Question

solve the dosage by weight conversion problem.
the nurse is to administer the recommended dose of a drug, 4 milligrams per kilogram every 6 hours. the child weighs 42 pounds.
a) what is the weight in kilograms?
b) what is the daily dose?
c) what is the individual dose?
a) the childs weight in kilograms is 19.05.
(round to the nearest hundredth as needed.)
b) the daily dose is ① milligrams.
(round to the nearest whole number as needed.)

Explanation:

Step1: Calculate the daily dose

We know the weight in kilograms is \(19.05\) kg and the dose is \(4\) mg per kg.
Since there are \(24\) hours in a day and the dose is given every \(6\) hours, the number of times the dose is given in a day is \(\frac{24}{6}=4\) times.
The daily dose \(D\) is calculated by the formula \(D = 4\times19.05\times4\).
First, \(4\times19.05 = 76.2\).
Then, \(76.2\times4=304.8\).

Answer:

\(305\)
