HESI LPN
Fundamentals HESI Questions
Question 1 of 5
The healthcare provider prescribes furosemide (Lasix) 15 mg IV stat. On hand is Lasix 20 mg/2 ml. How many milliliters should the LPN/LVN administer?
Correct Answer: B
Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.
Question 2 of 5
To ensure the safety of a client receiving a continuous intravenous normal saline infusion, how often should the LPN change the administration set?
Correct Answer: D
Rationale: The correct answer is to change the administration set every 72 to 96 hours. This practice helps reduce the risk of infection by preventing the build-up of bacteria in the tubing. Changing the set too frequently (choices A, B, and C) may increase the chances of contamination and infection without providing additional benefits. Therefore, the LPN should follow the guideline of changing the administration set every 72 to 96 hours to maintain the client's safety during the continuous intravenous normal saline infusion.
Question 3 of 5
Why should a client with an ileal conduit be instructed to empty the collection device frequently?
Correct Answer: C
Rationale: A full urine collection bag can cause the device to pull away from the skin, leading to potential leakage and skin irritation. Choice A is incorrect because a full urine collection bag does not force urine to back up into the kidneys. Choice B is incorrect as a full collection bag does not suppress the production of urine. Choice D is incorrect as a full collection bag is unlikely to tear the ileal conduit.
Question 4 of 5
During a blood transfusion, which observation indicates that the client is experiencing a transfusion reaction?
Correct Answer: D
Rationale: Complaints of back pain and shortness of breath are classic signs of a transfusion reaction, specifically indicating a hemolytic reaction. This reaction can lead to the release of hemoglobin into the bloodstream, causing back pain and shortness of breath due to clot formation in the blood vessels, leading to decreased oxygen delivery. Warmth, flushing, rash, chills, and fever are more commonly associated with allergic reactions or febrile non-hemolytic reactions during transfusions. Therefore, options A, B, and C are incorrect in this context.
Question 5 of 5
A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the LPN/LVN monitor closely while the client is taking this medication?
Correct Answer: B
Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.
