HESI LPN
HESI Fundamental Practice Exam
1. A healthcare professional is explaining the use of written consent forms to a newly-licensed healthcare professional. The healthcare professional should ensure that a written consent form has been signed by which of the following clients?
- A. A client who has a prescription for a transfusion of packed red blood cells.
- B. A client who is scheduled for a routine physical examination.
- C. A client who is undergoing a minor surgical procedure without anesthesia.
- D. A client who has been prescribed a new medication.
Correct answer: A
Rationale: Correct! Written consent is required for procedures that carry significant risks, such as blood transfusions, to ensure the client’s informed consent and understanding of the procedure. In this case, a transfusion of packed red blood cells is an invasive procedure that carries risks, making it essential to have the client's written consent. Choices B, C, and D do not typically require written consent as routine physical examinations, minor surgical procedures without anesthesia, and new medication prescriptions do not carry the same level of risk and complexity as a blood transfusion.
2. A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hours. The healthcare professional should set the pump to deliver how many mL/hr?
- A. 107 mL/hr
- B. 75 mL/hr
- C. 90 mL/hr
- D. 60 mL/hr
Correct answer: A
Rationale: To calculate the mL/hr rate for the infusion, divide the total volume (750 mL) by the total time (7 hours). 750 mL ÷ 7 hours = 107 mL/hr. This means that the pump should be set to deliver approximately 107 mL/hr. Choice B (75 mL/hr) is incorrect because it does not reflect the correct calculation. Choice C (90 mL/hr) is incorrect as it does not align with the accurate calculation. Choice D (60 mL/hr) is incorrect as it does not match the correct mL/hr rate obtained through the calculation.
3. 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.
4. A healthcare professional is supervising the logrolling of a patient. To which patient is the healthcare professional most likely providing care?
- A. A patient with neck surgery
- B. A patient with hypostatic pneumonia
- C. A patient with a total knee replacement
- D. A patient with a stage IV pressure ulcer
Correct answer: A
Rationale: Logrolling is a technique used to move a patient as a single unit to prevent twisting or bending of the spine. Patients who have undergone neck surgery require special care to ensure the spinal column remains in straight alignment to prevent further injury. Therefore, the correct answer is a patient with neck surgery. Choice B, a patient with hypostatic pneumonia, does not require logrolling, as it is a condition affecting the lungs, not the spine. Choice C, a patient with a total knee replacement, does not typically necessitate logrolling, as the procedure focuses on the knee joint, not the spine. Choice D, a patient with a stage IV pressure ulcer, requires wound care but does not necessarily involve logrolling unless the ulcer is located in a critical area that requires special handling.
5. 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.
