The healthcare provider prescribes oral ibuprofen for a toddler who weighs 3333 pounds and has a temperature of 101.2∘F101.2^\circ\text{F} (38.4∘C38.4^\circ\text{C}). The prescribed dosage is 10 mg/kg10\text{ mg/kg} per dose. The available medication is an oral suspension labeled 100 mg/5 mL100\text{ mg}/5\text{ mL}. How many milliliters should the nurse administer for a single dose?

Record your answer to the nearest tenth. Do not include units in the answer.

Cevap: 7.5 mL

Cevap

7.5
To find the correct administration volume, the practical nurse must systematically process the data. First, the toddler's weight is converted to standard metric units by dividing by 2.22.2 (33 lbs÷2.2=15 kg33 \text{ lbs} \div 2.2 = 15\text{ kg}). Next, the weight is multiplied by the ordered weight-based dose to find the target milligrams (15 kg×10 mg/kg=150 mg15\text{ kg} \times 10\text{ mg/kg} = 150\text{ mg}). Finally, the nurse calculates the required volume using the supplied concentration: (150 mg÷100 mg)×5 mL=7.5 mL(150\text{ mg} \div 100\text{ mg}) \times 5\text{ mL} = 7.5\text{ mL}.

Adım Adım Çözüm

1
Convert the toddler'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}
Weight-based medication dosages must be calculated using kilograms to ensure safe administration limits.
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 prescription specifies a weight-based dose of 10 mg for every kilogram of body weight.
3
Calculate the administration volume using the available suspension concentration.
(150 mg÷100 mg)×5 mL=7.5 mL(150 \text{ mg} \div 100 \text{ mg}) \times 5 \text{ mL} = 7.5 \text{ mL}
Applying the desired over have formula determines the exact liquid volume needed to deliver the prescribed milligram dose.
