NUR 611 Exam 2 Questions And Answers
2024-2025
What is part of the autonomic nervous system? - ANSWER Sympathetic and
parasympathetic nervous system
What does the parasympathetic nervous system do? - ANSWER Conserve energy and
the body's resources
What does the sympathetic nervous system do? - ANSWER Catecholamine release -
Epinephrine
Mobilize energy stores and decrease release of insulin
Redistribute blood low - Increase to muscles and lungs (flight) and decrease to
GI/Integumentary
What are the categories of primary brain injury? -ANSWER Focal or diffuse
What is considered a focal brain injury? -ANSWER A discrete, grossly identifiable lesion
that is located at a precise site
What are some examples of focal brain injuries? -ANSWER Epidural hemorrhage and
subdural hemorrhage
What are some examples of diffuse brain injuries? -ANSWER Hypoxia, meningitis,
encephalitis, and blood vessel damage
, What can happen with increased intracranial pressures? -ANSWER Collateral
dysfunction such as Diabetes Insipidus
What are manifestations of autonomic hyperreflexia? -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 the bradycardia caused by hyperreflexia?
-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? - ANSWER Delirium - acute and common
during hospitalization
Dementia - generally insidious and may be acute in conditions such as trauma or stroke
What diseases are associated with delirium? - ANSWER UTI, thyroid disorders, hypoxia,
hypoglycemia, toxicity, fluid-electrolyte imbalance, renal insufficiency, trauma, multiple
medications
What diseases are associated with dementia? - ANSWER May have none
