NURS611 COMPREHENSIVE EXAMINATION
2026 COMPLETE QUESTIONS AND
CORRECT ANSWERS GRADED A+
◉ which system responds to stress by preparing the body to defend
itself.
Answer: Sympathetic nervous system (SNS)
◉ how is blood flow redistributed by the sympathetic nervous
system (SNS).
Answer: blood flow to the muscles is increased while blood flow to
GI and integumentary is decreased
◉ how are primary brain injuries classified.
Answer: focal or diffuse (aka multifocal)
◉ focal brain injuries.
Answer: specific, grossly observable brain lesions that occur in a
precise location
Epidural and subdural hemorrhages
◉ diffuse brain injuries.
, Answer: include brain injury due to hypoxia, meningitis,
encephalitis, and damage to blood vessels
The brain is confined in a limited space so increased pressure can
cause collateral dysfunction: Diabetes Insipidus (ADH not secreted
thus polyuria)
◉ autonomic hyperreflexia.
Answer: characterized by paroxysmal HTN (up to 300 mmHg
systolic), a pounding headache, blurred vision, sweating above the
level of the lesion with flushing of the skin, nasal congestion, nausea,
piloerection caused by pilomotor spasm, and bradycardia (30-40
beats/min)
◉ location of lesions in cases of autonomic hyperreflexia.
Answer: individual most likely to be affected have lesions at the T5-
T6 level or above
◉ sequence of events that lead to hyperreflexia induced bradycardia.
Answer: bradycardia (30-40bpm) is a sx of hyperreflexia
Stimulation of the carotid sinus -->vagus nerve -->sinoatrial (SA)
node. The intact ANS reflexively responds with an arteriolar spasm
that increases blood pressure. Baroreceptors in the cerebral vessels,
the carotid sinus, and the aorta sense the HTN and stimulate the
PNS. The heart rate decreases, but the visceral and peripheral
