Nursing Elites

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 movement of water from an area of lower solute concentration to one of higher solute concentration called?

• A. Hypodipsia
• B. Hypernatremia
• C. Hypokalemia
• D. Osmosis

Correct answer: D

Rationale: The correct answer is D, Osmosis. Osmosis is the process where water moves from an area of low solute concentration to an area of high solute concentration. This movement equalizes the solute concentration in intracellular and extracellular fluids. Choices A, B, and C are incorrect because they do not describe the movement of water based on solute concentration levels.

3. The nurse is assessing a client with a new diagnosis of Listeria food poisoning. What action should the nurse take first?

• A. Educate the client on safe food practices.
• B. Start a traceback to identify the source of the outbreak.
• C. Report the case to the county board of health.
• D. Ask the client if they have consumed any unpasteurized products.

Correct answer: D

Rationale: The correct first action for the nurse to take when assessing a client with a new diagnosis of Listeria food poisoning is to inquire if the client has consumed any unpasteurized products. This is crucial because Listeria contamination is often associated with unpasteurized dairy products and undercooked meats. Educating the client on safe food practices (Choice A) is important but not the priority at this initial assessment stage. Starting a traceback to identify the source of the outbreak (Choice B) and reporting the case to the county board of health (Choice C) are necessary actions but should come after gathering information directly from the client regarding potential exposure to high-risk foods.

4. A nurse is teaching a client about iron-rich foods. Which food is the best source of heme iron?

• A. Spinach
• B. Lentils
• C. Beef liver
• D. Tofu

Correct answer: C

Rationale: Heme iron, found in animal products like beef liver, is more easily absorbed than non-heme iron from plant sources.

5. Toilet training occurs in the anal stage of Freud’s psychosexual development. This is equivalent to Erikson’s:

• A. Trust vs. Mistrust
• B. Autonomy vs. Shame and Doubt
• C. Initiative vs. Guilt
• D. Industry vs. Inferiority

Correct answer: A

Rationale: The correct answer is A: Trust vs. Mistrust. In Freud's psychosexual development theory, the anal stage is where toilet training occurs, focusing on issues of control and independence. This stage is parallel to Erikson's Trust vs. Mistrust stage, where infants learn to trust or mistrust their caregivers based on the consistency of care they receive. Choices B, C, and D are incorrect as they correspond to different stages in Erikson's psychosocial development theory, not related to toilet training or the anal stage of Freud's theory.
