In a pediatric clinic, medical assistants use a specific strategy to calculate medication dosages based on a child's weight. If the standard dosage for a certain medication is 5 milliliters (ml) for every 25 pounds (lb) of weight, which proportion correctly represents the setup to find the dosage ($a$) for a child weighing 45 lb?

A medical assistant in a pediatric clinic needs to calculate the dosage of acetaminophen for a child weighing 60 pounds, based on a standard dosage of 5 milliliters (ml) for every 25 pounds (lb). Arrange the following steps in the correct order to solve this problem using a proportion strategy.

A medical assistant is using a proportion to calculate a pediatric dose of acetaminophen. Based on the clinic's protocol for a child weighing ${}60$ pounds, match each element of the proportion $\frac{5}{25} = \frac{a}{60}$ to its corresponding clinical meaning.

True or False: According to the recommended strategy for solving the dosage proportion $\frac{5}{25} = \frac{a}{60}$, the first step is to simplify the fraction $\frac{5}{25}$ to $\frac{1}{5}$.

Initial Step in Dosage Proportion Calculation

In a pediatric clinic, medical assistants use a standard ratio of 5 ml of acetaminophen for every 25 pounds of a child's weight to calculate dosage. When simplifying this ratio to find the unit rate, a child is prescribed 1 ml of acetaminophen for every ____ pounds of body weight.
