QUESTIONS WITH ACCURATE SOLUTIONS
1.Explain why applying pressure after a blood draw is important in the context of hemostasis.It helps to cool the area and reduce swelling.It promotes the formation of a platelet plug to stop bleeding.It allows for the immediate analysis of the blood sample. It prevents the patient from feeling faint.
2.After a needle puncture, if a patient bleeds excessively and pulsating spurts and the blood is bright red, what is the most likely cause?an artery was punctured the patient has a hematoma the patient has a bleeding disorder the patient is on anticoagulant therapy 3.In phlebotomy, which department is responsible for analyzing specimens for lead testing?Hematology Microbiology Toxicology Immunology 4.Explain the significance of the reticulocyte count in the context of diagnosing anemia and assessing bone marrow function.It measures the total number of red blood cells in circulation.It indicates the percentage of immature red blood cells being produced by the bone marrow. 1 / 4
It evaluates the levels of iron in the blood.It assesses the presence of antibodies against red blood cells.
5.Explain why it is necessary to draw a discard tube before collecting the PT and PTT tubes if the previous tube did not fill completely.To avoid contamination from the previous sample To ensure that the blood sample is not hemolyzed To maintain the integrity of the blood sample To ensure the correct volume of blood is collected 6.In which area of laboratory diagnostics is DNA sample analysis primarily conducted?Hematology Molecular Diagnostics Microbiology Immunology 7.A patient scheduled for a fasting blood glucose test has not adhered to the NPO instructions. What potential impact could this have on the test results, and how should the phlebotomist proceed?The results will be accurate; proceed with the draw.The results may be invalid; reschedule the test after confirming NPO status.The results will be lower than normal; proceed with the draw.The results will be higher than normal; proceed with the draw.
8.Explain the significance of Troponin levels in the diagnosis of myocardial infarction.They indicate liver function 2 / 4
They help assess kidney health They are specific markers for heart muscle injury They measure blood glucose levels 9.Explain the role of the National Accrediting Agency of Clinical Laboratory Science (NAACLS) in phlebotomy training programs.NAACLS provides funding for phlebotomy programs. NAACLS develops new blood tests for clinical use.NAACLS sets standards and accredits educational programs in clinical laboratory science.NAACLS conducts blood draws for training purposes.
10.You must redraw a patient for potassium level because the first specimen was hemolysed. Knowing that the patient is a difficult draw, which of the following would you do to prevent hemolysis of the sample?Force the blood from a syringe into the vacutainer tube Draw blood into a syringe while quickly pulling on the plunger Use a 22g needle Use winged infusion set 11.Explain what the term 'icteric' indicates about a blood specimen and its potential implications for laboratory testing.It indicates the specimen is contaminated and cannot be used.It suggests the presence of excess bilirubin, which may affect test results.It means the specimen has been improperly stored and is unusable. It shows that the specimen is rich in lipids, affecting its clarity. 3 / 4
12.Explain the significance of molecular diagnostics in the context of phlebotomy and specimen processing.It focuses solely on blood typing.It involves the analysis of genetic material for disease detection.It is limited to testing for infectious diseases.It primarily deals with blood coagulation studies.
13.When a phlebotomist enters an airborne isolation room, the appropriate PPE would be gloves, N95 respirator gown, gloves, N95 respirator gown, gloves, mask gown, mask 14.What must a phlebotomist do when drawing blood from a patient with an IV in their arm?Use the opposite arm for the blood draw Identify the draw location on the requisition Notify the physician immediately Perform a capillary blood draw instead 15.Explain why Chlorhexidine Gluconate is not recommended for infants under two months of age.It is too expensive for use on infants.It can cause skin irritation and allergic reactions.Infants have a higher risk of systemic absorption and toxicity.It is less effective than other antiseptics for this age group.
