HESI PN Nutrition Practice Exam
1. By chemical analysis, what nutrient is present in the highest amounts in most foods?
- A. fats
- B. water
- C. proteins
- D. carbohydrates
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.
2. What should be assessed first in a child with suspected head trauma?
- A. Response to verbal stimuli
- B. Pupillary reaction
- C. Skin color
- D. Heart rate
Correct answer: A
Rationale: The correct answer is to assess the response to verbal stimuli first in a child with suspected head trauma. This assessment helps in determining the child's level of consciousness and neurological status. Assessing the response to verbal stimuli allows healthcare providers to quickly evaluate if the child is alert, oriented, and able to communicate effectively. This initial assessment is crucial in identifying any immediate concerns related to the child's neurological function. Choices B, C, and D are not the primary assessments in cases of suspected head trauma. While pupillary reaction, skin color, and heart rate are important assessments in trauma situations, assessing the response to verbal stimuli takes precedence in evaluating the neurological status of a child with head trauma.
3. What role do fats play in the human body?
- A. They provide a concentrated source of energy.
- B. They are the building blocks of enzymes and hormones.
- C. They are essential for brain function and development.
- D. They aid in the digestion of food.
Correct answer: D
Rationale: Fats play various essential roles in the human body, one of which is aiding in the digestion of food. While fats do provide a concentrated source of energy, the primary source is carbohydrates. Proteins are the building blocks of enzymes and hormones, not fats. Essential fatty acids found in fats are vital for brain function and development, but this is not the primary role of fats in the body.
4. 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?
- A. Giving all the boys the vitamin C and the girls the placebo, and telling them what they were getting.
- B. Distributing the bottles randomly, randomizing the subjects, and telling them what they were getting.
- C. Telling the subjects which group they were in, but preventing yourself from knowing the contents of the pill bottles.
- D. Preventing yourself from knowing what is in the pill bottles, and distributing the bottles randomly to the subjects.
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.
5. What should the nurse anticipate as challenging in caring for a child with acute glomerulonephritis?
- A. Forced fluids
- B. Increased feedings
- C. Bed rest
- D. Frequent position changes
Correct answer: C
Rationale: The correct answer is C: Bed rest. Implementing bed rest can be challenging, especially in active children, but it's necessary to manage the symptoms of acute glomerulonephritis. Forced fluids (choice A) may be required to maintain hydration but are not typically challenging. Increased feedings (choice B) and frequent position changes (choice D) are not primary interventions in the care of a child with acute glomerulonephritis.
