Which assessment tool uses calf circumference, BMI, weight loss, and acute disease status to screen for malnutrition risk in community-dwelling older adults?
Answer: Mini Nutritional Assessment (MNA)
The Mini Nutritional Assessment (MNA) was specifically developed and validated for screening and assessing malnutrition risk in elderly patients in community and long-term care settings.
Refeeding syndrome is primarily caused by rapid shifts in which electrolyte following re-initiation of feeding after prolonged starvation?
Answer: Phosphorus
Refeeding syndrome is primarily characterized by severe hypophosphatemia as insulin secretion stimulated by carbohydrate intake drives phosphorus into cells for ATP synthesis.
Which dietary fiber is most effective at reducing LDL cholesterol by binding bile acids in the intestinal lumen?
Answer: Beta-glucan (soluble fiber)
Beta-glucan, a viscous soluble fiber found in oats and barley, is one of the most evidence-based dietary fibers for LDL reduction through bile acid sequestration and increased cholesterol catabolism.
Insulin resistance in type 2 diabetes is most directly associated with impaired glucose uptake in which tissue?
Answer: Skeletal muscle and adipose tissue
Skeletal muscle and adipose tissue are the primary insulin-sensitive tissues where GLUT4-mediated glucose uptake is impaired in type 2 diabetes due to post-receptor signaling defects.
The Academy of Nutrition and Dietetics recommends that protein intake during pregnancy increase by approximately how many additional grams per day above the non-pregnant RDA?
Answer: 25 g/day
The RDA for protein during pregnancy increases by approximately 25 g/day above the non-pregnant recommendation to support fetal growth, placental development, and expanded maternal blood volume.
Which gastrointestinal condition is characterized by malabsorption triggered by gluten, an immune-mediated destruction of intestinal villi?
Answer: Celiac disease
Celiac disease is an autoimmune disorder in which gluten ingestion triggers T-cell mediated destruction of duodenal and jejunal villi, causing malabsorption of fat, fat-soluble vitamins, iron, and calcium.
Which nutrient is involved in collagen synthesis and functions as a cofactor for prolyl hydroxylase, making it essential for wound healing?
Answer: Vitamin C
Vitamin C is required as a cofactor for prolyl and lysyl hydroxylases, enzymes that catalyze hydroxylation of proline and lysine residues essential for collagen triple helix stability and cross-linking.
