Answer 1

The dosage of phenytoin 100 mg per day is safe for a child weighing 20 kg, as it is within the recommended range of 4-8 mg/kg/day. The statement, this dosage is safe for this child is true.

Step-by-step explanation:

The question asks whether a prescribed dose of phenytoin 100 mg per day is safe for a child who weighs 20 kg, given that the recommended dosage is 4-8 mg/kg/day.

To determine if this dosage is safe, we can calculate the maximum recommended daily dosage for the child by multiplying the child's weight by the upper limit of the recommended dosage: 20 kg × 8 mg/kg = 160 mg/day.

Since the prescribed dosage is 100 mg/day, which is within the safe range of 80-160 mg/day for a child of this weight, we can conclude that the dosage is safe.
