HESI PN Exit Exam 2023
1. A post-operative client is recovering from a total knee replacement and is prescribed patient-controlled analgesia (PCA). What is the primary advantage of PCA for managing post-operative pain?
- A. It allows for consistent pain control without overmedication.
- B. It eliminates the need for oral pain medication.
- C. It reduces the risk of opioid addiction.
- D. It requires less monitoring by nursing staff.
Correct answer: A
Rationale: The primary advantage of PCA for managing post-operative pain is that it allows the client to control the administration of pain medication, leading to consistent pain control without overmedication. Choice B is incorrect as PCA does not eliminate the need for oral pain medication; it supplements it. Choice C is incorrect because while PCA can help reduce opioid consumption, it does not directly reduce the risk of opioid addiction. Choice D is incorrect as PCA actually requires close monitoring by nursing staff to ensure proper use and prevent complications.
2. 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 PN reinforce about the action of the adjuvant pain modality?
- A. The discharge of electricity will distract the client's focus from the pain.
- B. An infusion of medication into 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 TENS unit works by providing a mild electrical stimulus to the skin, which helps to 'close the gate' on pain signals, reducing the perception of pain. Choice A is incorrect because distraction is not the primary mechanism of action for TENS. Choice B is incorrect as it describes a different method of pain management involving medication infusion into the spinal canal. Choice C is incorrect as it inaccurately describes the location of pain perception modulation by the TENS unit.
3. A client who is post-operative from a carotid endarterectomy is experiencing difficulty swallowing. What is the nurse's priority action?
- A. Administer a prescribed antiemetic.
- B. Assess the client’s airway and respiratory status.
- C. Elevate the head of the bed.
- D. Encourage the client to take small sips of water.
Correct answer: B
Rationale: The correct answer is to assess the client’s airway and respiratory status (Choice B). Difficulty swallowing after carotid endarterectomy could indicate swelling or nerve damage affecting swallowing, which may compromise the airway. Assessing the airway and respiratory status is crucial to ensure the client's ability to breathe. Administering an antiemetic (Choice A) is not the priority as the primary concern is airway patency. Elevating the head of the bed (Choice C) can help with swallowing difficulties but does not address the immediate risk to the airway. Encouraging the client to take small sips of water (Choice D) is contraindicated if there is a risk of compromised airway due to swallowing difficulties.
4. A client post-splenectomy is at risk for infection. What is the most important preventive measure the nurse should emphasize during discharge teaching?
- A. Take all prescribed antibiotics as directed.
- B. Avoid crowded places and people who are sick.
- C. Wash hands frequently and practice good hygiene.
- D. Keep the surgical site clean and dry.
Correct answer: C
Rationale: The correct answer is C: 'Wash hands frequently and practice good hygiene.' After a splenectomy, the client is at an increased risk of infection due to the role of the spleen in the immune system. Maintaining good hand hygiene, such as frequent handwashing, is crucial to prevent infections. While taking prescribed antibiotics as directed (Choice A) is important if prescribed, it is not the most crucial preventive measure in this scenario. Avoiding crowded places and sick people (Choice B) can help reduce the risk of exposure to pathogens but may not always be feasible. Keeping the surgical site clean and dry (Choice D) is important for wound care but is not the primary preventive measure to protect against infections in a post-splenectomy client.
5. Which laboratory value is most important to monitor for a patient receiving heparin therapy?
- A. Platelet count
- B. Prothrombin time (PT)
- C. Partial thromboplastin time (PTT)
- D. International normalized ratio (INR)
Correct answer: C
Rationale: The correct answer is C, Partial thromboplastin time (PTT). PTT is monitored to assess the therapeutic effect of heparin therapy. It helps ensure that the heparin levels are within the desired range to prevent either clotting or excessive bleeding. Platelet count (A) is important but does not directly assess heparin's therapeutic effect. Prothrombin time (PT) (B) and International normalized ratio (INR) (D) are used to monitor patients on warfarin, not heparin therapy.
