Nutrition HESI Practice Exam

Correct Answer: A

Rationale: Instructing the client to avoid caffeine for 8 hours before the EEG is essential. This intervention helps ensure accurate test results by preventing stimulation of the nervous system, which could interfere with the interpretation of the brain's electrical activity. Explaining the procedure and obtaining consent are important steps but do not directly impact the test results. Administering anticonvulsant medication as ordered is a medical intervention and not a preparation step for the test. Instructing the client to wash their hair the morning of the test is not necessary for EEG preparation.

Correct Answer: B

Rationale: The correct answer is B because a positive acid-fast bacillus smear in an elderly factory worker suggests tuberculosis, a serious communicable disease that must be reported promptly to the public health department to prevent its spread. Choice A is incorrect as Shigella is an important pathogen, but it does not require immediate public health reporting. Choice C is incorrect because Pneumocystis carinii is an opportunistic pathogen and does not require urgent public health reporting. Choice D is incorrect as varicella-zoster virus causes chickenpox and shingles, both of which are not reportable diseases to the public health department.

Correct Answer: D

Rationale: Increasing fluids during meals does not directly contribute to increasing caloric intake. Topping yogurt with granola, using honey on toast, and using milk instead of water in recipes are effective ways to boost caloric intake. While adequate fluid intake is important for hydration and overall health, it does not address the specific need to increase caloric intake in this scenario.

Correct Answer: A

Rationale: The correct answer is A, Tomato juice. Tomato juice is high in vitamin C, which enhances the absorption of nonheme iron from foods. Vitamin C helps convert nonheme iron to a form that is easier for the body to absorb. Tea (choice B) contains tannins that can inhibit iron absorption. Milk (choice C) contains calcium, which can interfere with iron absorption. Dried beans (choice D) are a good source of nonheme iron but do not enhance iron absorption when consumed with nonheme iron.

Correct Answer: C

Rationale: The correct answer is C: Beans. Beans are an excellent choice for individuals following a low-cholesterol diet post-coronary artery bypass grafting due to their low cholesterol content. Beans are high in fiber and protein, making them a heart-healthy option. Choice A, Liver, is high in cholesterol and should be avoided in a low-cholesterol diet. Choice B, Milk, contains cholesterol and saturated fats, which are not ideal for this diet. Choice D, Eggs, are also high in cholesterol and should be limited in a low-cholesterol diet.
