1. This study, which is an in-depth study of one boy, is a:

A. case study
B. longitudinal study
C. cross-sectional study
D. evaluative study

Correct answer: A

Rationale: The correct answer is 'A: case study.' A case study involves an in-depth examination of a single individual, group, or event. In this scenario, focusing on one boy aligns with the definition of a case study. The other options are not applicable: B) A longitudinal study involves following subjects over a period of time, C) A cross-sectional study examines a population at a single point in time, and D) An evaluative study assesses the effectiveness of a program or intervention, which is not the focus of the given scenario.

2. A client is receiving education from a nurse regarding the dietary changes needed for weight loss. Which of the following actions should the nurse perform first?

A. Educate the client about daily caloric requirements.
B. Determine the client’s daily caloric intake.
C. Provide the client with meal planning information.
D. Show the client how to identify the fat content of packaged foods.

Correct answer: B

Rationale: The correct answer is to determine the client’s daily caloric intake first. This step is crucial in understanding the client's current dietary habits and establishing a baseline for creating an effective weight loss plan. Educating the client about daily caloric requirements (Choice A) can only be done effectively after knowing the client's current intake. Providing meal planning information (Choice C) and teaching the client how to identify fat content in foods (Choice D) come after determining the baseline caloric intake to tailor the plan accordingly.

3. Each of the following is a function of the liver except one. Which one is the exception?

A. Regulatory control of nutrients in the bloodstream
B. Conversion of monosaccharides to triglycerides
C. Breakdown of polysaccharide glycogen into glucose
D. Oxidation of digestive end products to provide energy

Correct answer: B

Rationale: The correct answer is B. The liver does not convert monosaccharides to triglycerides; instead, it converts monosaccharides to glucose or glycogen. Choice A is correct because the liver plays a role in regulating the levels of various nutrients in the bloodstream. Choice C is correct as the liver breaks down stored glycogen into glucose to maintain blood sugar levels. Choice D is correct as the liver oxidizes digestive end products to provide energy. Therefore, only choice B is incorrect as the liver does not convert monosaccharides to triglycerides.

4. Which physiologic role does vitamin C play in the body?

A. Transcribing DNA to RNA
B. Absorption and regulation of calcium
C. Protects integrity of cellular membranes
D. Catalyst for synthesis of blood-clotting factors

Correct answer: C

Rationale: Vitamin C plays a crucial role in protecting the integrity of cellular membranes. It is essential for collagen synthesis, which is important for wound healing and maintaining skin, blood vessels, and other tissues. Choice A is incorrect as the transcription of DNA to RNA is facilitated by vitamin A. Choice B is incorrect as calcium absorption and regulation are functions of vitamin D. Choice D is incorrect as vitamin K serves as a catalyst for the synthesis of blood-clotting factors, not vitamin C.

5. Medications that reduce stomach acidity can impair the absorption of _____.

A. calcium
B. iron
C. vitamin D
D. vitamin C

Correct answer: B

Rationale: Reduced stomach acidity impairs the absorption of iron, as an acidic environment is necessary for optimal iron absorption in the stomach. Choices A, C, and D are incorrect as medications that reduce stomach acidity typically do not significantly affect the absorption of calcium, vitamin D, or vitamin C.
