Can you guys correct me on this
----------------------------------------------------------------------
8.old woman with DVT. Platelet dropped significantly after a week of tx. Drug of action?
a. activate tissue plasminogen -----action of tPA
b. Interferes with carboxylation of coag factors ----action of warfarin
c. irreversibly inactivate COX -----Aspirin
d. Potentiates the action of antithrombin iii (correct answer, action of Heparin, and this is Heparin induced Thrombocytopenia HIT)
e. selectively inhibits factor Xa (Heparin does thrombin factor 2 and factor Xa)

14.ER doctor successfully delivered a baby, womanis now having severe bleeding. Pelvic exam shows an ope cervix and heavy vaginal bleeding. Ligation of a branch of which of the following arteries is most appropriate?
a. external iliac (gives femoral and inferior epigastric artery)
b. internal iliac ( Correct answer I think, bcz Uterine artery is a branch of internal iliac artery)
c. internal pudendal (supplies the external structure, but also a branch of internal iliac)
d. median sacral (supply coccyx)
e. Obturator (gives blood supply to the leg obturator muscles)
----------------------------------------------------------------------------
16. A patient cries ad says it's a bad news, isn't it?! when a doc is about to tell him the progression of carcinoma to the terminal phase. Most appropriate response?
a. How have you been since the last time I saw you?
b. lets talk about hte positive aspect first
c. look on the bright side of things
d. tell me how you are feeling
e. there are other people who have it alot worse than you
f. Yes it is
g. you've had several years better off than many others with this disease.

32. A guy with chrons disease. You give antibiotics and prednisone, he got better in 3 weeks, in addition to resolving the infection, the most likely MOA of this pharmacotherapy is which of the following?
a. antibody binding
b. complement activity
c. mast cell degranulation
e. neutrophil function
f. T-lymphocyte function
I marked e. but it's wrong....so I'm guessing T-lymphocyte fumction F? as to decrease T and B cell couns. However, neutrophil count is increased.

10. 45 year old lady diagnosed with invasive ductal cell CA breast . she was started on tamoxifen and serum analysis showed decreased conc. of enoxifen the active metabolite of prodrug tamoxifen. Genetic analysis showed homozygous presence of CYP450 2D6*4 alleles. WHich of following best represents the likelihood that this patient sister has same alleles?
1.0% 2. 25% 3. 50% 4. 75% 5 100%
Can anyone solve for this one??? thanks!

49. Old man with 2 year history of decrased force of his urinary stream and increase frequency. BUN is 55 and Creatinine is 5. Ultrasound of Urinary tract shows bilateral hydronephrosis and dilated ureters. What is the mechanism of this patient's renal failure?
a. Decreased hydrostatic pressure in the glomerular capillary
b. decreased renal plasma flow
c. Increased hydrostatic pressure in Bowman space
d. Precipitation of protein in the renal tubules
e. Precipitation of uric acid in the renal tubules
---------------------------------------------------------------------
4. A 27 yo woman with fever, malaise, abdominal pain, vaginal discharge for 4 days. Pregnancy test is negative, Leukocyte count is up. Bilateral lower quadrant tenderness with rebound and guarding. Pelvic exam shows cervical bilateral adnexal tenderness. Most likely diagnosis?
a. appendicitis
b. bacterial vaginosis
c. Chancroid
d. Diverticulitis
e. Gonorrhea
f. Herpies genitalis
g. Trichomonias
Gonorrhea...I picked chancroid on the exam...because I thought chancroid can have those bubonic thing bilaterally....i guess the answer is gonorrhea?!

6. A study is designed to evaluate the efficacy of coenzyme Q10 in improving cardiac output in pts with CHF. 60 pts with CHF are recruited for the study. Each subject is assigned by coin toss to one of two groups (standard care or standard care plus coenzyme). Which of the following best describe this study design?
a. case-control
b. case-series
c. Crossover
d. Cross-sectional
e. Historical cohort
f. Randomized clinical-trials
I'm guessing F. is the correct answer bcz by giving q10, you're giving a treatment (intervention) to the study. And the coin toss gives the randomness.
a. Case-control: have 2 groups, one health as the control and one diseased. Trying to evaluate the risk factor. So the example will be: 60 pt with CHF drink more and smoke more. Healthy individuals smoke and drink less. Risk factors are smoking and drinking alcohols.
d. Cross-sectional: snap shot, trying to find out in a population who have CHF. You know the prevalence but not incidence.
e. I don't think it is either retrospective or prospective
----------------------------------------------------------------------
A guy completed amoxillin develop watery-brown stools in the past 24 hours. Clostridium difficile toxin is positive. Pathological finding is most likely to be present?
a. Bacterial Overgrwoth of the colonic surface
b.Flask-shaped ulcers in the colon
c. Giardia trophozoites linning the duodenal mucosa
d. Necrotizing granulomatous inflammation
e. PEsudomembranes of fibrin and inflammatory debris
They want us to pick e. But I have seen many qbank and wiki sources say a). Can someone tell me why not AAAAAAAAAAAAAAA??

A 1 week old girl screening sho a possible defectin fatty acid oxidation, physical exam shows no abnormality. Which of the following is the most appropriate next step in diagnosis?

c. measurement of serum amino acid conc.
d. measurement of serum electrolyte conc.
e. measurement of serum lactic acid conc.

I think it's a. actinic keratosis
