HESI LPN
Practice HESI Fundamentals Exam Questions
Question 1 of 5
A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg · 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.
Question 2 of 5
A nurse prepares an injection of morphine to administer to a client who reports pain but asks a second nurse to give the injection because another assigned client needs to use a bedpan. Which of the following actions should the second nurse take?
Correct Answer: C
Rationale: The second nurse should prepare a new syringe and administer the medication to ensure proper and timely pain management. Administering another nurse's medication without preparation could lead to errors. Choice A is not the priority as the medication administration should take precedence. Choice B is not recommended as the second nurse should not administer medication prepared by another nurse. Choice D is inappropriate as patient needs should not be compromised for medication administration to another client.
Question 3 of 5
A client is evaluated by a nurse regarding the use of a sequential compression device. Which of the following client statements indicates understanding of the device's purpose?
Correct Answer: B
Rationale: The correct answer is B because sequential compression devices are utilized to enhance circulation and prevent clot formation in the legs. Option A is incorrect because these devices are not primarily meant to prevent skin sores. Option C is incorrect because the devices do not directly address muscle weakness. Option D is incorrect as the main purpose of sequential compression devices is not related to joint health.
Question 4 of 5
A client with a terminal illness is expected to pass away within 24 hours. The family asks the nurse about what to expect at this time. Which of the following findings should the nurse include?
Correct Answer: D
Rationale: As death approaches, decreased muscle tone and other signs like decreased blood pressure, irregular breathing patterns, cold extremities, and decreased urine output are common. Warm extremities (choice B) would not be expected as circulation may be compromised. Increased urine output (choice C) is unlikely as organ function declines. A regular breathing pattern (choice A) is also unlikely as irregular breathing patterns are common near death.
Question 5 of 5
During a neurologic examination, which assessment should a nurse perform to test a client's balance?
Correct Answer: A
Rationale: The Romberg test is used to assess a client's balance by evaluating their ability to maintain a steady posture with eyes closed. The heel-to-toe walk is another assessment that tests balance by assessing gait and coordination. The Snellen test is used to assess visual acuity and is unrelated to balance. Testing spinal accessory function involves assessing the movement of the head and shoulders and is not directly related to balance assessment.
