Med Surg II - Quiz 2 Questions and Verified
Answers
CNS Correct Answer: Brain and spinal cord
PNS Correct Answer: Somatic and Autonomic
spinal nerves - 31 pair
cranial nerves- 12 pair
Somatic Correct Answer: voluntary
Autonomic Correct Answer: ***involuntary - performed at an unconscious level
Primary function is to maintain internal homeostasis - normal HR, normal respiration pattern, and
constant body temp***
made up of sympathetic - fight or flight
and parasympathetic - rest or digest
Acetylcholine, norepinephrine, dopamine, and serotonin are all examples of ________. Correct Answer:
Neurotransmitters
Nerve I and it's function Correct Answer: Olfactory - Smell
Nerve II and it's function Correct Answer: Optic - Vision (acuity and field of vision); pupil reactivity to
light and accomodation (afferent impulse)
Nerve V and it's function Correct Answer: Trigeminal - Chewing; facial and mouth sensation; corneal
reflex (sensory)
Nerve VII and it's function Correct Answer: Facial - Facial expression; taste; corneal reflex (motor) ;
eyelid and lip closure
Nerve X and it's function Correct Answer: Vagusb - Gagging and swallowing(motor); speech (phonation)
**Serves organs in the thoracic and abdominal cavities**
, Parts of NORMAL aging...not alzheimers Correct Answer: Decrease in body temp regulation
Altered sleep and wakefulness
**Loss of brain weight 1% per year after 50**
Older adults Correct Answer: Neurologic function deteriorates - slowed reflex/reaction time
Tremors that increase with fatigue are common
Sense of touch and fine motor coordination diminish
Speed of learning is slowed - short term memory is more affected than long term.
incidence of physiologic dementia increases with age
incidence of stroke increases with age
Nerve irritation from arthritis , joint injuries or spinal cord compressin can cause chronic pain or
weakness.
DEMENTIA is NOT a normal consequence of aging - may be result of a variety of other reversible
conditions
Categories of the glascow coma scale Correct Answer: Eyes Open
Best Verbal Response
Best Motor Response
15 is the best score - 8 or less - definition of coma
Frontal lobe is responsible for Correct Answer: written speech; ability to write
An injury to Broca's results in Correct Answer: Expressive aphasia
An injury to Wernicke's results in Correct Answer: Receptive aphasia
Proprioception Correct Answer: Spacial awareness
