Q- Which of the following is the most common cause of acute mesenteric ischemia?
A- Abdominal aortic aneurysm
B- Embolism
C- Mesenteric vein thrombosis
D- Vascular autoimmune disease
B- Embolism- The most common cause of acute mesenteric ischemia is a superior mesenteric artery embolism, often originating from the heart (e.g., atrial fibrillation). Mesenteric vein thrombosis and autoimmune vasculitis are less common causes.
Q- A patient presents to the ER with an acute myocardial infarction. After taking aspirin and oxygen, what is the next step of action?
A- Administer metoprolol
B- Check cardiac biomarkers
C- Initiate perfusion therapy
D- Send for echocardiography
C- Initiate perfusion therapy- If a patient is already diagnosed with acute myocardial infarction and has received aspirin and oxygen, the next immediate and life-saving step is to begin reperfusion therapy (PCI if available, or thrombolytics if PCI is not immediately available). Metoprolol, biomarkers, and echocardiography are important—but none take priority over restoring coronary blood flow.
Q- Varicella zoster vaccine is not recommended if an elderly patient has already developed shingles.
A- True
B- False
B- False- Even if an elderly patient has already had shingles, the varicella zoster vaccine (Shingrix) is still recommended because it significantly reduces the risk of recurrence and complications such as postherpetic neuralgia.
