PNR 206 EXAM 3 2025 QUESTIONS AND
ANSWERS
Function of hypothalamus - ANS controls body temp, appetite, water balance, links nervous
& endocrine systems
Afferent - ANS carries impulses TO the CNS
Efferent - ANS carries impulses AWAY from the CNS
Cranial Nerves 1-6 - ANS I. Olfactory- Smell
II. Optic- Visual Acuity (afferent impulse)
III. Oculomotor- eye movement, dilation (efferent)
IV. Trochlear- Vertical Eye movement
V. Trigeminal-facial sensation
VI. Abducens-lateral movement of eyes
Cranial Nerves 7-12 - ANS VII. Facial- Taste
VIII. Auditory- Hearing & Balance

, tremor
bradykinesia (slow movements)
rigidity
pill rolling
mask like face
Peripheral Nervous System - ANS made up of sensory organs such as eyes, taste buds,
olfactory receptors, touch receptors
Sympathetic Nervous System - ANS fight or flight system
increase heartrate
increase blood pressure
increase sweating
pupils dilate
parasympathetic nervous system - ANS Pupils constrict
Relaxed state
everything remains normal or relaxed
Intracranial Pressure - ANS Normal ICP is 0-15
ICP greater than 20mm is emergent
Caused by swelling in brain, increase in CSH, swelling, increase in blood flow
Keep HOB between 20-30 degrees
Brain tissue is compromised
Vital Signs for patient with ICP - ANS Increased BP
Increase heartrate
elevated temp
