How would you examine a patient?
Cardiorespiratory - assess for respiratory/heart failure
Abdomen - palpate for masses, enlarged kidneys, distended bladder, DRE exam
Mental state - perform a cognitive assessment
Pelvis - check for vaginal trophy or prolapse, assess pelvic floor muscle strength, assess for stress incontinence
Neurological - assess gait, look for clues to neurological diagnosis, check dorsiflexion of the toe, check perineal sensation, sensation of the sole, posterior aspect of the thigh
