    Bile by-products ultimately leave the body through ________, and blood by-products ultimately leave the body through ________.

    • Sweat, respirations

    • Blood, urine

    • Feces, blood

    • Feces, urine

    • Respirations, sweat

    Correct Answer
    A. Feces, urine
    Explanation
    Bile is produced by the liver and stored in the gallbladder. It helps in the digestion of fats. After being used in the digestion process, bile by-products are eliminated from the body through the feces. On the other hand, blood by-products, such as waste products and excess water, are filtered by the kidneys and eliminated through the urine. Therefore, the correct answer is feces, urine.

    What substance that the liver synthesizes determines plasma oncotic pressure?

    • Coagulation factors

    • Alpha-1 antitrypsin

    • Albumin

    • Ceruloplasmin

    Correct Answer
    A. Albumin
    Explanation
    Albumin is a protein synthesized by the liver that plays a crucial role in maintaining plasma oncotic pressure. Plasma oncotic pressure is the pressure exerted by proteins, primarily albumin, in the blood vessels that helps to retain fluid within the blood vessels. Albumin helps to prevent fluid from leaking out of the blood vessels into the surrounding tissues. Therefore, albumin is the substance synthesized by the liver that determines plasma oncotic pressure.

    What causes impaired excretion of conjugated bilirubin?

    • Hematostasis

    • Bacteristatic

    • Diarrhea

    • Cholestasis

    Correct Answer
    A. Cholestasis
    Explanation
    Impaired excretion of conjugated bilirubin is caused by cholestasis. Cholestasis refers to a condition where there is a reduction or blockage in the flow of bile from the liver. This can occur due to various reasons such as liver diseases, gallstones, or obstruction of the bile ducts. When cholestasis occurs, bilirubin, which is a waste product formed from the breakdown of red blood cells, cannot be properly excreted from the body. As a result, it accumulates in the blood, leading to jaundice and other symptoms associated with liver dysfunction.

    Rate this question:

  • 7. 

    Canalicular enzymes help to diagnose biliary obstruction.  Which of the following is a canicular enzyme?

    • Albumin

    • Transferrin

    • Alkaline phosphatase

    • Alpha1-antitrypsin

    Correct Answer
    A. Alkaline phosphatase
    Explanation
    Alkaline phosphatase is a canalicular enzyme. Canalicular enzymes are enzymes that are found in the bile canaliculi, which are small ducts that transport bile from the liver to the gallbladder and small intestine. Alkaline phosphatase is one of the enzymes that is produced by the liver and is involved in the metabolism of bile. Elevated levels of alkaline phosphatase in the blood can indicate biliary obstruction, as the enzyme is released into the bloodstream when the flow of bile is blocked. Therefore, alkaline phosphatase is a useful marker for diagnosing biliary obstruction.

    Rate this question:

  • 8. 

    Is Hepatitis C a DNA/RNA virus?

    • DNA

    • RNA

    Correct Answer
    A. RNA
    Explanation
    Hepatitis C is caused by the Hepatitis C virus (HCV), which is an RNA virus. RNA viruses have RNA as their genetic material, unlike DNA viruses which have DNA. Therefore, the correct answer is RNA.

  • 9. 

    The liver synthesizes and excretes VLDL.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The liver is responsible for synthesizing and excreting VLDL, which stands for very low-density lipoprotein. VLDL is a type of lipoprotein that transports triglycerides from the liver to other tissues in the body. This statement is true because the liver plays a crucial role in lipid metabolism and is involved in the production and secretion of various lipoproteins, including VLDL.

    Which form of hepatitis is self limiting, will not incur a carrier state or chronic disease state?

    • B

    • A

    • C

    • D

    Correct Answer
    A. A
    Explanation
    Hepatitis A is a form of hepatitis that is self-limiting, meaning it resolves on its own without treatment. It does not lead to a carrier state or chronic disease state. Hepatitis A is typically transmitted through contaminated food or water, and symptoms may include fatigue, nausea, and jaundice. Vaccination is available to prevent hepatitis A infection.

    True or false. The AST/ALT ratio is less accurate if AST>10x normal.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The AST/ALT ratio is less accurate when AST levels are extremely elevated, specifically when AST is greater than 10 times the normal range. This means that in cases where AST levels are significantly higher than normal, the AST/ALT ratio may not provide an accurate indication of liver function.

    Rate this question:

  • 12. 

    What disease process creates fibrosis and conversion of normal liver tissue into structurally abnormal nodules?

    • Hepatitis

    • Hepatomegaly

    • Cirrhosis

    • Portal hypertension

    Correct Answer
    A. Cirrhosis
    Explanation
    Cirrhosis is a disease process that leads to the formation of fibrosis and the conversion of normal liver tissue into structurally abnormal nodules. It is characterized by the progressive scarring of the liver, which disrupts its normal function. This scarring is a result of chronic liver damage, commonly caused by long-term alcohol abuse, viral hepatitis, or other conditions that affect the liver. As the disease progresses, the liver becomes increasingly scarred and nodules replace healthy tissue, leading to complications such as liver failure and portal hypertension.

    Rate this question:

  • 13. 

    What substance synthesized by the liver is mainly made up of cholesterol?

    • Alpha 1-antitrypsin

    • Ceruloplasmin

    • Transferrin

    • Bile salts

    Correct Answer
    A. Bile salts
    Explanation
    Bile salts are synthesized by the liver and are mainly made up of cholesterol. Bile salts play a crucial role in the digestion and absorption of dietary fats. They help in the emulsification of fats, which increases their surface area and allows for better digestion by enzymes. Bile salts also aid in the absorption of fat-soluble vitamins. Therefore, bile salts are an important component of bile, which is produced by the liver and stored in the gallbladder before being released into the small intestine to aid in digestion.

    Rate this question:

    Enlargement can be from focal lesions, which of the following is an example of a focal lesion?

    • Lymphoma

    • Cysts

    • Infectious disease

    • Amloidosis

    • Venous congestion

    Correct Answer
    A. Cysts
    Explanation
    Cysts are an example of a focal lesion. Focal lesions refer to abnormalities or changes that are localized to a specific area or region within the body. Cysts are fluid-filled sacs that can develop in various parts of the body and are considered focal lesions because they typically occur in a specific location rather than affecting the entire body.

  • 15. 

    Unconjugated bilirubin travels to the liver via plasma, bound to what?

    • Transferrin

    • VLDL

    • Albumin

    • Ferritin

    Correct Answer
    A. Albumin
    Explanation
    Unconjugated bilirubin, which is a waste product of red blood cell breakdown, is insoluble in water and therefore needs to be transported to the liver for further processing. It binds to albumin, a protein found in the plasma, for transport. Albumin acts as a carrier molecule, allowing the unconjugated bilirubin to be transported safely to the liver where it can be conjugated and eventually eliminated from the body. Transferrin is responsible for transporting iron, VLDL carries triglycerides, and ferritin stores iron, none of which are involved in the transport of unconjugated bilirubin.

    Rate this question:

  • 16. 

    What is the maximum amount of cells the liver can have damaged or lost before failing to function?

    • 1/2

    • 1/3

    • 1 1/2

    • 3/4

    Correct Answer
    A. 3/4
    Explanation
    The maximum amount of cells the liver can have damaged or lost before failing to function is 3/4. This means that if 3/4 or more of the liver cells are damaged or lost, the liver will no longer be able to carry out its functions effectively.

    Rate this question:

  • 17. 

    High amounts of what substance makes urine a dark tea-color?

    • Conjugated bilirubin

    • Unconjugated bilirubin

    Correct Answer
    A. Conjugated bilirubin
    Explanation
    Conjugated bilirubin is the correct answer because it is a substance that can cause urine to appear dark tea-color. Bilirubin is a yellow pigment that is produced when red blood cells break down. In the liver, bilirubin is conjugated with glucuronic acid, which makes it soluble in water and allows it to be excreted in the urine. When there is a high amount of conjugated bilirubin in the urine, it can give it a dark tea-color. Unconjugated bilirubin, on the other hand, is not soluble in water and is typically excreted in the feces, so it does not contribute to the color of urine.

    Rate this question:

  • 18. 

    What is hemochromatosis?

    • Problem with white blood cell maturation

    • Iron storage disorder

    • Malformation of red blood cells

    • Inflammation of red blood cells

    Correct Answer
    A. Iron storage disorder
    Explanation
    Hemochromatosis is a condition characterized by excessive iron absorption and accumulation in the body. This leads to iron overload and can result in damage to various organs, including the liver, heart, and pancreas. It is not related to white blood cell maturation, malformation of red blood cells, or inflammation of red blood cells. Therefore, the correct answer is "iron storage disorder."

    Rate this question:

  • 19. 

    Which of the following is NOT a canalicular enzyme?

    • Alpha1-antitrypsin

    • Alkaline phophatase

    • Gamma-glutamyltransferase (GGT)

    • 5'-nucleotidase

    Correct Answer
    A. Alpha1-antitrypsin
    Explanation
    Alpha1-antitrypsin is not a canalicular enzyme because it is primarily synthesized in the liver and secreted into the bloodstream, rather than being transported into the bile canaliculi. Canalicular enzymes, on the other hand, are enzymes that are synthesized in the liver and transported into the bile canaliculi, where they play a role in the formation of bile. Examples of canalicular enzymes include alkaline phosphatase, gamma-glutamyltransferase (GGT), and 5'-nucleotidase.

    What disease process manifests with Kayser-Fleischer rings around the corneas?

    • Hepatitis

    • Charlie's syndrome

    • Cirrhosis

    • Wilson's disease

    Correct Answer
    A. Wilson's disease
    Explanation
    Wilson's disease is a genetic disorder that causes the body to retain copper, leading to its accumulation in various organs, including the liver, brain, and corneas. Kayser-Fleischer rings are a characteristic finding in Wilson's disease, which are brownish-green rings that form around the corneas due to copper deposition. This symptom is helpful in diagnosing Wilson's disease and differentiating it from other liver diseases like hepatitis or cirrhosis. Charlie's syndrome is not a recognized medical condition, making it an incorrect option.

    • Asterixis

    • Fetor hepaticus

    • Hepaticus asterixis

    • Mentos

    Correct Answer
    A. Fetor hepaticus
    Explanation
    Fetor hepaticus is a term used to describe the musty odor in the breath and urine that is commonly seen in patients with hepatic encephalopathy. This odor is caused by the accumulation of certain toxins in the body due to liver dysfunction. Asterixis, on the other hand, refers to a tremor-like movement of the hands and is not related to the odor. Hepaticus asterixis and mentos are not valid terms or concepts related to the given question.

    Which type of bilirubin can cross the blood brain barrier and cause kernicterus?

    • Unconjugated

    • Conjugated

    Correct Answer
    A. Unconjugated
    Explanation
    Unconjugated bilirubin is the correct answer because it is the form of bilirubin that can cross the blood-brain barrier and cause kernicterus. Kernicterus is a neurological condition that occurs when unconjugated bilirubin levels in the blood are too high, leading to the deposition of bilirubin in the brain. Conjugated bilirubin, on the other hand, is unable to cross the blood-brain barrier and does not cause kernicterus.

    WHat is the most common form of hyperbilirubinemia?

    • Seguards syndrome

    • Wilsons disease

    • Gilbert's Syndrome

    • Mesa's Syndrome

    Correct Answer
    A. Gilbert's Syndrome
    Explanation
    Gilbert's Syndrome is the most common form of hyperbilirubinemia. It is a benign condition characterized by elevated levels of unconjugated bilirubin in the blood. This occurs due to a deficiency in the enzyme responsible for bilirubin metabolism. The syndrome is typically asymptomatic, but individuals may experience intermittent jaundice or mild fatigue. It is important to note that Gilbert's Syndrome does not cause any serious health problems or liver damage.

    Correct Answer
    A. Bone and liver
    Explanation
    Alkaline phosphatase is mainly found in bone and liver. It is an enzyme that is involved in various important biological processes such as bone mineralization and liver function. In bone, alkaline phosphatase plays a crucial role in the formation and remodeling of bone tissue. In the liver, it is involved in the metabolism and detoxification of various substances. Therefore, the presence of alkaline phosphatase in both bone and liver makes it the correct answer.

    Rate this question:

  • 33. 

    True or false. Unconjugated bilirubin is a hydrophillic toxin.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Unconjugated bilirubin is actually a hydrophobic toxin. It is produced during the breakdown of red blood cells and is transported to the liver where it is conjugated with glucuronic acid to form conjugated bilirubin. Conjugated bilirubin is then excreted in bile and eliminated from the body. Unconjugated bilirubin is not soluble in water and needs to be bound to albumin for transport in the blood. It can only become toxic when its levels are excessively high or when it is not properly processed by the liver.

    Gilbert's syndrome is a problem with what enzyme?

    • Transaminase

    • Glucuronyl transferase

    • Glucophage

    • Amylase

    • Lipase

    Correct Answer
    A. Glucuronyl transferase
    Explanation
    Gilbert's syndrome is a genetic disorder that affects the liver's ability to process bilirubin, a waste product of red blood cell breakdown. Glucuronyl transferase is the enzyme responsible for conjugating bilirubin with glucuronic acid, making it water-soluble and allowing it to be excreted in the bile. A deficiency or dysfunction of this enzyme leads to an accumulation of unconjugated bilirubin in the blood, resulting in the characteristic symptoms of Gilbert's syndrome, such as jaundice.

    Which kind of portal hypertension is most commonly found with right-sided heart failure?

    • Presinusoidal hypertension

    • Postsinusoidal hypertension

    • Intrasinusoidal hypertension

    Correct Answer
    A. Postsinusoidal hypertension
    Explanation
    Postsinusoidal hypertension is the most commonly found kind of portal hypertension with right-sided heart failure. In right-sided heart failure, there is an increase in pressure in the right side of the heart, which leads to congestion and increased resistance in the hepatic veins. This increased resistance causes blood to back up into the portal vein, leading to postsinusoidal hypertension. This type of portal hypertension is characterized by increased pressure in the hepatic sinusoids and can result in complications such as ascites and variceal bleeding.

    A. Neuropsychiatric in nature
    Explanation
    Hepatic encephalopathy is a condition that affects the brain and is characterized by neuropsychiatric symptoms. It is not directly caused by hepatitis A or hepatitis B. Increased copper in the blood does not play a role in the development of hepatic encephalopathy. Therefore, the correct answer is that hepatic encephalopathy is neuropsychiatric in nature.

    Which of the following are causes for extrahepatic cholestasis?

    • Cirrhosis

    • Cholangitis

    • Viral hepatitis

    • Drug toxicity

    Correct Answer
    A. Cholangitis
    Explanation
    Cholangitis is inflammation of the bile ducts, which can lead to obstruction and extrahepatic cholestasis. This condition can cause a backup of bile in the liver, leading to symptoms such as jaundice and itching. Cirrhosis, viral hepatitis, and drug toxicity can also cause liver damage, but they may not directly result in extrahepatic cholestasis.

    Is hepatitis B cause by an RNA or DNA virus?

    • RNA

    • DNA

    Correct Answer
    A. DNA
    Explanation
    Hepatitis B is caused by a DNA virus. The hepatitis B virus (HBV) belongs to the Hepadnaviridae family, which is a group of enveloped DNA viruses. The virus contains a partially double-stranded DNA genome, and it replicates through reverse transcription, a process in which the viral RNA is converted into DNA. This DNA is then integrated into the host cell's genome, leading to chronic infection in some cases. Therefore, the correct answer is DNA.

    What disease process may manifest as gonadal atrophy in men and amenorrhea in women?

    • Wilson's disease

    • Cholangitis

    • Hemochromotosis

    • Cirrhosis

    Correct Answer
    A. Hemochromotosis
    Explanation
    Hemochromatosis is a disease process characterized by the excessive accumulation of iron in the body. In men, this can lead to gonadal atrophy, which is the shrinkage of the testes and decreased production of hormones. In women, it can cause amenorrhea, which is the absence of menstrual periods. Therefore, hemochromatosis can manifest as both gonadal atrophy in men and amenorrhea in women.

    What is the earliest marker for acute infection in hepatitis B?

    • ALT

    • IgG

    • HBeAg

    • HBsAg

    Correct Answer
    A. HBsAg
    Explanation
    The earliest marker for acute infection in hepatitis B is HBsAg. HBsAg stands for hepatitis B surface antigen, which is a protein on the surface of the hepatitis B virus. It can be detected in the blood before symptoms of infection appear and before other markers such as ALT (alanine aminotransferase), IgG (immunoglobulin G), or HBeAg (hepatitis B e antigen) become detectable. Therefore, HBsAg is considered the earliest and most reliable marker for acute hepatitis B infection.
