Q: Which equation correctly represents the calculation of hematocrit ($$Hct) $$given the volume of red blood cells ($$V_{RBC}) $$and total blood volume ($$V_{total}$$)?

$$Hct = \frac{V_{RBC}}{V_{total}} \times 100$$

Question 1

Which plasma protein is primarily responsible for maintaining osmotic pressure in the blood, and where is it produced?

Accepted Answer

Albumin; produced in the liver

Question 2

A patient presents with a hematocrit of 60%. Which condition is most likely present, and what is a possible cause?

Accepted Answer

Polycythemia; due to chronic hypoxia

Question 3

Which of the following correctly lists the five types of leukocytes in order of their relative prevalence in normal blood (from most to least abundant)?

Accepted Answer

Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils

Question 4

Which of the following best describes the structural difference between platelets and other formed elements of blood?

Accepted Answer

Platelets are cell fragments derived from megakaryocytes, while erythrocytes and leukocytes are whole cells.

Question 5

A patient with type A negative blood receives type AB positive blood. What is the most likely outcome?

Accepted Answer

Agglutination and possible hemolytic reaction due to anti-B and anti-Rh antibodies.

Question 6

Which equation correctly represents the calculation of hematocrit ($$Hct) $$given the volume of red blood cells ($$V_{RBC}) $$and total blood volume ($$V_{total}$$)?

Accepted Answer

$$Hct = \frac{V_{RBC}}{V_{total}} 	imes 100$$

Question 7

Which leukocyte is primarily responsible for combating parasitic infections and is classified as a granulocyte?

Accepted Answer

Eosinophil

Question 8

What is the primary function of erythropoietin, and where is it mainly produced?

Accepted Answer

Stimulates erythrocyte production; produced in the kidneys

Question 9

Which of the following best describes the process of hemostasis?

Accepted Answer

The stoppage of bleeding involving vascular spasm, platelet plug formation, and coagulation

Question 10

A newborn develops erythroblastosis fetalis. Which scenario best explains this condition?

Accepted Answer

The mother is Rh-negative, the fetus is Rh-positive, and the mother has developed anti-Rh antibodies.

Question 11

Which of the following is a correct statement regarding the universal donor and universal recipient blood types, and why?

Accepted Answer

Type O negative is the universal donor because it lacks A, B, and Rh antigens.

Question 12

Which of the following best describes the breakdown of hemoglobin after erythrocyte destruction?

Accepted Answer

Hemoglobin is broken down into heme and globin; heme is converted to bilirubin, and globin is broken into amino acids.

Question 13

Which of the following disorders is characterized by uncontrolled proliferation of abnormal white blood cells?

Accepted Answer

Leukemia

Question 14

A patient with hemophilia is most likely to experience which of the following?

Accepted Answer

Excessive bleeding due to a deficiency in clotting factors

Question 15

Which of the following best explains why anti-Rh antibodies are not normally present in an Rh-negative individual?

Accepted Answer

Anti-Rh antibodies are only produced after exposure to Rh-positive blood.

Question 16

Which of the following is a function of platelets?

Accepted Answer

Initiating the clotting process by forming a temporary plug at the site of vessel injury

Question 17

Which type of anemia is caused by a deficiency of vitamin B12 due to lack of intrinsic factor?

Accepted Answer

Pernicious anemia

Question 18

Which of the following best describes the role of megakaryocytes in blood cell formation?

Accepted Answer

They fragment to release platelets into the bloodstream.

Question 19

Which of the following best describes the difference between hemostasis and coagulation?

Accepted Answer

Hemostasis is the overall process of stopping bleeding, while coagulation is the specific step involving the formation of a fibrin clot.

Question 20

Which of the following best describes the location of hematopoiesis in adults?

Accepted Answer

Red bone marrow of flat bones such as the sternum and pelvis
