 Welcome to Nursing School explain in this video on using the pain assessment tool or acronym OPQRST for assessing a patient's pain. So O stands for onset when the pain start, P for provoked what caused it, Q is quality, so what does the pain feel like? This is when it will be sharp, dull, achy, crampy, any of those describing factors. And R can have three different meanings so relieving factors what makes the pain better, radiation, radiating to other parts of the body from the original part that causes the pain and then the region so what is the original part or where is the pain located. S stands for severity that's our tool of 0 to 10 scale and then T can stand for treatment try so what has the patient tried at home or with non-pharmaceutical measures to make the pain better or time. Now if you leave out the O onset then you should really address the T time over here but if you include the O in the whole OPQRST acronym then you already have the onset covered here and you could literally leave out the time because it already encompasses all the different things and aspects that we need to look at in the pain assessment. Please also check out the other example about the other acronym old cards which is similar but different and you can just figure out which one works better out for you and then also check out the other video where I give an example of where you could use it in report to give the report about the patient's pain to another health care provider. Thanks for watching.
