Final answer:
The prescribed amount of diphenhydramine for a pediatric patient with an acute allergic reaction would be determined based on the child's weight and other factors, such as the severity of the reaction.
Step-by-step explanation:
In the case of a pediatric patient with an acute allergic reaction, the prescribed amount of diphenhydramine would not simply be scaled down based on the patient's age. The dosage for children is typically calculated based on the child's weight, rather than age. To determine the appropriate dose for the pediatric patient, the doctor would need to consider the child's weight and other factors, such as the severity of the reaction.
It is important to consult a healthcare professional for proper dosing instructions and to ensure the safety and effectiveness of the medication for pediatric patients.
