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. 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.

3. A client with iron deficiency anemia is being taught about dietary recommendations by a nurse. Which of the following dietary recommendations should the nurse include as a food that enhances iron absorption when consumed with nonheme iron?

• A. Tomato juice
• B. Tea
• C. Milk
• D. Dried Beans

Correct answer: A

Rationale: Tomato juice is the correct answer because it contains vitamin C, which enhances the absorption of nonheme iron. Vitamin C helps convert nonheme iron into a form that is easier for the body to absorb. Tea and milk should be avoided when consuming nonheme iron as they can inhibit iron absorption. Dried beans, although a good source of iron, do not enhance iron absorption when consumed with nonheme iron.

4. What is one of the best nutritional actions a caregiver can take to help a patient with Alzheimer's disease maintain appropriate body weight?

• A. Thicken liquids to prevent choking
• B. Supervise food planning and mealtimes
• C. Assist the person in completing a grocery checklist
• D. Feed the person their meals and snacks

Correct answer: B

Rationale: The correct answer is B, 'Supervise food planning and mealtimes'. This action ensures the patient with Alzheimer's disease maintains an appropriate diet and body weight, thus reducing the risk of malnutrition. While choices A, 'Thicken liquids to prevent choking', C, 'Assist the person in completing a grocery checklist', and D, 'Feed the person their meals and snacks', might be beneficial in certain circumstances, they do not directly contribute to the maintenance of appropriate body weight as effectively as supervising food planning and mealtimes does.

• A. activate vitamin D
• B. stimulate appetite
