CNA is short for a Certified Nursing Assistant. These poor employees are typically the hospitals bitch. They are responsible for doing all of the petty and annoying tasks that the real medical professionals don't have time for. They are usually single moms and douchebag guys that failed out of nursing school or aren't smart enough to get into an advanced medical program. Qualifications are as follows: (Girls) At least two kids from separate daddy's, a neck or wrist tattoo (bonus points for both), and a nose ring. (Guys) Fake diamond earring, non-existent girlfriend, a bad tribal tattoo that your homeboy did in his garage. You must be a smoker and have an unreliable car that you will use as an excuse for multiple call-outs. Lastly, you must have a sense of entitlement toward your job. In other words, you must have the attitude that your job is actually important. We all know its not, but if you think it is then that's all that matters.
Patient: "Hey, can you get me some graham crackers? And after that, I need you to clean me up. I just took a major shit all over the bed."
Nurse: "Hold on, I'll get the CNA."
