Serum amylase 1450 U/L
Ultrasonography of the gallbladder shows no abnormalities. A CT scan of the abdomen is shown (go to imgur*dot*com/TO83aZy). Which of the following is the most appropriate next step in diagnosis?

6. A 20-year-old woman comes for a routine health maintenance examination. Her temperature is 37°C (98.6°F), pulse is 80/min, respirations are 12/min, and blood pressure is 110/70 mm Hg. The S2 is split and fixed. A grade 2/6 systolic murmur is heard at the third intercostal space. Examination shows no other abnormalities. Which of the following is the most likely diagnosis?
A) Aortic insufficiency
B) Atrial septal defect
C) Mitral insufficiency
D) Patent ductus arteriosus
E) Pulmonic insufficiency
F) Tetralogy of Fallot
G) Tricuspid insufficiency
H) Ventricular septal defect (WRONG)
7. A 72-year-old woman is brought to the emergency department by her daughter because of a 3-day history of progressive confusion and lethargy. She underwent bilateral hip replacement 6 years ago. She takes no medications except for aspirin as needed for osteoarthritis. She is unable to answer questions. Her temperature is 36.2°C (97.2°F), pulse is 110/min and regular, respirations are 20/min, and blood pressure is 110/70 mm Hg. Examination shows a supple neck. The lungs are clear to auscultation. Cardiac examination shows no murmurs or gallops. The abdomen is soft with no guarding; bowel sounds are present but hypoactive. Deep tendon reflexes are 1+ bilaterally. Babinski sign is absent. Serum studies show:
Na+ 135 mEq/L
Cl− 100 mEq/L
K+ 4.2 mEq/L

8. A 72*-year-*old nursing home resident is brought to the emergency department because of abdominal pain and bloody stools for 3 days. She has dementia, Alzheimer type, and a long*standing history of constipation treated with psyllium and docusate. She is in no apparent distress. Her temperature is 39°C (102.2°F), pulse is 88/min, respirations are 18/min, and blood pressure is 150/80 mm Hg. Abdominal examination shows left lower quadrant tenderness and distention. Rectal examination shows blood and no masses. She is not oriented to place or time. Which of the following is the most likely diagnosis?
B) Celiac disease
C) Clostridium difficile colitis
D) Colon cancer
G) Irritable bowel syndrome
H) Ischemic colitis
K) Ulcerative colitis
Epigastric pain/tenderness + conjugated hyperbilirubinemia + markedly elevated amylase and ALP = gallstone pancreatitis (gallstone blocking common bile duct)
This one is tricky. So all we have is 2 episodes of pneumococcal pneumonia in an elderly patient with markedly elevated white count (predominantly lymphocytes). Looks like leukemia or lymphoma, can't make out which type with the info.
Taenia cruris is frequently present with taenia pedis. Looks like this taenia pedis was not diagnosied initially leading to recurrence.
Always rule out thyroid cancer in an elderly euthyroid patient with a solitary thyroid nodule.
She has recurrent episodes of acute pancreatitis with mass lesion on CT = pancreatic cancer. ERCP for decompression.
Fixed split S2 = ASD (the murmur described is a systolic flow murmur across pulmonary valve due to left to right shunting)
Elderly + altered mental status + markedly elevated glucose + normal anion gap (135-100+22 = 13) = nonketotic coma. Looks like she has renal damage from diabetes as well.
Classic case for DKA is a child or adoloscent with elevated glucose + metabolic acidosis with elevated anion gap due to ketoacids + abdominal pain +/- altered mental status
Elderly + acute onset abdominal pain with LLQ tenderness + fever + past Hx of constipation = acute diverticulitis
