Hello Bert! I'm a Practical Nurse and a senior on the BSN program, and let me tell you, it didn't start to really click until this year on the clinical floor. And there is still so much more to learn! Keep in mind that you are given huge amounts of information that will apply to several different areas of nursing to 1. give you basic knowledge and flexibility to choose various areas in the nursing field and 2. pass the NCLEX. But in my experience as a Practical Nurse, what you will know like the back of your hand is the information pertinent to where you work. If you work in med-surg, you will not remember anything about pediatric nursing, and so on. So, stay encouraged! Honestly, my response to my family anymore (after years of taking health related questions!) is "you should make an appointment with your doctor" lol.
