HESI PN Nutrition Practice Exam

Correct Answer: B

Rationale: Skin rash or hives are common signs of an allergic reaction in children, often following exposure to allergens. While a persistent cough can occur in some cases, it is not typically a primary sign of an allergic reaction. Increased appetite is unrelated to allergic reactions. A low-grade fever is not a common sign of an allergic reaction but can be present in other conditions like infections.

Correct Answer: B

Rationale: When a child is newly diagnosed with a hearing impairment, it is essential to refer them for audiologic evaluation and intervention. This step is crucial to accurately assess the extent of the impairment, determine appropriate interventions, and support the child's communication and development. Increasing the volume of all auditory stimuli (choice A) is not a recommended approach as it may not address the specific needs of the child and could potentially cause discomfort. Avoiding the use of assistive devices (choice C) can hinder the child's ability to communicate effectively. Encouraging frequent use of headphones (choice D) is also not advisable as it may not be suitable for managing hearing impairments and could potentially worsen the condition.

Correct Answer: B

Rationale: The correct answer is B. Water is the most abundant nutrient in many foods. Water content varies across different foods, but in general, it is present in the highest amounts. Fats (Choice A) are essential but are not found in higher amounts compared to water. Proteins (Choice C) and carbohydrates (Choice D) are also important nutrients, but they are typically found in lower quantities in most foods compared to water.

Correct Answer: C

Rationale: The correct statement is that some minerals become dissolved in body fluids, making them available for absorption and utilization by the body. Minerals are not organic compounds, so choice A is incorrect. Choice B is incorrect because minerals do not provide energy like macronutrients such as carbohydrates and fats. Choice D is incorrect because minerals are elements and cannot be destroyed by cooking; however, their availability and absorption may be affected by cooking methods.

Correct Answer: A

Rationale: Topical corticosteroids are the correct answer for a child with moderate to severe eczema. These medications are commonly used to reduce inflammation and itching associated with eczema. Oral antibiotics (Choice B) are not typically used in eczema treatment unless there is a secondary bacterial infection. Frequent saline irrigation (Choice C) may aid in wound care but is not a primary treatment for eczema. A high-calcium diet (Choice D) is not a standard treatment for eczema and does not target the underlying inflammatory process that causes eczema symptoms.
