100\text{ mg} per 5 mL5\text{ mL}. Calculate the volume, in milliliters (mL\text{mL}), the practical nurse should administer for a single dose. Record the answer to the nearest tenth. Do not include units in your answer.

Cevap: 7.5 mL

Cevap

7.5
To determine the correct volume, the nurse must first convert the child's weight to kilograms (33 lbs÷2.2=15 kg33\text{ lbs} \div 2.2 = 15\text{ kg}). Next, the weight is multiplied by the prescribed dosage parameter (15 kg×10 mg/kg=150 mg15\text{ kg} \times 10\text{ mg/kg} = 150\text{ mg}). Finally, using the desired-over-have method, the liquid volume is calculated: (150 mg÷100 mg)×5 mL=7.5 mL(150\text{ mg} \div 100\text{ mg}) \times 5\text{ mL} = 7.5\text{ mL}. The value is exactly 7.57.5, so it meets the requirement of being recorded to the nearest tenth.

Adım Adım Çözüm

1
Convert the patient's weight from pounds to kilograms.
33 lbs÷2.2 lbs/kg=15 kg33\text{ lbs} \div 2.2\text{ lbs/kg} = 15\text{ kg}
Standard pediatric medication dosages are calculated based on weight in kilograms.
2
Calculate the total required dose in milligrams.
15 kg×10 mg/kg=150 mg15\text{ kg} \times 10\text{ mg/kg} = 150\text{ mg}
The prescribed dose must be multiplied by the patient's body weight to find the individualized dose.
3
Calculate the final liquid volume to administer based on the pharmacy's concentration.
150 mg100 mg×5 mL=7.5 mL\frac{150\text{ mg}}{100\text{ mg}} \times 5\text{ mL} = 7.5\text{ mL}
The ordered milligram dose must be converted into the administrable liquid volume.
