Of course I assess my patients at the beginning of every shift. I listen to their heart, lungs, abdomen; check their pulses; check for edema in the lower legs/feet ans ask them about last bm. Then I focus in on their problem area (why they are in the hospital). If I have a 50 year old that's in with COPD exac., I will focus on their lungs (listen front and back from top to bottom of lungs, ask about coughing (productive/nonproductive), do they get SOB when getting OOB? ....). I won't check the pupils on a pt. like that.
If a pt. is in with TIA, r/o CVA, I won't listen to their lungs front and back from top to bottom, I also won't be asking him about coughing. Instead I will be doing neuro checks.
