What should a nurse monitor for when administering antihistamines to young children?

When administering antihistamines to young children, it is crucial for the nurse to monitor safety and potential side effects closely. Antihistamines can have varying effects on children, and they may be more susceptible to the sedative effects of these medications. Side effects may include drowsiness, agitation, irritability, and in some cases, paradoxical reactions that lead to increased excitement instead of sedation. Monitoring for these side effects is vital to ensure the child's safety and to determine if the medication is having the intended effect without causing harm.

In the context of the other responses, increased appetite, withdrawn behavior, and heightened energy, while they may be observed in some children, are not primary concerns directly associated with antihistamine administration. Safety monitoring encompasses a broader evaluation of the child's overall reaction to the medication, ensuring that any adverse effects are promptly addressed.
