HESI LPN
Fundamentals of Nursing HESI Questions
Question 1 of 5
The nurse plans to assist a male client out of bed for the first time since his surgery yesterday. His wife objects and tells the nurse to get out of the room because her husband is too ill to get out of bed.
Correct Answer: D
Rationale: Checking the client's blood pressure and pulse deficit is essential before mobilizing a client out of bed, especially after surgery. This assessment helps ensure the client's stability and readiness for mobilization. Administering oxygen or pivoting the client without prior assessment could pose risks if the client is not medically stable. Helping the client lie back down without proper evaluation may delay necessary interventions if the client is indeed ready for mobilization.
Question 2 of 5
Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?
Correct Answer: A
Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.
Question 3 of 5
A client with acute hemorrhagic anemia is to receive four units of packed RBCs (red blood cells) as rapidly as possible. Which intervention is most important for the LPN/LVN to implement?
Correct Answer: D
Rationale: Ensuring the accuracy of the blood type match is crucial to prevent transfusion reactions. The LPN/LVN must prioritize this step to avoid adverse outcomes. Obtaining the pre-transfusion hemoglobin level (Option A) is important but not as critical as ensuring blood type compatibility. Priming the tubing and setting up the blood pump (Option B) and monitoring vital signs every 15 minutes (Option C) are essential steps in the transfusion process, but the primary concern should be preventing transfusion reactions by verifying blood type compatibility.
Question 4 of 5
The nurse is caring for a client who is receiving 24-hour total parenteral nutrition (TPN) via a central line at 54 ml/hr. When initially assessing the client, the nurse notes that the TPN solution has run out and the next TPN solution is not available. What immediate action should the nurse take?
Correct Answer: C
Rationale: Infusing 10% dextrose and water at 54 ml/hr is the correct action to prevent hypoglycemia until the next TPN solution becomes available. This solution will help maintain the client's glucose levels. Infusing normal saline at a keep-vein-open rate (Choice A) is not appropriate for maintaining glucose levels and would not address the nutritional needs provided by TPN. Discontinuing the IV and flushing the port with heparin (Choice B) is unnecessary and not indicated in this situation as the client still needs fluid and nutrition. Obtaining a stat blood glucose level and notifying the healthcare provider (Choice D) can be done later but is not the immediate action required when the TPN solution has run out.
Question 5 of 5
A health care provider has prescribed isoniazid (Laniazid) for a client. Which instruction should the LPN give the client about this medication?
Correct Answer: D
Rationale: The correct answer is D. When taking isoniazid, alcohol consumption should be avoided as it can increase the risk of liver damage, potentially leading to drug-induced hepatitis. Choices A, B, and C are incorrect. Prolonged use of isoniazid does not typically cause dark concentrated urine; it is not necessary to take the medication on an empty stomach for optimal absorption; and it is not recommended to take isoniazid with aluminum hydroxide to minimize GI upset.
