Chapter 07: Nutrition Test Bank—Nursing MULTIPLE CHOICE 1. Mrs. Raymonds is a 24-year-old patient who has presented for a routine concern over her current weight. In your patient teaching with... her, you explain the importance of macronutrients. Which of the following is a macronutrient? a. Iron b. Thiamine c. Calcium d. Fat ANS: D Carbohydrates, protein, and fat are referred to as macronutrients because they are required in large amounts. Iron, thiamine, and calcium are minerals. DIF: Cognitive Level: Remembering (Knowledge) REF: p. 95 OBJ: Nursing process—assessment MSC: Physiologic Integrity: Physiologic Adaptation 2. Macronutrients are so named because they: a. have high molecular weights. b. form long chemical chains. c. tend to increase waist measurements. d. are required in large amounts. ANS: D Carbohydrates, protein, and fat are referred to as macronutrients because they are required in large amounts.

Vitamin E deficiency causes hyporeflexia, retinal degeneration, and red cell hemolysis in malnourished infants. Vitamin K deficiency results in prolonged bleeding and prothrombin time, which are hemorrhagic manifestations.
