Explanation
Understanding the Problem We are given that a child requires a single total daily dose of 7.0 mg per kg of body weight of drug A. The child's weight is 8.0 kg. We need to find the total daily dose of drug A for the child.
Calculating the Total Dose To find the total daily dose, we need to multiply the dosage rate (7.0 mg/kg) by the child's weight (8.0 kg).
Performing the Calculation The total daily dose is calculated as follows: Total daily dose = Dosage rate × Child’s weight = 7.0 mg/kg × 8.0 kg Total daily dose = 56.0 mg
Final Answer Therefore, the total daily dose of drug A that the child should receive is 56.0 mg.
