[FONT=Arial Narrow]Hi everyone!
I was just wondering if you guys can tell me how much information relating to nursing changes over the years. I ask because I am going to be starting school March 8th and I am HOPEFULLY going to end up in the nursing program (ASN/RN) soon. My grandmother-in-law gave me her old books (she is an LPN) and they seem to have a lot of information, but I was wondering how accurate they are, and how much stuff changes. I thought they were great and what a wonderful gesture, but since they are like 20+ yrs old, is it a bad idea to keep them? I just don't want to start reading stuff in them now and then have "learned" the wrong things.

I bought some old nursing books on ebay a couple of years ago. Very interesting reading!!
I know this is an extreme example, but in a section of one book (Medical Nursing by Hull, Wright and Eyl. copyright, 1940) it describes "special Methods of Examining the Circulatory System." There is a test to measure blood velocity, or the speed which blood is flowing.
The procedure, which was called the "arm to tongue" circulation time went like this:
The nurse injects saccharin into a vein at the elbow, and has the patient say "sweet" the instant he detects a sweet taste in his mouth. The interval of time (measured with a stop watch) between the injection and detection of the sweet taste is a measure of the time required for blood to flow from the arm, through the right "auricle" and ventricle, the lungs, back to the left side of the heart, and up to the capillaries of the tongue. This usually takes 10-15 seconds. Sometimes ether is injected to determine the "arm to lung" circulation time, which is determined by the time which elapses before the patient smells the ether.
It goes on to say that "recently" calcium gluconate was being used to measure the "arm to tongue" time, "the end result being a sensation of heat in the throat."
Yikes! This is a parameter expressing the pressure exerted by the blood on the vessel walls. Knowing this value in vascular medicine/surgery is important to establish the state of the vessels which directly relates to vascular diseases.
These days we use noninvasive Doppler Ultrasound.
I LOVE these books!
