Each of the following statements is true of Parkinson's disease except: - ✔✔ANSWER✔✔->>>>>>>>It is characterized by an increase of dopaminergic neurons Efferent neurons deliver input from the CNS to the periphery. - ✔✔ANSWER✔✔->>>>>>>>Motor SRIs the reuptake of serotonin at the presynaptic space. - ✔✔ANSWER✔✔->>>>>>>>inhibit is sleep disordered breathing due to the brain not properly signaling the respiratory muscles. - ✔✔ANSWER✔✔->>>>>>>>Central sleep apnea utilizes electric impulses to inhibit or stop the abnormal nerve activity that causes tremor and other unwanted movement patterns associated with Parkinson's disease. - ✔✔ANSWER✔✔->>>>>>>>Deep brain stimulation Specialized ependymal cells that project into the ventricles and produce CSF are called the. - ✔✔ANSWER✔✔->>>>>>>>Choroid plexus Schwann cells produce myelin in the CNS. - ✔✔ANSWER✔✔->>>>>>>>False, Schwann cells produce myelin in the PNS.

True

Vital signs increase during stage 1 of NREM sleep. - ✔✔ANSWER✔✔-

False, vital signs decrease during stage 1 of NREM sleep. Someone in the early stages of Alzheimer's disease requires assistance for their activities of daily living. - ✔✔ANSWER✔✔->>>>>>>>False, in the early stages of Alzheimer's disease, individuals are still independent with their ADLs. Explain how a chemical synapse produces an excitatory or inhibitory signal. - ✔✔ANSWER✔✔->>>>>>>>The presynaptic neuron will secrete neurotransmitters which diffuse into the synaptic cleft and bind to excitatory or inhibitory receptors on the postsynaptic membrane eliciting an excitatory or inhibitory signal in one direction. You are babysitting a 7 - year-old child with a known history of seizure activity. You notice they appear flushed and seem unresponsive. You ask if they are feeling alright and they stare at you blankly. After a few seconds they act as if nothing happened and return to play. Is this a generalized or focal seizure? Based upon this description, what specific type of seizure did this individual experience? - ✔✔ANSWER✔✔->>>>>>>>Generalized, Absence seizure Compare and Contrast breathing patterns between NREM and REM sleep (include a discussion on the specific stages of NREM sleep.) - ✔✔ANSWER✔✔- In stages 1 and 2 NREM sleep as well as in REM sleep, breathing is irregular, and brief periods of apnea are often observed (approximately 5 - 15 seconds.) During stages 3 and 4 of deep sleep, breathing becomes regular. A patient reports to the emergency department where you are working at 10 False, in the early stages of Alzheimer's disease, individuals are still independent with their ADLs.

During stages 3 and 4 of deep sleep, breathing becomes regular. A patient reports to the emergency department where you are working at 10 pm. They report that earlier in the day beginning at approximately 9 am they began to experience tingling in their right arm. They decided to ignore it thinking it was probably a result of all the gardening they did the day before. As the day

went on, the tingling sensation got worse, and they started to have difficulty speaking. The patient's spouse reported that they were slurring their words. Past medical history includes a diagnosis of diabetes and hypercholesteremia. By the time they are evaluated, their symptoms start to subside. The tingling disappears and their speech returns to normal. What do you suspect this patient has experienced? What evidence is there to support that diagnosis? - ✔✔ANSWER✔✔->>>>>>>>This patient has experienced a TIA. They have experienced symptoms consistent with oxygen deprivation to the brain, however their symptoms subsided within 24 hours of their onset. A 75 - year-old male is brought to the emergency department by their spouse at 8 pm. The spouse reports that they were cleaning up after dinner at approximately 6:30 pm, and she noticed that her husband's speech was very unclear. When she asked him what was going on, he said that he didn't know and that the entire right side of his face felt numb.

How would you confirm this diagnosis? What treatment should be administered? Explain why you chose that treatment. - ✔✔ANSWER✔✔->>>>>>>>This patient is more than likely experiencing an ischemic stroke. A CT scan and MRI would be needed to determine if a clot was blocking blood flow to the brain tissue and to rule out a hemorrhagic stroke. If a clot is found, this patient should receive tPA drugs as they are within the 3 - 4.5 hour treatment window. You are seeing a patient in your office with a primary complaint of excessive daytime sleepiness. Their spouse reports that they snore loudly and often wake up gasping for air. What type of sleep disorder do you suspect they are experiencing (be specific)? What type of diagnostic work up needs to be done? Name one treatment option to address this patient's symptoms. - ✔✔ANSWER✔✔-

This pt is experiencing Moderate/ borderline severe Obstructive Sleep apnea, we need to see if he has any of the potential risk factors like large neck girth, obseity, male, etc. the pt needs to go under extensive sleep studies to confirm their OSA diagnosis. depending on the severity, life style changes can help
