Med01 Participants MCQs and Ans

A patient with necrotizing pancreatitis undergoes CT guided aspiration, which results in growth of E-coli on culture. The most appropriate treatment is: 

A. Culture appropriate antibiotic therapy
B. ERCP with sphincterotomy
C. CT guided placement of drain(s)
D. Exploratory laparotomy


The answer is D. Exploratory laparotomy


The presence of secondary pancreatic infection suspected in patients whose systemic inflammatory response (fever, WBC count or organ dysfunction) fails to resolve, CT-guided aspiration of fluid from pancreatic bed for performance of Gram's stain & culture analysis is of critical importance. A positive is Gram's stain or culture or identification of gas within pancreas on CT-scan, mandate operative intervention.

Thiopentone does not cause:

A. Fall in intracranial tension 
B. Decreases oxygen consumption of brain 
C. Decreases metabolic rate of brain 
D. Decreases stage 2 of sleep

The ans. is .D.

Thiopentone decreases oxygen consumption, metabolic rate and ICT. That is why it is agent of choice for cerebral protection. On sleep it increases stage 2 and decreases stage 3, 4 and REM.

Which of the following sugars is absorbed from the small intestine by facilitated diffusion?

A. Glucose
B. Galactose
C. Fructose
D. Sucrose

The answer is C.
Facilitated diffusion is the major transport route for fructose. The duodenum and jejunum are the principal sites of carbohydrate absorption in humans. Digestion of carbohydrates is accomplished by amylase and brush border enzymes and results in a mixture of glucose, fructose, and galactose. A common sodium-dependent secondary active transporter absorbs glucose and galactose. Sucrose and lactose are disaccharides that break down into glucose and fructose, and glucose and galactose, respectively.
