NUR 611 EXAM WITH COMPLETE SOLUTIONS
What makes up the autonomic nervous system? - CORRECT ANSWER✔✔Sympathetic and
parasympathetic nervous system
What is the parasympathetic nervous system responsible for? - CORRECT ANSWER✔✔Conserving
energy and the body's resources
What is the sympathetic nervous system responsible for? - CORRECT ANSWER✔✔Catecholamine
release - Epinephrine
Mobilizing energy stores and decreasing release of insulin
Redistributing blood low - Increasing to muscles and lungs (flight) and decreasing to GI/Integumentary
What are the classifications of primary brain injury? - CORRECT ANSWER✔✔Focal or diffuse
What are focal brain injuries? - CORRECT ANSWER✔✔Specific, grossly observable lesions that occur
in a precise location
What are examples of focal brain injuries? - CORRECT ANSWER✔✔Epidural hemorrhage and subdural
hemorrhage
What are examples of diffuse brain injuries? - CORRECT ANSWER✔✔Hypoxia, meningitis,
encephalitis, and damage to blood vessels

, What can happen with increased intracranial pressures? - CORRECT ANSWER✔✔Collateral
dysfunction such as Diabetes Insipidus
What are characteristics of autonomic hyperreflexia? - CORRECT ANSWER✔✔Paroxysmal
hypertension, pounding headache, blurred vision, sweating above level of lesion with flushing of skin,
nasal congestion, nausea, piloerection causes by pilomotor spasm, and bradycardia.
What is the sequence of events leading to hyperreflexia induced bradycardia? - CORRECT
ANSWER✔✔Stimulation of the carotid sinus nerve to the sinoatrial nose
The intact autonomic nervous system reflexively responds with arteriolar spasm that increases blood
pressure
Baroreceptors in the cerebral vessels, carotid sinus, and aorta sense the hypertension and stimulation
the parasympathetic nervous system
The heart rate decreases, but the visceral and peripheral vessels do not dilate because efferent impulses
cannot pass through the cord
What are the onset of delirium and dementia? - CORRECT ANSWER✔✔Delirium - acute and common
during hospitalization
Dementia - usually insidious and can be acute in situations such as trauma or stroke
What conditions are associated with delirium? - CORRECT ANSWER✔✔UTI, thyroid disorders,
hypoxia, hypoglycemia, toxicity, fluid-electrolyte imbalance, renal insufficiency, trauma, multiple
medications
What conditions are associated with dementia? - CORRECT ANSWER✔✔May have no other
conditions
What is the course of delirium? - CORRECT ANSWER✔✔Fluctuates and remits with treatment
