2. A nurse is instructing a group of clients about nutrition. The nurse should include that which of the following is a trigger for the formation of vitamin D in the body?
- A. Calcium
- B. Vitamin A depletion
- C. Exposure to sunlight
- D. Weight-bearing exercise
Correct answer: C
Rationale: Exposure to sunlight is the trigger for the formation of vitamin D in the body. When the skin is exposed to sunlight, it produces vitamin D. This process is essential for maintaining healthy levels of vitamin D in the body. Calcium (Choice A) is important for bone health but is not the trigger for vitamin D formation. Vitamin A depletion (Choice B) does not directly trigger the formation of vitamin D. Weight-bearing exercise (Choice D) is crucial for bone health but is not directly related to the formation of vitamin D.
3. Why do older adult female clients need less iron than younger adult female clients?
- A. The need for iron decreases because older female clients produce more red blood cells.
- B. The need for iron decreases with age because older female clients carry oxygen more efficiently.
- C. The need for iron decreases with age because older female clients experience menopause.
- D. The need for iron decreases with age because older female clients exercise more.
Correct answer: C
Rationale: The correct answer is C. Older adult female clients need less iron than younger adult female clients because as women go through menopause, they no longer lose blood through menstruation, leading to a reduced need for iron. Choice A is incorrect because producing more red blood cells does not directly correlate with needing less iron. Choice B is incorrect as carrying oxygen more efficiently does not necessarily decrease the need for iron. Choice D is incorrect as exercising more does not explain the decreased need for iron in older adult female clients.
4. How is an ear infection that persists for less than 14 days classified?
- A. Mastoiditis
- B. Chronic Ear Infection
- C. Acute Ear Infection
- D. Otitis Media
Correct answer: C
Rationale: Acute Ear Infection is the correct answer because it typically refers to an infection that is short-lived and often severe, typically lasting less than 14 days. Chronic Ear Infection (Choice B) is incorrect as it refers to an ear infection that lasts for a long time or recurs often, typically more than three months. Mastoiditis (Choice A) is a complication of a middle ear infection and not an ear infection itself. Otitis Media (Choice D) is a general term for inflammation or infection in the middle ear, which can be either acute or chronic, so it's not specific enough to be the correct answer. Understanding the duration and severity of symptoms can help in identifying the type of ear infection, facilitating appropriate treatment and prevention of complications.
5. 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.
