Answer to Question 1
ANS: A
The proper index of renal function in older adults is creatinine clearance, which indicates renal function in older patients whose organs are undergoing age-related deterioration. Sodium and potassium levels are not indicative of renal function. Serum creatinine levels do not reflect kidney function in older adults because lean muscle mass, which is the source of creatinine in serum, declines and may be low even with reduced kidney function.
Answer to Question 2
ANS: A
This formula helps determine an approximate first dose for a child that is extrapolated from an adult dose; subsequent doses should be adjusted based on clinical outcome and serum plasma levels. The formula accounts only for differences in weight and not for differences in pharmacokinetic factors. The formula helps determine an effective dose but cannot account for unusual side effects that may occur in children. It may not be effective for all ages because of rapid changes in pharmacokinetics.
