1. What is the most important concern immediately after a myocardial infarction?

• A. Reducing cholesterol intake
• B. Allowing cardiac rest for healing
• C. Reducing saturated fat intake
• D. Eating several small meals each day

Correct answer: B

Rationale: Immediately after a myocardial infarction, the primary concern is to allow the heart to rest and heal to prevent further damage. This is why choice B is the correct answer. While choices A, C, and D might be a part of the long-term management plan following a myocardial infarction, they are not the immediate priority. Reducing cholesterol and saturated fat intake, as well as adjusting eating habits can help prevent future heart issues, but do not directly contribute to the immediate recovery post-myocardial infarction.

2. Which foods should be avoided on a low-potassium diet? (SATA)

• A. Bananas
• B. A, C
• C. Sweet potatoes
• D. Frozen corn

Correct answer: B

Rationale: Bananas, sweet potatoes, and orange juice are high in potassium.

3. What physiologic role does calcium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance.

Correct answer: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

4. Which group is least susceptible to insufficient intake of protein?

• A. The elderly
• B. Individuals with low income
• C. Adults participating in endurance exercise
• D. Patients who are chronically ill

Correct answer: C

Rationale: Adults who participate in endurance exercise are typically more aware of their nutritional needs and have higher protein intake compared to other groups. The rationale behind why the other choices are incorrect is as follows: A: The elderly are often at a higher risk of insufficient protein intake due to various factors such as reduced appetite, dental issues, and decreased muscle mass. B: Individuals with low income may struggle to afford protein-rich foods, making them more susceptible to insufficient protein intake. D: Patients who are chronically ill may have specific dietary restrictions or challenges that can lead to inadequate protein consumption.

5. What is a common symptom of vitamin D deficiency?

• A. Hair loss
• B. Night blindness
• C. Bone pain
• D. Rashes

Correct answer: C

Rationale: The correct answer is C: Bone pain. Vitamin D deficiency often leads to bone pain and weakness as it plays a crucial role in maintaining bone health by aiding in the absorption of calcium. Hair loss (choice A) is not a common symptom of vitamin D deficiency. Night blindness (choice B) is typically associated with vitamin A deficiency, not vitamin D deficiency. Rashes (choice D) are not a common symptom of vitamin D deficiency.
