HESI LPN
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. A client's daughter phones the charge nurse to report that the night nurse did not provide good care for her mother. What response should the nurse make?
- A. Explain that all staff are doing their best
- B. Ask for a description of what happened during the night
- C. Tell the daughter to talk to the unit's nurse manager
- D. Reassure the daughter that the mother will get better care
Correct answer: B
Rationale: The correct response for the nurse in this situation is to ask for a description of what happened during the night. This allows the nurse to gather specific information about the care provided and address the complaint appropriately. Choice A is incorrect because dismissing the concern by stating that all staff are doing their best does not address the specific complaint. Choice C is not the best immediate response as the charge nurse should first gather information before escalating the issue to the nurse manager. Choice D is incorrect as it focuses on reassurance without addressing the reported issue.
3. A child with a diagnosis of cystic fibrosis is admitted to the hospital. What is the priority nursing intervention?
- A. Administering pancreatic enzymes
- B. Providing respiratory therapy
- C. Providing nutritional support
- D. Encouraging physical activity
Correct answer: A
Rationale: The correct answer is administering pancreatic enzymes. In cystic fibrosis, the pancreas is often affected, leading to insufficient production of digestive enzymes. Administering pancreatic enzymes is crucial to ensure proper digestion and absorption of nutrients. While respiratory therapy, nutritional support, and physical activity are essential components of care for individuals with cystic fibrosis, addressing the digestive aspect by administering pancreatic enzymes takes priority to prevent malnutrition and promote overall health.
4. After adding feeding solution to a client's tube feeding system as seen in the picture, what action should the PN take next?
- A. Remove the air from the solution bag
- B. Obtain a piston syringe and irrigation set
- C. Record the solution added as fluid intake
- D. Calculate the rate of flow of the solution
Correct answer: B
Rationale: After adding feeding solution, obtaining a piston syringe and irrigation set is necessary to flush the feeding tube and ensure patency before starting the feeding. This helps prevent blockages and ensures proper delivery of the nutritional solution. Option A is incorrect because removing air from the solution bag is not the immediate next step after adding the feeding solution. Option C is incorrect as recording the solution added as fluid intake is important but not the immediate next step. Option D is incorrect as calculating the rate of flow of the solution is not the next step after adding the feeding solution.
5. The nurse is caring for a client with a diagnosis of bipolar disorder who is taking lithium. What is the most important information the nurse should provide?
- A. Take the medication on an empty stomach.
- B. Monitor sodium intake.
- C. Report any signs of weight gain.
- D. Avoid excessive caffeine intake.
Correct answer: B
Rationale: The correct answer is B: 'Monitor sodium intake.' Sodium levels can affect lithium levels in the body, so it is crucial to maintain a consistent sodium intake to prevent toxicity or subtherapeutic levels. Option A is incorrect because lithium is usually recommended to be taken on an empty stomach to enhance absorption. Option C, reporting signs of weight gain, is relevant but not as critical as monitoring sodium intake. Option D, avoiding excessive caffeine intake, is important for some individuals but not as essential as monitoring sodium levels when taking lithium.
