Vitamin A โ๏ธ Correct
๐ป Vitamin A is a fat-soluble vitamin that requires normal fat absorption in the small intestine for adequate uptake.
๐ป Clients with malabsorption disorders, such as celiac disease, cystic fibrosis, Crohn's disease, chronic pancreatitis, or short bowel syndrome, have difficulty absorbing dietary fats and are therefore at risk for vitamin A deficiency.
๐ป Deficiency can lead to night blindness, dry eyes (xerophthalmia), dry skin, impaired immune function, and delayed wound healing.
๐ป The nurse should monitor for visual changes, assess nutritional status, and reinforce adherence to prescribed vitamin supplementation.
๐ป Maintaining adequate vitamin A levels is essential for vision, epithelial tissue integrity, immune function, and normal growth.
๐ Key Point: Vitamin A deficiency commonly occurs with fat malabsorption.
โ
Vitamin D โ๏ธ Correct
๐ธ Vitamin D is a fat-soluble vitamin that depends on normal fat absorption for intestinal uptake.
๐ธ Deficiency results in decreased calcium and phosphorus absorption, leading to poor bone mineralization.
๐ธ Children may develop rickets, while adults are at risk for osteomalacia or osteoporosis.
๐ธ The nurse should monitor calcium, phosphorus, vitamin D levels, and bone health, and encourage prescribed supplementation.
๐ธ Adequate vitamin D is essential for healthy bones, teeth, and neuromuscular function.
๐ Key Point: Vitamin D deficiency causes impaired calcium absorption and bone disease.
โ
Vitamin E โ๏ธ Correct
๐งฟ Vitamin E is a fat-soluble antioxidant that protects cell membranes from oxidative damage.
๐งฟ Malabsorption disorders decrease vitamin E absorption, increasing the risk of deficiency.
๐งฟ Deficiency may cause peripheral neuropathy, muscle weakness, ataxia, decreased reflexes, and hemolytic anemia, particularly in children.
๐งฟ The nurse should monitor neurological function and encourage prescribed supplementation if indicated.
๐งฟ Adequate vitamin E supports neurological health, red blood cell integrity, and immune function.
๐ Key Point: Vitamin E deficiency can lead to neurological and hematologic problems.
โ
Vitamin K โ๏ธ Correct
๐ต๏ธ Vitamin K is a fat-soluble vitamin required for the liver to synthesize clotting factors II, VII, IX, and X.
๐ต๏ธ Fat malabsorption can reduce vitamin K absorption, increasing the risk of bleeding and prolonged clotting times.
๐ต๏ธ Deficiency may present with easy bruising, bleeding gums, epistaxis, prolonged PT/INR, or excessive bleeding after injury.
๐ต๏ธ The nurse should monitor coagulation studies and assess for signs of bleeding.
๐ต๏ธ Adequate vitamin K is necessary for normal blood coagulation and bone metabolism.
๐ Key Point: Vitamin K deficiency increases bleeding risk.
