PN Exit Exam 2023 Quizlet

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: B

Rationale: The best action for the nurse to take in this situation is to wait for the client to excuse himself from the telephone conversation and then observe the client taking the medication. This approach ensures that the client takes the medication as prescribed, promoting compliance and safety. Choice A is not ideal as it involves unnecessary delegation and may lead to confusion. Choice C is incorrect because assuming refusal without direct communication can compromise patient care. Choice D is not recommended as leaving the medication with the client unsupervised may result in non-compliance or potential errors.

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.

Correct Answer: D

Rationale: Inspiratory and expiratory stridor are high-pitched, wheezing sounds caused by disrupted airflow due to airway obstruction. Severe laryngotracheitis, involving inflammation and swelling of the larynx and trachea, leads to airway obstruction and can produce both inspiratory and expiratory stridor. Exacerbation of goiter, an acute asthmatic attack, and aspiration of a piece of meat are not typically associated with both inspiratory and expiratory stridor. Therefore, choices A, B, and C are incorrect.

Correct Answer: C

Rationale: Sundowning, a phenomenon where dementia symptoms worsen in the evening, can be managed by ensuring the client is close to the nurses' station for frequent monitoring and quick intervention, if necessary. This reduces the risk of harm and helps manage agitation. Asking family members to remain with the client may not always be feasible and does not address the need for close monitoring. Administering benzodiazepines should not be the first-line intervention for sundowning as it can increase the risk of falls and other adverse effects. Postponing medication administration may disrupt the client's routine and potentially worsen symptoms.
