Which of the following findings suggest Cholestasis?
- A.
Increase of aminotransferases activity in serum, AST.ALT
- B.
Increase of aminotransferases activity in serum, ALT >AST
- C.
Increase of ALP and GGT activity, high cbilirubin in serum
- D.
Increase of ALP and decrease GGT activity, low cBillirubin in serum
- E.
Increase of ALT and ALP activity in serum, ALP >ALT, normal billirubin
Correct Answer
C. Increase of ALP and GGT activity, high cbilirubin in serumExplanation
The presence of an increase in ALP and GGT activity, along with high bilirubin levels in the serum, suggests cholestasis. Cholestasis refers to a condition where there is a reduction or blockage in the flow of bile from the liver, leading to the accumulation of bile salts and bilirubin in the bloodstream. ALP and GGT are enzymes that are commonly elevated in cholestasis, indicating liver dysfunction. Additionally, high bilirubin levels further support the diagnosis of cholestasis as bilirubin is a component of bile and its elevation suggests impaired bile flow.Rate this question:

Which of the following results suggest complete respiratory failure?
- A.
( high PO2, ^^ PCO2 )
- B.
(low PO2, Normal PCO2)
- C.
(Low PO2, ^^ PCO2)
- D.
(High PO2, ^^PCO2)
- E.
(High PO2, low PCO2)
Correct Answer
C. (Low PO2, ^^ PCO2)Explanation
The answer (Low PO2, ^^ PCO2) suggests complete respiratory failure because it indicates a low partial pressure of oxygen (PO2) and an elevated partial pressure of carbon dioxide (PCO2). In respiratory failure, the lungs are unable to effectively oxygenate the blood and remove carbon dioxide, leading to low levels of oxygen and high levels of carbon dioxide in the bloodstream. This can result from conditions such as severe asthma, chronic obstructive pulmonary disease (COPD), or acute respiratory distress syndrome (ARDS).Rate this question:

Which of the following laboratory findings suggest diabetes:
- A.
Fasting plasma glucose (FPG) < 140 mg/dl. measured 1
- B.
Fasting plasma glucose (FGP) > 100 mg/dl. measured 2 times
- C.
Fasting plasma glucose (FGP) <126 mg/dl. measured 2 times
- D.
Fasting plasma glucose (FGP) > 126 mg/dl. measured 2 times
- E.
Fasting plasma glucose (FGP) < 200 mg/dl. measured 1 time
Correct Answer
D. Fasting plasma glucose (FGP) > 126 mg/dl. measured 2 timesExplanation
A fasting plasma glucose (FPG) level greater than 126 mg/dl measured on two separate occasions is indicative of diabetes. This is because a fasting glucose level above this threshold indicates impaired insulin production or utilization, which is a defining characteristic of diabetes. Therefore, this laboratory finding suggests the presence of diabetes.Rate this question:

Which of the following lab findings exclude iron deficiency anemia?
- A.
Low serum iron
- B.
Low serum ferritin
- C.
Low TIBC
- D.
High TIBC
- E.
Normal serum ferritin
Correct Answer
C. Low TIBCExplanation
Low TIBC (Total Iron Binding Capacity) is a lab finding that excludes iron deficiency anemia. TIBC measures the amount of transferrin, a protein that carries iron in the blood. In iron deficiency anemia, the body tries to increase its iron absorption, leading to an increase in TIBC. Therefore, a low TIBC suggests that the body is not trying to increase iron absorption and is not indicative of iron deficiency anemia.Rate this question:

High homocysteine level
- B.
Low uric acid concentration
- C.
Low eGFR
- D.
High urea concentration
- E.
High billirubin level
Correct Answer
A. High homocysteine levelExplanation
High homocysteine level is a cardiovascular risk factor because elevated levels of homocysteine in the blood have been associated with an increased risk of developing cardiovascular diseases such as heart attack, stroke, and peripheral vascular disease. Homocysteine is an amino acid that is normally broken down and cleared from the body, but when its levels are high, it can cause damage to the lining of blood vessels, promote blood clot formation, and contribute to the development of atherosclerosis. Therefore, monitoring and managing homocysteine levels is important in assessing and reducing cardiovascular risk.Rate this question:

- D.
Low activity of CK and CK-MB
- E.
High activity of LDH and ALP
Correct Answer
C. High activity of lipase and amylaseExplanation
High activity of lipase and amylase suggests acute pancreatitis. Lipase and amylase are enzymes that are normally found in the pancreas. When the pancreas is inflamed or damaged, such as in acute pancreatitis, these enzymes are released into the bloodstream in higher than normal amounts. Therefore, measuring the activity of lipase and amylase can help in diagnosing acute pancreatitis. The other options listed do not specifically indicate acute pancreatitis.Rate this question:

Ketunuria without glycosuria is associated with:
- A.
GDM
- B.
Diabetes mellitus
- C.
Obesity
- D.
Pure carbohydrate diet
- E.
Rich carbohydrate diet
Correct Answer
B. Diabetes mellitusExplanation
Ketunuria without glycosuria is associated with diabetes mellitus. This is because ketunuria refers to the presence of ketones in the urine, which is a sign of the body breaking down fat for energy instead of glucose. In diabetes mellitus, the body is unable to properly regulate blood sugar levels, leading to high levels of glucose in the blood. When glucose is not available for energy, the body starts breaking down fat, resulting in the production of ketones. Therefore, the presence of ketunuria without glycosuria suggests that the individual may have diabetes mellitus.Rate this question:

- D.
Increased pH, decreased PCO2
- E.
Normal pH, decreased HCO3-
Correct Answer
A. Decrease pH, decrease HCO3-Explanation
A primary metabolic acidosis is characterized by a decrease in pH and a decrease in HCO3-. This means that the acidity level in the body is increased and there is a decrease in the concentration of bicarbonate ions, which help to regulate the pH. This can occur due to conditions such as diabetic ketoacidosis, renal failure, or severe diarrhea. The other options do not correspond to a primary metabolic acidosis as they either involve respiratory changes (increased or decreased PCO2) or do not involve a decrease in HCO3-.Rate this question:

- D.
Low bilirubin, LDH, haptoglobin
- E.
High bilirubin, LDH, haptoglobin
Correct Answer
A. High bilirubin, LDH, low haptoglobinExplanation
High bilirubin, LDH, and low haptoglobin levels confirm hemolysis. Bilirubin is a breakdown product of red blood cells and is typically elevated in hemolysis. LDH is an enzyme found in red blood cells, and its elevation indicates cell damage. Haptoglobin is a protein that binds to free hemoglobin released from damaged red blood cells, so low levels suggest hemolysis. Therefore, the combination of high bilirubin, LDH, and low haptoglobin is indicative of hemolysis.Rate this question:

- C.
Hemoglobinuria, negative nitrate and proteins
- D.
High urobilinogen, high bilirubin
- E.
High glucose and ketones, low proteins
Correct Answer
E. High glucose and ketones, low proteinsExplanation
The presence of high glucose and ketones in the urine, along with low proteins, suggests the possibility of uncontrolled diabetes. In diabetes, the body is unable to properly regulate blood sugar levels, leading to high glucose levels in the urine. Ketones are produced when the body breaks down fat for energy instead of using glucose. The low protein levels may indicate kidney damage, which can occur as a complication of diabetes. Overall, these findings are consistent with the diagnosis of uncontrolled diabetes.Rate this question:

- F.
Immature neutrophils
Correct Answer
B. Immature erythrocytesExplanation
Reticulocytes are immature erythrocytes, or red blood cells. They are produced in the bone marrow and then released into the bloodstream. Reticulocytes contain remnants of ribosomal RNA, which gives them a reticular or "net-like" appearance when stained. As they mature, these remnants are removed and the reticulocytes become fully functional red blood cells, responsible for carrying oxygen throughout the body. The presence of reticulocytes in the blood can indicate increased red blood cell production, such as during anemia or in response to certain medications or conditions.Rate this question:

- A.
Cholestasis
- B.
Pancreatic cancer
- C.
Hemolytic anemia
- D.
The pancreases of gallstones
- E.
Biliary tract obstacles
Correct Answer
C. Hemolytic anemiaExplanation
The correct answer is hemolytic anemia. Hemolytic anemia is a condition characterized by the breakdown of red blood cells, leading to the release of urobilinogen into the bloodstream. This excess urobilinogen is then filtered by the kidneys and excreted in the urine, resulting in a high urobilinogen urine level. Cholestasis, pancreatic cancer, gallstones in the pancreas, and biliary tract obstacles do not directly cause the breakdown of red blood cells, therefore they would not be expected to result in a high urobilinogen urine level.Rate this question:

125-185 mg/dl
- B.
100-125 mg/dl
- C.
70-100 mg/dl
- D.
> 200 mg/dl
Correct Answer
C. 70-100 mg/dlExplanation
The normal range for fasting glucose is 70-100 mg/dl. Fasting glucose refers to the blood sugar level after not eating or drinking anything except water for at least 8 hours. This range is considered normal because it indicates that the body is able to maintain stable blood sugar levels without any signs of diabetes or other metabolic disorders. Glucose levels below 70 mg/dl may indicate hypoglycemia, while levels above 100 mg/dl may suggest prediabetes or diabetes.Rate this question:

A decrease in neutrophils in the peripheral blood can be referred to as:
- A.
Neutropenia
- B.
A shift to the left
- C.
Agranulocytosis
- D.
Netrophilia
Correct Answer
A. NeutropeniaExplanation
Neutropenia refers to a decrease in the number of neutrophils in the peripheral blood. Neutrophils are a type of white blood cell that play a crucial role in fighting off infections. When there is a decrease in neutrophils, the body becomes more susceptible to infections. A shift to the left, on the other hand, refers to an increase in the number of immature neutrophils, indicating an inflammatory response. Agranulocytosis is a severe form of neutropenia where there is a near-complete absence of neutrophils. Neutrophilia, on the other hand, refers to an increase in the number of neutrophils, which can be a sign of infection or inflammation.Rate this question:

Which laboratory test is the most important for patients with anuria?
- A.
Urea level in serum
- B.
Sodium ion in urine
- C.
Kalium iron in serum
- D.
Creatinine in serum
Correct Answer
C. Kalium iron in serumExplanation
The correct answer is creatinine in serum. Anuria refers to the absence of urine production, which can be caused by various factors including kidney dysfunction. Creatinine is a waste product that is filtered out of the blood by the kidneys and excreted in urine. Therefore, measuring creatinine levels in the blood can provide important information about kidney function. High levels of creatinine in the serum indicate impaired kidney function, which is crucial to assess in patients with anuria. Urea level in serum and sodium ion in urine may also provide some information about kidney function, but creatinine is considered the most important laboratory test in this context. The option "kalium iron in serum" is not relevant to the assessment of kidney function and can be ruled out.Rate this question:

Renal failure with uremia is associated with each of the following except:
- A.
Fibrinous pericarditis
- B.
Hypercalcemia
- C.
Acute interstitial pneumonitis
- D.
Reduced erythropoietin manufacture
Correct Answer
D. Reduced erythropoietin manufactureExplanation
Renal failure with uremia is associated with various complications, including fibrinous pericarditis, hypercalcemia, and acute interstitial pneumonitis. However, reduced erythropoietin manufacture is not directly associated with renal failure and uremia. Erythropoietin is a hormone produced by the kidneys that stimulates the production of red blood cells in the bone marrow. In renal failure, the kidneys are unable to produce sufficient erythropoietin, leading to anemia. Therefore, the correct answer is reduced erythropoietin manufacture.Rate this question:

In patients not fasting, all of the mentioned parameters - triglycerides, LDL-ch, and HDL-ch - will change. Fasting is required to obtain accurate measurements of these parameters as it helps to eliminate the influence of recent food intake. When a person is not fasting, the levels of triglycerides, LDL-ch, and HDL-ch can be affected by the digestion and absorption of food, leading to fluctuations in their values. Therefore, all of these parameters will show changes in patients who are not fasting.Rate this question:

Cheilosis is defined as:
- A.
Club-shaped nails
- B.
Disorder of the lips, fissures around the corner of mouth
- C.
Inflammed tongue
- D.
Patchy marks around the nose and skin
Correct Answer
B. Disorder of the lips, fissures around the corner of mouthExplanation
Cheilosis is a disorder characterized by the presence of fissures or cracks around the corners of the mouth. This condition can cause discomfort and pain, especially when opening the mouth or eating. It is often associated with a deficiency in certain vitamins, such as riboflavin (vitamin B2) or iron. The symptoms of cheilosis can vary in severity, ranging from mild dryness and redness to more severe cracking and inflammation. Proper diagnosis and treatment of the underlying nutrient deficiency are important in managing and resolving this condition.Rate this question:

Koilconychia is:
- A.
Disorder of the lips, fissures around the corner of the mouth
- B.
Disorder of the hands, swan shaped fingers
- C.
Club-shaped nails
- D.
Inflammed tongue
Correct Answer
C. Club-shaped nailsExplanation
Koilonychia is a condition characterized by club-shaped nails. This means that the nails become abnormally thin and spoon-shaped, with a concave shape. This condition is often associated with iron deficiency anemia and can also be caused by other factors such as trauma or certain medical conditions. The nails may appear pale, brittle, and have a tendency to crack or split easily. Treatment involves addressing the underlying cause and may include iron supplementation and proper nail care.Rate this question:

Glossitis can be seen in:
- A.
IDA (iron deficiency Anemia)
- B.
Cholestasis
- C.
Diabetes mellitus
- D.
Haemolytic anemia
Correct Answer
A. IDA (iron deficiency Anemia)Explanation
Glossitis, which refers to inflammation of the tongue, can be seen in iron deficiency anemia (IDA). Iron deficiency affects the production of red blood cells, leading to a decrease in oxygen supply to the tissues, including the tongue. This can result in a swollen, smooth, and shiny appearance of the tongue, which is characteristic of glossitis. Cholestasis, diabetes mellitus, and hemolytic anemia, on the other hand, do not typically cause glossitis.Rate this question:

All are indicators of Hemolytic anemia except:
- A.
Elevated lactate dehydrogenase levels (LDH)
- B.
Unbound bilirubin
- C.
A decrease in protein haptoglobin (Hp)
- D.
Increased cobalamin
Correct Answer
D. Increased cobalaminExplanation
Increased cobalamin is not an indicator of hemolytic anemia. Cobalamin, also known as vitamin B12, is involved in the production of red blood cells but its levels do not directly indicate hemolytic anemia. Hemolytic anemia is characterized by the destruction of red blood cells, resulting in elevated lactate dehydrogenase levels, unbound bilirubin, and a decrease in protein haptoglobin.Rate this question:

What is the most common intrinsic cause of hemolytic anemia?
- A.
Target cells
- B.
Schistocytosis
- C.
Hereditary spherocytosis
- D.
Aniscocytosis
Correct Answer
C. Hereditary spHerocytosisExplanation
Hereditary spherocytosis is the most common intrinsic cause of hemolytic anemia. This is a genetic disorder characterized by the presence of spherocytes, which are abnormally shaped red blood cells that are more prone to premature destruction. The condition is caused by defects in proteins that are involved in maintaining the shape and stability of red blood cells, leading to their increased fragility and hemolysis. This results in a decrease in the lifespan of red blood cells and subsequent anemia.Rate this question:

A low Reticulocyte count can be due to:
- A.
B(12) deficiency
- B.
Bleeding
- C.
Hemolysis
- D.
None of the above
Correct Answer
A. B(12) deficiencyExplanation
A low reticulocyte count can be due to B(12) deficiency. Vitamin B(12) is essential for the production of red blood cells in the bone marrow. Without enough B(12), the bone marrow may not be able to produce an adequate number of reticulocytes, which are immature red blood cells. This can lead to a low reticulocyte count. Bleeding and hemolysis, the destruction of red blood cells, are not directly related to B(12) deficiency and would not typically cause a low reticulocyte count.Rate this question:

In Aplastic anemia the body makes too few of which type of cells?
- A.
WBC
- B.
RBC
- C.
Platelets
- D.
All the above
Correct Answer
D. All the aboveExplanation
In aplastic anemia, the body fails to produce enough red blood cells (RBCs), white blood cells (WBCs), and platelets. This condition is characterized by a decrease in the production of all three types of cells. As a result, individuals with aplastic anemia may experience symptoms such as fatigue, increased susceptibility to infections, and abnormal bleeding due to the low levels of RBCs, WBCs, and platelets in their bloodstream.Rate this question:

In Cobalamin deficiency Anemia:
- A.
Microcytic anemia (<80 fL)
- B.
Macrocytic anemia ( > 100 fL)
- C.
Decreased cobalamin
- D.
Increased cobalamin
- E.
Decreased homocystenine
- F.
Increased homocysteine
Correct Answer(s)
B. Macrocytic anemia ( > 100 fL)
C. Decreased cobalamin
F. Increased homocysteineExplanation
In Cobalamin deficiency anemia, the correct answer is macrocytic anemia (>100 fL). This is because cobalamin deficiency leads to impaired DNA synthesis, resulting in the production of larger than normal red blood cells. The decreased cobalamin levels are due to a deficiency in vitamin B12, which is necessary for the normal functioning of red blood cells. Additionally, cobalamin deficiency can cause an increase in homocysteine levels, leading to increased homocysteine.Rate this question:

Pernicious Anemia is:
- A.
A type of microcytic anemia
- B.
A type of Megalobastic anemia with folate deficiency
- C.
Megalobastic anemia which results from a lack of intrinsic factor in GI secretions needed for B12 absorption
- D.
Normocytic anemia which results from a lack of intrinsic factor in GI secretions needed for B12 absorption
Correct Answer
C. Megalobastic anemia which results from a lack of intrinsic factor in GI secretions needed for B12 absorptionExplanation
Pernicious anemia is a type of megaloblastic anemia that occurs due to a deficiency of intrinsic factor in GI secretions, which is necessary for the absorption of vitamin B12. This leads to impaired B12 absorption and subsequent deficiency, causing the characteristic large, immature red blood cells (megaloblasts) to form in the bone marrow. It is not a microcytic anemia because the red blood cells produced are actually larger than normal.Rate this question:
