Answer:

Some medications, particularly for children may be prescribed according to the person's body weight (kg) or body surface area (m²). Simply multiply the dose by the weight to determine the dose required which may then be placed in other formula.

Answer:

Calculate the dose of amoxicillin suspension in mLs for otitis media for a 1-yr-old child weighing 22 lb. The dose required is 40 mg/kg/day divided BID and the suspension comes in a concentration of 400 mg/5 mL.

Step 1. Convert pounds to kg: 22 lb × 1 kg/2.2 lb = 10 kg

Step 2. Calculate the dose in mg: 10 kg × 40 mg/kg/day = 400 mg/day

Step 3. Divide the dose by the frequency: 400 mg/day ÷ 2 (BID) = 200 mg/dose BID

Step 4. Convert the mg dose to mL: 200 mg/dose ÷ 400 mg/5 mL = 2.5 mL BID

Calculate the dose of ceftriaxone in mLs for meningitis for a 5-yr-old weighing 18 kg. The dose required is 100 mg/kg/day given IV once daily and the drug comes prediluted in a concentration of 40 mg/mL.

Step 1. Calculate the dose in mg: 18 kg × 100 mg/kg/day = 1800 mg/day

Step 2. Divide the dose by the frequency: 1800 mg/day ÷ 1 (daily) = 1800 mg/dose

Step 3. Convert the mg dose to mL: 1800 mg/dose ÷ 40 mg/mL = 45 mL once daily

Calculate the dose of vincristine in mLs for a 4-yr-old with leukemia weighing 37 lb and is 97 cm tall. The dose required in 2 mg/m2 and the drug comes in 1 mg/mL concentration.

Step 1. Convert pounds to kg: 37 lb × 1 kg/2.2 lb = 16.8 kg

Step 2. Calculate BSA: √16.8 kg × 97 cm/3600 = 0.67 m2

Step 3. Calculate the dose in mg: 2 mg/m2 × 0.67 m2 = 1.34 mg

Step 4. Calculate the dose in mL: 1.34 mg ÷ 1 mg/mL = 1.34 mL
