The Parkland formula is an estimate of the total fluid requirement in the first 24 hours for burn victims and is calculated as total fluids = […].
The Parkland formula is an estimate of the total fluid requirement in the first 24 hours for burn victims and is calculated as total fluids = 4 mL * TBSA% x body weight (kg).
50% is given in the first eight hours and 50% is given in the next 16 hours; total body surface area (TBSA) may be estimated using the imaging below

The three components of the Glasgow coma scale (GCS) are eye opening, verbal response, and motor response.
useful for predicting the prognosis of coma and other medical conditions (e.g. traumatic brain injury, bacterial meningitis, etc.)

Varicoceles increase in size with standing and Valsalva maneuvers.
What abdominal aortic aneurysm repair complication results in progressive abdominal pain and bloody diarrhea?
Bowel ischemia/infarction
due to inadequate perfusion after loss of IMA during aortic graft placement
What abdominal mass presents in newborns as a soft, moist, pink, pedunculated lesion after the umbilical cord has separated?
Umbilical granuloma
What acid-base disturbance is expected in patients with atelectasis?
Respiratory alkalosis
due to hyperventilation to compensate for hypoxemia
What acid-base disturbance typically occurs with acute mesenteric ischemia?
Metabolic acidosis (elevated lactate)
What agents (2) may be used to rapidly reverse the effects of warfarin?
fresh frozen plasma (FFP) or prothrombin complex concentrate (PCC)
What anatomical landmark separates the upper and lower GI tracts?
ligament of Treitz
thus, this is useful for separating upper GI bleeds (e.g. melena) versus lower GI bleeds (e.g. hematochezia)
What anesthetic is associated with adrenal insufficiency, especially in elderly and critically ill patients?
Etomidate
due to inhibition of 11β-hydroxylase
What anesthetic is associated with neurotoxicity in patients with vitamin B12 deficiency?
Nitrous oxide
N2O inactivates vitamin B12, resulting in inhibition of methionine synthase
What are the most common peripheral artery aneurysms?
[…] (#1) and […] (#2)
popliteal (#1) and femoral (#2)
frequently associated with abdominal aortic aneurysms
What are the most important early steps (2) for managing flail chest?
pain control and supplemental O2
What areas (2) of the colon are most commonly effected by ischemic colitis?
splenic flexure and rectosigmoid junction
watershed areas
What artery is at risk for injury with supracondylar fracture of the humerus?
Brachial artery
What bacteria is the most common cause of acute bacterial parotitis?
Staphylococcus aureus
What bacteria is the most frequent cause of nosocomial bloodstream infection in patients with intravascular devices?
Coagulase-negative staphylococci (e.g. S. epidermidis)
What bacteria is typically responsible for acute prepatellar bursitis?
Staphylococcus aureus
What blunt chest trauma complication is characterized by unilateral decreased breath sounds and patchy, irregular alveolar infiltrate on imaging < 24 hours after the injury?
Pulmonary contusion
**the infiltrate is NOT restricted by anatomical borders; other clinical features include tachypnea, tachycardia, and hypoxia, which may be worsened by intravascular volume expansion, as well as chest wall bruising
What blunt chest trauma complication presents with a triad of hypotension, distended neck veins, and distant heart sounds?
Cardiac tamponade (“Beck’s triad”)
What brain injury typically occurs from traumatic acceleration/deceleration shearing forces?
Diffuse axonal injury
patients typically have coma with head CT showing diffuse small bleeds at the gray-white junction
What breathing instrument is useful for preventing post-operative atelectasis?
Incentive spirometer
What BUN:creatinine ratio is indicative of prerenal acute kidney injury?
> 20:1
other characteristic symptoms include oliguria and unremarkable urine sediment
What cardiac catheterization complication presents with sudden hemodynamic instability and ipsilateral flank/back pain?
Retroperitoneal hematoma
typically occurs within 12 hours of catheterization; treatment is supportive
What cardiac complication is associated with succinylcholine in patients with skeletal muscle trauma?
Cardiac arrhythmia
secondary to hyperkalemia due to efflux of K+ ions following binding of succinylcholine to post-synaptic ACh receptors; also may occur in patients with burn injury and stroke
What class of analgesics may contribute to prolonged post-operative ileus?
Opiates
What class of drugs may precipitate symptoms of sphincter of Oddi dysfunction?
Opioid analgesics (e.g. morphine)
What demographic is most commonly associated with umbilical hernia?
African-American infants
What diagnosis is suggested by the CT image below?
Ruptured AAA
symptoms include hypotension and abdominal or back pain
What digestive enzyme may be elevated in patients with acute mesenteric ischemia?
Amylase
What disease often manifests in young males as a painful, fluctuant mass above the anus in the intergluteal region with associated discharge?
Pilonidal disease
due to an occluded, infected hair follicle; most frequently affects males age 15-30, obese individuals, those with sedentary lifestyles, and those with deep gluteal clefts
What does the drop arm test test for?
Rotator cuff tears (particularly the supraspinatus tendon)
What drug classes (2) are useful for the management of anal fissures?
topical anesthetics and vasodilators
e.g. lidocaine and nifedipine; initial management of anal fissures should include a high-fiber diet, stool softeners, and sitz baths
