Accepted Answer

Producing hormones for endocrine signaling

Question 2

A patient presents with severe abdominal edema (ascites) and easy bruising. Laboratory tests reveal decreased plasma protein levels. Which condition is most likely responsible for these findings?

Accepted Answer

Cirrhosis of the liver

Question 3

Which plasma protein is primarily responsible for maintaining colloidal osmotic pressure in blood?

Accepted Answer

Albumin

Question 4

A patient exposed to carbon monoxide (CO) is at risk for hypoxia because CO binds to hemoglobin more strongly than oxygen. What is the name of the molecule formed when CO binds to hemoglobin?

Accepted Answer

Carboxyhemoglobin

Question 5

Which of the following equations correctly represents the relationship between blood viscosity ($$\eta) $$and water content in plasma?

Accepted Answer

$$\eta \propto \frac{1}{	ext{water content}}$$

Question 6

A patient with sickle-cell disease has erythrocytes that change shape under low oxygen conditions. Which abnormal hemoglobin is responsible for this phenomenon?

Accepted Answer

Hemoglobin S

Question 7

Which leukocyte is most abundant in blood and is primarily responsible for phagocytosing bacteria during acute infections?

Accepted Answer

Neutrophil

Question 8

A patient is diagnosed with acute lymphocytic leukemia. Which of the following best describes the cellular changes in this condition?

Accepted Answer

Rapid increase in immature, nonfunctional lymphocytes

Question 9

During hemostasis, which step involves the conversion of fibrinogen to fibrin, forming a stable clot?

Accepted Answer

Coagulation cascade

Question 10

Which of the following equations correctly represents the conversion of prothrombin to thrombin during coagulation?

Accepted Answer

$$	ext{Prothrombin} \xrightarrow{	ext{Factor Xa}} 	ext{Thrombin}$$

Question 11

A patient with hemophilia A is deficient in which clotting factor?

Accepted Answer

Factor VIII

Question 12

Which anticoagulant medication acts by inhibiting the production of vitamin K-dependent clotting factors in the liver?

Accepted Answer

Warfarin (Coumadin)

Question 13

A patient with blood type O- is considered a universal donor. Which of the following best explains why?

Accepted Answer

O- erythrocytes lack A, B, and Rh antigens, so they do not trigger agglutination in recipients

Question 14

A woman with Rh- blood is pregnant with an Rh+ fetus. Which condition may develop in subsequent pregnancies if not properly managed?

Accepted Answer

Hemolytic disease of the newborn (erythroblastosis fetalis)

Question 15

Which of the following best describes the role of antithrombin III in blood clotting?

Accepted Answer

It binds and inhibits factor Xa and thrombin, preventing further clotting

Question 16

A patient receives a blood transfusion and develops agglutination and hemolysis. Which of the following is the most likely cause?

Accepted Answer

Recipient antibodies bind to donor erythrocyte antigens

Question 17

Which of the following blood types can safely receive blood from a donor with type B-?

Accepted Answer

Type AB-

Question 18

Which leukocyte is primarily involved in responding to parasitic worm infections and mediating allergic reactions?

Accepted Answer

Eosinophil

Question 19

Which of the following best describes the process of erythropoiesis?

Accepted Answer

Production of erythrocytes from hematopoietic stem cells in red bone marrow

Question 20

A patient with deep vein thrombosis (DVT) is at risk for which life-threatening complication if a thrombus breaks off and travels to the lungs?

Accepted Answer

Pulmonary embolism
