A dialysis catheter is a catheter used for exchanging blood to and from a hemodialysis machine and a patient. The dialysis catheter contains two lumens: venous and arterial. This terminology is confusing, because both lumens are in the vein.
In order to practice as a dental hygienist, one needs a degree from a dental hygiene school and a state license. To become licensed, dental hygienists need to pass a clinical and written exam.
To become licensed in your state you will also need to pass a state exam regarding the laws and scope of practice and ethics for that state. Then you pay a fee of about $100 to $200 a year to maintain your license. Most states require that you do a certain minimum hours of continuing education each licensure cycle. It depends on the state you are in and the Dental Hygiene school you you attend. There is a shortage of dental hygienists so they have 2 and 4 year programs. However, be â¦ fore you check out a 2 year school, remember that there are prerequisits to getting into any program-even the 2 year programs.
