What your instructor said is right.
This is so true, but understanding the rationale for nursing interventions is VERY difficult for someone with little to no patient care experience.
I attended my nursing program as a 19-year old with absoutely NO healthcare experience. I am a very good memorizer, so I did well, but it wasn't until I had a year or two of actual RN experience under my belt before it all came together, and then memorization was no longer necessary.
I would suggest that you make certain you have a good understanding of the pathophysiology of any condition that you are being tested on. From there, move on to understanding the pharmacology of the medications involved. Then study pre-written care plans
and quiz yourself on the rationale for the nursing interventions suggested.
Do you still work in a nursing home? If so, ask your charge nurse to spend 5 or 10 minutes a shift with you discussing a patient whose condition you don't understand. Ask for permission to review the H&P, physician and nurse's notes, labs, radiology studies, and MAR. Try to formulate nursing diagnoses that apply to your patient's medical diagnosis (COPD, pneumonia, sepsis, etc.), and sketch out a brief care plan including rationales for your nursing interventions. It will get easier, and make more sense each time.
