1. How should hydration status be assessed in a child with vomiting and diarrhea?

• A. Check skin turgor and mucous membranes
• B. Measure blood glucose levels
• C. Assess heart rate and blood pressure
• D. Evaluate bowel sounds

Correct answer: A

Rationale: Checking skin turgor and mucous membranes is the appropriate method to assess hydration status in a child with vomiting and diarrhea. Skin turgor is an indicator of skin elasticity, which decreases when an individual is dehydrated. Mucous membranes, such as the inside of the mouth, can also show signs of dehydration like dryness. Measuring blood glucose levels (choice B) is not relevant to assessing hydration status in this scenario. Assessing heart rate and blood pressure (choice C) is important in evaluating the overall condition of a child but may not directly indicate hydration status. Evaluating bowel sounds (choice D) is more related to assessing gastrointestinal function rather than hydration status.

2. What is the term for the study of how diet affects gene expression?

• A. Epigenetics
• B. Nutrigenomics
• C. Genomics
• D. Genetics

Correct answer: B

Rationale: Nutrigenomics is the study of how diet affects gene expression, influencing health outcomes and disease risk. Epigenetics (choice A) involves changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence. Genomics (choice C) is the study of an organism's entire genome. Genetics (choice D) is the study of heredity and the variation of inherited characteristics.

3. What is the priority assessment for a child with suspected appendicitis?

• A. Temperature
• B. Heart rate
• C. Respiratory rate
• D. Pain level

Correct answer: D

Rationale: The priority assessment for a child with suspected appendicitis is 'Pain level.' Evaluating the pain level, particularly in the lower right quadrant, is crucial as it helps in determining the severity of the condition, leading to prompt diagnosis and treatment. Monitoring temperature, heart rate, and respiratory rate are important aspects of assessment; however, they are secondary to assessing the pain level in cases of suspected appendicitis. Pain assessment is key in diagnosing this condition since the classic presentation includes abdominal pain that often starts around the umbilicus and then localizes to the right lower quadrant.

4. Which statement is true of minerals in their role as nutrients?

• A. They are organic compounds.
• B. They yield 4 kilocalories per gram.
• C. Some become dissolved in body fluids.
• D. Some are destroyed during cooking.

Correct answer: C

Rationale: The correct statement is that some minerals become dissolved in body fluids, making them available for absorption and utilization by the body. Minerals are not organic compounds, so choice A is incorrect. Choice B is incorrect because minerals do not provide energy like macronutrients such as carbohydrates and fats. Choice D is incorrect because minerals are elements and cannot be destroyed by cooking; however, their availability and absorption may be affected by cooking methods.

5. What is the primary role of dietary guidelines?

• A. To ensure that all food groups are consumed in appropriate proportions.
• B. To prevent chronic diseases and promote overall well-being.
• C. To help individuals meet their nutritional needs while reducing the risk of chronic disease.
• D. To offer specific recommendations for the intake of nutrients that support health.

Correct answer: C

Rationale: The correct answer is C: 'To help individuals meet their nutritional needs while reducing the risk of chronic disease.' Dietary guidelines are designed to provide guidance on the types and amounts of food that support good health and reduce the risk of chronic diseases. Choice A has been corrected to mention 'appropriate proportions' instead of 'equal amounts,' as dietary guidelines emphasize balance and variety. Choice B is partially correct, but the primary focus of dietary guidelines is on meeting nutritional needs. Choice D is incorrect because while dietary guidelines may include nutrient recommendations, their primary focus is on overall dietary patterns rather than specific nutrient intake.
