Question 1

Which of the following best describes the primary function of albumin in blood plasma?

Accepted Answer

It maintains osmotic pressure, helping to regulate water balance in the blood.

Question 2

A patient with a deficiency in vitamin B$$_{12} is $$most likely to experience which of the following problems?

Accepted Answer

Question 3

Which of the following equations correctly represents cardiac output ($$CO$$)?

Accepted Answer

$$CO = Stroke\ Volume 	imes Heart\ Rate$$

Question 4

A person with type AB blood can safely receive blood from which of the following donors?

Accepted Answer

Type O, A, B, and AB donors.

Question 5

Which of the following white blood cells is primarily responsible for attacking parasites and is involved in allergic reactions?

Accepted Answer

Eosinophils

Question 6

During the blood clotting process, which step directly follows the formation of a platelet plug?

Accepted Answer

Coagulation

Question 7

A patient develops a stationary blood clot in a deep vein of the leg. What is this clot called, and what is the main risk if it dislodges?

Accepted Answer

Thrombus; risk of embolism traveling to the lungs

Question 8

Which of the following best explains why the left ventricle has a thicker myocardium than the right ventricle?

Accepted Answer

It pumps blood to the entire body, requiring higher pressure.

Question 9

A newborn develops hemolytic disease due to Rh incompatibility. Which scenario most likely led to this condition?

Accepted Answer

Rh$$^-$$ mother with Rh$$^+$$ fetus, mother developed anti-Rh antibodies during a previous pregnancy.

Question 10

Which of the following is a function of the spleen in the lymphatic system?

Accepted Answer

Removal of old red blood cells and immune surveillance

Question 11

A patient is experiencing persistent high blood pressure. Which of the following changes in blood vessels is most likely contributing to this condition?

Accepted Answer

Increased peripheral resistance due to vasoconstriction

Question 12

Which of the following best describes the role of antigen-presenting cells (APCs) in the immune response?

Accepted Answer

They present antigen fragments to T-cells to activate them.

Question 13

Which of the following is a correct sequence of events in the extrinsic pathway of blood clotting?

Accepted Answer

Tissue damage $$\rightarrow$$ Tissue factor release $$\rightarrow$$ Activation of clotting cascade

Question 14

Which of the following best explains why type O blood is considered the universal donor?

Accepted Answer

Type O blood lacks A and B antigens, so it does not trigger an immune response in recipients.

Question 15

A patient with a genetic deficiency in antithrombin is at increased risk for which of the following?

Accepted Answer

Excessive clotting due to lack of inhibition of thrombin

Question 16

Which of the following best describes the function of the coronary sinus?

Accepted Answer

It collects venous blood from the heart muscle and drains it into the right atrium.

Question 17

A patient is exposed to a pathogen for the first time and develops antibodies over several days. Which type of immunity is this?

Accepted Answer

Active immunity

Question 18

Which of the following best explains the effect of fever during an infection?

Accepted Answer

It inhibits pathogen growth and enhances immune cell activity.

Question 19

Which of the following is a correct description of the function of memory cells in the immune system?

Accepted Answer

They remember specific antigens and enable a faster response upon re-exposure.

Question 20

A patient with a mutation in the gene encoding for MHC proteins would most likely have which of the following problems?

Accepted Answer

Impaired ability to present antigens to T-cells, leading to reduced adaptive immune response.
