Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?
- A. The DRIs replace the older recommended daily allowances
- B. Current DRIs attempt to estimate required nutrients to improve long-term health
- C. DRIs specifically address individuals whose requirements are affected by a disease state
- D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients
Correct Answer: C
Rationale: The correct answer is C. DRIs are intended for the general population and do not specifically address disease states, which are managed with different clinical guidelines. Choice A is correct as DRIs have replaced the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate the required nutrients for long-term health. Choice D is correct as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.
Which dietary supplement is often recommended for patients taking statins to lower cholesterol?
- A. Iron
- B. Coenzyme Q10
- C. Calcium
- D. Magnesium
Correct Answer: B
Rationale: Coenzyme Q10 is often recommended for patients on statins because it may help reduce muscle pain, a common side effect of these medications. Iron (Choice A) is not typically recommended for patients taking statins to lower cholesterol. Calcium (Choice C) and Magnesium (Choice D) are not specifically indicated for addressing muscle pain associated with statin use, making them less suitable choices in this scenario.
Which of the following is a common sign of vitamin D deficiency?
- A. Brittle nails
- B. Muscle weakness
- C. Night blindness
- D. Hair loss
Correct Answer: B
Rationale: Muscle weakness is a common sign of vitamin D deficiency. Vitamin D is essential for calcium absorption and bone health, and its deficiency can lead to muscle weakness. Brittle nails (Choice A) are not typically associated with vitamin D deficiency. Night blindness (Choice C) is related to vitamin A deficiency, not vitamin D deficiency. Hair loss (Choice D) can be linked to various factors, but it is not a common sign of vitamin D deficiency.
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.

- A. confusion
- B. profuse sweating
- C. hypertension

Rationale: Leg cramps are a common complication during hemodialysis due to shifts in fluid and electrolyte levels that occur during the treatment. Confusion (choice A) is not a common complication specifically related to hemodialysis. Profuse sweating (choice B) is not typically associated with hemodialysis complications. Hypertension (choice C) might be a pre-existing condition in some patients but is not a direct common complication of hemodialysis.
