They may experience irritability and depression because when a person constantly smokes, his/her brain begins to rely on the chemicals it gets from the person smoking, which results in the brain "getting lazy" and not producing the chemicals anymore. If the person were to suddenly quit, the brain would lack in the chemicals it had stopped producing, making the person feel constantly annoyed and depressed because of the chemical imbalance.

Hi,
The first step to become a registered nurse is to successfully complete an accredited nurse program in the category of diploma, associate degree or a bachelor’s degree. The second step is to sit and pass the NCLEX-RN exam with a mark of over 70%. This should be followed by obtaining a state license that varies from state to state. Fourth, a person should be employed and start practicing as a registered nurse. Lastly it is advisable that after obtaining the registration, a nurse should pursue additional training and education.
Best wishes!
