HESI LPN
HESI Fundamental Practice Exam
1. The nurse is caring for a client with a nasogastric (NG) tube. Which action should the LPN/LVN take to maintain patency of the tube?
- A. Flush the tube with 30 ml of water before and after medication administration.
- B. Secure the tube to the client's gown.
- C. Check the placement of the tube by auscultation.
- D. Irrigate the tube with normal saline every shift.
Correct answer: A
Rationale: The correct action to maintain patency of a nasogastric (NG) tube is to flush the tube with water before and after medication administration. Flushing helps prevent clogging and ensures that the tube remains clear for proper functioning. Securing the tube to the client's gown (Choice B) is important for stability but does not directly address tube patency. Checking the placement of the tube by auscultation (Choice C) is crucial for verifying correct placement but does not specifically relate to maintaining tube patency. Irrigating the tube with normal saline every shift (Choice D) is not a routine practice for maintaining tube patency and can lead to electrolyte imbalances.
2. A female client with bulimia nervosa is admitted to the hospital. Which intervention should the nurse include in the plan of care?
- A. Allow the client to eat meals alone to reduce stress.
- B. Observe the client for 30 minutes after meals.
- C. Provide the client with a high-calorie diet.
- D. Encourage the client to weigh herself daily.
Correct answer: B
Rationale: The correct intervention for a client with bulimia nervosa is to observe the client for 30 minutes after meals. This helps prevent purging behaviors, such as vomiting or using laxatives, which are common in bulimia nervosa. Choice A is incorrect because eating meals alone may enable the client to engage in purging behaviors without being observed. Choice C is incorrect as a high-calorie diet may exacerbate the client's concerns about weight gain. Choice D is incorrect because encouraging daily weigh-ins can reinforce obsessive thoughts about weight and body image.
3. Which of the following parameters would be LEAST reliable when assessing the perfusion status of a 2-year-old child with possible shock?
- A. distal capillary refill
- B. systolic blood pressure
- C. skin color and temperature
- D. presence of peripheral pulses
Correct answer: B
Rationale: Systolic blood pressure is the least reliable parameter when assessing the perfusion status of a 2-year-old child with possible shock. In pediatric patients, especially young children, blood pressure may not decrease until significant shock has already occurred, making it a late indicator of inadequate perfusion. Depending solely on systolic blood pressure to evaluate perfusion status in this age group can lead to a delay in appropriate interventions. Distal capillary refill time, skin color, and temperature changes, and the presence of peripheral pulses are more sensitive and early indicators of perfusion status in pediatric patients. Monitoring distal capillary refill provides information on peripheral perfusion, while changes in skin color and temperature can signal circulatory compromise. Evaluating the presence or absence of peripheral pulses offers insights into vascular perfusion. These parameters offer more reliable and prompt feedback on a child's perfusion status compared to systolic blood pressure.
4. The nurse is using the CAGE questionnaire as a screening tool for a client who is seeking help because his wife said he had a drinking problem. What information should the nurse explore in depth with the client based on this screening tool?
- A. Cancer screening results, anger, gastritis, daily alcohol intake.
- B. Efforts to cut down, annoyance with questions, guilt, drinking as an 'Eye-opener.'
- C. Consumption, liver enzyme, gastrointestinal complaints and bleeding.
- D. Minimizes drinking, frequently misses family events, guilt about drinking, amount of daily intake.
Correct answer: B
Rationale: The CAGE questionnaire is used to identify problematic drinking behaviors. Choice B is correct because it includes key aspects that the nurse should explore further with the client. 'Efforts to cut down' can indicate acknowledgment of excessive drinking, 'guilt' reflects emotional distress related to drinking, and 'drinking as an 'Eye-opener'' suggests potential dependency. Choices A, C, and D are incorrect as they do not directly address the essential elements assessed by the CAGE questionnaire and may not provide relevant information for further evaluation of the client's drinking habits.
5. The parents of a child with asthma ask the nurse how they can help their child prevent asthma attacks. What should the nurse advise?
- A. Avoid exposure to allergens
- B. Encourage regular exercise
- C. Provide a high-protein diet
- D. Increase fluid intake
Correct answer: A
Rationale: The correct answer is to advise the parents to avoid exposure to allergens. Asthma attacks are often triggered by allergens such as dust mites, pollen, pet dander, and mold. By minimizing the child's exposure to these triggers, the likelihood of asthma attacks can be reduced. Encouraging regular exercise is beneficial for overall health but may not directly prevent asthma attacks. Providing a high-protein diet and increasing fluid intake are important for general well-being but do not specifically address asthma prevention.
