HESI LPN
HESI CAT Exam
1. A client is admitted to a medical unit with the diagnosis of gastritis and chronic heavy alcohol abuse. What should the nurse administer to prevent the development of Wernicke's syndrome?
- A. Lorazepam (Ativan)
- B. Famotidine (Pepcid)
- C. Thiamine (Vitamin B1)
- D. Atenolol (Tenormin)
Correct answer: C
Rationale: Thiamine supplementation is critical in preventing Wernicke's syndrome, especially in clients with chronic alcohol use. Wernicke's syndrome is a neurological disorder caused by thiamine deficiency. Lorazepam is a benzodiazepine used for anxiety and not for preventing Wernicke's syndrome. Famotidine is an H2 blocker used to reduce stomach acid production but does not prevent Wernicke's syndrome. Atenolol is a beta-blocker used for hypertension and angina, not for preventing Wernicke's syndrome.
2. The nurse is caring for a client postoperatively following a hip replacement. Which intervention is most important to prevent dislocation of the prosthesis?
- A. Keep the client in a low Fowler's position
- B. Maintain hip abduction with pillows
- C. Encourage early ambulation
- D. Place the client in a prone position
Correct answer: B
Rationale: Maintaining hip abduction with pillows is crucial in preventing dislocation of the hip prosthesis postoperatively. This position helps keep the hip joint stable and reduces the risk of the prosthesis becoming displaced. Choices A, C, and D are not as effective in preventing dislocation. Keeping the client in a low Fowler's position does not provide the necessary hip support. While early ambulation is important for circulation and preventing complications, maintaining hip abduction is more specific to preventing prosthesis dislocation. Placing the client in a prone position can increase the risk of hip prosthesis dislocation due to the extreme positioning.
3. A healthcare professional is reviewing measures to prevent back injuries with assistive personnel (AP). Which of the following instructions should the healthcare professional include?
- A. When lifting an object, spread your feet apart to provide a wide base of support.
- B. Always lift objects with your back straight and not your legs.
- C. Avoid using any assistive devices.
- D. Bend at the waist to reach objects.
Correct answer: A
Rationale: The correct instruction to prevent back injuries while lifting is to spread your feet apart to provide a wide base of support. This helps in maintaining stability and reduces the risk of back injury. Choice B is incorrect as lifting objects with your back straight and using your legs is the recommended technique. Choice C is incorrect because assistive devices can actually help prevent back injuries by providing support. Choice D is incorrect as bending at the waist to reach objects can strain the back muscles and increase the risk of injury.
4. While providing care to a group of patients, which patient should the nurse prioritize seeing first?
- A. A patient with a hip replacement on prolonged bed rest reporting chest pain and dyspnea
- B. A bedridden patient with a reddened area on the buttocks who needs to be turned
- C. A patient on bed rest with renal calculi who needs to go to the bathroom
- D. A patient post-knee surgery who needs range of motion exercises
Correct answer: A
Rationale: The nurse should prioritize seeing the patient with a hip replacement on prolonged bed rest reporting chest pain and dyspnea first. This patient is at higher risk for deep vein thrombosis due to prolonged bed rest, which can lead to a life-threatening embolus. Chest pain and dyspnea could also indicate a potential pulmonary embolism, which requires immediate assessment and intervention. The other patients, while requiring care, do not present with symptoms that suggest an immediate life-threatening situation, making them lower priority at this time. Therefore, option A is the correct choice as it addresses a potentially critical condition that requires immediate attention.
5. The nurse is caring for a client who has just returned from surgery with an indwelling urinary catheter in place. What is the most important assessment for the nurse to make?
- A. Check for catheter patency
- B. Assess the color of the urine
- C. Measure the urine output
- D. Ensure the catheter tubing is secure
Correct answer: C
Rationale: The most important assessment for the nurse to make in this situation is to measure the urine output. This assessment is crucial in monitoring kidney function and fluid balance after surgery. While checking for catheter patency is important, it is not as critical as measuring urine output. Assessing the color of the urine can provide some information about kidney function, but measuring output gives a more accurate assessment. Ensuring the catheter tubing is secure is essential to prevent dislodgement but is not the most critical assessment to make at this time.
