HESI PN Nutrition Practice Exam

1. You have been asked to help a top nutrition researcher conduct human experiments on vitamin C. As the subjects walk into the laboratory, you distribute all the vitamin C pill bottles to the girls and all the placebo pill bottles to the boys. What should you have done?

Correct answer: D

Rationale: The correct approach in a scientific experiment is to prevent yourself from knowing the contents of the pill bottles and distribute them randomly to the subjects. This randomization helps to avoid bias and ensures that the results are not influenced by preconceived notions. Option A is incorrect because it introduces gender bias by assigning pills based on gender. Option B is incorrect as it mentions telling the subjects what they are getting, which could lead to placebo effects. Option C is incorrect as it suggests disclosing group information to the subjects, which can also introduce bias.

2. What is the primary treatment for a child with acute otitis media?

Correct answer: C

Rationale: The correct answer is C: Antibiotics. Antibiotics are the primary treatment for acute otitis media because the condition is often caused by a bacterial infection. Antihistamines (choice A) and nasal decongestants (choice B) are not the primary treatments for acute otitis media as they do not target the bacterial infection. Ear drops (choice D) are not the primary treatment for acute otitis media; antibiotics are required to treat the underlying bacterial cause.

3. Food energy is commonly expressed in kilocalories and in what other unit?

Correct answer: A

Rationale: Food energy is commonly expressed in kilocalories and kilojoules. Kilocalories and kilojoules are both units of energy commonly used to measure the energy content of food. Kilograms, kilometers, and kilonewtons are units of mass, distance, and force, respectively, and are not used to express food energy.

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

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.

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

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.
