    These are all related to ascites: Reduced production of albumin—hypoalbuminemia, reduced oncotic pressure of the plasma Portal hypertension—increased transudation of fluid into the abdomen Hyperaldosteronism—sodium and water retention in the kidneys true or false

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given statement is true. Ascites is a condition characterized by the accumulation of fluid in the abdominal cavity. The three factors mentioned in the statement are known to contribute to the development of ascites. Reduced production of albumin leads to hypoalbuminemia, which in turn reduces the oncotic pressure of the plasma. Portal hypertension, which is an increase in blood pressure within the portal vein, can cause fluid to transude into the abdomen. Hyperaldosteronism, a condition where there is excessive production of aldosterone hormone, can result in sodium and water retention in the kidneys, leading to fluid accumulation in the abdomen.

    Benign tumors of the Thyroid: Adenoma is most common follicular adenoma

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Adenoma is indeed the most common benign tumor of the thyroid. Adenomas are non-cancerous growths that develop from the cells of the thyroid gland. Among the different types of adenomas, follicular adenoma is the most common. It arises from the follicular cells of the thyroid and is usually solitary. Although benign, follicular adenomas can sometimes cause symptoms such as swelling in the neck, difficulty swallowing, or changes in voice. They are typically diagnosed through imaging tests and a biopsy may be done to confirm the diagnosis. Treatment options may include surgery to remove the adenoma or monitoring the condition if it is not causing any significant problems.

    Conjugated jaundice

    • Urine dark

    • Urine normal color

    • Urine light

    Correct Answer
    A. Urine dark
    Explanation
    The correct answer is "urine dark" because conjugated jaundice refers to a condition where there is an excess of bilirubin in the bloodstream. Bilirubin is a yellow pigment that is normally excreted in the bile and gives urine its normal yellow color. However, in conjugated jaundice, the liver is unable to properly process bilirubin, leading to its accumulation in the bloodstream and subsequent excretion in the urine. This results in the urine appearing dark or brownish in color.

    Explanation
    Mechanical (obstructive) ileus refers to a type of intestinal obstruction where there is a physical blockage in the intestine, preventing the normal flow of contents. This can be caused by various factors such as atresia or stenosis (narrowing) of the intestine, stricture (abnormal narrowing), intussusception (telescoping of one part of the intestine into another), volvulus (twisting of the intestine), hernia (protrusion of a part of the intestine through a weak area), adhesions (scar tissue that causes the intestine to stick together), or neoplasms (abnormal growths or tumors). Paralytic ileus, on the other hand, is a type of intestinal obstruction caused by a lack of muscle movement in the intestine.

    Gallstones in common bile duct Carcinoma of the head of the pancreas Carcinoma of the common bile duct Carcinoma of the gallbladder (late symptom)

    • Prehepatic jaundice

    • Hepatic jaundice

    • Posthepatic jaundice

    Correct Answer
    A. Posthepatic jaundice
    Explanation
    Posthepatic jaundice refers to the obstruction of bile flow after it has been produced by the liver. This obstruction can occur due to various reasons such as gallstones in the common bile duct, carcinoma of the head of the pancreas, carcinoma of the common bile duct, or carcinoma of the gallbladder. In this case, the correct answer is posthepatic jaundice because it encompasses all the mentioned conditions that can cause obstruction of bile flow after it leaves the liver.

    Alcoholism, vomiting, tears in mucosa, bleeding

    • Mallory-Weiss syndrome

    • Gastritis

    • Primary biliary cirrhosis

    • Gilbert's Disease

    Correct Answer
    A. Mallory-Weiss syndrome
    Explanation
    Mallory-Weiss syndrome is characterized by tears in the lining of the esophagus or stomach, often caused by excessive vomiting or retching. This can lead to symptoms such as vomiting, bleeding, and tears in the mucosa. Alcoholism is a known risk factor for Mallory-Weiss syndrome, as it can lead to frequent episodes of vomiting. Gastritis is inflammation of the stomach lining and may cause similar symptoms, but it is not specifically associated with tears in the mucosa. Primary biliary cirrhosis is a chronic liver disease that affects the bile ducts, and Gilbert's Disease is a genetic disorder that affects the liver's ability to process bilirubin. Neither of these conditions are directly related to the symptoms described.

    • Intussusception

    • Volvulus

    • Paralytic ileus

    Correct Answer
    A. Intussusception
    Explanation
    Intussusception refers to the invagination or telescoping of one segment of the intestine into another. This condition can lead to ischemia, which refers to inadequate blood supply, and ultimately necrosis, which is tissue death. Therefore, intussusception is the correct answer as it explains the process of one segment of intestine folding into another, leading to ischemia and necrosis.

    Viral hepatitis Alcoholic liver disease Drug-induced liver disease Chronic hepatitis due to various causes Cirrhosis

    • Prehepatic jaundice

    • Hepatic jaundice

    • Posthepatic jaundice

    Correct Answer
    A. Hepatic jaundice
    Explanation
    Hepatic jaundice refers to a type of jaundice that occurs due to liver dysfunction. It is caused by conditions such as viral hepatitis, alcoholic liver disease, drug-induced liver disease, chronic hepatitis due to various causes, and cirrhosis. These conditions affect the liver, leading to a buildup of bilirubin in the blood, which causes the yellowing of the skin and eyes characteristic of jaundice. Therefore, hepatic jaundice is the correct answer as it encompasses all the liver-related causes of jaundice.

    This hereditary liver disease is characterized by accumulation of AAT, cirrhosis, emphysema

    • Alpha1-antitrypsin deficiency

    • Gilbert's Disease

    • Wilson's Disease

    • Hemachromatosis

    Correct Answer
    A. Alpha1-antitrypsin deficiency
    Explanation
    Alpha1-antitrypsin deficiency is a hereditary liver disease that is characterized by the accumulation of AAT (Alpha1-antitrypsin) in the liver, leading to liver damage and cirrhosis. This condition also affects the lungs, causing emphysema. AAT is a protein that helps protect the lungs from damage by enzymes released by white blood cells. In individuals with Alpha1-antitrypsin deficiency, the liver cannot produce enough of this protein or produces a defective form, resulting in its accumulation in the liver and reduced levels in the lungs. This condition is often diagnosed in young adults and can lead to serious complications if left untreated.

    • Periodontal disease (Periodontitis)

    • Stomatitis

    Correct Answer
    A. Sialadenitis
    Explanation
    Sialadenitis is the correct answer because it matches the symptoms described in the passage. The passage mentions infectious causes of enlarged salivary glands, such as bacterial infections like Staphylococcus and Streptococcus, as well as viral infections like mumps. Sialadenitis refers to inflammation of the salivary glands, which can be caused by infections. This condition can result in pain and enlarged glands, which are mentioned as symptoms in the passage. Additionally, the passage mentions autoimmune causes of enlarged salivary glands, such as Sjögren's disease, which presents with systemic symptoms and xerostomia (dry mouth), but does not match the symptoms of fibrosis and shrinking glands mentioned later in the passage.
