1. You perform thromboelastography for your hemorrhaging patient who has
sustained massive abdominal trauma and it reveals a prolonged R time. Which
of the following is an appropriate initial therapy to manage the patient’s
suspected coagulopathy?
A. Platelets
B. Fresh frozen plasma
C. Tranexamic acid
D. Cryoprecipitate
E. Packed red blood cells
2. A 26-year-old patient with autoimmune thrombocytopenic purpura and a
platelet count of 51 000 per microliter is scheduled for urgent appendectomy.
Which thromboelastographic parameter do you expect to be altered in this
patient?
A. Reaction (R) time
B. Kinetic (K) time
C. α angle
D. Maximum amplitude (MA)
E. Fibrinolysis (F)
3. During the neohepatic phase of a liver transplant, the surgical team notices
diffuse bleeding. Thromboelastography (TEG) reveals the following pattern.
Based on this pattern, which intervention is the most appropriate for the
patient’s coagulopathy?
Image by Katarina Ruscic.
A. Platelets
B. Fresh frozen plasma
C. Tranexamic acid
D. Cryoprecipitate
E. Packed red blood cells

4. 4. TEG is performed and reveals an increased R time and decreased MA.
These abnormalities are most suggestive of which of the following coagulation
deficits?
A. Decreased platelets
B. Decreased clotting factors
C. Decreased fibrinogen
D. Increased fibrinolysis
E. Both decreased platelets and decreased clotting factors
5. A patient is receiving blood product transfusions after undergoing aortic valve
replacement. Despite the transfusions, the surgeons still note that their field is
very “oozy.” TEG is performed, which reveals a decreased α angle. Which
blood product should be administered next?
A. Platelets
B. Fresh frozen plasma
C. Tranexamic acid
D. Cryoprecipitate
E. Packed red blood cells
6. The complication rate (vascular complications and nerve injuries) associated
with insertion of arterial lines closest to which of the following?
A. 3-18 per 10 patients
B. 3-18 per 100 patients
C. 3-18 per 1000 patients
D. 3-18 per 10 000 patients
E. 3-18 per 100 000 patients
7. Which nerve is at greatest risk of suffering an injury during arterial catheter
insertion into the brachial artery?
A. Median nerve
B. Radial nerve
C. Ulnar nerve
D. Musculocutaneous nerve
E. Axillary nerve
8. A “flush test” is performed to assess damping of an arterial line pressuremonitoring system. A system with an appropriate dynamic response will have
which of the following responses to rapid flushing?
A. One large oscillation before a return to baseline
B. One large and 1 small oscillation before a return to baseline
C. One large and 3 small oscillations before a return to baseline
D. Several large and several small oscillations before a return to baseline
E. A square wave

9. Which of the following is most likely to produce underdamping in an arterial
pressure monitoring system?
A. Excessive tubing length
B. Bubbles in the tubing system
C. Kink in the arterial catheter
D. Thrombus at the tip of the arterial catheter
10. 10. How does the systolic pressure measured in the dorsalis pedis artery differ
from that measured in the aorta?
A. 5 mm Hg lower than the aorta
B. 5 mm Hg higher than the aorta
C. 20 mm Hg higher than the aorta
D. 20 mm Hg lower than the aorta
E. The same systolic pressure as the aorta
