A 55-year-old male patient has high cholesterol and triglycerides. He is at risk for infection related to:
A) Protein-calorie deficiency
B) Regulation of cellular proliferation
C) Excess of trace elements
D) Excess fatty acids
Ans: D
Feedback: Fatty acids are the building blocks that make up the structural components of cell membranes. Lipids are precursors of vitamins A, D, E, and K as well as cholesterol. Both excess and deficit of fatty acids have been found to suppress immune function. Inadequate intake of vitamins that are essential for DNA and protein synthesis may lead to protein-calorie deficiency and subsequently to impaired immune function. Vitamins also help in the regulation of cell proliferation and maturation of immune cells. Excess or deficit of trace elements in the diet suppresses immune function.
