PN Exit Exam 2023 Quizlet

HESI LPN

1. A client is admitted to the postoperative surgical unit with two test tubes after a left lobectomy. The nurse observed that the chambers are set at the prescribed suction of 20 cm water pressure, and tidying occurs with respirations and bubbling. What action should the nurse implement?

A. Clamp the chest tube to see if the bubbling activity stops
B. Notify the registered nurse of the observed bubbling
C. Maintain system integrity to promote lung reexpansion
D. Apply an occlusive dressing to the chest

Correct answer: C

Rationale: Maintaining system integrity is essential to promote lung reexpansion in postoperative patients with chest tubes. Clamping the chest tube abruptly can lead to tension pneumothorax, a life-threatening condition. The bubbling observed is a normal sign indicating that the system is functioning correctly, as it allows the drainage of air or fluid from the pleural space. Notifying the registered nurse may be necessary if there are significant concerns or changes observed, but the immediate action should be to ensure system integrity and lung reexpansion.

2. What is the most common cause of acute pancreatitis?

A. Gallstones
B. Alcohol abuse
C. Hypertriglyceridemia
D. Infection

Correct answer: A

Rationale: The correct answer is A: Gallstones. Gallstones are the most common cause of acute pancreatitis as they obstruct the pancreatic duct, leading to inflammation. While alcohol abuse (Choice B) can also cause pancreatitis, gallstones are more prevalent. Hypertriglyceridemia (Choice C) is a less common cause of acute pancreatitis compared to gallstones. Infection (Choice D) is not a primary cause of acute pancreatitis; gallstones are the leading etiology.

3. A client has a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management during the postoperative period following a lumbar laminectomy. Which information should the nurse reinforce about the action of this adjuvant pain modality?

A. The discharge of electricity will distract the client's focus from the pain
B. An infusion of medication in the spinal canal will block pain perception
C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain

Correct answer: D

Rationale: The correct answer is D. TENS works by delivering a mild electrical stimulus to the skin, which can help close the 'gates' in the nervous system to block pain signals from reaching the brain, thus reducing pain perception. Choice A is incorrect because TENS does not distract from pain but rather helps manage it. Choice B is incorrect as it describes a different pain management technique involving medication in the spinal canal. Choice C is incorrect because TENS acts peripherally on nerve conduction rather than dulling pain perception in the cerebral cortex.

4. A client post-thyroidectomy is being monitored for signs of hypocalcemia. Which of the following symptoms should the nurse be most concerned about?

A. Tingling in the hands and around the mouth.
B. Nausea and vomiting.
C. Constipation.
D. Bradycardia.

Correct answer: A

Rationale: The correct answer is A: Tingling in the hands and around the mouth. This symptom is a classic sign of hypocalcemia, which can occur after thyroidectomy if the parathyroid glands were inadvertently damaged during surgery. Nausea and vomiting (Choice B) are not specific to hypocalcemia. Constipation (Choice C) is not a typical symptom of hypocalcemia. Bradycardia (Choice D) is more commonly associated with hypothyroidism rather than hypocalcemia.

5. A nurse who receives a patient in the operative suite prior to the actual surgery is in charge of the patient’s care. Which of the following is NOT a task related to the nurse’s intraoperative care?

A. Go over the surgical procedure with the patient before he or she is anesthetized
B. Strictly adhere to asepsis during all intraoperative procedures
C. Provide emotional support to the patient and their family
D. Monitor the patient’s physical status

Correct answer: A

Rationale: The correct answer is A. Going over the surgical procedure with the patient is typically done preoperatively, not intraoperatively. Intraoperative tasks of a nurse involve strictly adhering to asepsis during procedures, monitoring the patient's physical status, and providing emotional support to the patient and their family during the surgery. Choices B, C, and D are all tasks that are directly related to the nurse's responsibilities during the intraoperative phase of care.
