A child is prescribed ciprofloxacin 40 mg/kg/day in 4 divided doses. If the child weighs 15 kg, what is the dose per administration?
Appeared in: UP NHM CHO 7 Sept 2022 (Shift-2)
Explanation
- The first step is to calculate the total daily dose by multiplying the prescribed dose per kilogram by the child's weight.
- Total Daily Dose = 40 mg/kg/day × 15 kg = 600 mg/day.
- The second step is to divide the total daily dose by the number of administrations per day to find the single dose amount.
- Dose per Administration = 600 mg/day ÷ 4 doses = 150 mg/dose.
Why Other Options Were Wrong
- Option A: This dose (75 mg) would result from an incorrect calculation, either by dividing the total daily dose (600 mg) by 8 instead of 4, or by incorrectly calculating the total daily dose using 20 mg/kg/day instead of 40 mg/kg/day.
- Option C: This dose (100 mg) would result from incorrectly dividing the total daily dose (600 mg) by 6 instead of 4.
- Option D: This dose (200 mg) would result from incorrectly dividing the total daily dose (600 mg) by 3 instead of 4.

Clinical Relevance
- Nursing practice connection: Use the key finding related to Pediatric Dose Calculation to guide bedside assessment, documentation, and the next nursing action.
- Accurate pediatric dose calculation is a critical nursing skill to prevent medication errors, which can have severe consequences in children due to their smaller body mass and developing organ systems.
- The 'seven rights' of medication administration (right patient, right drug, right dose, right route, right time, right documentation, right reason) are especially crucial in pediatrics.
- What if the child's weight was recorded in pounds (lbs)? The nurse must first convert the weight to kilograms (1 kg = 2.2 lbs) before performing the dose calculation to avoid a significant error.
How to Approach the Question
- First, identify all the necessary information provided in the question: the drug dose (40 mg/kg/day), the child's weight (15 kg), and the frequency of administration (4 divided doses).
- This is an analytical/calculation question. The goal is to find the amount for a single dose.
- Step 1: Calculate the total amount of medication the child will receive in one full day. Multiply the dose per kg by the child's weight.
- Step 2: Calculate the amount for one single administration. Divide the total daily dose by the number of times the medication is given per day.
- Step 3: Compare your calculated result with the given options to find the correct answer.
