A client is diagnosed with a severe deficiency in vitamin C. Which of the following symptoms would be most directly attributable to this deficiency?
- AWeakened connective tissue, leading to bleeding gums and poor wound healing.
- BBone demineralization and increased risk of fractures.
- CImpaired blood clotting and excessive bleeding.
- DPoor night vision and dry eyes.
Show answer & explanationAnswer & explanation
Correct answer: A. Weakened connective tissue, leading to bleeding gums and poor wound healing.
Vitamin C (ascorbic acid) is crucial for collagen synthesis, a key component of connective tissues. A severe deficiency leads to scurvy, characterized by weakened connective tissues, bleeding gums, and impaired wound healing.
Why the other options are wrong
- B. Bone demineralization and increased fracture risk are associated with vitamin D and calcium deficiencies.
- C. Impaired blood clotting is more commonly associated with vitamin K deficiency.
- D. Poor night vision and dry eyes are symptoms of vitamin A deficiency.
Vitamin C (Ascorbic Acid)
An essential water-soluble vitamin that acts as an antioxidant and is crucial for collagen synthesis.
- Required for collagen production (connective tissue).
- Supports immune function.
- Deficiency causes scurvy (bleeding gums, poor wound healing).
Memory trick: Vitamin C is for 'Collagen' and 'Cure' (healing).
