Why is borrowing medication from one child to give to another considered problematic?

Borrowing medication from one child to give to another is problematic primarily because it can lead to incorrect dosages being administered. The dosage of medication is specifically tailored to each individual based on various factors such as their age, weight, medical history, and specific health conditions. When medications are shared, the receiving child may not receive the appropriate dosage, which can lead to underdosing or overdosing.

Using the wrong dosage can have serious consequences, including ineffective treatment or adverse effects. Sharing medication does not account for these crucial individual-specific needs and can disrupt the expected therapeutic outcome. Thus, this practice is a violation of safe medication administration protocols and poses significant risks to the health and safety of children.

The other options, while relevant to medication safety, do not capture the immediate risks associated with dosage errors specifically stemming from borrowing medications. Misdiagnoses, allergic reactions, and legal issues may arise in different contexts, but the concern of incorrect dosages directly illustrates the risks of such actions.
