HESI Fundamentals Practice Test Questions
Question 1 of 5
Why is it most important to start intravenous infusions in the upper extremities rather than the lower extremities of adults?
Correct Answer: B
Rationale: The most critical reason for initiating intravenous infusions in the upper extremities of adults is to reduce the risk of thrombosis (B). Venous return is typically better in the upper extremities, decreasing the likelihood of thrombus formation, which could be life-threatening if dislodged. Although superficial veins are easily found in the feet and ankles (A), this is not the primary reason for choosing the upper extremities. Handling a leg or foot with an IV (C) is not significantly more challenging than handling an arm or hand. The depth of veins in the feet and ankles (D) does not primarily determine the site for IV placement.
Question 2 of 5
A hospitalized male client is receiving nasogastric tube feedings via a small-bore tube and a continuous pump infusion. He reports that he had a bad bout of severe coughing a few minutes ago but feels fine now. What action is best for the nurse to take?
Correct Answer: C
Rationale: Coughing, vomiting, and suctioning can precipitate displacement of the tip of the small-bore feeding tube upward into the esophagus, placing the client at increased risk for aspiration. Checking the sample of fluid withdrawn from the tube (after clearing the tube with 30 ml of air) for acidic (stomach) or alkaline (intestine) values is a more sensitive method for these tubes. The nurse should assess tube placement in this way before taking any other action to ensure the tube is still in the correct position and prevent potential complications. Choice A is incorrect because further assessment is needed due to the risk of tube displacement. Choice B is incorrect as stopping the feeding and involving the family is premature without confirming tube placement. Choice D is incorrect as injecting air and auscultating for gurgling is not the recommended method to confirm tube placement.
Question 3 of 5
After hemodialysis, a client with a history of chronic renal failure has just returned to the unit. What is the most important assessment for the nurse to make?
Correct Answer: D
Rationale: The most crucial assessment for the nurse to make after hemodialysis in a client with chronic renal failure is to check the client's fistula for bruit and thrill (D). This assessment is essential to ensure the patency of the fistula and adequate blood flow. Auscultating lung sounds (A), assessing blood pressure (B), and monitoring weight (C) are important assessments but are secondary to evaluating the fistula. Checking the fistula is vital as it directly impacts the effectiveness of the client's dialysis treatment and the patency of the vascular access, ensuring successful dialysis sessions.
Question 4 of 5
What is the most important action for the nurse to take when caring for a client with a spinal cord injury experiencing autonomic dysreflexia?
Correct Answer: A
Rationale: In a client with autonomic dysreflexia, the most critical action is to elevate the head of the bed to 45 degrees (A). This positioning helps reduce blood pressure, which is essential in managing autonomic dysreflexia. Monitoring the client's respiratory rate (B) is important for overall assessment but not the priority in this situation. Administering an antihypertensive medication (C) without addressing the positioning issue first can lead to further complications. Assessing the client's blood glucose level (D) is not directly related to autonomic dysreflexia and is not the initial priority in this scenario.
Question 5 of 5
A client who has been on bed rest for several days is at risk for developing deep vein thrombosis (DVT). Which intervention should the nurse include in the client's plan of care?
Correct Answer: B
Rationale: Applying antiembolism stockings as prescribed (B) is an effective intervention to prevent deep vein thrombosis (DVT) in a client on bed rest. While encouraging ambulation (A), elevating the legs (C), and performing passive range-of-motion exercises (D) are also beneficial, compression stockings are particularly effective in reducing the risk of DVT by promoting venous return and reducing stasis in the lower extremities.
