HESI LPN
HESI Fundamental Practice Exam
1. When orienting a newly licensed nurse on taking a telephone prescription, which statement indicates understanding of the process?
- A. A second nurse enters the prescription into the client’s medical record.
- B. Another nurse should listen to the phone call.
- C. The provider can clarify the prescription when they sign the health record.
- D. I should omit the 'read back' if this is a one-time prescription.
Correct answer: A
Rationale: The correct answer is A because a second nurse should verify and enter the prescription into the client’s medical record to ensure accuracy. This step is crucial to prevent errors in transcription and administration. Choice B is incorrect as having another nurse listen to the phone call does not ensure accurate transcription. Choice C is incorrect because the provider clarifying the prescription upon signing the health record does not replace the need for proper documentation. Choice D is incorrect because the 'read back' process is essential for all telephone prescriptions to confirm accuracy and prevent errors in transcription or administration.
2. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?
- A. 13 ml/hour
- B. 63 ml/hour
- C. 80 ml/hour
- D. 125 ml/hour
Correct answer: B
Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.
3. The client is learning about lifestyle changes to manage hypertension. Which statement by the client requires further teaching?
- A. I will reduce my salt intake.
- B. I will exercise for 30 minutes most days of the week.
- C. I will drink alcohol only on the weekends.
- D. I will monitor my blood pressure regularly.
Correct answer: C
Rationale: The correct answer is C. Clients with hypertension should ideally avoid or limit alcohol intake rather than just restricting it to weekends. Excessive alcohol consumption can raise blood pressure and interfere with the effectiveness of hypertension management. Choices A, B, and D are all positive statements that align with managing hypertension: reducing salt intake, regular exercise, and monitoring blood pressure are all beneficial lifestyle changes for individuals with hypertension. Therefore, the statement about drinking alcohol only on weekends requires further teaching to emphasize the importance of reducing alcohol consumption for better blood pressure control.
4. The healthcare professional prepares a 1,000 ml IV of 5% dextrose and water to be infused over 8 hours. The infusion set delivers 10 drops per milliliter. The healthcare professional should regulate the IV to administer approximately how many drops per minute?
- A. 80
- B. 8
- C. 21
- D. 25
Correct answer: C
Rationale: To calculate the drops per minute for the IV infusion, first determine the total drops to be infused over 8 hours. 1,000 ml to be infused over 8 hours means 125 ml per hour (1000 ml / 8 hours = 125 ml/hr). Since the infusion set delivers 10 drops per ml, 125 ml/hr x 10 drops/ml = 1250 drops/hr. To find drops per minute, divide the drops per hour by 60 (minutes in an hour): 1250 drops/hr / 60 minutes = 20.83 drops/minute, which rounds up to 21 drops per minute (Option C). This rate ensures the correct infusion rate over 8 hours. Choices A, B, and D are incorrect calculations and do not provide the appropriate infusion rate needed to administer the IV over the specified time period.
5. A nurse is precepting a newly licensed nurse who is preparing to help a client perform tracheostomy care. The nurse should intervene if the equipment the preceptee gathered included:
- A. Cotton balls
- B. Sterile gloves
- C. A suction catheter
- D. Tracheostomy tubes
Correct answer: A
Rationale: The correct answer is A: Cotton balls. Cotton balls are not suitable for tracheostomy care due to the risk of lint and contamination. When performing tracheostomy care, sterile supplies such as sterile gloves, a suction catheter, and tracheostomy tubes are essential. Sterile gloves are needed to maintain asepsis, a suction catheter is necessary for airway clearance, and tracheostomy tubes are crucial for maintaining a patent airway. Cotton balls should be avoided to prevent introducing lint or fibers into the tracheostomy site, which can lead to infection or airway obstruction.
