HESI LPN
HESI Fundamental Practice Exam
1. A nurse at an assisted living facility is preparing an in-service for residents about electrical safety. Which of the following instructions should the nurse include?
- A. Avoid taping electrical cords to the floor.
- B. Clean electrical equipment before disconnection.
- C. Cover exposed wires with tape before use.
- D. Disconnect electrical equipment by grasping the plug.
Correct answer: A
Rationale: The correct instruction for electrical safety is to avoid taping electrical cords to the floor. Taping cords can create tripping hazards, leading to falls and potential injuries. Choice B, cleaning electrical equipment before disconnection, is not directly related to electrical safety but rather to equipment maintenance. Choice C, covering exposed wires with tape before use, is incorrect as exposed wires should be properly insulated and repaired by a qualified professional. Choice D, disconnecting electrical equipment by grasping the plug, is unsafe and can lead to electrical shocks. It is always recommended to unplug devices by holding the plug itself, not by pulling the cord.
2. A newly licensed nurse is preparing to administer medications to a client. The nurse notes that the provider has prescribed a medication that is unfamiliar. Which of the following actions should the nurse take?
- A. Consult the medication reference book available on the unit.
- B. Administer the medication as ordered.
- C. Ask a colleague for information about the medication.
- D. Contact the provider to clarify the medication.
Correct answer: A
Rationale: When encountering an unfamiliar medication, the safest action for a nurse is to consult the medication reference book available on the unit. This resource provides accurate and detailed information about medications, including indications, dosages, side effects, and nursing considerations. Administering a medication without understanding it (choice B) can lead to medication errors and harm to the client. Asking a colleague for information (choice C) may not always provide accurate or up-to-date information. Contacting the provider (choice D) should be reserved for situations where immediate clarification is needed, but consulting the reference book is the initial step to gain knowledge and ensure safe medication administration.
3. The nurse is evaluating client learning about a low-sodium diet. Selection of which meal would indicate to the LPN that this client understands the dietary restrictions?
- A. Tossed salad with low-sodium dressing, bacon, and tomato sandwich.
- B. New England clam chowder, unsalted crackers, fresh fruit salad.
- C. Skim milk, turkey salad, roll, and vanilla ice cream.
- D. Macaroni and cheese, diet Coke, and a slice of cherry pie.
Correct answer: C
Rationale: The correct answer is C: Skim milk, turkey salad, roll, and vanilla ice cream. These items are low in sodium, making it a suitable meal for someone on a low-sodium diet. Skim milk, turkey salad, and vanilla ice cream are naturally low in sodium, while the roll can be selected as a low-sodium option. Choices A, B, and D contain items that are typically high in sodium, such as bacon, clam chowder, crackers, and cheese, making them unsuitable for a low-sodium diet.
4. A charge nurse is observing a newly licensed nurse prepare a sterile field. Which of the following actions should the charge nurse identify as contaminating the sterile field?
- A. The nurse opens the sterile field on a wet surface.
- B. The nurse turns away from the sterile field.
- C. The nurse uses a non-sterile glove to touch the sterile field.
- D. The nurse touches the edge of the sterile drape with her hand.
Correct answer: A
Rationale: The correct answer is A. Opening the sterile field on a wet surface contaminates it, rendering it unsafe for use. Moisture can carry microorganisms that can compromise the sterility of the field. Choice B is incorrect because turning away from the sterile field alone does not necessarily contaminate it unless the nurse touches non-sterile items. Choice C is incorrect because using a non-sterile glove to touch the sterile field directly introduces contaminants. Choice D is incorrect as touching the edge of the sterile drape with a hand may not necessarily contaminate the entire field, unlike opening it on a wet surface.
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?
- A. 1 ml.
- B. 1.5 ml.
- C. 1.75 ml.
- D. 2 ml.
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.
