Answer to Question 1
A
Because of the lifesaving modalities needed to care for such a patient, the nurse and physician work together to determine what the patient's end-of-life wishes are. In the emergency depart-ment, patient stabilization comes first, but once this has been accomplished a discussion should occur with the patient and family about further treatment desires. The family caregiver may or may not be adherent, or the patient may assume all self-care. IV fluids should not be given at a rapid rate because of the risk of heart failure.

Answer to Question 2

Major complications after joint replacement surgery include thromboembolism (deep venous thrombosis DVT), joint or wound infection, blood loss, nerve injury, joint dislocation, and sur-gical pain. The risk of DVT is highest between the first and second week after surgery. An in-crease in calf circumference can indicate the presence of a DVT. The other assessments are ap-propriate but not as critical.
