PATHO 370 TEST 7 - Questions, Answers and Response Feedback

• Question 1 0.125 out of 0.125 points Risk factors for hemorrhagic stroke include Selected Answer: d. acute hypertension. Correct Answer: d. acute hypertension. Response Feedback: Intracerebral hemorrhage is a hemorrhage within the brain parenchyma and usually occurs in the context of severe and often longstanding hypertension. Risk factors for stroke are similar to those for other atherosclerotic vascular disease. Cardiac disease complicated by atrial fibrillation is an important risk factor for embolic stroke. Sedentary lifestyle is not a risk factor for hemorrhagic stroke. • Question 2 0 out of 0.125 points A severe complication of elevated intracranial pressure is Selected Answer: b. hydrocephalus. Correct Answer: d. brain herniation. Response Feedback: A dreaded complication of elevated ICP is brain compression and herniation. Compression of midbrain and brainstem structures is associated with rapid neurologic demise unless corrected quickly. An extreme increase in ICP precipitates a reaction by the sympathetic nervous system as it attempts to maintain perfusion. Cushing reflex is the brain’s effort to reestablish cerebral perfusion. A burr hole is an opening in the skull which is used to monitor ICP. A cause of increased ICP is an excessive accumulation of CSF (hydrocephalus). • Question 3 0.125 out of 0.125 points Anticholinesterase inhibitors may be used to manage Selected Answer: d. myasthenia gravis. Correct Answer: d. myasthenia gravis. Response Feedback: Anticholinesterase inhibitors may be used to manage myasthenia gravis. Anticholinesterase agents are not used to manage muscular dystrophy, fibromyalgia, or rheumatoid arthritis. • Question 4 0.125 out of 0.125 points Parkinson disease is associated with Selected Answer: c. a deficiency of dopamine in the substantia nigra. Correct Answer: c. a deficiency of dopamine in the substantia nigra. Response Feedback: Parkinson disease results from degeneration of the pigmented dopaminergic neurons found in the substantia nigra. Demyelination of CNS neurons is not associated with Parkinson disease. Parkinson disease is not associated with a pyramidal nerve tract lesion. Decreased acetylcholine synthesis has been found in some studies related to Alzheimer disease. • Question 5 0.125 out of 0.125 points The most common site affected in Paget’s disease is the Selected Answer: d. lower spine. Correct Answer: d. lower spine. Response Feedback: The lower spine is the most common site affected in Paget’s disease. The skull and pelvis are affected, but are not the most common sites. Joints are not affected in Paget’s disease.
