Nutrition HESI Practice Exam

Correct Answer: C

Rationale: The correct answer is C, Peanut butter. While kidney beans, strawberries, and whole wheat bread are high-fiber foods that help alleviate constipation, peanut butter is not a significant source of fiber. Peanut butter is more known for its protein and healthy fats content rather than being a good source of dietary fiber. Therefore, it should not be included as a primary recommendation for a high-fiber diet in the context of addressing constipation.

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: 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: Checking the client's gag reflex is the appropriate action in this scenario. It helps assess the client's ability to swallow safely without the risk of aspiration. Adding a thickening agent to the fluids (Choice A) may be considered later if swallowing difficulties persist. Feeding the client only solid foods (Choice C) can increase the risk of aspiration in this case, and increasing the rate of intravenous fluids (Choice D) does not address the swallowing concern.

Correct Answer: D

Rationale: After the insertion of an enteral feeding tube, the most accurate method for verifying its placement is by aspirating gastric contents. This method ensures that the tube is correctly positioned in the stomach. Abdominal x-ray can provide additional confirmation but is not as immediate or practical. Auscultation and flushing the tube with saline are not as reliable as aspirating gastric contents for verifying proper placement of an enteral feeding tube.
