LPN Nutrition Practice Test

1. Which of the following is considered a micronutrient?

A. Protein
B. Carbohydrate
C. Vitamin C
D. Fat

Correct answer: C

Rationale: Corrected Question: Vitamin C is considered a micronutrient because it is required in small amounts for proper body functioning and is essential for health. Proteins, carbohydrates, and fats are macronutrients, needed in larger quantities for energy and other body functions. Vitamin C, being a micronutrient, plays a crucial role in various bodily functions even though it is needed in smaller quantities compared to macronutrients. Therefore, the correct answer is C. Choice A (Protein), Choice B (Carbohydrate), and Choice D (Fat) are incorrect as they are macronutrients required in larger amounts for energy and other body functions.

2. What is a common clinical manifestation of Kawasaki disease?

A. Severe headaches
B. High fever lasting more than 5 days
C. Chronic cough
D. Severe abdominal pain

Correct answer: B

Rationale: A high fever lasting more than 5 days is a common clinical manifestation of Kawasaki disease. This fever is often accompanied by other symptoms such as rash and conjunctivitis. Severe headaches (Choice A), chronic cough (Choice C), and severe abdominal pain (Choice D) are not typically associated with Kawasaki disease, making them incorrect choices.

3. What is a common symptom of Kawasaki disease?

A. Persistent fever for more than 5 days
B. Excessive vomiting
C. Sudden weight gain
D. Decreased appetite

Correct answer: A

Rationale: The correct answer is A. Persistent fever lasting more than 5 days is a hallmark symptom of Kawasaki disease, often accompanied by rash and conjunctivitis. Excessive vomiting (choice B), sudden weight gain (choice C), and decreased appetite (choice D) are not typically associated with Kawasaki disease. Therefore, choices B, C, and D can be eliminated as they do not align with the common symptoms of Kawasaki disease.

4. How should a healthcare professional manage a child with scabies?

A. Use topical permethrin cream
B. Administer oral antibiotics
C. Apply topical antifungals
D. Provide supportive care only

Correct answer: A

Rationale: Corrected Rationale: Topical permethrin cream is the appropriate treatment for scabies as it effectively kills the mites causing the infestation. Oral antibiotics are not indicated for scabies as it is not a bacterial infection. Topical antifungals are used to treat fungal infections, not scabies. Providing supportive care only would not address the underlying cause of scabies, which is the mite infestation.

5. What role do fats play in the human body?

A. They provide a concentrated source of energy.
B. They are the building blocks of enzymes and hormones.
C. They are essential for brain function and development.
D. They aid in the digestion of food.

Correct answer: D

Rationale: Fats play various essential roles in the human body, one of which is aiding in the digestion of food. While fats do provide a concentrated source of energy, the primary source is carbohydrates. Proteins are the building blocks of enzymes and hormones, not fats. Essential fatty acids found in fats are vital for brain function and development, but this is not the primary role of fats in the body.
