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. How should a healthcare provider respond to a parent concerned about their child's recurrent ear infections?

A. Suggest regular use of over-the-counter ear drops
B. Recommend a thorough evaluation by an ENT specialist
C. Advise on increased antibiotic use
D. Encourage avoiding all physical activities

Correct answer: B

Rationale: When a parent expresses concerns about their child's recurrent ear infections, the best course of action is to recommend a thorough evaluation by an Ear, Nose, and Throat (ENT) specialist. This specialist can conduct a comprehensive assessment to identify the underlying cause of the ear infections and provide appropriate treatment options. Choice A is incorrect because suggesting over-the-counter ear drops without a proper evaluation may not address the root cause of the issue. Choice C is also incorrect as increasing antibiotic use without understanding the specific cause can lead to antibiotic resistance and may not be necessary. Choice D is incorrect as avoiding physical activities is unrelated to addressing recurrent ear infections and is not a recommended approach.

3. How should pain be assessed in a nonverbal child?

A. Ask the parents about the child’s usual behavior
B. Observe the child’s facial expressions and body movements
C. Measure the child’s blood pressure
D. Use a pain rating scale for older children

Correct answer: B

Rationale: Observing the nonverbal child's facial expressions and body movements is crucial in assessing pain. Nonverbal children may not be able to communicate their discomfort verbally, making it essential to rely on physical cues. Asking parents about the child's usual behavior (choice A) may provide some insight but observing the child directly is more direct and reliable. Measuring blood pressure (choice C) is not typically a direct method for assessing pain in nonverbal children. Using a pain rating scale designed for older children (choice D) is also inappropriate for nonverbal children who cannot participate in such self-reporting tools.

4. What is a key preventive measure for avoiding urinary tract infections (UTIs) in children?

A. Restrict fluid intake
B. Encourage frequent urination
C. Use topical antibiotics
D. Increase dietary calcium

Correct answer: B

Rationale: Encouraging frequent urination is a key preventive measure for avoiding urinary tract infections (UTIs) in children. It helps flush bacteria from the urinary tract, reducing the risk of UTIs. Restricting fluid intake (Choice A) is not recommended as it may lead to concentrated urine and increase the risk of UTIs. Using topical antibiotics (Choice C) is not a preventive measure for UTIs and should only be used under medical guidance. Increasing dietary calcium (Choice D) is not directly linked to preventing UTIs in children.

5. Which nutrient is an example of a macronutrient?

A. proteins
B. minerals
C. water-soluble vitamins
D. fat-soluble vitamins

Correct answer: A

Rationale: Proteins are indeed macronutrients as they are required by the body in larger quantities for various functions such as growth, repair, and energy production. Choice B, minerals, are micronutrients needed in smaller amounts for various physiological processes. Choices C and D, water-soluble vitamins and fat-soluble vitamins, respectively, are also micronutrients that play essential roles in the body but are not classified as macronutrients.
