- 4
- The medical term for a heart attack is:

- The relaxing phase of the cardiac cycle is called:
- Diastole.

- 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:
- Arteries.
- 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:
- Tachycardia.
- 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:
- Aorta.
- The pulmonary vein carries:
- Oxygen-rich blood.
- A sphygmomanometer is a(n):
- Blood pressure cuff.
- Tiny one-cell thick blood vessels are called:
- Capillaries.
- What blood vessels carries oxygenated blood?
- Pulmonary vein.
- The outer layer of a blood vessel is called the tunica:
- Adventitia.
- The internal space of a blood vessel is called the:
- Lumen.
- 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:
- Vein.
- 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):
- Embolus.
- 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?
- Phlebitis.
- 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:
- Atherosclerosis.
- Inflammation of a vein in conjunction with formation of a blood clot is called:
- Thrombophlebitis.
- 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?
- Leukocyte.
- 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?
- Leukocyte
- What formed element is first on the scene when an injury occurs?
- Platelet.
- What type of cells give rise to plasma cells that produce antibodies?
- Lymphocytes.
- Neutrophils are sometimes called segs because they have segmented:
- Nuclei.
- Platelets are also called:
- Thrombocytes.
- 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:
- Serum.
- The clear liquid portion of an anticoagulated specimen that has been centrifuged is called:
- Plasma.
- 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:
- Hemostasis.
- 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:
- Leulicytosis.
- The extrinsic pathway of coagulation is initiated by:
- Tissue Injury.
- The first stage inthe hemostatic process is:
- Vasoconstriction.
- Lymph fluid is most likely:
- Plasma.
- 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:
- Lymphosarcoma.
- 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)
- Arteries
- Blood away from heart
