HESI LPN
Practice HESI Fundamentals Exam
1. A client on a telemetry unit is being cared for by a nurse after a myocardial infarction. The client expresses, 'All this equipment is making me nervous.' Which of the following responses should the nurse make?
- A. 'All of this equipment can be frightening.'
- B. 'The equipment is necessary to monitor your condition.'
- C. 'You should try to ignore the equipment.'
- D. 'Try to relax; the equipment is not harmful.'
Correct answer: A
Rationale: Choice A is the most appropriate response as it acknowledges the client's feelings, showing empathy and understanding. It validates the client's experience, which can help reduce anxiety and build rapport. Choice B provides information but may not address the client's emotional needs. Choice C dismisses the client's concerns and does not offer support. Choice D minimizes the client's feelings and may not effectively address their anxiety.
2. When assessing a client with wrist restraints, the nurse observes that the fingers on the right hand are blue. What action should the nurse implement first?
- A. Loosen the right wrist restraint.
- B. Apply a pulse oximeter to the right hand.
- C. Compare hand color bilaterally.
- D. Palpate the right radial pulse.
Correct answer: A
Rationale: The correct action to take first when observing blue fingers in a client with wrist restraints is to loosen the right wrist restraint. Blue fingers indicate compromised circulation, and loosening the restraint can help restore blood flow to the area. Applying a pulse oximeter (Choice B) or palpating the right radial pulse (Choice D) may be necessary following the loosening of the restraint to assess the client's oxygen saturation and pulse. Comparing hand color bilaterally (Choice C) is important but not the immediate action needed when a circulation issue is noted in one hand.
3. A nurse working on an endocrine unit should see which client first?
- A. An adolescent male with diabetes who is arguing about his insulin dose.
- B. An older client with Addison’s disease whose current blood sugar level is 62mg/dl (3.44 mmol/l).
- C. An adult with a blood sugar of 384mg/dl (21.31mmol/l) and urine output of 350 ml in the last hour.
- D. A client taking corticosteroids who has become disoriented in the last two hours.
Correct answer: B
Rationale: The correct answer is B. The client with Addison’s disease and a blood sugar level of 62mg/dl (3.44 mmol/l) is experiencing hypoglycemia, which can progress to adrenal crisis. This situation requires immediate attention to prevent further complications. Choices A, C, and D, although concerning, do not pose an immediate life-threatening risk compared to the client with Addison’s disease and hypoglycemia. The adolescent arguing about his insulin dose can be addressed after stabilizing the client with Addison’s disease. The adult with high blood sugar and increased urine output may have hyperglycemia but is not in immediate danger. The client taking corticosteroids who is disoriented needs evaluation but is not in an acute life-threatening condition as the client with hypoglycemia.
4. A client is receiving metronidazole for Clostridium difficile pseudomembranous colitis. Which information should the nurse include in this client's medication teaching plan?
- A. Drink adequate water daily
- B. Take with food
- C. Avoid alcohol consumption
- D. Store medication in the refrigerator
Correct answer: C
Rationale: The correct information to include in the medication teaching plan for a client receiving metronidazole for Clostridium difficile pseudomembranous colitis is to avoid alcohol consumption. Metronidazole can cause a disulfiram-like reaction when combined with alcohol, leading to symptoms such as nausea, vomiting, flushing, and headache. Therefore, it is crucial for the client to abstain from alcohol while taking this medication to prevent adverse effects and ensure treatment effectiveness. Choices A, B, and D are incorrect. Drinking adequate water daily is a general health recommendation but not specific to metronidazole use. Taking with food is not necessary for metronidazole, and in fact, it is recommended to be taken on an empty stomach for better absorption. Storing the medication in the refrigerator is also incorrect, as metronidazole should be stored at room temperature.
5. The PN administered darbepoetin alfa to a client with chronic kidney disease (CKD). Which serum laboratory value should the PN monitor to assess the effectiveness of this drug?
- A. Calcium
- B. Phosphorus
- C. Hemoglobin
- D. White blood cell count
Correct answer: C
Rationale: Darbepoetin alfa is used to stimulate red blood cell production in clients with CKD. Monitoring hemoglobin levels is essential to assess the effectiveness of the treatment and to adjust the dosage to avoid complications such as hypertension or thrombosis. Monitoring calcium (Choice A), phosphorus (Choice B), or white blood cell count (Choice D) is not directly related to the effectiveness of darbepoetin alfa in treating anemia associated with CKD.
