NURS 403 - LAST EXAM OF NURSING
SCHOOL COMPLETE QUESTIONS WITH
100% VERIFIED ANSWERS
\Q\.What are the four lobes of the brain? - ANSWERS✔-Frontal
Parietal
Temporal
Occipital
\Q\.Where is the frontal lobe located & what is it responsible for? - ANSWERS✔-Front of the
brain
Motor movement and personality
\Q\.Where is the parietal lobe located & what is it responbile for? - ANSWERS✔-Behind frontal
lobe & above temporal lobes
Sensation & Perception
\Q\.Where is the temporal lobe located and what is it responsible for? - ANSWERS✔-Side of the
brain, below parietal lobe and posterior to frontal lobe.
,Sound recognition, speech, (Brocas and Wernickes area) and short term memory
\Q\.Where is the occipital lobe located and what is it responsible for? - ANSWERS✔-Posterior
portion of the skull behind all other lobes
Vision
\Q\.What does the brainstem consist of? - ANSWERS✔-The pons, medulla, and midbrain
Basic functioning occurs and all motor/sensory information is relayed. 10/12 cranial nerves sit
here
Midbrain processes auditory and visual signals
Medulla controls HR, RR, BP
Pons controls RR / sleep-wake cycle
\Q\.Where is the cerebellum located and what is it responsible for? - ANSWERS✔-Its located
inferior to the occipital lobe. It is responsible for coordination of movement.
Issues with this will result in problems w/ gait, unsteadiness.
\Q\.What is the cerebral perfusion pressure? - ANSWERS✔-Pressure neeedd to ensure blood
flow to the brain
,Normal CPP is 60-100mmHg
Less than 50 will result in ischemia to the brain
Less than 30 is incompatible with life
Formula for CPP is MAP - ICP = CPP
\Q\.What's a normal cerebral perfusion pressure? - ANSWERS✔-60-100 mmHg
\Q\.What's the formula for Cerebral Perfusion Pressure (CPP)? - ANSWERS✔-MAP - ICP = CPP
Should be between 60-100 mmHg
\Q\.What is autoregulation? - ANSWERS✔-the ability of tissues to regulate their own blood
supply despite changes in perfusion (either constrict or dilate)
\Q\.What are the layers of the meninges? - ANSWERS✔-dura mater (top)
arachnoid mater (middle)
pia mater (closest to brain)
\Q\.Where is an epidural hematoma? - ANSWERS✔-Between the skull and the dura mater
*Emergent* - requires surgery to save their life
\Q\.Where is a Subdural Hematoma? - ANSWERS✔-between dura and arachnoid space
, Often associated with *venous* injuries
\Q\.Where is a subarachnoid hemorrhage? - ANSWERS✔-Between the arachnoid mater and pia
mater
Often associated with *aneurysms*
\Q\.How would intracranial pressure (ICP) be defined? - ANSWERS✔-The hydrostatic force
measured in the brains compartments / pressure in the head.
\Q\.What is a normal ICP reference range? - ANSWERS✔-0-15 mmHg
\Q\.At what ICP level would you intervene for treatment? - ANSWERS✔-If the ICP is greater than
20 mmHg
\Q\.What is the Monro-Kellie Doctrine? - ANSWERS✔-idea that the head is a closed shell and
the three major components (brain, blood, and CSF) are in a state of dynamic equilibrium
- as the volume of one goes up, the volume of another must go down
This compensatory mechanism can only go on for so long.
\Q\.What are the 3 components of the Monro-Kellie Doctrine? - ANSWERS✔-Brain
Blood
CSF
