HESI Medical Surgical Practice Exam Quizlet

Correct Answer: C

Rationale: During an ophthalmoscopic examination, the client should focus on a distant object behind the examiner to dilate the pupil, and the examiner should stand at a distance of 12-15 inches away and slightly to the side. This angle allows for better visualization of the retina. Holding the ophthalmoscope firmly against the examiner's face and shining the light into the client's pupil helps examine the retina effectively. Choice A is incorrect because the client should look at a distant object, not the examiner's nose. Choice B is incorrect as the ophthalmoscope should be directed towards the client's eye, not the examiner's eye. Choice D is incorrect because keeping the ophthalmoscope at least 3 inches away may not provide an optimal view of the retina.

Correct Answer: B

Rationale: Correct. Pheochromocytoma is a catecholamine-secreting non-cancerous tumor of the adrenal medulla. The classic triad of symptoms includes headache, diaphoresis (excessive sweating), and palpitations, which result from the overproduction of catecholamines like epinephrine and norepinephrine. Numbness, tingling, and cramps in the extremities (Option A) are not characteristic of pheochromocytoma. Cyanosis, fever, and classic signs of shock (Option C) are not typical symptoms of this condition. Nausea, vomiting, and muscular weakness (Option D) are not commonly associated with pheochromocytoma.

Correct Answer: B

Rationale: In this scenario, the client is 55 years old with a history of 'heart trouble,' which necessitates a recent ECG before surgery as per hospital policy. The nurse should prioritize patient safety and adhere to the protocol by arranging for an ECG to be performed immediately. Option A is not the best initial action as the focus should be on obtaining the necessary test first. Option C is not the immediate action required, and option D is premature without obtaining the necessary ECG first.

Correct Answer: B

Rationale: Parkinson's Disease, a common neurologic progressive disorder in older clients, is characterized by symptoms such as shuffling gait, masklike facial expression, and tremors of the head and hands. Choice A is incorrect as symptoms like loss of short-term memory, facial tics, and constant writhing movements are not typically associated with Parkinson's disease. Choice C is incorrect as extreme muscular weakness, easy fatigability, and ptosis are more indicative of other conditions like myasthenia gravis. Choice D is incorrect as numbness of the extremities, loss of balance, and visual disturbances are not classic symptoms of Parkinson's disease.

Correct Answer: D

Rationale: In this scenario, the client presents with significant weight loss, poor hygiene, and inadequate clothing, which are concerning signs of self-neglect. Before taking action, it is crucial for the nurse to collect more data to determine the root cause of these issues. Jumping to conclusions or immediately involving social services without a thorough assessment could potentially harm the client or strain relationships. Discussing the need for mental health counseling with the daughter or simply advising the client to take better care of herself may not address the underlying problem of self-neglect. Therefore, the most appropriate initial action is for the nurse to collect further data to make an informed decision before taking the next steps.
