HESI LPN

Nutrition Final Exam

1. What is the smallest amount of a nutrient that, when consumed over a prolonged period, maintains a specific function?

A. nutrient allowance
B. nutrient requirement
C. nutrient tolerable limit
D. nutrient adequate intake

Correct answer: B

Rationale: The correct answer is 'B: nutrient requirement.' The nutrient requirement refers to the smallest amount of a nutrient that, when consumed over a prolonged period, maintains a specific function in the body. This amount ensures the body's optimal functioning and health. Choice A, 'nutrient allowance,' is incorrect as it does not specifically refer to the minimum amount needed for bodily functions but rather suggests a broader term. Choice C, 'nutrient tolerable limit,' is incorrect as it pertains to the maximum amount of a nutrient that can be consumed without adverse effects. Choice D, 'nutrient adequate intake,' is incorrect as it refers to the recommended average daily intake level of a nutrient to meet the requirements of most healthy individuals.

2. What is the primary symptom of a urinary tract infection in young children?

A. Frequent urination
B. Abdominal pain
C. Vomiting
D. Fever

Correct answer: D

Rationale: The correct answer is D, Fever. In young children, fever is a common primary symptom of a urinary tract infection, often accompanied by irritability and discomfort. Frequent urination (Choice A) is a symptom more commonly seen in adults with UTIs. While abdominal pain (Choice B) and vomiting (Choice C) can be present, they are not as primary as fever in young children with UTIs.

3. Following diarrhea, which foods should be offered to the school-age child?

A. Apricots and peaches
B. Chocolate milk
C. Applesauce and milk
D. Bananas and rice

Correct answer: D

Rationale: After a bout of diarrhea, it is important to offer foods that are gentle on the stomach and help in recovery. Bananas and rice are commonly recommended as they are easily digestible and can help firm up stools. Apricots, peaches, and applesauce may be too acidic and fibrous, potentially aggravating the stomach. Chocolate milk is high in sugar and can worsen diarrhea due to its lactose content.

4. Which statement best describes the relationship between diet and chronic diseases?

A. Diet has no impact on chronic diseases.
B. A poor diet can increase the risk of developing chronic diseases.
C. Diet is the sole cause of chronic diseases.
D. A balanced diet can help prevent or manage chronic diseases.

Correct answer: B

Rationale: Choice B is the correct answer. A poor diet can increase the risk of developing chronic diseases due to the lack of essential nutrients or the presence of harmful components like excessive sugar, salt, or saturated fats. While diet plays a significant role in the development of chronic diseases, it is not the sole cause (choice C). Choice A is incorrect because diet does indeed have a significant impact on chronic diseases. Choice D is not the best answer as it does not acknowledge the negative impact of a poor diet on chronic diseases.

5. Why must a child with acute laryngotracheobronchitis be kept NPO?

A. The epinephrine administration may cause nausea and vomiting
B. The child is being hydrated with IV fluids
C. The child may not feel hungry
D. Rapid respirations pose a risk for aspiration

Correct answer: D

Rationale: In acute laryngotracheobronchitis, rapid respirations increase the risk of aspiration due to compromised airway protection and potential for secretions to enter the lungs. Keeping the child NPO helps prevent the risk of aspiration pneumonia. Choice A is incorrect because epinephrine is not typically used for laryngotracheobronchitis. Choice B is incorrect as hydration with IV fluids does not eliminate the risk of aspiration. Choice C is also incorrect because the child being hungry is not the primary reason for keeping them NPO in this condition.
