Nursing 611 Exam 2 Questions with
Correct Answers 2026
Parasympathetic Nervous System - CORRECT ANSWER -conserves energy and the body's
resources.
Sympathetic Nervous System - CORRECT ANSWER -responds to stress by preparing the body to
defend itself
Catecholamines released - epinephrine
mobilizing energy stores, and decreases the release of insulin;
redistributes blood flow - increases to muscles (flight) and lungs, decreases to GI and
integumentary
Focal - Direct Impact - CORRECT ANSWER -are specific, brain lesions that occur in a precise
location Epidural hemorrhage; subdural hemorrhage.
Diffuse injuries - CORRECT ANSWER -♥Diffuse Axonal Injury (DAI)
•Follows acceleration-deceleration injuries where there is a rotational element
•Characterized by mild to severe axonal injury
•Results in scattered, diffuse loss of function
•A continuum of injury from DAI ranges from concussion to persistent vegetative state
Swelling, commonly seen after Traumatic Brain Injury (TBI), can lead to dangerous increases in
intracranial pressure. - CORRECT ANSWER -increased pressure can cause collateral dysfunction:
Diabetes Insipidus (ADH not secreted thus polyuria)
Autonomic hyperreflexia (dysreflexia) - CORRECT ANSWER -Affected at the T5-T6 level or above.
, Characterized by
paroxysmal hypertension (up to 300 mm Hg systolic),
a pounding headache,
blurred vision
sweating above the level of the lesion with flushing of the skin
The spinal cord injury results in disturbed thermal control because the hypothalamus is unable
to regulate body heat as a result of a damaged sympathetic nervous system.
bradycardia (30 to 40 beats/minute).
Stimulation of the carotid sinus to the vagus nerve to the sinoatrial node.
Delirium vs Dementia - CORRECT ANSWER -1. Delirium- Acute, dramatic onset, common causes=
illness, toxin, withdrawal, usually reversible. Poor attention and fluctating arousal level. Intense
Autonomic Nerv System Hyperactivity
2. Dementia: Chronic, insidious onset, usually not reversible, attention usually unaffected and
normal arousal level.
Alzheimer Disease - CORRECT ANSWER -Alzheimer Disease is the leading cause of dementia and
one of the most common causes of severe cognitive dysfunction in older adults. The greatest
risk factors are age and family history.
The exact cause of AD is unknown and there is no clear understanding of this complex disease
process. The specific diagnosis of AD is made by postmortem examination.
Stroke - CORRECT ANSWER -Strokes are classified according to pathophysiology: ischemic
(thrombotic or embolic) is the most common, global hypoperfusion (as in shock), or
intracerebral hemorrhage. Middle cerebral artery (MCA) (most common area); either stem or
branches of MCA.
