NUR 611 EXAM 2
NUR 611 EXAM 2 QUESTIONS AND ANSWERS GRADED A+
What makes up the autonomic nervous system? ANS >> Sympathetic
and parasympathetic nervous system
What is the parasympathetic nervous system responsible for? ANS >>
Conserving energy and the body's resources
What is the sympathetic nervous system responsible for? ANS >>
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? ANS >> Focal or
diffuse
,NUR 611 EXAM 2
What are focal brain injuries? ANS >> Specific, grossly observable lesions
that occur in a precise location
What are examples of focal brain injuries? ANS >> Epidural
haemorrhage and subdural haemorrhage
What are examples of diffuse brain injuries? ANS >> Hypoxia,
meningitis, encephalitis, and damage to blood vessels
What can happen with increased intracranial pressures? ANS >>
Collateral dysfunction such as Diabetes Insipidus
What are characteristics of autonomic hyperreflexia? ANS >>
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? ANS >> Stimulation of the carotid sinus nerve to the
sinoatrial nose
The intact autonomic nervous system reflexively responds with
arteriolar spasm that increases blood pressure
, NUR 611 EXAM 2
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 is the onset of delirium and dementia? ANS >> 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? ANS >> UTI, thyroid
disorders, hypoxia, hypoglycaemia, toxicity, fluid-electrolyte imbalance,
renal insufficiency, trauma, multiple medications
What conditions are associated with dementia? ANS >> May have no
other conditions
What is the course of delirium? ANS >> Fluctuates and remits with
treatment
What is the course with dementia? ANS >> chronic slow decline
