- A. Marasmus
- B. Kwashiorkor
- C. Anemia
- D. Noma
Correct answer: B
Rationale: Kwashiorkor is a form of severe malnutrition characterized by edema, fatty liver, and other symptoms, typically resulting from inadequate protein intake despite adequate calorie intake.
2. Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?
- A. Vitamin A
- B. Vitamin B12
- C. Vitamin C
- D. Vitamin E
Correct answer: D
Rationale: Vitamin E is an antioxidant that helps protect eye health and prevent macular degeneration.
3. Which mineral is a principal component of cell membranes?
- A. phosphorus
- B. magnesium
- C. iron
- D. iodine
Correct answer: A
Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.
4. A healthcare professional is reviewing the lab results of a client who has bulimia nervosa. The professional should notify the provider of which of the following results?
- A. White Blood Cells 5,200/mm³
- B. Hemoglobin 14 g/dL
- C. Magnesium 1.6 mg/dL
- D. Potassium 3.2 mEq/L
Correct answer: D
Rationale: A potassium level of 3.2 mEq/L is below normal and requires provider notification, especially in clients with bulimia nervosa who are at risk of electrolyte imbalances. Low potassium levels can lead to serious complications like cardiac arrhythmias. The other options are within or close to the normal range and would not be a priority for notification.
5. Select all that apply. Which nutrients are needed by the body to make hemoglobin?
- A. Iron
- B. Vitamin B12
- C. Niacin
- D. Folate
Correct answer: A
Rationale: The correct answer is A: Iron. Iron is an essential nutrient needed by the body to make hemoglobin, the protein in red blood cells that carries oxygen. While other nutrients like vitamin B12, niacin, and folate are important for various bodily functions, they are not directly involved in the production of hemoglobin. Vitamin B12 is essential for nerve function and DNA synthesis, niacin is important for metabolism, and folate is crucial for cell division and DNA synthesis. Therefore, only iron is specifically required for hemoglobin production.
