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. 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.
3. During the initial physical assessment of a newly admitted client with a pressure ulcer, an LPN observes that the client's skin is dry and scaly. The nurse applies emollients and reinforces the dressing on the pressure ulcer. Legally, were the nurse's actions adequate?
- A. The nurse should have also initiated a plan to increase activity.
- B. The nurse provided supportive nursing care for the well-being of the client.
- C. Debridement of the pressure ulcer should have been performed before applying the dressing.
- D. Treatment should not have been initiated until the healthcare provider's prescriptions were received.
Correct answer: B
Rationale: The correct answer is B. Providing supportive nursing care, such as applying emollients and reinforcing the dressing on the pressure ulcer, meets the immediate needs of the client and is in line with legal and professional standards. Option A is incorrect because increasing activity may not be directly related to the immediate skin care needs of the client. Option C is incorrect as debridement might not be immediately necessary based on the initial assessment. Option D is incorrect as nurses are often authorized to initiate treatments within their scope of practice without waiting for healthcare provider prescriptions, especially for routine care like skin moisturization and dressing reinforcement.
4. A client has a new prescription for a home oxygen concentrator. Which of the following instructions should the nurse provide to the client and their family?
- A. Check the cord routinely for frays or tearing
- B. Use oxygen around open flames
- C. Store oxygen concentrator in a closet
- D. Wear synthetic clothing to prevent static electricity
Correct answer: A
Rationale: The correct answer is to instruct the client and their family to check the cord routinely for frays or tearing. This is crucial to ensure the safety and proper function of the oxygen concentrator. Choice B is incorrect because oxygen should never be used around open flames due to the risk of fire. Choice C is also incorrect as oxygen cylinders or concentrators should not be stored in a closet due to ventilation and safety concerns. Choice D is incorrect because synthetic clothing can generate static electricity, which could pose a risk around oxygen equipment.
5. When planning care for a newly admitted elderly client who is severely dehydrated, which task is appropriate to assign to an unlicensed assistive personnel (UAP)?
- A. Converse with the client to determine if the mucous membranes are impaired
- B. Report hourly outputs of less than 30 ml/hr
- C. Monitor client's ability to move in the bed
- D. Check skin turgor every 4 hours
Correct answer: B
Rationale: The correct answer is B. Assigning the UAP to report hourly outputs of less than 30 ml/hr is appropriate as it falls within their scope of practice and does not involve making clinical assessments or decisions. Choices A, C, and D involve tasks that require a higher level of clinical judgment and training. Choice A requires assessing mucous membranes, which is beyond the UAP's scope. Choice C involves assessing movement ability, which requires more specialized training. Choice D involves assessing skin turgor, which also requires a higher level of clinical judgment.
