Which risk factors increase the risk of atherosclerosis?

Correct Answer: D

Rationale: Smoking is a major risk factor for atherosclerosis. It significantly contributes to the buildup of plaque in the arteries and thereby increases the risk of cardiovascular diseases. On the other hand, exercise is generally beneficial for cardiovascular health and is not a risk factor for atherosclerosis. Excessive sun exposure and insufficient vaccinations have no established links to atherosclerosis, making them incorrect options for this question.

Correct Answer: C

Rationale: The correct answer is C: Choose high-fat meat instead of lean meat. High-fat meats are more calorie-dense than lean meats, which makes them a good choice for increasing calorie intake. This is crucial for patients with stomach cancer who want to avoid weight loss and wasting. Choice A is incorrect because skim milk or water contains fewer calories than whole fat milk. Choice B is also incorrect because peanut butter and nuts are high in calories and therefore should not be avoided when trying to increase calorie intake. Finally, choice D is not a good suggestion to increase calorie intake as alcohol does not provide the necessary nutrients needed for a balanced diet. In fact, excessive alcohol can harm the liver and other organs, and it's not a reliable source of calories.

Correct Answer: D

Rationale: MI Paste is contraindicated in children under six and in individuals with a milk casein allergy. The reason is that MI Paste contains casein phosphopeptide, which is derived from milk. Therefore, it may cause allergic reactions in those who are sensitive to milk proteins. Pregnant women (Choice C) are not contraindicated for using MI Paste unless they have a known allergy to milk casein. Hence, the correct answer is 'D: Both A and B'.

Correct Answer: A

Rationale: Cholesterol is a precursor for the synthesis of sex hormones like estrogen and testosterone.

Correct Answer: C

Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.

Correct Answer: C

Rationale: Adolescence is the most critical stage for building bone mass, which plays a significant role in preventing osteoporosis in later life. During adolescence, approximately 45% of adult bone mass is formed. Although bone mass can be built during infancy, early childhood, and young adulthood, it is not as significant as during adolescence, making choices A, B, and D incorrect. Therefore, focusing on adequate nutrition and physical activity during adolescence is vital for long-term bone health.

Correct Answer: A

Rationale: Regular intake of prescription drugs like steroids and diuretics can lead to the loss of potassium in the body, causing a condition known as hypokalemia. Therefore, people on these medications require careful monitoring and often need potassium supplementation to prevent this deficiency. The other options, selenium, iodine, and chloride, are incorrect because there is no specific link between their deficiency and the regular use of steroids and diuretics.

Correct Answer: C

Rationale: The large intestine is the organ that is primarily responsible for the absorption of water and vitamin K in the human body. A disease like ulcerative colitis can disrupt these functions by causing inflammation and ulcers in the lining of the large intestine, leading to digestive issues. The stomach (Choice A) primarily functions to break down and digest food, not to absorb water and vitamins. The pancreas (Choice B) secretes enzymes to aid in digestion and hormones to regulate blood sugar, but does not absorb water and vitamins. The small intestine (Choice D) is primarily responsible for absorbing nutrients from digested food, but not specifically water and vitamin K. Therefore, these other choices are incorrect.

Correct Answer: D

Rationale: The correct answer is 'D. All of the above'. This is because, according to regulations, food labels must include the information on total fat, saturated fat, and trans fat. These types of fats are crucial for consumers to monitor, as they can significantly affect heart health. Choices A, B, and C are all correct, but they are only parts of the total information that must be provided. Therefore, the most comprehensive answer is 'D. All of the above'.
