Question 1

What is an endoscopic retrograde cholangiopancreatography's (ERCP) most common complication?

Accepted Answer

Pancreatitis

Answer

Post-ERCP pancreatitis is the most common and often the most serious complication of endoscopic retrograde cholangiopancreatography. It occurs due to irritation or injury to the pancreatic duct during the procedure, leading to inflammation of the pancreas. While other complications like cholangitis, aspiration, and perforation can occur, pancreatitis is statistically the most frequent.

Question 2

How does donepezil function when used to treat Alzheimer's disease?

Accepted Answer

Acetylcholinesterase inhibitor

Answer

Donepezil is an acetylcholinesterase inhibitor. It works by preventing the breakdown of acetylcholine, a neurotransmitter crucial for memory and learning, in the brain. By increasing the availability of acetylcholine, donepezil helps to improve cholinergic function and alleviate some cognitive symptoms associated with Alzheimer's disease.

Question 3

On his fingertips, a 26-year-old male has 3 to 4 cm depigmented irregular patches that have been there for the past two months and appear to be becoming bigger. What is probably taking place with this patient?

Accepted Answer

Loss of skin melanocytes with unclear cause

Answer

The description of 3-4 cm depigmented, irregular, and growing patches on the fingertips is characteristic of vitiligo. Vitiligo is an autoimmune condition where the body's immune system attacks and destroys melanocytes, the cells responsible for producing skin pigment. This leads to the appearance of white patches on the skin, and its cause is often unclear but involves autoimmune mechanisms.

Question 4

A 47-year-old man has been pushing his lawn mower for the past three weeks while experiencing chest pain. He states he has never been treated for similar symptoms and has no problems presently. He smoked one pack each day for twenty years until giving it up seven years ago. Physical examination results are typical. Electrocardiograms don't reveal any anomalies. Which of the following first diagnostic tests is most appropriate?

Accepted Answer

Exercise stress test

Answer

The patient's exertional chest pain, occurring while pushing a lawn mower, is highly suggestive of stable angina, even with a normal resting EKG. An exercise stress test is the most appropriate initial diagnostic test to evaluate for exercise-induced myocardial ischemia. It helps determine if the heart receives enough blood flow during physical activity, which might not be evident at rest.

Question 5

A 35-year-old woman has had a rash on her legs for the previous three weeks. No known infectious contacts exist. Her bladder infection was treated with trimethoprim-sulfamethoxazole a month ago. A generalized rash is visible on the shins, left medial ankle, and right medial calf during physical examination. Tender, diffuse, and returning to the same spots, the rash is. A couple of the lesions show bruise-like characteristics. Which of the subsequent diagnoses is most likely?

Accepted Answer

Erythema nodosum

Answer

The combination of red, tender nodules on the anterior lower legs (erythema nodosum), bilateral hilar adenopathy on chest X-ray, iritis, and systemic symptoms like malaise, dyspnea, and low-grade fever is highly characteristic of sarcoidosis. Erythema nodosum is a common cutaneous manifestation of sarcoidosis, a multisystem granulomatous disease.
