B. Edema
C. Light-headedness
D. Cough
2. Which of the following causes of cardiac tamponade is an indication for
immediate surgical intervention?

B. Metastatic lung cancer
C. Free wall rupture following MI
D. Systemic lupus erythematosus
3. Which of the following conditions will mask the pulsus paradoxus commonly
seen in cardiac tamponade?
A. Positive pressure ventilation
B. Mucous plug
C. Stridor
D. Chronic obstructive pulmonary disease (COPD)
4. A 67-year-old man presents with progressive dyspnea on exertion and
intermittent positional chest discomfort. His past medical history is significant
for coronary artery disease for which he underwent a 3-vessel CABG 2 years
ago. Coronary catheterization shows patent grafts. Transthoracic
echocardiography demonstrates evidence of increased ventricular
interdependence and dissociation of intrathoracic-intracardiac pressures.
Which of the following is the most likely cause of this patient’s constrictive
pericarditis (CP)?
A. Tuberculosis
B. Rheumatologic
C. Postradiation
D. Postcardiac surgical
5. The presence of which of the following findings is more consistent with a
diagnosis of restrictive cardiomyopathy (RCM) as compared with CP?
A. Expiratory flow reversal in the hepatic vein
B. Respirophasic septal shift
C. Moderate pulmonary hypertension
D. Elevated medial mitral annulus velocity (e,) ≥ 8 cm/s
6. 36. Which of the following statements is true of perioperative venous
thromboembolism (VTE) prophylaxis?
A. Novel oral anticoagulants are more effective than once-daily enoxaparin in VTE
prophylaxis without increased rates of postoperative bleeding.
B. Major trauma increases VTE risk to a greater degree than postpartum status.
C. The VTE prophylactic effects of aspirin and warfarin are synergistic.
D. Neuraxial anesthesia initiated before surgical incision reduces rates of
perioperative VTE.
7. A 48-year-old man presents for retroperitoneal sarcoma resection.
Pharmacologic VTE prophylaxis should be continued postoperatively for what
length of time?
A. 3 days
B. 14 days
C. 28 days
D. 60 days
8. Which of the following pathophysiologic changes occurs with a pulmonary
embolism?
A. Increased dead space
B. Increased shunt
C. Reduced pulmonary vascular resistance
D. Reflex bronchodilation
9. Which of the following arterial blood gas results, on an FiO2 of 0.4, is most
consistent with a diagnosis of acute, submassive pulmonary embolism?
pH PaCO2 PaO2
[HCO3
–
]
A. 7.39 44 90 26
B. 7.47 40 74 28
C. 7.59 28 90 26
D. 7.50 32 74 24
40. Which of the following ECG findings is most sensitive for acute pulmonary
embolus?
A. Incomplete right bundle branch block
B. Rightward axis
C. Sinus tachycardia
D. Large S wave in lead I, combined with Q wave and inverted T wave in lead III
