HESI LPN
HESI Fundamentals Exam Test Bank Questions
Question 1 of 5
A client is to receive cimetidine (Tagamet) 300 mg q6h IVP. The preparation arrives from the pharmacy diluted in 50 ml of 0.9% NaCl. The LPN plans to administer the IVPB dose over 20 minutes. For how many ml/hr should the infusion pump be set to deliver the secondary infusion?
Correct Answer: A
Rationale: Setting the infusion pump to 150 ml/hr ensures the correct administration rate of the IVPB dose over 20 minutes. To calculate the infusion rate, consider that the total volume to be infused is 50 ml over 20 minutes. To convert this to ml/hr, the calculation is (50 ml / 20 minutes) x 60 minutes/hr = 150 ml/hr. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate needed to deliver the secondary infusion over the specified time.
Question 2 of 5
A client who is 5'5" tall and weighs 200 pounds is scheduled for surgery the next day. What question is most important for the LPN to include during the preoperative assessment?
Correct Answer: B
Rationale: During the preoperative assessment, it is crucial for the LPN to inquire about the client's intake of vitamin and mineral supplements. This is important because certain supplements can have effects on coagulation, wound healing, and overall surgical outcomes. Asking about daily calorie consumption (Choice A) is not as pertinent as inquiring about vitamin and mineral supplements in this context. Questioning the client about feeling overweight (Choice C) may not directly impact the surgical outcome compared to the effects of supplements. Inquiring about the post-surgery diet (Choice D) is relevant but not as critical as understanding the client's supplement intake.
Question 3 of 5
The healthcare provider prescribes 1,000 ml of Ringer's Lactate with 30 Units of Pitocin to run over 4 hours for a client who has just delivered a 10-pound infant by cesarean section. The tubing has been changed to a 20 gtt/ml administration set. The LPN/LVN plans to set the flow rate at how many gtt/min?
Correct Answer: B
Rationale: To calculate the flow rate in drops per minute (gtt/min), the formula is Total volume (mL) · Time (min) · Drop factor (gtt/mL). In this case, 1000 mL · 240 min · 20 gtt/mL = 83 gtt/min. Therefore, setting the flow rate to 83 gtt/min ensures the correct administration of the IV fluids and medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the provided information.
Question 4 of 5
During the initial physical assessment of a newly admitted client with a pressure ulcer, an LPN observes that the client's skin is dry and scaly. The nurse applies emollients and reinforces the dressing on the pressure ulcer. Legally, were the nurse's actions adequate?
Correct Answer: B
Rationale: The correct answer is B. Providing supportive nursing care, such as applying emollients and reinforcing the dressing on the pressure ulcer, meets the immediate needs of the client and is in line with legal and professional standards. Option A is incorrect because increasing activity may not be directly related to the immediate skin care needs of the client. Option C is incorrect as debridement might not be immediately necessary based on the initial assessment. Option D is incorrect as nurses are often authorized to initiate treatments within their scope of practice without waiting for healthcare provider prescriptions, especially for routine care like skin moisturization and dressing reinforcement.
Question 5 of 5
Following surgery on the neck, the client asks the LPN why the head of the bed is up so high. The LPN should tell the client that the high-Fowler position is preferred for what reason?
Correct Answer: D
Rationale: The high-Fowler position is preferred after neck surgery to reduce edema at the operative site. Elevating the head of the bed promotes venous return and drainage, aiding in decreasing swelling and fluid accumulation, which helps reduce edema at the operative site. Choice A is incorrect as the main purpose is not solely about reducing strain on the incision. Choice B is incorrect because while drainage may occur, it is not the primary reason for maintaining the high-Fowler position. Choice C is incorrect as providing stimulation is not the primary rationale for positioning the client in high-Fowler.
