The function of the left ventricle is to deliver:
Oxygentated blood into the aortic arch.
How many chambers are in the human heart?
The medical term for a heart attack is:
Myocardial infarction.
The receiving chambers of the heart are the:
The lower chamber of the heart are called:
the right atrioventricular valve is also called the:
Tricuspid valve.
The structure dividing the right and left halves of the heart is called:
The heart receives blood to supply its own needs via the:
Coronary arteries.
The relaxing phase of the cardiac cycle is called:
A cardiac cycle lasts approximately:
0.8 seconds.
The abbreviation for a test that monitors electrical impulses of the heart is:
Electrocardiogram. (ECG)
On an electrocardiogram (ECG) tracing, atrial activity is represented by the:
P wave.
On an electrocardiogram (ECG) tracing, which wave represents the activity of the ventricles?
QRS and T.
Blood vessels that carry blood away from the heart are called:
A person's pulse is created by a wave of pressure caused by:
Ventricular contraction.
What keeps the blood moving through the venous system?
Skeletal muscle movement and the opening and closing of valves within the veins.
An abnormally fast heart rate is called:
What is a normal blood pressure reading?
120/80 mm Hg
Systolic pressure measures pressure in the arteries during:
Ventricular contration.
The pulmonary circulation:
Carries deoxygentated blood to the lungs and returns oxygentated blood to the heart.
What represents the proper direction of blood flow in the circulatory system?
Arterioles, capillaries, and venules.
The right ventricle delivers blood to the:
Pulmonary artery.
The largest artery inthe body is the:
The pulmonary vein carries:
Oxygen-rich blood.
A sphygmomanometer is a(n):
Blood pressure cuff.
Tiny one-cell thick blood vessels are called:
What blood vessels carries oxygenated blood?
Pulmonary vein.
The outer layer of a blood vessel is called the tunica:
The internal space of a blood vessel is called the:
The layers of arteries differ from the layers of veins in that the:
Muscle layer is thick in arteries.
The inner layer of a blood vessel is called the:
What is the proper order of vein selection for venipuncture?
Median cubital, cephalic, and basilic.
The antecubital fossa is located:
Anterior to and distal to the elbow.
A blood clot circulating in the blood stream is called a(n):
The basilic vein is the third choice for venipuncture because it is:
More painful when punctured, near a major nerve, and near the brachial artery.
A phlebotomist is allowed to perform a venipuncture on an akle vein when:
The patient's physician has given permission to do so.
The longest vein in the body is the:
Great Saphenous.
What is the medical term for vein inflammation?
What is the name or abbreviation for a vascular system test?
Disseminated Intravascular Coagualtion. (DIC)
Lipid accumulation on the intima of an artery is called:
Inflammation of a vein in conjunction with formation of a blood clot is called:
Normal adult blood volume is approximately:
5 L.
Normal plasma is a:
Clear or slightly hazy, pale yellow fluid that is 90% water.
When the hand is prone, the cephalic vein in the antecubital area is located in line with the:
Little finger.
What is the most numerous cell in the blood.
Red blood cell.
What blood cell contains a nucleus?
A reticulocyte count measures immature :
Red blood cells.
Where are leukocytes produced?
Bone marrow.
What is the primary function of red blood cells?
Transport oxygen from the lungs to the tissues.
A leukocyte is a:
White blood cell.
What blood cell has the ability to pass through the blood vessel wall?
What formed element is first on the scene when an injury occurs?
What type of cells give rise to plasma cells that produce antibodies?
Neutrophils are sometimes called segs because they have segmented:
Platelets are also called:
An individual's body type is determined by the presence or absence of certain types of :
Antigens on the surface of the red blood cells.
Incompatible blood given to a patient because of miisidentification by a phlebotomist may result in the patient's:
Renal tubules being overcome by excess hemolysis and becoming totally dysfunctional.
Whole blood is made up of:
Formed elements suspended in plasma.
The liqud portion of a clotted specimen is called:
The clear liquid portion of an anticoagulated specimen that has been centrifuged is called:
How can you visually tell serum from plasma?
You cannot visually tell serum from plasma.
The most common anticoagulants prevent clotting by:
Inhibiting thrombin or binding calcium.
It is preferable to perform STAT chemistry tests on plasma rather than serum because plasma:
Is ready for testing sooner than serum.
What are some things to know regarding serum:
Serum is collected without an anticoagulant, serum is normally clear,pale yellow in color, and serum is suitable for most chemistry determinations.
A person with thrombocytosis has:
Abnormally increased platelets.
The process of coagulation is also called:
What is a test of the formed elements?
Complete Blood Count (CBC)
Hemostasis refers to:
The coagulation process.
An abnormal increase in white blood cells is called:
The extrinsic pathway of coagulation is initiated by:
Tissue Injury.
The first stage inthe hemostatic process is:
Lymph fluid is most likely:
Coagulation problems may result from live disease because the liver:
Manufactures coagulation factors.
Tests that measure the functioning of primary hemostasis are:
Platelet count and bleeding time.
Obstruction of a blood vessel by an embolus causes:
An embolism.
When the arm is in the anatomic position, the basilic vein is:
On the same side as the little finger.
Lymp fluid origniates from:
Excess tissue fluid.
A venipuncture site is normally healed by:
Platelet plug formation.
A malignant lymphoid tumor is called:
A test associated with the lymph system is:
Mononucleosis test.
Lymph fluid keeps moving in the right direction because of:
Valves in the lymph vessels.
What veins are antecubital veins:
Basilic,cephalic, and median cubital.
What test is performed on whole blood?
Complete blood Count. (CBC)
Blood away from heart
