A 10 month old child weighing 8kg has Bitot spots in both eyes. Which of the following is the most appropriate schedule to prescribe vitamin A to this child –
**Core Concept**
Vitamin A supplementation is crucial in treating vitamin A deficiency, which can cause Bitot spots in infants. The World Health Organization (WHO) recommends a specific regimen for vitamin A supplementation in children with vitamin A deficiency.
**Why the Correct Answer is Right**
The correct answer is based on the WHO's guidelines for vitamin A supplementation in children with vitamin A deficiency. The recommended schedule is a single dose of 100,000 IU of vitamin A, followed by a second dose after 24 hours. This is because vitamin A is fat-soluble, and administering two doses separated by 24 hours allows for better absorption and utilization of the vitamin. The second dose is crucial in replenishing the body's stores of vitamin A and preventing further deficiency.
**Why Each Wrong Option is Incorrect**
**Option A:** Administering a single dose of vitamin A without a follow-up dose may not be sufficient to replenish the body's stores of vitamin A and may lead to continued deficiency.
**Option B:** Administering a dose of vitamin A every 8 hours for 2 days is not the recommended schedule for vitamin A supplementation in children with vitamin A deficiency.
**Option C:** Administering a dose of vitamin A every 12 hours for 3 days is also not the recommended schedule for vitamin A supplementation in children with vitamin A deficiency.
**Clinical Pearl / High-Yield Fact**
Remember that vitamin A deficiency can cause night blindness, dry skin, and Bitot spots, and that the WHO recommends a single dose of 100,000 IU of vitamin A, followed by a second dose after 24 hours, for children with vitamin A deficiency.
**Correct Answer:** C.
