1.       15. A 61-year-old Asian female presents with headache, fever and photophobia of 5 day duration.  She has never had anything like this before.  In the emergency room, she appears lethargic and uncomfortable, but mentally clear.  T101.9F, RR 18, P98, BP 104/62.  She has nuchal rigidity as well as photophobia.  Fundoscopic exam reveals no papilledema.  The rest of the physical exam is unremarkable. She has recently returned from a trip to Ohio. A Lumbar puncture is performed immediately.  Results from the fluid: WBC 100/ml (80% lymphocytes) 25 RBCs, total protein 68, glucose 80.  Gram stain shows no organisms.  Tube 4 shows the same results as tube 1.  Opening pressure is 30 cm H2O.   This is most consistent with:

       A 52 year old white male presents with increased abdominal distention over 3 weeks.  Patient has noticed a 14 lb weight gain over the last 4 months and increasing fatigue.   Patient has also noticed edema in his ankles over the same time frame.  He has history of mild hypertension. On physical exam, patient is awake alert in no acute distress. Blood pressure is 100/60.  Respiratory 12, heart rate 73, temperature is afebrile.  HEENT is significant for no scleral icterus.  Skin exam has no jaundice.  Chest was clear to auscultation.  Heart was regular rate and rhythm. Abdomen is protuberant with some shifting dullness. Patient has 3+ edema bilaterally to the mid calf. Lab values are significant for a normal CBC, normal basic chemistry, creatinine of 0.9.  Albumin is 2.7, AST 33, ALT 43, total bili 1.2, LDH 458, alkaline phosphatase 337. Patient subsequently has a paracentesis of 4 L of cloudy fluid.   Fluid lab values: Albumin 1.2, total protein 3.2.  LDH 345.  Cell count 400 with 85% histiocytes.  Cultures of the fluid were sent.   What is the most likely cause of patient’s ascites?

If you receive a 0 on an exam for not following an instruction or rule, you can’t replace that 0 with the final exam. 

A little league baseball player has a batting average of 0.470. In other words, the probability is 0.47 that the player will get a hit on his next at bat. Let X represent the number of hits out of the next 9 at bats, and suppose X follows a binomial distribution. Find the probability that he has at least 1 hit in his next 9 at bats.
