1. What is the function of villi and microvilli in the GI tract?

• A. produce bile
• B. kill bacteria
• C. produce vitamin K
• D. increase the surface area for absorption

Correct answer: D

Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.

2. What is the recommended dietary intervention for a patient with hyperlipidemia?

• A. Increase saturated fat intake
• B. Reduce fiber intake
• C. Increase dietary fiber intake
• D. Reduce protein intake

Correct answer: C

Rationale: Increasing dietary fiber can help reduce cholesterol levels in patients with hyperlipidemia.

3. What is the digestive action of lipase?

• A. It breaks down carbohydrates
• B. It breaks down proteins
• C. It breaks down lipids
• D. It aids in fat digestion

Correct answer: C

Rationale: Lipase is an enzyme that specifically breaks down lipids (fats) during the process of digestion, converting them into fatty acids and glycerol. This is why option C is the correct answer. Although option D is partially correct, it's less specific than option C. Lipase does not break down carbohydrates or proteins, so options A and B are incorrect.

4. A nearby community provides blood pressure screening, height and weight measurement, smoking cessation classes and aerobics class services. This type of program is referred to as

• A. outreach program
• B. hospital extension program
• C. barangay health program
• D. wellness program

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. The major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet.

• A. True
• B. False
• C.
• D.

Correct answer: B

Rationale: It is false that the major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet. While dietary cholesterol can have some impact on total cholesterol levels, it is not the major determinant. The amount and types of fats consumed, particularly saturated and trans fats, have a more significant impact on blood cholesterol levels. Therefore, a diet high in these types of fats can lead to high cholesterol, irrespective of the amount of dietary cholesterol consumed. This is why it is essential to maintain a balanced diet with a limited intake of saturated and trans fats.
