Nutrition Final Exam Quizlet

1. Which statement best describes the composition of most foods?

A. Most foods contain a mixture of the three energy nutrients, with one or two predominating.
B. Foods do not typically contain equal amounts of the three energy nutrients.
C. Most foods contain mixtures of the three energy nutrients, although only one or two may predominate.
D. Most foods contain all three energy nutrients in varying amounts.

Correct answer: C

Rationale: The correct answer is C. Most foods contain a mixture of the three energy nutrients (carbohydrates, proteins, fats), with one or two predominating. Choice A is correct because most foods do contain a combination of energy nutrients, with one or two types usually being predominant. Choice B is incorrect as foods typically do not contain equal amounts of carbohydrates, proteins, and fats. Choice D is incorrect because most foods contain all three energy nutrients, not just one or two types.

2. What intervention is recommended for a child with severe dehydration?

A. Oral rehydration therapy
B. Intravenous fluid replacement
C. High-protein diet
D. Increased physical activity

Correct answer: B

Rationale: Intravenous fluid replacement is the recommended intervention for a child with severe dehydration because it allows for rapid restoration of fluid and electrolyte balance. In severe cases, oral rehydration therapy (Choice A) may not be tolerated due to the child's condition. A high-protein diet (Choice C) is not the primary intervention and does not address the immediate fluid and electrolyte imbalance. Increased physical activity (Choice D) is contraindicated in severe dehydration as it can exacerbate fluid loss, making intravenous fluid replacement the most suitable choice for prompt correction of the severe dehydration.

3. What is the appropriate intervention for a child with an undescended testicle?

A. Wait until puberty
B. Perform an orchidopexy
C. Administer hormone therapy
D. Increase physical activity

Correct answer: B

Rationale: The appropriate intervention for a child with an undescended testicle is to perform an orchidopexy. This surgical procedure is recommended if the testicle has not descended naturally within the first year of life. Waiting until puberty is not advised as early intervention is crucial for optimal outcomes. Administering hormone therapy is not the first-line treatment for an undescended testicle and is typically not recommended. Increasing physical activity does not address the underlying issue of an undescended testicle and is not a suitable intervention.

4. What is the primary treatment for a child with an anaphylactic reaction?

A. Oral antihistamines
B. Intravenous fluids
C. Epinephrine injection
D. Antipyretics

Correct answer: C

Rationale: The correct answer is C: Epinephrine injection. An epinephrine injection is the primary treatment for an anaphylactic reaction in children. Epinephrine acts quickly to reverse severe symptoms such as difficulty breathing, low blood pressure, and hives. Oral antihistamines, although useful for milder allergic reactions, are not sufficient to manage the potentially life-threatening symptoms of anaphylaxis. Intravenous fluids may be necessary to support blood pressure in a child with anaphylaxis but are not the primary treatment. Antipyretics, on the other hand, are medications used to reduce fever and are not indicated as the primary treatment for an anaphylactic reaction.

5. How should hydration status in a child with fever and vomiting be assessed?

A. Monitor skin turgor and mucous membranes
B. Measure blood glucose levels
C. Check for signs of jaundice
D. Assess respiratory rate

Correct answer: A

Rationale: To assess hydration status in a child with fever and vomiting, monitoring skin turgor and mucous membranes is essential. Skin turgor refers to the skin's ability to change shape and return to normal; poor skin turgor can indicate dehydration. Mucous membranes, such as the mouth and eyes, can also provide valuable information about hydration levels. Measuring blood glucose levels (Choice B) is not directly related to assessing hydration status. Checking for signs of jaundice (Choice C) is important for liver-related issues, not hydration assessment. Assessing respiratory rate (Choice D) is crucial for evaluating respiratory function, not hydration status.
