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 a common treatment for a child with moderate to severe eczema?

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.

3. How should a caregiver handle a child with a known peanut allergy?

Correct answer: A

Rationale: Educating on allergen avoidance is the correct approach when dealing with a child who has a known peanut allergy. This helps in managing the allergy effectively and preventing potential allergic reactions. Increasing exposure to peanuts (Choice B) is dangerous and can trigger severe allergic reactions in a child with a peanut allergy. While antihistamines (Choice C) can help alleviate some symptoms, they should not be the primary method of managing a peanut allergy. Suggesting occasional consumption of peanuts (Choice D) is extremely risky and should never be done for a child with a known peanut allergy.

4. How much energy is required to raise the temperature of one kilogram of water by 1°C?

Correct answer: C

Rationale: The correct answer is 1 kilocalorie. This is the amount of energy required to raise the temperature of 1 kilogram of water by 1°C. Choice A (10 calories) and Choice D (10 kilocalories) are incorrect as they do not represent the correct unit of measurement for this specific scenario. Choice B (100 calories) is also incorrect as it overestimates the amount of energy required. The specific heat capacity of water is approximately 1 calorie/gram °C, which means that 1 kilogram (1000 grams) of water requires 1 kilocalorie (1000 calories) to raise its temperature by 1°C.

5. After surgical repair of a cleft palate, what should be used to prevent injury to the suture line?

Correct answer: C

Rationale: The correct answer is C: Syringe. Using a syringe helps in feeding without causing injury to the suture line after cleft palate repair because it avoids direct contact with the suture area. Straws and spoons can potentially put pressure on the suture line, leading to injury. Cups may not provide the necessary control to prevent contact with the suture line, unlike a syringe.
