What is the best dietary advice for a patient with iron-deficiency anemia?
- A. Increase dairy consumption
- B. Increase vitamin C intake
- C. Reduce red meat consumption
- D. Increase fiber intake
Correct Answer: B
Rationale: The best dietary advice for a patient with iron-deficiency anemia is to increase vitamin C intake. Vitamin C enhances the absorption of non-heme iron, which can help improve iron-deficiency anemia. Choices A, C, and D are not the best options for this condition. Increasing dairy consumption (Choice A) may not directly address the iron deficiency. Reducing red meat consumption (Choice C) may limit heme iron intake, which is easily absorbed by the body. Increasing fiber intake (Choice D) is generally beneficial but is not specifically recommended as the top advice for iron-deficiency anemia.
Diseases of the heart and blood vessels are collectively referred to as _____.
- A. Coronary artery disease
- B. Cardiovascular disease
- C. Coronary heart disease
- D. Coronary vessel disease
Correct Answer: B
Rationale: The correct term for diseases of the heart and blood vessels is cardiovascular disease. While coronary artery disease (Choice A) specifically involves the narrowing of coronary arteries, it is just one type of cardiovascular disease. Coronary heart disease (Choice C) is also a specific condition related to the heart's blood vessels. Choice D, coronary vessel disease, is not a commonly used term to describe diseases of the heart and blood vessels. Therefore, Choice B, cardiovascular disease, is the most inclusive and appropriate term to refer to these conditions.
Plant stanols and sterols help to lower LDL cholesterol and are often added to which food product?
- A. margarine
- B. milk
- C. cereal
- D. yogurt
Correct Answer: A
Rationale: Plant stanols and sterols are commonly added to margarine to help lower LDL cholesterol levels. Margarine acts as a vehicle for these compounds, making it easier for individuals to incorporate them into their daily diet. While milk, cereal, and yogurt are healthy food options, they are not typically enriched with plant stanols and sterols for cholesterol-lowering purposes, making them less likely candidates as the correct answer.
What dietary factor raises triglyceride levels?
- A. high refined carbohydrate intake
- B. low soluble fiber intake
- C. high iron intake
- D. low fat intake
Correct Answer: A
Rationale: The correct answer is A: high refined carbohydrate intake. High intake of refined carbohydrates, such as sugars and white flour, can lead to elevated triglyceride levels, increasing the risk of cardiovascular disease. Choice B, low soluble fiber intake, is incorrect because soluble fiber actually helps lower triglyceride levels. Choice C, high iron intake, is incorrect as iron intake is not directly linked to raising triglyceride levels. Choice D, low fat intake, is also incorrect as not all fats raise triglyceride levels; it depends on the type of fat consumed.
Each is a portion of the alimentary canal, except one. Which is the exception?
- A. Oral cavity
- B. Pharynx
- C. Larynx
- D. Esophagus
Correct Answer: C

The alimentary canal is involved in the digestive process and includes structures like the oral cavity (mouth), pharynx, and esophagus. Choices A, B, and D are parts of the alimentary canal, where digestion occurs, making them incorrect answers.
