what is the most likely reason for a person to have abnormally high blood ammonia levels? This is a topic that many people are looking for. caraimica.org is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, caraimica.org would like to introduce to you Ammonia Nursing Considerations, Normal Range, Nursing Care, Lab Values Nursing. Following along are instructions in the video below:
This is a lab that youre gonna run often youre gonna see often often because it plays a very important role in understanding liver function. It can also a role in renal function. And then were also going to see it in in neuro function.
Okay so ammonia is incredibly interesting in its normal range for adults conventional units is 19 to 60 okay si units is 11 to 35 so you probably see conventional units is going to be 19 to 60. Now the reason. I think this is such an interesting lab value.
Okay is because it really plays a role in many parts in the body okay so ammonia is essentially the byproduct of protein metabolism okay so we intake protein that protein is then broken down into ammonia and then that ammonia is is converted basically in the blood to urea okay. So that ammonia turns into urea which is kind of a byproduct of also a protein metabolism okay so thats where we come up with blood urea nitrogen right and we use the blood urea nitrogen to determine renal function. But we use ammonia to determine liver function.
Okay so ammonia is kind of the the precursor to urea all right so does that make sense we take in protein protein turns into ammonia ammonia is then converted to urea and that urea is then excreted by the kidneys. If everything works appropriately so we take that one step back if our bu in is elevated. Then our kidneys are not able to excrete all that urea right for one example and so thats going to be a reason for our elevated bu in now we take that one more step back and if our ammonia is elevated then somethings happening within our liver our liver is not able to get that ammonia into urea and get it out okay so what are some reasons.
Were gonna see this elevated well. Its gonna be elevated in advanced liver disease okay so if we have issues like cirrhosis or hepatitis or issues that are affecting our liver. Then were gonna see elevated levels of ammonia right.
Were not able to make that conversion. Its also really helpful when we run this lab to check for a reason of hepatic encephalopathy. Okay.
Whats hap hadik encephalopathy well ammonia can be very detrimental to our central nervous system. If ammonia levels get high enough they can actually send the patient into very decreased neuro status. Okay so what will happen is well have to give like lactulose which will help us which will bind ammonia to stool okay and get it out through our gi tract and that will then bring down our ammonia levels.
And get the patient back to a normal functioning neuro status. Hopefully. So it can be helpful running ammonia to see okay are we getting to a hepatic encephalopathy.
Its also really helpful in monitoring treatment for hepatic encephalopathy is the treatment working an ammonia level can be really helpful also if four patients were receiving tpn. Where we can see okay how effective is this tpn. And and the the formula.
Were giving them now when we when we draw our ammonia lab. Its gonna go into a green top okay a 5ml green top tube and it needs to be sent to the lab on ice and the level needs to be run quickly okay we need to run this within like 20 minutes. Because ammonia levels can increase and a blood specimen okay so its important to put it on eyes.
Were good at to lab have it run very quickly so that we dont have falsely elevated ammonia levels. Okay thats a really brief overview of ammonia but what i want you to do and what i would suggest you do is you draw kind of the body and you draw protein coming in gets turned into ammonia gets turned into urea and kind of were failures in the system are going to occur to either cause your uri to be elevated or your ammonia to be elevated and understanding thats gonna help you understand liver disease as well as kidney disease. Okay.
Now i remember our ammonia level. Conventional units were looking for levels about 19 to 60 and our si units. About 11 to 35 in adult.
