uWorld Flashcards
Classic presentation of gallstones
- Biliary colic
- nausea/vomiting
- right sided shoulder/subscapular pain (referred)
Episode caused by viscus distention
Splenic injury from blunt trauma is managed how?
By patient’s hemodynamic status and response for IV fluids.
- If responsive- CT scan
- If unresponsive- laparotomy
Solitary Pulmonary Nodule (SPN)
< 3 cm in diameter
completely surrounded by lung parenchyma
does not contact pleura, hilum, or mediastinum
Atelectasis

Most severe during 2nd post-op night, can last up to 5 days.
Hypovolemic shock
- Flat neck veins
- Bruising
- Abdominal distention
Eschar
Firm, necrotic tissue formed on exposed tissue following burn wounds.
Signs of compartment syndrome

Treatment for Slipped Capital Femoral Epiphysis (SCFE)
Surgical pinning of of slipped epiphysis in situ (where it is) to lessen risk of avascular necrosis of femoral head and chondrolysis.

complication of perforated appendix
significant abdominal pain with flexion of hip against resistance
Treat with antibiotics, IVF, bowel rest
appendectomy 6-8 weeks later
Dumping syndrome
Common postgastrectomy complication.
Caused by rapid emptying of hypertonic gastric content into duodenum and sm intestine. Leads to fluid shift from intravascular space to sm intestine, release of intestinal vasoactive polypeptide, stimulation of autonomic reflexes

most common cause of lower extremity edema
venous insufficiency (valvular incompetence)
risk factors of Peripheral Artery Disease (PAD)
- increasing age
- DM
- cigarette smoking
- HTN
- HLD
Dx: ankle-brachial index (ABI) using Doppler
Ankle-Brachial Index (ABI)
ratio of systolic blood pressure of posterior tibial and dorsalis pedis arteries over systolic of brachial artery
NL: 1-1.3
abnormal 50% occlusion
< 0.4 consistent with limb ischemia
Tx: ASA and cilostazol
Post-procedure with dull abdominal pain and bloody diarrhea
Colonic ischemia
causes: loss of collateral circulation
manipulation of vessels with instruments
prolonged aortic clamping
impaired blood flow through inferior mesentaric
increased alkaline phosphatase
normal serum calcium and phosphorous
