B- Colectomy is curative

C- Continuous disease beginning at the rectum and extending without skipped areas

Q- Which of the following is the main site of action of HMG-CoA reductase inhibitors?

A- Blood

B- Liver

C- Kidney

B- Liver- HMG-CoA reductase inhibitors (statins) act primarily in the liver, where they reduce cholesterol synthesis and upregulate LDL receptors to lower blood LDL levels.



Q- Which of the following management plans is recommended for a case of myocardial infarction with 70% main left stenosis?

A- Coronary artery bypass graft (CABG)

B- Percutaneous coronary intervention (PCI)

C- Percutaneous transluminal coronary angiography (PTCA)

D- Pharmacotherapy and observation

A- Coronary artery bypass graft- A left main coronary artery stenosis of 70% is a high-risk, life-threatening lesion. The recommended management is urgent CABG, which provides better survival compared to PCI for significant left main disease. Pharmacologic therapy alone and PCI/PTCA are inadequate for a lesion of this severity.
