Which condition is associated with decreased serum hemoglobin, hematocrit, and transferrin saturation levels? A. Scurvy B. Iron-deficiency anemia Correct C. Folic acid deficiency anemia D. Vitamin B12 deficiency anemia With iron-deficiency anemia, there are decreased levels of hemoglobin, hematocrit, and transferrin saturation (amount of serum iron that is bound).

Obese children C. Nonobese adults Correct D. Nonobese children Triceps skinfold testing is most appropriate with nonobese adults who are easier to test with this method. The use of triceps skinfold testing is not recommended in children or obese adults because of difficulty with technique and inconclusive results. Awarded 1.0 points out of 1.0 possible points. 8. 8.ID: 986687169 Which intervention will lower serum total cholesterol and improve HDL and LDL levels? A. Decrease fiber in the diet. B. Increase physical activity Correct C. Eliminate fat from the diet. D. Take a multivitamin supplement Increasing physical activity will improve the cholesterol levels. Increasing fiber would also improve cholesterol levels. Fat should not be eliminated because fatty acids are essential for nutrition.
