Final answer:
Infants are at risk for drug toxicity due to decreased liver enzymes, reduced kidney perfusion, and reduced percentage of body water.
Step-by-step explanation:
Infants are at risk for drug toxicity due to the following factors:
- Decreased liver enzymes: Infants have lower levels of liver enzymes, which play a crucial role in metabolizing drugs. This can lead to a slower clearance of drugs from the body and an increased risk of toxicity.
- Reduced kidney perfusion: The kidneys are responsible for filtering drugs and removing them from the body. In infants, reduced kidney perfusion can affect the elimination of drugs, increasing the risk of toxicity.
- Reduced percentage of body water: Infants have a higher proportion of body water compared to adults. This means that the concentration of drugs in their body can be higher, potentially leading to toxicity.
