A nurse is teaching a client about water-soluble vitamins. Which of the following vitamins should the nurse include?

Choice A reason: Vitamin A is a fat-soluble vitamin stored in the liver, not water-soluble. It supports vision, immune function, and skin health but is absorbed with dietary fats and stored in body tissues. Unlike water-soluble vitamins, excess intake can lead to toxicity, as it is not readily excreted, making it an incorrect choice for this teaching. Choice B reason: Vitamin E is a fat-soluble vitamin, not water-soluble, functioning as an antioxidant to protect cell membranes. It is absorbed with fats and stored in adipose tissue and the liver. Unlike water-soluble vitamins, it is not excreted in urine, and excess amounts can accumulate, making it an incorrect choice for water-soluble vitamin teaching. Choice C reason: Vitamin C is a water-soluble vitamin essential for collagen synthesis, immune function, and antioxidant activity. It dissolves in water, is not stored in large amounts, and is excreted in urine, requiring regular dietary intake. This makes it the correct choice for teaching about water-soluble vitamins, as it aligns with their biochemical properties and physiological roles. Choice D reason: Vitamin D is a fat-soluble vitamin, not water-soluble, critical for calcium absorption and bone health. It is stored in fat tissues and the liver, with excess potentially leading to toxicity. Unlike water-soluble vitamins, it is not readily excreted, making it an incorrect choice for inclusion in teaching about water-soluble vitamins.
