HESI LPN
HESI Fundamentals Exam
1. A healthcare professional is caring for a group of clients. Which of the following measures should the professional take to prevent the spread of infection?
- A. Place a client with TB in a room with negative pressure airflow
- B. Use a disposable gown for contact precautions
- C. Place a client with MRSA in a private room
- D. Use a mask for clients with influenza
Correct answer: A
Rationale: Tuberculosis is an airborne infection, and placing a client with TB in a room with negative pressure airflow helps prevent the spread of the infection by containing the pathogens. This measure is crucial as it prevents the dissemination of TB droplet nuclei to other areas. Choice B, using a disposable gown for contact precautions, is important for preventing the transmission of infections spread by direct or indirect contact. Choice C, placing a client with MRSA in a private room, is essential to prevent the spread of MRSA through contact with others. Choice D, using a mask for clients with influenza, helps prevent the spread of influenza through respiratory droplets. However, negative pressure airflow is specifically required for airborne infections like TB, making it the most appropriate choice in this scenario.
2. What instruction should the nurse provide for a UAP caring for a client with MRSA who has a prescription for contact precautions?
- A. Allow visitors with precautions in place
- B. Wear sterile gloves when handling the client's body fluid
- C. Have the client wear a mask whenever someone enters the room
- D. Don a gown and gloves when entering the room
Correct answer: D
Rationale: The correct instruction for a UAP caring for a client with MRSA under contact precautions is to don a gown and gloves when entering the room. Wearing a gown and gloves is necessary to prevent the transmission of MRSA. Choice A is incorrect because visitors may be allowed with proper precautions in place. Choice B is incorrect as it assumes the client has body fluid precautions, which is not specified. Choice C is incorrect as it does not address the UAP's protective measures but rather focuses on the client wearing a mask.
3. A nurse is caring for two clients who report following the same religion. Which of the following information should the nurse consider when planning care for these clients?
- A. Members of the same religion may have varying feelings about their religion.
- B. A shared religion background does not guarantee identical beliefs.
- C. The same religious beliefs can influence individuals differently.
- D. Discussing differences and commonalities in beliefs may not always be relevant.
Correct answer: C
Rationale: The correct answer is C. Religious beliefs can vary widely even among individuals of the same faith. It is essential for the nurse to recognize that the impact and interpretation of religious beliefs can differ from person to person. Choice A is incorrect as individuals within the same religion can have diverse feelings and interpretations. Choice B is incorrect because a shared religious background does not necessarily mean that individuals hold the same beliefs. Choice D is not the best course of action as discussing differences and commonalities in beliefs may not always be necessary or appropriate for providing care.
4. The healthcare provider prescribes potassium chloride 25 mEq in 500 ml D5W to infuse over 6 hours. The available 20 ml vial of potassium chloride is labeled '10 mEq/5 ml.' How many ml of potassium chloride should the nurse add to the IV fluid?
- A. 12.5
- B. 5
- C. 10
- D. 20
Correct answer: B
Rationale: To prepare 25 mEq of potassium chloride for the infusion, the nurse should add 5 ml of the 10 mEq/5 ml solution. This concentration provides the required amount of potassium chloride without exceeding the needed volume. Choice A would result in 12.5 mEq, which exceeds the prescribed amount. Choices C and D are incorrect as they do not align with the correct calculation based on the vial concentration.
5. The client with heart failure is prescribed furosemide (Lasix). What should the nurse include in the teaching plan?
- A. Increase potassium-rich foods in the diet
- B. Avoid foods high in sodium
- C. Monitor fluid intake and adjust as needed
- D. Take the medication in the morning
Correct answer: A
Rationale: The correct answer is to instruct the client to increase potassium-rich foods in the diet. Furosemide is a loop diuretic that can cause potassium loss as a side effect. By increasing potassium-rich foods, the client can help prevent hypokalemia, a potential complication of furosemide therapy. Choice B is incorrect because while limiting sodium intake is generally advisable for heart failure, it is not directly related to furosemide use. Choice C is incorrect because fluid intake should be monitored and adjusted based on the individual's condition, but setting a specific limit of 1 liter per day is not a standard recommendation. Choice D is incorrect because furosemide is usually taken in the morning to prevent disturbances in sleep due to increased urination during the night.
