You are to give ampicillin, with a recommended dose of 45 mg/kg, to a child with a mass of 28 kg. If stock on hand is 250 mg/ capsule, how many capsules should be given?
Express the number of capsules as an integer.
To determine the number of capsules that should be given, we need to divide the total dose required by the dose per capsule.
First, we need to calculate the total dose required:
Total dose = dose per kg * mass of the child
Total dose = 45 mg/kg * 28 kg
Total dose = 1260 mg
Next, we need to calculate the number of capsules required:
Number of capsules = total dose / dose per capsule
Number of capsules = 1260 mg / 250 mg/capsule
Number of capsules = 5.04
Since we cannot give a fraction of a capsule, we need to round up to the nearest whole number. Therefore, the child should be given 6 capsules.
To calculate the number of capsules needed, we can follow these steps:
Step 1: Calculate the total dose required:
Total Dose = Recommended Dose * Mass of the child
Total Dose = 45 mg/kg * 28 kg
Step 2: Divide the total dose by the available dose per capsule:
Number of Capsules = Total Dose / Dose per Capsule
Number of Capsules = (45 mg/kg * 28 kg) / 250 mg
Step 3: Calculate the final answer:
Number of Capsules = 4.032
Since we are asked to express the number of capsules as an integer, we need to round up to the nearest whole number. Therefore, the child should be given 5 capsules of ampicillin.
