HESI LPN
HESI Fundamentals Exam Questions
Question 1 of 5
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?
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.
Question 2 of 5
When developing a plan of care for a client with dementia, what should the LPN/LVN remember about confusion in the elderly?
Correct Answer: B
Rationale: When caring for a client with dementia, it is crucial to understand that confusion often arises after relocating to new surroundings. This change can disrupt familiar routines and trigger increased disorientation and confusion. Choice A is correct because confusion in the elderly is not a normal part of aging. Choice C is incorrect because confusion in dementia is primarily due to changes in the brain associated with the disease, not just irreversible brain pathology. Choice D is incorrect because while adequate sleep is important for overall health, it alone cannot prevent or cure confusion associated with dementia.
Question 3 of 5
How can the LPN/LVN best handle the situation of a postoperative client being kept awake by a neighboring client with dementia who sings all night?
Correct Answer: D
Rationale: The best way to handle the situation in this scenario is to move the neighboring client to a room at the end of the hall. This solution is considerate to both clients because it addresses the issue by providing a quieter environment for the client with dementia while allowing the postoperative client to rest. Choice A is inappropriate as it does not address the root cause of the problem and may not be feasible or respectful. Choice B of closing the doors may not effectively reduce the noise disturbance. Choice C of giving the complaining client sedatives should be the last resort and not the initial solution, as it does not address the underlying issue causing the disturbance.
Question 4 of 5
After abdominal surgery, a client has not urinated since the urinary catheter was removed 8 hours ago. What action should the LPN take first?
Correct Answer: A
Rationale: Performing a bladder scan is the initial step to assess for urinary retention in a postoperative client. This non-invasive technique helps determine the volume of urine in the bladder, guiding further interventions. Encouraging the client to drink fluids (Choice B) may be beneficial but is not the priority when assessing for urinary retention. Inserting a straight catheter (Choice C) should not be the initial action without first assessing for retention. Administering a diuretic (Choice D) should not be done without confirming the need through assessment.
Question 5 of 5
A client with diabetes mellitus is learning to self-administer insulin. Which action by the client indicates the need for further teaching?
Correct Answer: B
Rationale: Drawing up insulin after warming the vial to room temperature indicates a need for further teaching, as insulin should be at room temperature for administration. Choice A is correct as rotating injection sites helps prevent lipodystrophy. Choice C is correct as pinching the skin helps ensure proper subcutaneous injection. Choice D is correct as injecting insulin at a 90-degree angle is the recommended technique for subcutaneous injections.
