Flashcards in Pre-Test (Cardiothoracic, PVD, Urology, Ortho) Deck (41):
1

Most common test used for predictor of post-op pulmonary reserve

Post op FEV1 > 60%

2

Lung cancer treated w/ only chemo and radiation

Small cell

3

What is empyema

Accumulation of pus in the pleural cavity
*>6 weeks duration suggests fibrin deposition and decortication is needed*

4

SVC syndrome almost always due to

Malignancy (usually bronchogenic carcinoma)

5

Initial tx of lung abscess

Ab aimed at causative organism (will usually resolved without drainage)

6

Indications for operation in descending aortic aneurysms

End organ failure, continuation of pain, rupture or signs of impending rupture

7

Operation for diffuse esophageal spasm

Myotomy along the length of the manometric abnormality

8

First diagnostic step after severe chemical ingestion

Esophagram w/ water soluble contrast to look for rupture

9

First test in suspected Boerhaave

Contrast esophagram (Barium if suspected in chest, Gastrografin if suspected in abdomen)

10

Management of chylothorax

Chest tube and low fat diet (repair basically impossible)

11

When can CABG or PCI be used for MI

Two vessel dz or proximal LAD obstruction

12

Initial tx for thoracic outlet syndrome

Exercise program to strengthen should grilled muscles and decrease shoulder droop

13

Primary treatment of bronchial carcinoid

Resection (lobectomy or lesser resection as long as the tumor is gone)

14

What is needed after barium swallow shows achlasia

Esophageal motility test since other disorders may mimic achlasia

15

What CT disorder would you look for in a patient with AR pupil

Thoracic Aortic aneurysm

16

Exophthalmos from tricuspid regurg by?

Produces markedly enlarged venous pressure

17

First line drug in tx of neurogenic shock

Phenylephrine

18

Drug ass w/ increase in urine output in hypotensive, septic patients

Norepi (acts on alpha and beta)

19

If oliguric right after cardiac surgery, good test for reason

Pulm Art Cath --> Will determine volume status and cardiac status

20

Best test to evaluate the colon for early ischemia

Sigmoidoscopy

21

Lymphedema that manifests its self early in life but not at birth

Lypmhedema praecox

22

Most common area of ischemia after AAA repair

Sigmoid

23

Best management for atherosclerosis

Aspirin, Lipid Lowering drugs, Lifestyle (no smoking, exercise)

24

Best predictive test for perioperative ischemic cardiac events in patients undergoing non-cardiac surg

Dihyridamole-thalium imagin to find reversible perfusion defects

25

Best management for patients presenting with acute arterial insufficiency w/ neurologic compromise of LE

Immediate surgery (Embolectomy)

26

Most common peripheral artery aneurysms

Popliteal (53% are bilateral)

27

Best first test for suspected acute mesenteric ischemia

Mesenteric angiogram (will differentiate b/w embolic or non-occlusive due to low Cardiac index)

28

What veins can't be visualized by duplex US

Proximal veins (not accesible due to anatomic location)

29

Old frail person w/ bilateral iliac artery occlusion surgery

Axillofemoral bypass graft

30

Stones > what size need lithotripsy

1cm

31

Medicine to try for pt's w/ bilateral undescended testis

Chorionic gonadotropin --> if not help after one month need surgery before age 2

32

Surgery to resolve testicular torsion

Orchiopexy --> fixes testicles in place

33

Tx for RCC

Radical nephrectomy (may be cure even w/ enlarged nodes because those may be reactive)

34

Absolute indication for surgery in pt's w/ BPH

Recurrent UTIS, retention refractory to medical therapy, upper tract dilation, renal inuff 2/2 outflow obstruction, bladder stones

35

First test for suspected rupture of urethra

Retrograde urethrogram

36

Given massive amounts of muscle damage during open fractures, what are liberally performed

Fasciotomies

37

Posterior boundary of shoulder joint? Laterally by?

Posterior by teres minor and infraspinatus
Lateral by deltoid

38

Injury to the wrist at the radial nerve would cause

Mostly sensory abnormalities (more proximally would cause extensor abnormalities)

39

When is external fixation used in ortho trauma

Most often in the setting of high engr. trauma with significant soft tissue and vascular injury, or in polytrauma as "damage control"

40

What is osteitis fibrosa cystica

Ass w/ hyperparathyroidism --> inc bone turnover w/ elevated alk phos
*brown or osteoclastic tumors and bone cysts may be present on long bones*

41

Bone tumor where pain is relieved by aspirin

Small lucency on X-ray surrounded by reactive sclerosis
