PN Exit Exam 2023 Quizlet

Correct Answer: A

Rationale: The practical nurse should record the findings and report the symptoms to the charge nurse. These behaviors may indicate a serious underlying condition such as depression or physical illness. By reporting to the charge nurse, the client can receive appropriate assessment and intervention promptly. Choice B is incorrect as family visits may not address the root cause of the symptoms. Choice C is incorrect as it oversimplifies the situation and may not be effective in addressing the underlying issue. Choice D is incorrect because withholding medications without proper assessment and guidance can be harmful to the client's health.

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.

Correct Answer: C

Rationale: The most effective way to communicate with a patient who has expressive aphasia is by using picture boards or communication cards. These tools allow patients to convey their needs and responses more effectively when they struggle to speak. Using picture boards or communication cards (Choice C) is preferred as it provides a visual aid to support communication. Asking yes or no questions (Choice A) may limit the patient's ability to express themselves fully. Encouraging the patient to write responses (Choice B) may not be suitable if the patient also has difficulty writing due to the aphasia. While speaking slowly and clearly (Choice D) is important, it may not be sufficient to overcome the communication challenges faced by patients with expressive aphasia.

Correct Answer: B

Rationale: A heart rate of 120 beats per minute is within the normal range for a 2-month-old infant. Therefore, it is safe to administer the digoxin and document the heart rate as part of routine care. Choice A is incorrect as withholding the medication is not necessary since the heart rate is normal. Choice C is incorrect as there is no need to delay the administration until the next scheduled dose when the heart rate is within the normal range. Choice D is incorrect as the primary nurse is not needed to administer the medication since the heart rate is normal and falls within the safe range for administration.

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.
