Which organism is the leading cause of acute pyelonephritis?
-
Proteus
-
Streptococcus
-
E. coli
-
Klebsiella
Correct Answer
A. E. coliExplanation
E. coli is the leading cause of acute pyelonephritis. This is because E. coli is a common bacterium found in the intestines and is responsible for most urinary tract infections. It can travel from the urethra to the bladder and then up to the kidneys, causing inflammation and infection in the kidneys. E. coli is particularly adept at adhering to the urinary tract and has virulence factors that allow it to cause infection. Hence, it is the most common organism associated with acute pyelonephritis.Rate this question:

An episode of sever liver necrosis as may be seen in viral hepatitis could lead to:
-
Laennec's cirrhosis
-
Alcoholic cirrhosis
-
Postnecrotic cirrhosis
-
Portal cirrhosis
Correct Answer
A. Postnecrotic cirrhosisExplanation
An episode of severe liver necrosis, such as that seen in viral hepatitis, can lead to postnecrotic cirrhosis. This type of cirrhosis occurs as a result of extensive liver cell death followed by regeneration. The necrotic liver tissue is replaced with fibrous scar tissue, which disrupts the normal structure and function of the liver. Postnecrotic cirrhosis can lead to liver failure and other complications.Rate this question:

The failure of an organ to achieve its full adult size because of incomplete development is:
-
Hypoplasia
-
Hyperplasia
-
Agenesis
-
Dysplasia
Correct Answer
A. HypoplasiaExplanation
Hypoplasia refers to the failure of an organ to achieve its full adult size due to incomplete development. This can occur due to various factors such as genetic abnormalities, inadequate blood supply, or damage during embryonic development. Unlike hyperplasia, which involves an increase in the number of cells, hypoplasia is characterized by a decrease in the size and number of cells. Agenesis refers to the complete absence or failure of an organ to develop, while dysplasia refers to abnormal cell growth and organization. Therefore, hypoplasia is the most appropriate term to describe the given scenario.Rate this question:

Choledocholithiasis is a presence of calculi in the:
-
Gallbladder
-
Common bile duct
-
Kidney
-
Ureter
-
Hepatic duct
Correct Answer
A. Common bile ductExplanation
Choledocholithiasis refers to the presence of calculi or stones in the common bile duct. The common bile duct is a tube that carries bile from the liver and gallbladder to the small intestine. When stones form in the gallbladder, they can sometimes migrate into the common bile duct, causing a blockage. This can lead to symptoms such as abdominal pain, jaundice, and digestive issues. Treatment for choledocholithiasis often involves removing the stones from the common bile duct to relieve the blockage and prevent further complications.Rate this question:

Zollinger-Ellison Syndrome
-
Alport's Syndrome
-
Goodpasture's syndrome
-
Waterhouse Fredrickson syndrome
-
Sjorgen's Syndrome
Correct Answer
A. Zollinger-Ellison SyndromeExplanation
Zollinger-Ellison Syndrome is the correct answer because it is a rare condition characterized by the presence of islet cell tumors in the pancreas. These tumors produce excessive amounts of gastrin, a hormone that stimulates the production of gastric acid. The increased acid secretion leads to recurring intractable peptic ulceration, which primarily affects the jejunum but can also occur in the duodenum or stomach. This syndrome is often associated with multiple endocrine neoplasia type 1 (MEN1) and can cause symptoms such as abdominal pain, diarrhea, and gastrointestinal bleeding.Rate this question:

Bleeding, perforation & obstruction are common complications of:
-
Peptic Ulcers
-
Acute Gastric ulcers
-
Malignant gastric ulcers
-
Acute duodenal ulcers
Correct Answer
A. Peptic UlcersExplanation
Peptic ulcers can lead to bleeding, perforation, and obstruction. Peptic ulcers are open sores that develop on the lining of the stomach, small intestine, or esophagus. When the ulcer erodes a blood vessel, it can cause bleeding. If the ulcer penetrates through the wall of the stomach or intestine, it can cause perforation, which is a hole in the organ. Obstruction can occur when the ulcer causes swelling and inflammation, blocking the passage of food through the digestive system. Therefore, bleeding, perforation, and obstruction are common complications of peptic ulcers.Rate this question:

Rectosigmoid colon
-
Ascending colon
-
Transverse colon
-
Descending colon
Correct Answer
A. Rectosigmoid colonExplanation
The rectosigmoid colon is the most common site for a primary carcinoma of the GI tract. This is because the rectosigmoid colon is the area where the sigmoid colon (the S-shaped part of the colon) transitions into the rectum. It is a common site for tumors to develop due to the prolonged exposure of the colon to fecal material, which can lead to the development of cancerous cells. Additionally, the rectosigmoid colon is also subject to increased pressure during bowel movements, which can contribute to the development of tumors.Rate this question:

Pinpoint hemorrhage due to leakage from capillary or venule are:
-
Petechiae
-
Purpura
-
Stigma
-
Bruise
Correct Answer
A. PetechiaeExplanation
Petechiae are pinpoint hemorrhages that occur due to the leakage of blood from capillaries or venules. They appear as small, flat, red or purple spots on the skin or mucous membranes. Petechiae can be caused by various factors such as trauma, infections, certain medical conditions, or medications that affect blood clotting. They are different from purpura, which are larger areas of bleeding, and bruises, which result from damage to deeper tissues. Stigma is not related to hemorrhage and therefore not the correct answer.Rate this question:

-
Excrescence
-
Ball thrombus
-
Saddle
-
Vegetation
Correct Answer
A. VegetationExplanation
Valvular thrombus refers to a blood clot that forms on the valves of the heart. The term "vegetation" is often used to describe this condition. This is because the clot appears as a mass of fibrin, platelets, and other cellular debris, resembling a vegetative growth. The term "excrescence" refers to an abnormal growth or projection, but it is not specifically associated with valvular thrombus. "Ball thrombus" and "saddle" do not accurately describe valvular thrombus.Rate this question:

Commonest cause of secondary hyperparathyroidism?
-
Adenoma
-
Adenocarcinoma
-
Chronic renal failure
-
Bone marrow carcinoma
Correct Answer
A. Chronic renal failureExplanation
Chronic renal failure is the commonest cause of secondary hyperparathyroidism. In this condition, the kidneys are unable to adequately filter and eliminate waste products from the body, leading to an imbalance of minerals and hormones, including parathyroid hormone. As a result, the parathyroid glands become overactive and produce excessive amounts of parathyroid hormone, causing secondary hyperparathyroidism. This condition is characterized by elevated levels of parathyroid hormone, low levels of calcium, and high levels of phosphorus in the blood. Adenoma, adenocarcinoma, and bone marrow carcinoma are not commonly associated with secondary hyperparathyroidism.Rate this question:

Edema of the dependant portions is likely to occur with:
-
Mitral stenosis
-
Aortic insufficiency
-
Right heart failure
-
Pericarditis
Correct Answer
A. Right heart failureExplanation
Edema of the dependent portions refers to the accumulation of fluid in the lower parts of the body, such as the legs and ankles. Right heart failure is characterized by the inability of the right side of the heart to effectively pump blood, leading to fluid backup in the body's venous system. This increased pressure causes fluid to leak into the surrounding tissues, resulting in edema. Therefore, right heart failure is likely to cause edema of the dependent portions.Rate this question:

Which disease may lead to hepatic cirrhosis that is also associated with a defect in copper metabolism?
-
Wilson's disease
-
Hemosiderosis
-
Gauchers
Correct Answer
A. Wilson's diseaseExplanation
Wilson's disease is a genetic disorder that leads to excessive accumulation of copper in the body, primarily affecting the liver. Over time, this can cause hepatic cirrhosis, a condition characterized by scarring and damage to the liver. The defect in copper metabolism in Wilson's disease is due to a mutation in the ATP7B gene, which impairs the liver's ability to excrete excess copper into bile. As a result, copper builds up in the liver and other organs, leading to various symptoms and complications.Rate this question:

Which of the following is a small lesion of the pituitary that may be associated with Cushing's syndrome?
-
Adenocarcinoma
-
Oat cell ca
-
Chromophobe adenoma
-
Basophilic adenoma
-
Acidophilic adenoma
Correct Answer
A. Basophilic adenomaExplanation
A small lesion of the pituitary that may be associated with Cushing's syndrome is a basophilic adenoma. Basophilic adenomas are tumors of the pituitary gland that produce excess adrenocorticotropic hormone (ACTH), leading to increased cortisol production by the adrenal glands. This excessive cortisol production can result in Cushing's syndrome, which is characterized by weight gain, high blood pressure, diabetes, and other symptoms. Adenocarcinoma, oat cell ca, and chromophobe adenoma are not typically associated with Cushing's syndrome.Rate this question:

Which of the following lesions of the thyroid is most likely to spread to lymph nodes?
-
Riedel's struma
-
Papillary carcinoma
-
Follicular adenoma
-
Embryonal adenoma
-
Medullary carcinoma
Correct Answer
A. Papillary carcinomaExplanation
Papillary carcinoma is the most likely lesion of the thyroid to spread to lymph nodes. This is because papillary carcinoma is a type of thyroid cancer that commonly metastasizes to regional lymph nodes. The cancer cells can invade and spread to the nearby lymph nodes, leading to the potential for further spread throughout the body. Unlike other lesions mentioned, such as Riedel's struma, follicular adenoma, embryonal adenoma, and medullary carcinoma, papillary carcinoma has a higher propensity for lymph node involvement.Rate this question:

The valve most commonly affected by rheumatic heart disease, which usually manifests itself later in life is the?
-
Aortic
-
Tricuspid
-
Mitral
-
Ileocecal
-
Pulmonary
Correct Answer
A. MitralExplanation
Rheumatic heart disease is a condition that occurs as a result of untreated or inadequately treated strep throat or scarlet fever. It causes inflammation and damage to the heart valves. The mitral valve is the valve most commonly affected by rheumatic heart disease. This is because the left side of the heart, where the mitral valve is located, is under more pressure and strain compared to the right side. Additionally, the mitral valve is more susceptible to damage due to its structure and function. Therefore, it is not surprising that rheumatic heart disease usually manifests itself later in life with symptoms related to the mitral valve dysfunction.Rate this question:

Alternative regions of platelets and fibrin with red and white cells in a thrombus as seen macroscopically are?
-
Lines of Zahn
-
Striae
-
Lines of Conn
-
Propagating thrombus
-
Agonal thrombus
Correct Answer
A. Lines of ZahnExplanation
Lines of Zahn are seen macroscopically in a thrombus and are characterized by alternating layers of platelets and fibrin with red and white blood cells. These layers are formed during the formation of a thrombus when blood flow is disrupted and platelets start to aggregate. The layers of platelets and fibrin are formed in a laminar pattern, giving the appearance of lines. This distinct pattern helps differentiate a thrombus from a postmortem clot, where the layers are not present. Therefore, the presence of lines of Zahn is indicative of a thrombus rather than other options such as striae, lines of Conn, propagating thrombus, or agonal thrombus.Rate this question:

-
Aldosterone
-
Vitamin c
-
Magnesium
-
LDH
-
Spironolactone
Correct Answer
A. AldosteroneExplanation
Functional adenomas of the outer adrenal cortex are tumors that develop in the adrenal glands and can lead to excessive production of hormones. In this case, the correct answer is aldosterone. Aldosterone is a hormone produced by the adrenal glands that helps regulate blood pressure and electrolyte balance. Increased production of aldosterone can cause fluid retention, high blood pressure, and imbalances in sodium and potassium levels. Therefore, functional adenomas of the outer adrenal cortex can directly lead to increased production of aldosterone.Rate this question:

What is responsible for almost 90% of osmotic pressure at the capillary level mainly due to its small molecules and high concentration?
-
Gamma globulins
-
Beta globulins
-
Lipids
-
Albumin
-
Electrolytes
Correct Answer
A. AlbuminExplanation
Albumin is responsible for almost 90% of osmotic pressure at the capillary level mainly due to its small molecules and high concentration. Osmotic pressure is the force that helps to maintain the balance of fluids between the blood vessels and the surrounding tissues. Albumin, a protein found in the blood, has small molecules that can easily pass through capillary walls and its high concentration creates a strong osmotic force that draws fluid back into the blood vessels, preventing excessive fluid loss from the tissues.Rate this question:

The commonest site of origin for pulmonary embolus is the?
-
Prostatic veins
-
Heart
-
Portal vein
-
Leg vein
Correct Answer
A. Leg veinExplanation
The correct answer is leg vein. Pulmonary embolus refers to a blood clot that travels to the lungs and blocks the blood flow. It commonly originates from deep vein thrombosis (DVT) in the leg veins. DVT occurs when a blood clot forms in the deep veins of the leg, usually due to prolonged immobility, surgery, or certain medical conditions. If the clot breaks off and travels to the lungs, it can cause a pulmonary embolism. Therefore, the leg veins are the most common site of origin for pulmonary embolus.Rate this question:

A. GranulomaExplanation
A granuloma is a collection of epithelioid cells, which are macrophages that have transformed into a specific cell type resembling epithelial cells. Granulomas are typically formed in response to chronic inflammation or certain infections, such as tuberculosis or sarcoidosis. They are characterized by a central core of immune cells surrounded by a rim of fibrotic tissue. Epithelioma refers to a tumor arising from epithelial cells, while epidermoid carcinoma specifically refers to a type of skin cancer. Therefore, the correct answer is granuloma.Rate this question:
