Zorluk: OrtaPharmacological Therapies

A toddler weighing 35.235.2 lb is prescribed oral acetaminophen 1515 mg/kg every 44 hours as needed for fever. The medication available is an oral suspension with a concentration of 160160 mg/55 mL. How many milliliters should the practical nurse administer for one dose? (Record answer to the nearest tenth. Do not include units in answer.)

Cevap: 7.5 mL

Cevap

7.5
The calculation requires three clinical math steps: first converting the client's weight to kilograms (35.2÷2.2=1635.2 \div 2.2 = 16 kg), determining the weight-based dose (16×15=24016 \times 15 = 240 mg), and then calculating the liquid volume using the available concentration of 160160 mg per 55 mL (240160×5=7.5\frac{240}{160} \times 5 = 7.5 mL). The correct final amount to administer is 7.57.5 mL.

Adım Adım Çözüm

1
Convert the child's weight from pounds (lb) to kilograms (kg).
1616 kg
The medication dosage is prescribed in mg/kg, requiring the client's weight to be converted using the factor 11 kg = 2.22.2 lb (35.2÷2.2=1635.2 \div 2.2 = 16).
2
Calculate the total required dose in milligrams (mg).
240240 mg
Multiply the weight in kilograms by the prescribed dosage amount (16 kg×15 mg/kg=240 mg16 \text{ kg} \times 15 \text{ mg/kg} = 240 \text{ mg}).
3
Calculate the volume of liquid to administer in milliliters (mL).
7.57.5 mL
Use the formula: (Desired / Have) × Quantity. Here, (240 mg160 mg\frac{240 \text{ mg}}{160 \text{ mg}}) × 5 mL=1.5×5 mL=7.5 mL5 \text{ mL} = 1.5 \times 5 \text{ mL} = 7.5 \text{ mL}.
