I am surprised to read these responses because I've heard a lot of nurses say they never used 99% of A&P again after the courses were over. Maybe it depends on the school. I know our school was very heavy into the chemistry of the cell in A&P 1. We did a ton of work with how cells maintain the higher sodium outside of the cell and potassium inside the cell using the sodium potassium pump and then how the cell depolarizes allowing sodium influx, etc and so on during action potentials, etc. I'd be shocked if I ever used this in a real life nursing situation. But I'd be glad I used it since I learned if it came up LOL!!
PLEASE PLEASE know your A&P!!!! that is the heart and soul of nursing! Understanding it sets the stage for everything else to come(drugs, pathophys, treatments, etc.). Knowing that sodium is greatest outside the cell(in the ECF) and potassium greatest inside is absolute essential information that guides the treatment of cardiac conduction disorders, fluids and electrolyte disturbances, etc., which are major nursing responsibilities. The more you understand the better for your practice AND your piece of mind, because orders won't be such a mystery to you. That's not to say you HAVE to know every little fact. My suggestion is to review A&P the summer before you begin nursing classes. (Not fun, but so worth it). Sorry for the long post, I just wish someone had told me this before I started nursing school!
