Which disease is caused by Vitamin-C deficiency?

Appeared in: Bihar CHO - 2021

Explanation

  • Scurvy is the clinical syndrome caused by a severe and prolonged deficiency of Vitamin C (ascorbic acid).
  • Vitamin C is a crucial cofactor for enzymes involved in collagen synthesis. Impaired collagen production weakens connective tissues throughout the body.
  • The classic signs of scurvy, such as bleeding gums, easy bruising, and poor wound healing, are direct consequences of this defective collagen formation.
  • Humans cannot synthesize Vitamin C and must obtain it from dietary sources like citrus fruits, tomatoes, and green leafy vegetables.

Why Other Options Were Wrong

  • Option B: Rickets is caused by a deficiency of Vitamin D, not Vitamin C. It specifically affects bone development in growing children.
  • Option C: Osteomalacia is the adult counterpart to rickets, also caused by Vitamin D deficiency. It results in the softening of bones.
  • Option D: Beri-beri is caused by a deficiency of Thiamine (Vitamin B1), not Vitamin C.

Clinical Relevance
  • Nursing practice connection: Knowing Vitamin Deficiency Diseases helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
  • Nurses must be vigilant in identifying patients at risk for nutritional deficiencies, such as the elderly, chronic alcoholics, and individuals on highly restrictive diets.
  • Patient education is a critical nursing role. Teaching patients and their families about dietary sources of essential vitamins can prevent deficiency diseases like scurvy.
  • What if? If a child on a highly restrictive diet (e.g., due to autism spectrum disorder) presents with leg pain and a refusal to walk, a nurse should consider scurvy as a potential diagnosis, as this is a modern-day risk factor.
How to Approach the Question
  • This is a factual recall question that tests your knowledge of major vitamin deficiencies.
  • First, identify the core of the question: it asks for the disease linked to 'Vitamin-C deficiency'.
  • Mentally access your knowledge about vitamins. Recall that Vitamin C is also known as ascorbic acid.
  • Connect Vitamin C deficiency to its classic disease, which is Scurvy.
  • Review the other options to confirm your answer. Associate Rickets/Osteomalacia with Vitamin D and Beri-beri with Vitamin B1 (Thiamine).
  • Since Scurvy is the only option linked to Vitamin C deficiency, select it as the correct answer.
