1. Carmen discovers that the DASH diet contains more fiber and ____ compared to that of the typical American diet.

• A. vitamin C
• B. iron
• C. potassium
• D. sodium

Correct answer: C

Rationale: The correct answer is C: 'potassium.' The DASH diet is rich in potassium, which helps lower blood pressure, making it more effective than the typical American diet, which is often low in this essential mineral. Choice A, 'vitamin C,' is incorrect as the comparison is about fiber and another nutrient, not vitamin C. Choice B, 'iron,' is incorrect as the discussion is about fiber and a mineral that helps lower blood pressure, not iron. Choice D, 'sodium,' is incorrect as the DASH diet actually focuses on reducing sodium intake for better blood pressure control, so it wouldn't be a nutrient found in higher amounts compared to the typical American diet.

2. A patient has begun taking furosemide to manage heart failure. What food should the nurse recommend that the patient consume frequently while taking this drug?

• A. legumes
• B. cabbage
• C. peanut butter
• D. bananas

Correct answer: D

Rationale: Furosemide is a diuretic that can lead to potassium loss; therefore, it is recommended that patients consume potassium-rich foods like bananas to prevent hypokalemia.

3. What is the most effective way to limit the number of microorganisms in the hospital?

• A. Using strict aseptic technique in all procedures
• B. Wearing a mask and gown when caring for all patients with communicable diseases
• C. Sterilizing all instruments
• D. Handwashing

Correct answer: A

Rationale: The most effective way to limit the number of microorganisms in the hospital is by using strict aseptic technique in all procedures. This approach ensures that the risk of introducing harmful microorganisms into the hospital environment or patients is minimized. Choice B, wearing a mask and gown when caring for patients with communicable diseases, is important but not as comprehensive as using aseptic technique in all procedures. Sterilizing all instruments (Choice C) is crucial for preventing infections but may not address all avenues of microorganism transmission. Handwashing (Choice D) is a fundamental practice in infection control but alone may not be as effective as utilizing aseptic techniques in all procedures to limit microorganisms in the hospital.

4. 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.

5. Which nutrient is most important for pregnant women to prevent neural tube defects?

• A. Iron
• B. Folate
• C. Calcium
• D. Vitamin D

Correct answer: B

Rationale: Folate (or folic acid) is crucial for the prevention of neural tube defects during pregnancy.
