The clinical condition shown is associated with which vitamin deficiency?
Appeared in: NORCERT 8 Mains-2025
Explanation
The image displays Genu Varum (bow-legs), a characteristic deformity of Rickets.
Rickets is a disease of growing bones caused by inadequate mineralization, primarily due to Vitamin D deficiency.
Vitamin D is crucial for calcium and phosphate absorption, which are essential for bone hardening. Its deficiency leads to soft, pliable bones that bend under pressure.
Other signs of Rickets include Rachitic Rosary (beading at costochondral junctions), Harrison's groove, and widening of wrists and ankles.
Why Other Options Were Wrong
Option A: Vitamin K is involved in blood coagulation by aiding the synthesis of clotting factors II, VII, IX, and X. Its deficiency causes bleeding disorders, not skeletal deformities like bow-legs.
Option C: Vitamin A deficiency primarily affects vision (leading to night blindness and xerophthalmia), immune function, and epithelial cell integrity. It is not associated with the bone-bending deformities seen in Rickets.
Option D: Vitamin C (ascorbic acid) deficiency causes Scurvy. Scurvy affects collagen synthesis, leading to fragile capillaries, poor wound healing, bleeding gums, and subperiosteal hemorrhages. While it involves bone pain, it does not cause the characteristic bowing of long bones seen in Rickets.

Clinical Relevance
Nursing practice connection: Knowing Identification of clinical signs of vitamin deficiencies, specifically Rickets helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Nurses play a vital role in identifying children at risk for Vitamin D deficiency, such as exclusively breastfed infants without supplementation, children with dark skin, and those with limited sun exposure.
Patient education is a key nursing intervention. This includes teaching parents about the importance of Vitamin D supplements for infants, safe sun exposure, and dietary sources of vitamin D and calcium.
During physical assessments, nurses should look for early signs of Rickets, such as craniotabes (soft skull bones), wrist widening, and delayed motor milestones, to facilitate early diagnosis and treatment.
How to Approach the Question
First, carefully analyze the image provided. Identify the key clinical sign being displayed. In this case, it's the outward bowing of the legs.
Name the clinical sign. The outward bowing is known as Genu Varum or bow-legs.
Recall the most common disease associated with this sign in a child. Genu Varum is a classic feature of Rickets.
Access your knowledge of nutritional deficiencies. What is the primary cause of nutritional Rickets?
Connect the disease to its cause: Rickets is caused by Vitamin D deficiency.
Finally, select the option that matches your conclusion. Compare your answer with the other options to ensure they are incorrect for this specific presentation.
