ADH is a hormone from the posterior pituitary that tells your kidneys to hold onto water. It kicks in when blood gets too concentrated or blood pressure drops, and shuts off when volume is high. Nursing students need this for understanding fluid-electrolyte balance.
In this video, we are going to break down exactly what ADH is and what you need to know about it for nursing school. And before we get started, be sure to subscribe to this channel and click the little bell so you don't miss out on any other videos to help you totally rock nursing school. Now let's do it. What is up? My friend Christina here with nursingschoolofsuccess.com and today in this video we are talking all about anti diet hormone or adh. So antidiuretic hormone, otherwise known as adh, does exactly as it sounds. It's an antidiuretic, meaning it's going to help the body retain water. What happens when you give a patient a diuretic medication? They urinate a lot. And ADH is antidiuretic hormone. So it's basically the reverse of that. They will hold on to water rather than get rid of it. Now, ADH is a hormone that is secreted by the hypothesis thalamus in the brain. And there are really four things that I want you to know about adh. Its whole job is to keep water and fluid inside the body. It's secreted when there is electrolyte levels in the blood get too concentrated because of a low blood volume. It's secreted when the blood pressure decreases because of low blood volume. And it's inhibited when the blood volume or the blood pressure is high. High. So the body wants to constantly stay in balance. Right? That's its comfy zone homeostasis. It's always trying to stay in balance. So it wants to have a nice balance of fluid and electrolytes. However, when the electrolytes get too concentrated, the body wants to balance that out by adding more fluid. So if the electrolytes are too concentrated, ADH will be released because ADH will go tell the kidneys to hold on to water, which will then increase the fluid volume and dilute out those electrolytes in the same way, if the fluid volume is simply just low, ADH will be triggered to help increase that fluid volume. Now on the other hand, if the fluid volume in the body is too high, the ADH level will decrease because ADH is antidiuretic hormone. So if the fluid volume is too high, the body wants to get rid of that fluid. It wants to diurese and get that excess fluid out. So if the so blood volume is too high, the ADH level will go down. Does that make sense? I like to think that you're nodding your head with me as I go through this so if this is all just clicking for you, write love in the comments below so that I know that this all makes sense for you. Okay, so if the fluid volume is low or the electrolyte levels are high and concentrated ADH will spring into action and help the kidneys hold onto water. However, if the fluid volume is too high already, ADH will be inhib so the kidneys can just do their thing and get rid of some of that excess fluid. And that my friend, is the role of ADH in the body and how it balances out fluids and electrolytes. Now if you want more help with fluids and electrolytes in nursing school, you will definitely want to check out the fluid and electrolyte course that we've got for you inside of the Nursing SOS Membership community. There is a link down below in the description for you to check out all of the details if you're interested. Thank you so much for watching friend as always. Now go become the nurse that God created only you to be and I will catch you right back here next time on the Nursing School Show. Take care of.
