NHA Phlebotomy study
| Question | Answer |
|---|---|
| What are the two types of circulation in the heart? | 1.Pulmonary Circulation 2.Systemic Circulation |
| Pulmonary Circulation does? | Carries Deoxygenated blood from the right ventricle to the lings |
| Systemic Circulation does? | Carries oxygenated blood from the left ventricle throughout the body. |
| What are the two right valves of the heart? | Tricuspid Valve: atrioventricular valve Pulmonic Valve: Semi Lunar valve |
| What are the two left valves of the heart? | Mitral Valve: atrioventricular valve Aortic valve: A semi Lunar Valve |
| What are the hearts three layers? | Endocardium,Mycocardium,Epicardium |
| What are the 8 blood vessels? | Aorta, Ateries, Aterioles, capillaries,venules,veins,superior and inferior vena cavae |
| How many liters of blood are in the average adult body? | 5-6 liters |
| Plasma | Liquid portion |
| Formed elements | cellular portion consists of Erythrocytes,Leukocytes,Thrombocytes |
| What is the life span for Erythrocytes? | 120 days |
| What are the five Leukocytes? | Neutrophils,Lymphocytes,Monocytes,Eosinophils, Basophils. |
| Hemostasis | the process by which the blood vessels are repaired after injury. |
| what are the four stages of Hemostasis? | 1.Vascular Phase,2.Platelet Phase,3.Coagulation Phase,4.Fibrinolysis |
| Vascular Phase | Injury to blood vessels causing it to constrict slowing blood flow. |
| Platelet Phase | Platelets adhere to injured endothelial linning. Forms aggregation. |
| Aggregation | temporary platelet plug |
| Coagulation Phase | Converts temporary platelet plug to a stable fibrin clot. |
| Fibrinolysis | Breakdown and removal of clot. |
| APTT (Activated Partial Thromboplastin Time) | Used to monitor Heparin Therapy, and used to monitor intrinsic pathway |
| PT (prothrombin time) | Used to monitor Coumadin Therapy,this also evaluates extrinsic pathway. |
| What are the three major veins located in the antecubital fossa of the upper extremities? | Median Cubital Vein, Cephalic Vein, Basilic vein |
| Median Cubital Vein | Vein of choice, large and tends not to move. |
| Cephalic Vein | Second choice, has tendency to move, often only vein that can be palpated in the obese patient. |
| Unsuitable veins for venipuncturen are? | Sclerosed veins (hard cord like) Thrombotic Veins Tortuous Veins (winding or crooked veins, susceptible to infection) |
| Do not draw blood from | an arm with IV fluids running into it. |
| Hematoma | Blood accumulates in the tissue surrounding the vein. Causes= needle went through vein, or failure to apply pressure |
| Hemoconcentration | Increase of proportion due to tourniquet left to long |
| Phlebitis | Inflammation of a vein due to repeated venipuncture |
| petechiae | tiny non-raised red spots due to tourniquet being left to long. |
| Thrombus | Blood clot, usually consequence of insufficient pressure after withdrawl of needle |
| Thrombophlebitis | Inflammation of a vein with formation of a clot |
| Septicemia | systemic infection associated with the presence of a pathogenic organism introduced during venipuncture |
| Trauma | injury to underlying tissues caused by probing of needle |
| Edema | fluid retention in tissue |
| How far should you puncture when doing a capillary | no deeper than 2.0mm |
| where do you puncture on the heel | medial and lateral of the plantar surface of heel |
| what is the order of draw | yellow lightblue,red,green,lavender, gray |
| chemistry section is divided into three parts | Electrophoresis:analyzes chemical componets of blood. Toxicology: analyzes plasma levels of drugs and posions Immunochemistry:detects and measures substances such as hormones,enzymes, and drugs |
| profile | a group of tests ordered by physician |
| blood bank section | blood is collected stored and prepared for blood transfusion. |
| Serology (immunology) section | evaluates patients immune response through the production of antibodies. |
| Microbiology section | detection of pathogenic microorganisms in patient samples |
| urinalysis section | detects infection of the kidney and urinary tract |
| Hematology section | formed elements of the blood are studied whole blood is the most common test |
| external hemorrage | elevate the affected part above heart level and applying direct pressure to the wound |
| shock | insufficent return of blood flow to the heart |
| agents | infectious microotganisms that can be classified, viruses,bacteria,fungi, and parasites |
| portal of exit | how infectious agent leaves it's reservior |
| mode of transmission | specific ways whih microorganisms travel |
| 5 main modes of transmission | contact:direct and indirect Droplet,Airborne,Common vehicle,vectorborne |
| portal of entry | allows infectious agent access to the susceptible host |
| susceptible host | agent enterts a person who is not resistant or immune |
| medical asepsis | destruction of pathogenic micrpoorganisms after they leave the body |
| what is the solution fraction for disinfection | 1:10 bleach to water |
| negligence | failure to excersize the standard if care that a resonable person would give |
| what are the 4 D's of negligence | Duty of care Derelict:breach of duty of care Direct cause:legally recognizable injury occurs as a result of breach of duty Damage:wrongful activity must have cause the injury |
| tort | wrongful act that results in injury to a person |
| battery: | patient must give full consent before you touch them |
| invasion of privacy | release of medical records without the patients permission |
| defamation of character | injury to another persons reputation or name |
| Fasting Specimens | collection of blood when patient is in basil state refrained from excersize for 12 hrs prior drawing |
| timed specimen | measure blood levels of substances determine blood level medications monitor changes in a patients condition |
| Two hour postprandial test | evaluate diabetes mellitus |
| Oral Flucose Tolerance Test OGTT | diagnose diabetes mellitus and low blood sugar scheduled to begin 0700 and 0900 |
| 3 hour OGTT | test hyperglycemia |
| 5 hour OGTT | evaluate hypoglycemia |
| Therapeutic Drug Monitoring | monitors blood levels of certain medication |
| Blood Cultures | detect presence of microorganisms in patients blood |
| PKU | Ordered on infants to detect phenylketonuria causes mental retardation and brain damage |
| Cold Agglutinins | blood collected in red tube pre warmed in the incubator at 37 degrees celsius for 30 min |
| Chilled specimens | specimens must be chilled pronto in crushed ice or ice water mixture example arterial blood gases,lactic acid |
| Light sensitive specimens | protected from light wrapped in aluminum foil |
