HESI LPN
HESI PN Nutrition Practice Exam
1. If a group of people consumes an amount of protein equal to the estimated average requirement for their population group, what percentage of people will receive insufficient amounts?
- A. 10
- B. 25
- C. 33
- D. 50
Correct answer: D
Rationale: If a group consumes an amount of protein equal to the estimated average requirement, 50% of the people will receive insufficient amounts. The estimated average requirement is the amount of a nutrient that is estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group. Therefore, 50% of the group will not be meeting their individual needs if they are consuming only the average requirement. Choices A, B, and C are incorrect because at the estimated average requirement level, a higher percentage than those values will receive insufficient amounts.
2. When teaching an adolescent with type 1 diabetes about dietary management, what should the nurse include?
- A. Eating meals at home is recommended.
- B. Food portions should be measured using a gram scale.
- C. Ensure a ready source of glucose is available.
- D. No specific foods need to be cooked for the adolescent.
Correct answer: C
Rationale: When teaching an adolescent with type 1 diabetes about dietary management, it is crucial to ensure a ready source of glucose is available. In cases of hypoglycemia, having a quick source of glucose can help raise blood sugar levels rapidly. Option A is not the most critical aspect of dietary management for an adolescent with type 1 diabetes. While it is generally recommended to eat meals at home for better control over food choices, the availability of a ready glucose source takes precedence. Option B, weighing foods on a gram scale, may not be practical for every meal and could be burdensome. Option D, cooking specific foods for the adolescent, is not necessary as the focus should be on the overall dietary plan rather than individualized meals.
3. Tertiary prevention would best be described as:
- A. recovery from physical limitation and psychological regression
- B. health teaching and immunization
- C. rehabilitation of alcoholic and drug dependents
- D. preventing disability and maximum use of remaining capacity
Correct answer: D
Rationale: Tertiary prevention is the stage of prevention that aims at preventing disability and maximizing the use of remaining capacity. Choice A is more aligned with rehabilitation rather than tertiary prevention. Choice B refers to primary prevention by promoting health and preventing diseases. Choice C focuses on rehabilitation specific to alcohol and drug dependence, which is a form of secondary prevention, not tertiary prevention.
4. The parents of a 2-year-old child tell the nurse that they are having difficulty disciplining their child. What is the nurse’s most appropriate response?
- A. “This is a challenging age for your child right now.”
- B. “Could you elaborate on your challenges? I’m not clear on what you mean.”
- C. “It’s important to be consistent with toddlers when they need discipline.”
- D. “I understand your concern. This phase is often referred to as the 'terrible twos'.”
Correct answer: C
Rationale: The most appropriate response for the nurse is to emphasize the importance of consistency in discipline when dealing with toddlers. Toddlers are at a stage where they are exploring boundaries and learning what behaviors are acceptable. By being consistent, parents can help reinforce these boundaries and teach appropriate behaviors effectively. Choices A, B, and D do not provide specific guidance on how to address the discipline issue effectively. While acknowledging the challenges of this age (Choice A) and empathizing with the parents (Choice D) are important, the key point in this scenario is to highlight the significance of consistency in discipline (Choice C).
5. What is the primary function of hemoglobin in red blood cells?
- A. Oxygen transport
- B. Immunity
- C. Blood clotting
- D. Carbon dioxide transport
Correct answer: A
Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.
