rationale is nothing more than an explanation, justification or principle behind why you have put the particular nursing interventions on your care plans. depending on the situation the patient is in, your interventions are always going to follow the symptoms or problems the patient is having. in order to do this you need to make a list of the patient's problems that you are wanting to address. then, you need to do a little research about them using your textbooks and any other sources you might have, including the internet. don't forget to include what the doctors might want to be ordering as well as tests. by doing this, you will be able to better establish the priority of what needs to be attended to. remember that your ultimate goal is always going to bring the patient back to some sort of normalcy or acceptable level of functioning so the nursing interventions you choose are always going to ultimately be aimed to that. you will find the rationale for your interventions buried within that kind of logic. all you have to do is find that rationale in writing in order to verify that your intervention follows good principles of nursing. you have to do some of this leg work in order to develop a good rational plan of care. the various parts of the care plan then fall into place with one exception. that, for most of us, is the development of the nursing diagnostic statement which is a labor of english composition. you will need to have a current list of the nanda nursing diagnoses to refer to if that is what your instructors are requiring, or an explanation of how to write that diagnostic statement. all the rest of the nursing care plan is based on anatomy, physiology, pathophysiology and nursing care principles whose textbooks you should already have in your possession.
i also would recommend that you bookmark the following web site: family practice notebook.com. http://www.fpnotebook.com/
this is a huge database. the easiest way to find information on this site is to just do a search of that site for a particular problem (medical diagnosis) or symptom. the search box is in the upper left of the page just below their logo. play around with it while you're on vacation. do a search for some problems like diarrhea or seizure and see what comes up. sometimes it will present you with more specific links to check out. you will often end up with a page that outlines description of the problem, causes, pathophysiology of it, diagnostic tests and complications. although this site is for doctors, it is helpful for nursing because it gives us an idea of what the doctor is going to be doing for the patient and helps us tailor some parts of our care plan to those things which we may not have considered before.
-- this site has been designed as a single resource where people can find up-to-date lab testing information vital to the understanding and management of their health, or the health of someone close to them. it includes test descriptions, conditions, screening guide and current news. when looking up disease conditions, the lab tests typically ordered for them are listed with links to explanations about them. make sure to check out their site map for more information about lab services.
i also suggest that you read through the sticky's on these 3 forums: general nursing student discussion forum, nursing student assistant forum and pre-nursing student forum for all kinds of links to internet resources that you should check out during your school break. bookmark the ones you think will be helpful for you. also, post to the forum when you have a question on something. just make sure the title of your post attracts attention as to the subject involved as this one did for me.
