Passage / Scenario
A child with asthma who weighs 4.69 kgA child with asthma has the following medication ordered: Theophylline 4 mg/kg/dose every 6 hrs. The child weighs 4.69 kg. Calculate the appropriate dose.
Correct answer
B
Rationale
To calculate the appropriate dose for the child, we first need to determine the child's weight in mg: 4.69 kg x 4 mg/kg = 18.76 mg. Since the dose is rounded to the nearest tenth, the correct dose is 18.7 mg (choice B). This calculation ensures the child receives the correct amount of medication based on their weight. Choices A, C, and D are incorrect as they do not accurately reflect the calculated dose.
