- C. My baby can't handle a high dose of Tylenol because her liver may be damaged.'
- D. My child's dose of Tylenol should be based on her weight or age.'
Correct Answer: B
Rationale: A child's dose is never based on an adult's dose. However, on rare occasions a child's dose might be higher than normal if a critical concentration cannot be reached with a smaller dose and a higher dose would not be harmful. Benefits from the increased dosage would have to outweigh the risk for adverse or toxic effects. A child's organs may not be mature enough to handle drugs, causing drug metabolism to be altered. A child's dosages are determined by the age, weight, or body surface.
