How To: Perform a general neurological exam on a patient

As a doctor, sometimes it will be necessary to perform a neurological examination of your patient to rule out any neurological disorders. Your objective is to identify abnormalities in the nervous system, to differentiate peripheral from central nervous system lesions, and to establish internal consistency. This is a great video less that outlines the complete neurological exam procedure. It's great for medical students or doctors, and even nursing students can learn a thing or two.

How To: Prevent a car from start to test the starter

In this tutorial, we learn how to prevent the car from starting to test out the starter. The most simple way to do this is to open the hood of the car up and find the fuse locations from the owner's manual. Pull the fuses out and when you try to start the car, it will crank but it will not be able to start. You can use this to test out the battery and test the starter. When finished, remember to replace the fuses back into the car just how you removed them, then restart your car to make sure ...

How To: Perform a brief neurological exam on a patient

A brief neurologic examination includes six sections: 1) mental status exam, 2) testing cranial nerves, 3) sensation exam, 4) testing strength, 5) deep tendon reflexes exam, and 6) coordination exam. Eve Bargmann, M.D., shows doctors how to perform this neurological examination on a patient. You will need to do a full neuralgic exam (not in video) if any abnormalities are found. But this is just a brief screening exam during a general physical exam.
