Mrs. P is a 74-year-old woman presenting for emergent treatment of a
fracture-dislocation of her right hip, suffered in a fall at her nursing
home. She appears frail, but is alert and oriented. She is
accompanied by her daughter, and both state that they want her to
receive full medical care. On admission two hours earlier, the
emergency room physician heard a loud systolic murmur, and
echocardiogram revealed critical aortic stenosis, with a valve area of
0.3 cm2. The surgeon suggests that the patient, because of her
cardiac status and age, should have a DNR order in the chart.
