All of the following are vitamin deficiencies in children except?

Appeared in: JODHPUR AIIMS SNO-2018

Explanation

Simple Goiter is the correct answer because it is not caused by a vitamin deficiency.
It results from a deficiency of iodine, which is an essential mineral, not a vitamin.
The thyroid gland enlarges in an attempt to capture more iodine from the blood to produce thyroid hormones.
The other three options—Rickets, Megaloblastic Anaemia, and Bitot's Spots—are all directly caused by deficiencies of specific vitamins (D, B12/B9, and A, respectively).

Option A: Rickets is incorrect because it is a classic example of a vitamin deficiency disease in children.
Option C: Megaloblastic Anaemia is incorrect because it is caused by a deficiency of B vitamins, specifically Vitamin B12 and/or Folic Acid (Vitamin B9).
Option D: Bitot's Spots are incorrect because they are a specific clinical sign of Vitamin A deficiency.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of diseases caused by nutrient deficiencies, specifically differentiating between vitamin and mineral deficiencies as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in identifying signs of nutritional deficiencies during pediatric assessments and providing dietary education to parents.
Recognizing that goiter is linked to iodine (a mineral) and not a vitamin is essential for correct patient teaching and understanding public health initiatives like salt iodization.
What if? If a child presents with bowed legs and delayed motor milestones, the nurse should suspect Rickets (Vitamin D deficiency) and inquire about sun exposure and dietary intake of milk and fortified foods, rather than focusing on iodine intake.
