WOW ! $20.00 for a penlight.. Geez, I have a buttload of crap I can sell you, if your willing to purchase that type of stuff! ...
My advice is get a 50 cent disposable pen light, since after your clinical you'll never use it again, get a $10.00 cheap stethoscope, and a look for a used sphygmonometer for about <$10.00 and you are finished.
Put that extra cash $$ for books, and tuition on the next level, if you do proceed. Then when and if you finish paramedic school buy your self a nice medium price stethoscope that will have sentimental meaning and you will know what to listen to as well. You still will not use penlights except to find your car keys... I use the ambient light or a laryngoscope that is always handy.. if not I have 2000 watt spot light.. (just joking.. okay maybe not..lol)
Ask most EMT's what they are looking for with a penlight & they will respond PEARLA.. and then ask specifically what does that mean in relation to head injuries and overdoses ? Chances are they cannot answer... even Doc's no longer hardly look for PEARLA since >10 -20% population has anasocoria (unequal pupils).
When you are in ER most of them have free penlights from drug reps.. I am sure they might give you a few! ..
Good luck !
