1. 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.

2. How many grams of protein per day are recommended for a person weighing 150 lbs?

• A. 120
• B. 85
• C. 187.5
• D. 54

Correct answer: D

Rationale: The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight. To convert pounds to kilograms, divide the weight in pounds by 2.2. Therefore, a 150 lb person weighs approximately 68 kg (150 / 2.2 = 68). Multiplying 68 kg by 0.8 grams gives us 54 grams of protein per day. Choices A, B, and C are incorrect as they do not align with the RDA calculation based on body weight.

3. Why are LDLs known as the 'bad' type of cholesterol?

• A. LDL (Low-Density Lipoprotein) is considered 'bad' cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis).
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: LDL (Low-Density Lipoprotein) is known as the 'bad' type of cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis). This narrowing can restrict blood flow and increase the risk of serious cardiovascular conditions. The statement and the reason are directly related because the adherence of LDL to arterial walls and the subsequent narrowing of the lumen are the primary reasons why it is considered detrimental to heart health. Choice B is incorrect because the statement and reason are related. Choice C is incorrect because both the statement and the reason are correct. Choice D is incorrect because the statement correctly identifies LDL as the 'bad' type of cholesterol due to its actions in the arteries.

4. Which enzyme initiates protein digestion in the stomach?

• A. Pepsin
• B. Salivary Amylase
• C. CCK
• D. Secretin

Correct answer: A

Rationale: Pepsin is the enzyme that initiates protein digestion in the stomach. It breaks down proteins into smaller peptides, aiding in their further digestion and absorption in the intestines. Salivary Amylase (Choice B) functions in breaking down dietary carbohydrates in the mouth, not proteins. CCK (Choice C) and Secretin (Choice D) are hormones involved in the digestion of fats and carbohydrates, not proteins. Therefore, Choices B, C, and D are incorrect in the context of protein digestion in the stomach.

5. What characterizes Obsessive Compulsive Disorder?

• A. Uncontrollable impulse to perform an act or ritual repeatedly
• B. Persistent thoughts and behavior
• C. Recurring unwanted and disturbing thoughts
• D. Pathological persistence of unwilled thoughts

Correct answer: A

Rationale: Obsessive Compulsive Disorder (OCD) is characterized by the uncontrollable impulse to perform an act or ritual repeatedly (Choice A). This is driven by recurring unwanted and disturbing thoughts (Choice C), but the distinguishing factor is the compulsive behavior, making choice A the most accurate. While choice B can be seen as true, it lacks the specific detail of the compulsive behavior that makes A a better answer. Choice D is not incorrect, but it uses terminology that is less precise and less commonly used to describe OCD, making it a less accurate choice than A. The provided rationale is not relevant to the question.
