2 year old boy of weight 12 kg with vitamin A deficiency what is oral dose of vitamin A
**Core Concept**
Vitamin A deficiency is a critical public health concern, especially in children under 5 years of age. The World Health Organization (WHO) recommends urgent treatment with vitamin A to prevent and treat xerophthalmia and night blindness, as well as to reduce mortality in children with vitamin A deficiency.
**Why the Correct Answer is Right**
The oral dose of vitamin A for a child with vitamin A deficiency is crucial to prevent complications. According to the WHO, the recommended dose for children 1-5 years of age is 100,000 IU (International Units) of vitamin A on the first day, followed by 200,000 IU on the following day. This dose is repeated after 2 weeks and after 4 weeks if the child remains at risk. For a 2-year-old boy weighing 12 kg, this dose is appropriate, as it helps to rapidly replenish vitamin A stores and prevent further deficiency.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not correct as it does not follow the recommended WHO guidelines for vitamin A supplementation in children.
**Option B:** This option is incorrect because it does not account for the child's age and weight, which are critical factors in determining the appropriate dose of vitamin A.
**Option C:** This option is not correct as it does not provide the correct dose of vitamin A for a child with vitamin A deficiency, as per the WHO recommendations.
**Clinical Pearl / High-Yield Fact**
It is essential to note that vitamin A supplementation should only be given under the supervision of a healthcare professional, as high doses of vitamin A can be toxic.
**Correct Answer:** A. 100,000 IU of vitamin A on the first day, followed by 200,000 IU on the following day.
