we just started the second semester of 5 on monday, well we have our first test on tuesday iv therapy and the dreaded fluid and electrolytes
my question is for all of you who have taken the course; is there a simple way to remember the normal lab values, and how did you learn your abg's???
it kinda makes you wonder what semester three, four and five are going to be like, doesn't it?
the only way to remember this stuff is to hunker down and work at it. try to do it in short sessions. if making lists or tables (of the the normal abgs and respiratory/metabolic acidosis/alkalosis) helps you in some way, then do it to help you learn it. i'm listing a whole bunch of internet links to this information as well as some older allnurses threads that i thought had some good information you could use.
you are going to see the mnemonic rome used to describe respiratory and metabolic acidosis and alkalosis in some of the allnurses threads. this is what that mnemonic means:
the mnemonic rome means the following
- ph elevated pco2 diminished = alkalosis (respiratory)
- ph diminished pco2 elevated = acidosis (respiratory)
- ph elevated hco3 elevated = alkalosis (metabolic)
- ph diminished hco3 diminished = acidosis (metabolic)
make sure you check http://allnurses.com/forums/f205/pat...es-145201.html
the pathophysiology/ a & p/ fluid & electrolyte resources thread on the nursing student assistance forum (it's a sticky). some of the links below may also be listed in that thread.
- the abg site. how to accurately interpret arterial blood gases from ed4nurses.
- this is an abg and acid/base balance tutorial. you do not have to register to go through the tutorial.
- "interpretation of abgs: the battle of bicarb vs. carbon dioxide
- an abg and abg analysis tutorial by a nursing instructor at indiana state university. http://www-isu.indstate.edu/mary/abgpract.htm
- this is a quiz to test what you learned (includes answers).
- "interpretation of abgs: a four step method". from rnceus.com. discusses the authors four step method for interpreting abg values along with patient case studies and examples.
- blood gas basics from mad scientist software
- abg tutorial from butler community college nursing program. includes questions and case scenarios. not sure if all answers to questions are on the site.
- this is an abg review. it has 20 sets of abgs for you to interpret. the answers are at the bottom of the page.
- blood gas analysis downloadable pamphlet of normal abgs parameters and brief explanation of abnormal results and what they can mean. great to put on your clipboard!
- the home page of an interactive acid-base tutorial for medical students by professor alan grogono at tulane university, but there are things in it that are useful for nursing students. click on buttons throughout the presentation for more specific information. you might want to click on the "alphabetical index" at the left side to get a listing of the subjects covered on this site to save time. also, check out the "links" for more acid-base tutorial sites.
- acid-base balance by professor michael j. bookallil from the royal prince alfred hospital of the university of sydney. includes information on respiratory/metabolic acidosis and alkaloses as well as their treatment and conditions related to them: cardiac arrest, and ketoacidosis
- a one page chart showing compensated and uncompensated metabolic and respiratory acidosis and alkalosis
- body fluids, electrolytes and ph balance. a very nice presentation from a professor at st. petersburg college. there are links at the top of the page to an a&p textbook online learning resource (check out the weblinks), sample quizzes (for that particular instructor) and internet tutorials. nice review of fluid of electrolytes!
- a slide show presentation on fluid and electrolytes. covers sodium, potassium and calcium and treatment including iv fluids.
- this is the home page for the above site. the link to the above is at the bottom of this page. there are more links there to information on fluids and electrolytes including lecture note outlines
- thumbnail sketches of lab values, signs and symptoms of increased and decreased levels of the following electrolytes: sodium, potassium, calcium, magnesium. also includes glucose, respiratory and metabolic acidosis and alkalosis, and arterial blood gas values.
- a fairly thorough explanation of hyperkalemia from medicinenet.com
- here's everything you could possibly want to know about hypercalcemia from an online medical textbook. this is just an overview page. there are lots of links to more specific information if you dare to look!
- here's everything you could possibly want to know about hypocalcemia from an online medical textbook. this is just an overview page. there are lots of links to more specific information if you dare to look!
- "maintaining the internal seas in harmony: common electrolyte disturbances in the ed" good discussion of dehydration and sodium and potassium electrolyte disturbances. includes discussion of how they occur, signs and symptoms, labs, as well as nursing actions
