LPN Nutrition Practice Test

1. What is a key dietary consideration for a child with phenylketonuria (PKU)?

Correct answer: B

Rationale: A low-phenylalanine diet is crucial for managing PKU to prevent neurological damage and maintain normal development. Phenylalanine is an amino acid found in protein-containing foods, and individuals with PKU have difficulty metabolizing it. Consuming foods low in phenylalanine helps prevent the buildup of toxic byproducts in the body. Choices A, C, and D are incorrect. A high-fiber diet, increased dairy intake, and high-sodium diet are not specific dietary considerations for PKU management. In fact, dairy products are a source of protein and phenylalanine, which should be limited in PKU.

2. How should a healthcare provider assist in the management of a child with type 1 diabetes?

Correct answer: B

Rationale: For the management of type 1 diabetes in a child, scheduling frequent blood glucose tests is essential. These tests help in monitoring blood sugar levels, adjusting insulin doses, and ensuring proper glucose control. Choices A, C, and D are incorrect. Providing high-carbohydrate snacks can lead to blood sugar spikes, increasing dietary fat intake is not recommended, and encouraging a high-protein diet is not a standard recommendation for managing type 1 diabetes in children.

3. Which measure best describes the amounts of nutrients that should be consumed by the population?

Correct answer: D

Rationale: The Recommended Dietary Allowances (RDAs) are the best measure to describe the amounts of nutrients that should be consumed by the population. RDAs represent the average daily intake level that meets the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage and gender group. Choice A, the Dietary Reference Intakes, provide a set of nutrient intake values but do not specifically address the average daily amount of a nutrient considered adequate for practically all individuals. Choice B, the Tolerable Upper Intake levels, focus on the maximum daily amount of a nutrient deemed safe for most healthy people, not the average daily amount needed. Choice C, the Estimated Average Requirements, reflect the average daily amount of a nutrient needed by half of the healthy individuals, which is not as comprehensive as the RDAs that cater to nearly all healthy people.

4. What is the key to preventing recurrent respiratory infections in children with cystic fibrosis?

Correct answer: B

Rationale: The correct answer is B: Daily chest physiotherapy. Daily chest physiotherapy is essential in cystic fibrosis as it helps in clearing mucus from the lungs, reducing the frequency of respiratory infections. Antibiotics (Choice A) may treat infections but are not the key preventive measure. Increased fluid intake (Choice C) and dietary supplements (Choice D) can be beneficial for overall health but do not directly prevent recurrent respiratory infections in children with cystic fibrosis.

5. What is a common symptom of a respiratory infection in infants?

Correct answer: A

Rationale: Wheezing is a common symptom of respiratory infections in infants, often associated with coughing and difficulty breathing. It occurs due to the narrowing of the airways. Choice B, 'High appetite,' is incorrect as respiratory infections usually lead to a decrease in appetite rather than an increase. Choice C, 'Increased thirst,' is incorrect as it is not a typical symptom of a respiratory infection in infants. Choice D, 'Lethargy,' can be a symptom of respiratory infections but is not as specific and common as wheezing.
