Vitamins and Minerals

Overview

Vitamins and minerals are micronutrients that act as catalysts for metabolic and chemical reactions in the body. While needed in small amounts, their deficiency or excess can lead to significant health problems. Nursing care involves identifying patients at risk for imbalances and educating them on food sources and safe supplementation.

Key nursing concepts

• Vitamins are organic compounds required for metabolic functions.
• Water-soluble vitamins (B, C) are not stored and require daily intake.
• Fat-soluble vitamins are stored in liver and fatty tissues; risk of toxicity.
• Minerals like calcium and iron are inorganic elements for structure and oxygen transport.
• Deficiencies can lead to specific syndromes (e.g., rickets, anemia).
• Nutrient-drug interactions can significantly alter medication efficacy.

Important nursing considerations

• Vitamin K intake must be consistent for patients taking warfarin.
• Vitamin B12 supplementation is often necessary for strict vegans.
• Vitamin C enhances the absorption of iron supplements.
• Vitamin D is necessary for calcium absorption and bone health.
• Monitor for toxicity in fat-soluble vitamins (A, D, E, K).
• Assess for signs of deficiency like scurvy (Vit C) or pellagra (B3).

Patient teaching

• Take iron supplements with orange juice, not milk or tea.
• If taking warfarin, keep your intake of green leafy vegetables consistent.
• Do not take megadoses of fat-soluble vitamins without medical supervision.
