hi, mybabyjhay, and welcome to allnurses!
you have given us a nursing diagnostic statement of pain r/t decreased oxygen supply to tissues.
breaking this down it represents the following:
nursing diagnosis (patient problem): pain
related factor (etiology, or cause, of the problem): decreased oxygen supply to the tissues
first of all, you've got a big problem with the diagnosis and related factor here. if you will refer to a nanda nursing diagnosis reference you will find that you have diagnosed this incorrectly and the related factor you have listed is not an appropriate related factor for pain. you need to correct that. if this patient is, indeed, having a decreased oxygen supply to his tissues, then pain is not his main problem, and a different diagnosis is needed: ineffective tissue perfusion
and it will need to be related to some underlying pathophysiology of his/her disease process--not pain. pain is merely a symptom of the problem.
here are weblinks that have nanda information on the nursing diagnoses of acute
and chronic pain.
the difference between the two is the length of time that the pain has existed. read the definition of the two diagnoses very carefully before deciding which diagnosis to use. the patient will need to have symptoms of the pain. you will find symptoms (defining characteristics) of the pain listed on the websites listed below.
next, any nursing interventions must be based upon your patient's defining characteristics (signs and symptoms) of the pain. this is information that can only be obtained during your assessment and interview of the patient and collection of medical record data. you haven't listed any of that information in your post. so, there is no way i can intelligently give you specific interventions for this patient. only you know what the symptoms were that this patient was specifically experiencing. the links i posted above do have some nursing interventions listed on them. perhaps you will find some help in them. or, if you list your patient's symptoms of their pain i can help you with some interventions.
