PN Exit Exam 2023 Quizlet

Correct Answer: B

Rationale: Providing a diversionary activity is the most appropriate nursing intervention to promote comfort for a client with pericarditis. This intervention helps to distract the patient and reduce discomfort by focusing their attention elsewhere. Auscultating heart sounds, while important for monitoring the condition, does not directly address the client's comfort. Encouraging deep breathing can be beneficial for some conditions but may not be specifically aimed at promoting comfort in pericarditis. Maintaining a patent intravenous access is essential for treatment access and management of the condition, but it does not directly promote comfort for the client.

Correct Answer: B

Rationale: The correct answer is B: Ensuring the tracheostomy ties are secure. This is the nurse's first priority because it is critical to prevent accidental decannulation, which could compromise the patient's airway. Providing humidified oxygen, suctioning the tracheostomy tube, and monitoring for signs of infection are important aspects of care but ensuring the tracheostomy ties' security takes precedence to maintain the patient's airway.

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.

Correct Answer: A

Rationale: The correct answer is A: 'To prevent deep vein thrombosis (DVT).' Sequential compression devices (SCDs) are primarily used to prevent deep vein thrombosis (DVT) by promoting blood flow in the legs and reducing venous stasis, which is a common risk for post-operative clients who are on bed rest. While SCDs do improve circulation in the legs indirectly, their primary purpose is DVT prevention. Preventing pressure ulcers is typically achieved through repositioning and support surfaces, not with SCDs, making choice C incorrect. SCDs are not used to alleviate post-operative pain, so choice D is also incorrect.

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.
