GrnTea is right...you need to have a good nursing care plan book and/or NANDA-I book to make you life SO much easier! I use Ackley and Ladwig, Nursing Diagnosis Handbook as well/
However........Deficient knowledge (specify) is a NANDA-I diagnosis......and a good one.
Absence or deficiency of cognitive information related to a specific topic
Exaggerated behaviors; inaccurate follow-through of instruction; inaccurate performance of test; inappropriate behaviors (e.g., hysterical, hostile, agitated, apathetic); verbalization of the problem
Related Factors (r/t)
Cognitive limitation; information misinterpretation; lack of exposure; lack of interest in learning; lack of recall; unfamiliarity with information resources
OP remember that nursing care plans are all about the assessment of the patient and what the patient needs first according to Maslows Hierachy of Needs .....or whatever theory you use
So looking at what information you gave.....
patient had a femoral fracture and it was her third day post op. She complains of nausea so i gave her gravol. She also reports pain 6/10 on her left hip (related to her surgery for femoral fx) and she asked me why it was so important to mobilize and do physical exercise. This is one of my dx (deficient knowledge about mobilization as evidenced by the patient doesn't want to get out of the bed) i am not really sure it is a good diagnosis. it was also the first time I was giving Lovenox subcu and i was really stressed at first but once it is done, i will never forget how to give meds. The book we are using at college is med-surg nursing in Canada (cause i am from Canada). So i have to write down 2 nursing diagnosis/priority for my patient. the first one would maybe be acute pain related to surgery for femoral fracture as evidenced by rating the pain 6/10. the second one would maybe be the deficient knowledge about mobilization.
I have highlighted important information. Look at the priority of needs.....so what is most important to this patient. She has Acute Pain
, complains of Nausea
(yes a NAND-I diagnosis) , she has Deficient knowledge
) about mobility that makes her Fear
ful of ambulation.
