Q
  1. A 63-year-old African-American man is scheduled for right shoulder arthroplasty for degenerative joint disease. He has no history of infection, connective tissue disease, or tobacco and alcohol abuse. Laboratory studies drawn on the day of surgery show a leukocyte count of 2.2 X 109 cells/L (reference range, 4.5 X 109 cells/L). All other laboratory and presurgical evaluations are within defined limits. What is the best appropriate course of action?
  2. Perform the surgery after consultation with a hematologist.
  3. Perform the surgery because this value is not abnormally low for this patient.
  4. Delay surgery and immediately repeat the white blood cell count.
  5. Cancel the surgery because of the abnormally low white blood cell count.
  6. Cancel the surgery; a delay is needed to consider this value.
A
  1. Perform the surgery because this value is not abnormally low for this patient.

Q
  1. Figures 85a through 85c are the injury and reconstruction images of a 48-year-old man who had his right arm amputated 5 cm below his elbow by a machine. His postsurgical course is uneventful. He is pleasant in all interactions with those treating him. He is fitted with an dhas learned to use a myoelectric prosthesis. He is discharged from physical therapy with the evaluation that he is capable of returning to his job activities. The best next step should be to
  2. return him to work as soon as possible.
  3. evaluate independently his ability to use his myoelectric prosthesis.
  4. obtain a functional capacity evaluation and compare it to his job description.
  5. offer the opportunity to be evaluated by psychology before returning to work.
  6. recommend vocational rehabilitation because his prosthesis is too slow to use for work.
A
  1. offer the opportunity to be evaluated by psychology before returning to work.

Q
  1. A 25-year-old red-haired healthy woman with no history of substance abuse underwent fixation of a fractured distal radius under supraclavicular block but required an unusual amount of intravenous sedation and analgesia. Afterwards, she came to the emergency department in extreme pain. Compartment syndrome was ruled out; on maximum dose oral opiates, she improved over time. At her postoperative visit, she comes in with her red-haired mother, who related similar need for high dose pain medications. Examination is otherwise uneventful. What is the most appropriate course?
  2. Perform a drug test
  3. Question her drug and alcohol history
  4. Refer her to the pain service within a week
  5. Give her more high-dose pain medication
  6. Discuss a possible inherited lower pain tolerance

In addition to obtaining routine informed consent for this procedure, the physician should explain the material’s
