following a myocardial infarction: levels begin to increase 4 to 6 h after the onset of

chest pain, reach maximal serum concentration inabout 12 to 24 h, and remain elevated for about 7 to 10 days?

a. AST (SGOT) b. CPK-MB

c. LDH (with isotype LDH1 greater than LDH2) d. Troponin I

2. Which of the following scan will selectively label the infracted area if the patient has

MI?

a. Thallium-201 b. Xenon-131

c. Technetium-99 PYP d. MUGA scan

3. Probing into the etiological causes for MI, the patient was found to haveatherosclerotic changes in his coronary vessels. The patient did not have a familial

a. Streptococcus pyogenes b. Staph aureus

c. Chlamydia pneumoniae d. Streptococcus pneumoniae

e. GAS ( Group A Streptococci)

4. The presence of lipoprotein(a) elevated is also seen. The possible reason for Lp (a)

being a risk factor is related to the fact that lipoprotein(a) has kringle regions, which

are regions that have structural homology with

a. Cardiolipin, and this homology increases the formation of clots on cardiac valvesb. Plasminogen, and this homology decreases the ability to clear thrombi

c. Lipoprotein lipase, and this homology decreases the ability to metabolize chylomicrons

d. Fibrinogen, and this homology increases the formation of fibrin thrombi

5. A 36 year old male develops high fever with chill and rigor. On examination he was

found to have well defined erythematous rashes. Blood and CSF culture were done. CSF

was sterile. However it was considered to be a bad prognosis. Three days later he

significantly?a. Chest radiograph b. Stool guaiac c. Pap Smear d. Serum carcinoembryonic antigen

10. A 25 year old male had a road traffic accident and had sustained a wound in h is

right arm which he left untreated. Four days later the wound was markedly swollen.

Examination revealed crepitance. The wound margin has no neutrophils. Which was

the infective organism?

a. Candida albicans b. Clostridium perfringensc. Listeria monocytogens d. Bacteroide fragilis

11. Increasing the plasma concentration of which substance(s) will result in an increase

in the clearance?a. Inulin b. Glucose c. pAH d. All of the above

12. In which of the following metastatic calcification is more likely to be seen?

a. Tuberculosis of lung b. Acute pancreatitis c. Vit D intoxication d. Aortic Stenosis
