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
|
What is the course with dementia? - CORRECT ANSWER✔✔-chronic slow decline
| | | | | | | | | |
What is the duration of delirium? - CORRECT ANSWER✔✔-Hours to weeks
| | | | | | | | | |
What is the duration of dementia? - CORRECT ANSWER✔✔-Months to years
| | | | | | | | | |
What sleep-wake cycle is noted with delirium? - CORRECT ANSWER✔✔-disrupted
| | | | | | | | |
