LPN Nutrition Practice Test
1. What is the main purpose of Recommended Dietary Allowances (RDAs)?
- A. To provide guidelines for nutrient intakes that meet the needs of most healthy people.
- B. To specify the minimum amount of nutrients required for survival.
- C. To establish maximum safe levels of nutrient intakes.
- D. To recommend specific nutrient intake levels to prevent chronic diseases.
Correct answer: A
Rationale: The main purpose of Recommended Dietary Allowances (RDAs) is to provide guidelines for nutrient intakes that meet the needs of most healthy people. Choice B is incorrect because RDAs aim beyond just survival requirements. Choice C is incorrect because establishing maximum safe levels is the role of Tolerable Upper Intake Levels (ULs). Choice D is incorrect because preventing chronic diseases is more associated with Dietary Reference Intakes (DRIs) like Adequate Intakes (AIs) and Tolerable Upper Intake Levels (ULs). Therefore, the correct answer is A.
2. A healthcare professional is planning care to improve self-feeding for a client with vision loss. Which of the following interventions should the healthcare professional include in the plan of care?
- A. Instruct the client on the sequence of foods to eat first
- B. Offer small-handle utensils for the client to use
- C. Thicken liquids served to the client
- D. Use a clock pattern to indicate food placement on the client's plate
Correct answer: D
Rationale: The correct answer is D. When a client has vision loss, using a clock pattern to describe food placement on the plate can facilitate independent eating. This method enables the client to locate different food items based on their positions, enhancing self-feeding abilities. Instructing the client on the sequence of foods to eat first (Choice A) may not address the visual impairment directly. Providing small-handle utensils (Choice B) can be helpful for clients with limited dexterity but may not specifically assist a client with vision loss. Thickening liquids (Choice C) is more relevant for clients with dysphagia, not vision loss.
3. A 2-year-old child is admitted to the hospital with a diagnosis of Kawasaki disease. What is the primary goal of therapy during the acute phase?
- A. Preventing coronary artery aneurysms
- B. Reducing fever
- C. Improving cardiac function
- D. Preventing dehydration
Correct answer: A
Rationale: The primary goal of therapy during the acute phase of Kawasaki disease is to prevent coronary artery aneurysms, which are a serious complication of this condition. Coronary artery aneurysms can lead to long-term cardiovascular issues, making prevention crucial. While reducing fever and improving cardiac function are important aspects of managing Kawasaki disease, the primary focus in the acute phase is on preventing coronary artery aneurysms. Dehydration prevention is also essential but not the primary goal during the acute phase of this disease.
4. The nurse is counseling a young couple who in 2 months are having their third baby. The nurse uses Von Bertalanffy's general system theory applied to families to analyze the family structure. Which best describes the main emphasis of this theory and its application to family dynamics?
- A. It emphasizes the family as a system with interdependent, interacting parts that endure over time to ensure the survival, continuity, and growth of its components.
- B. It emphasizes the social system of the family, such as the organization or structure of the family and how the structure relates to its function.
- C. It emphasizes the developmental stages that all families go through, beginning with marriage; the longitudinal career of the family is also known as the family life cycle.
- D. It addresses how families respond to stress and how the family copes with stress as a group and how each individual member copes.
Correct answer: A
Rationale: Von Bertalanffy's general system theory applied to families emphasizes the family as a system with interdependent, interacting parts that endure over time to ensure the survival, continuity, and growth of its components. This theory focuses on viewing the family as a dynamic system where each member's actions and behaviors impact the whole family unit. Choice B is incorrect as it focuses solely on the social system of the family, while Von Bertalanffy's theory looks at the family as a whole system. Choice C is incorrect as it discusses family developmental stages, which is not the main emphasis of Von Bertalanffy's theory. Choice D is also incorrect as it only addresses how families respond to stress, which is a narrower focus compared to the broader system view of Von Bertalanffy's theory.
5. The healthcare provider believes that a client who frequently requests pain medication may have a substance abuse problem. Which intervention reflects the healthcare provider's value of client autonomy over veracity?
- A. Administer the prescribed analgesic when requested
- B. Refer the client to a substance abuse program
- C. Collaborate with the healthcare provider to provide a placebo
- D. Document the frequency of medication requests
Correct answer: A
Rationale: Administering the prescribed analgesic when requested is the most appropriate intervention that reflects the healthcare provider's value of client autonomy over veracity. This action respects the client's right to manage their pain and avoids deception. Referring the client to a substance abuse program (Choice B) assumes a diagnosis without evidence and does not respect the client's autonomy. Collaborating to provide a placebo (Choice C) would involve deception, which goes against the value of veracity. Documenting the frequency of medication requests (Choice D) is important for the client's care but does not directly address the issue of respecting client autonomy over veracity.
