hi, margaretptz! yes, this is doable. i've looked over the guidelines for the nursing process assignment that you attached to your post. this is merely the nursing process, specifically directions on how to write a care plan. i think you will find some ideas and help by going through some of the posts in these two threads:
i often find that one of the moderators adds replies that i give on writing care plans
to these threads. if you have a care plan or nursing diagnosis book
the very first chapter or two usually details the nursing process as it pertains to writing care plans.
the first step always involves collecting data. this includes not only your physical assessment but all the data you can collect from the patient's written record. in the absence of that, you look to the signs and symptoms that normally accompany a medical diagnosis. nurses are also able to use the same signs and symptoms of a medical diagnosis (not the medical diagnosis itself) to determine their nursing diagnoses and develop their nursing problems and nursing interventions. i see that in part a your instructors have underlined "and abnormal findings in each category" in item #1 under assessment data. the reason is that it is the abnormal findings, or in nanda language "defining characteristics", that help to define each nursing diagnosis. those abnormal findings are what you are grouping together when you are doing your data cluster assessment. those groupings, or data clusters, or abnormal findings, are actually defining characteristics that match with specific nursing diagnoses. the trick is in knowing what abnormal findings cluster to which nursing diagnoses. the way you determine that is by having a book of nursing diagnoses to use as a reference that lists this information. i think your instructors could have been a lot clearer in putting this information together on this guideline, but that is just my opinion and probably why i end up answering a lot of care plan questions. i try very hard to put this stuff in simpler language that students can understand.
as calla2114 has suggested pick a medical disease that fits your fancy. you'll need to look up information about the disease itself and probably some of the pathophysiology since part b, section i of your guideline is asking for this. you also need to find out what tests the doctor normally would order to determine the presence of the disease and monitor it's progress. you'll need to know the signs and symptoms of the disease because these will become your abnormal findings which you will divide into clusters that will become the defining characteristics of your nursing diagnoses. these defining characteristics will also help you to determine your short and long term outcomes.
you can use family practice notebook to get the thumbnail pathophysiology and, most especially, the diagnostic tests and medical treatments that are normally done for the various medical diseases. i would suggest you not pick something too complex like diabetes (has too many complications) or a heart problem. this is the site. use the search box to find a disease.
at these websites you can link in to a whole bunch of student case studies that will give you an idea of how these are written up. it might also give you an idea for a disease to pursue:
these care planning exercises will give you an idea of how the nursing process is used to develop a care plan:
if you still need help, please ask. the first care plans generally take a lot of time to write. the important thing is that you understand what goes into the steps of the the process. happy care planning!
