Phlebotomy Chapter 6: Cardiovascular System Key Terms Quiz

1. What is arrhythmia?

A condition related to high blood pressure.

A condition where the heart rate is consistently slow.

Irregularity in the heart rate, rhythm, or beat

A condition where the heart rate is consistently fast.

Arrhythmia refers to an irregularity in the heart rate, rhythm, or beat, which can manifest as the heart beating too fast, too slow, or in an irregular pattern. It is not specifically related to high blood pressure, although certain types of arrhythmias can sometimes be triggered by high blood pressure.

2. What is the Basilic vein?

Small capillary on the back of the leg.

Large vein on the inner side of the arm in the antecubital fossa

Artery in the neck that supplies blood to the brain.

Vein located near the hip joint.

The Basilic vein is a large vein located on the inner side of the arm in the antecubital fossa, not to be confused with small capillaries, arteries in the neck, or veins near the hip joint.

Explanation

The Basilic vein is a large vein located on the inner side of the arm in the antecubital fossa, not to be confused with small capillaries, arteries in the neck, or veins near the hip joint.

3. What is blood pressure?

The rate at which blood flows through the body.

An indication of the amount of blood in the body.

A measure of the force exerted by the blood on the walls of the vessels

The oxygen content of the blood.

Blood pressure specifically refers to the force exerted by the blood on the walls of the vessels, not the amount of blood, the rate of blood flow, or the oxygen content.

Explanation

Blood pressure specifically refers to the force exerted by the blood on the walls of the vessels, not the amount of blood, the rate of blood flow, or the oxygen content.

4. Where is the cephalic vein located?

Vein located in the upper thigh.

Vein located in the lateral part of the arm in the antecubital fossa

Vein located in the hand near the wrist.

Vein located in the medial part of the arm in the antecubital fossa.

The cephalic vein is specifically located in the lateral part of the arm, not the medial part or other areas mentioned in the incorrect options.

Explanation

The cephalic vein is specifically located in the lateral part of the arm, not the medial part or other areas mentioned in the incorrect options.

5. What is coagulation?

A chemical reaction that produces gas

Blood-clotting process

A type of cooking method

A type of dancing style

Coagulation refers to the process of blood clotting, which is essential for wound healing and stopping bleeding.

Explanation

Coagulation refers to the process of blood clotting, which is essential for wound healing and stopping bleeding.

6. What is a Crossmatch?

A type of mathematical equation used in geometry.

A method for matching clothes in a fashion ensemble.

Compatibility test performed to determine the suitablity of a unit of blood for transusion

A type of embroidery stitch.

A crossmatch is a crucial medical procedure to ensure that donated blood is compatible with the recipient's blood to avoid adverse reactions during a transfusion.

Explanation

A crossmatch is a crucial medical procedure to ensure that donated blood is compatible with the recipient's blood to avoid adverse reactions during a transfusion.

7. What is diastole?

The process of oxygenating blood in the lungs.

Contraction phase of the cardiac cycle.

Relaxation phase of the cardiac clycle

A type of exercise for increasing flexibility in muscles.

Diastole refers to the relaxation phase of the cardiac cycle, during which the heart muscle relaxes and the chambers of the heart fill with blood. This is essential for the heart to effectively pump blood throughout the body.

Explanation

Diastole refers to the relaxation phase of the cardiac cycle, during which the heart muscle relaxes and the chambers of the heart fill with blood. This is essential for the heart to effectively pump blood throughout the body.

8. What does ECG/EKG stand for?

Record of the electrical currents that correspond to each eent in the hear muscle contraction

Analysis of lung function

Measurement of blood pressure

Detection of brain waves

ECG/EKG specifically refers to the recording of electrical activity in the heart, not other physiological measurements like blood pressure, brain waves, or lung function.

Explanation

ECG/EKG specifically refers to the recording of electrical activity in the heart, not other physiological measurements like blood pressure, brain waves, or lung function.

9. What are atria?

Valves in the veins that prevent backflow of blood.

Small blood vessels that connect arteries to veins.

Upper changes of the heart that receive blood before it enters the ventricles

Tiny air sacs in the lungs responsible for gas exchange.

Atria specifically refer to the upper chambers of the heart that receive blood before it enters the ventricles. They play a crucial role in the circulation of blood throughout the body.

Explanation

Atria specifically refer to the upper chambers of the heart that receive blood before it enters the ventricles. They play a crucial role in the circulation of blood throughout the body.

10. What is the cardiac cycle?

A process involving the exchange of oxygen and carbon dioxide in the lungs.

A term used to describe the digestive system's functions.

One complete contraction and subsequent relaxation of the heart

A series of contractions in the muscles of the leg.

The cardiac cycle specifically refers to the sequence of events that occur in the heart during one heartbeat, including both contraction and relaxation phases.

Explanation

The cardiac cycle specifically refers to the sequence of events that occur in the heart during one heartbeat, including both contraction and relaxation phases.

11. What is the medical term for red blood cell?

Medical term for red blood cell RBC

Leukocyte

Thrombocyte

Neutrophil

Erythrocyte is the medical term specifically for red blood cells, while leukocyte refers to white blood cells, thrombocyte pertains to platelets, and neutrophil is a type of white blood cell.

Explanation

Erythrocyte is the medical term specifically for red blood cells, while leukocyte refers to white blood cells, thrombocyte pertains to platelets, and neutrophil is a type of white blood cell.

12. What is the extrinsic pathway?

Immune response pathway activated by foreign pathogens.

Pathway characterized by internal bodily processes unrelated to injury.

Coagulation pathway initiated by the release of thomboplastin from injured tissue

Blood clot formation pathway triggered by platelet aggregation.

The extrinsic pathway is a specific coagulation pathway that is initiated by the release of thomboplastin from injured tissue, unlike the other incorrect options provided.

Explanation

The extrinsic pathway is a specific coagulation pathway that is initiated by the release of thomboplastin from injured tissue, unlike the other incorrect options provided.
