Q: A 1-year-old child weighing 26 lbs is prescribed amoxicillin at 40 mg/kg/day divided every 8 hours for 10 days. What is the total daily dose in mg? (1 kg = 2.2 lbs)

$\text{Total daily dose} = 40 \times (26/2.2) = 473 \text{ mg}$

Q: A 6-year-old child weighing 44 lbs needs ibuprofen for fever. The recommended dose is 10 mg/kg every 6-8 hours. What is the correct single dose in mg? (1 kg = 2.2 lbs)

$44 \div 2.2 = 20 \text{ kg}; 10 \times 20 = 200 \text{ mg}$

Q: A 70-year-old woman (IBW = 60 kg) with a serum creatinine (SCr) of 1.0 mg/dL is being evaluated for renal dosing. Using the Cockcroft-Gault equation for females, what is her estimated creatinine clearance (CrCl)? $\text{CrCl} = 0.85 \times \frac{(140 - \text{Age}) \times \text{IBW}}{72 \times \text{SCr}}$

$0.85 \times \frac{(140-70) \times 60}{72 \times 1.0} = 0.85 \times \frac{70 \times 60}{72} = 0.85 \times 58.33 = 49.6 \text{ mL/min}$

Accepted Answer

They often have multiple comorbidities and use multiple medications (polypharmacy).

Question 7

A 70-year-old woman (IBW = 60 kg) with a serum creatinine (SCr) of 1.0 mg/dL is being evaluated for renal dosing. Using the Cockcroft-Gault equation for females, what is her estimated creatinine clearance (CrCl)? $	ext{CrCl} = 0.85 	imes \frac{(140 - 	ext{Age}) 	imes 	ext{IBW}}{72 	imes 	ext{SCr}}$

Accepted Answer

$0.85 	imes \frac{(140-70) 	imes 60}{72 	imes 1.0} = 0.85 	imes \frac{70 	imes 60}{72} = 0.85 	imes 58.33 = 49.6 	ext{ mL/min}$
