HESI Fundamentals Study Guide
1. A nurse is caring for a group of clients on a medical-surgical unit. In which of the following situations does the nurse demonstrate the ethical principle of veracity?
- A. A client unaware of her recent cancer diagnosis asks the nurse if she has cancer, and the nurse responds affirmatively.
- B. The nurse avoids discussing the client's diagnosis to prevent emotional distress.
- C. The nurse provides a vague answer about the client's condition.
- D. The nurse promises to provide information only if it is requested by the client.
Correct answer: A
Rationale: Veracity involves telling the truth, a fundamental ethical principle in healthcare. In this scenario, the nurse demonstrates veracity by responding honestly when the client directly asks about her cancer diagnosis. Choice B is incorrect as avoiding discussing the diagnosis to prevent emotional distress does not align with veracity and transparency. Choice C is incorrect as providing a vague answer does not uphold the principle of truthfulness. Choice D is incorrect because promising to provide information only upon client request does not address the immediate question about the cancer diagnosis and lacks transparency.
2. 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.
3. The nurse is preparing to assist a newly admitted client with personal hygiene measures. The nurse wants to assess the client's gag reflex. Which action should the nurse include?
- A. Offer small sips of water through a straw
- B. Place tongue blade on back half of tongue
- C. Use a penlight to observe back of the oral cavity
- D. Auscultate breath sounds after the client swallows
Correct answer: B
Rationale: The correct action for the nurse to include when assessing the client's gag reflex is to place a tongue blade on the back half of the tongue. This method effectively tests the gag reflex without causing discomfort. Choice A is incorrect because offering small sips of water through a straw does not assess the gag reflex. Choice C is incorrect as using a penlight to observe the back of the oral cavity does not directly assess the gag reflex. Choice D is incorrect since auscultating breath sounds after the client swallows does not evaluate the gag reflex.
4. When admitting a 5-month-old who has vomited 9 times in the past 6 hours, what should the healthcare provider observe for signs of which overall imbalance?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Increased serum hemoglobin levels
- D. Decreased serum potassium levels
Correct answer: B
Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.
5. 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.
