  • 2. 

    EDTA IS DRAWN FOR WHAT DEPT.?

    • BLOOD BANK

    • HEMATOLOGY

    • NA CITRATE

    • HEMATOCRIT

    Correct Answer
    A. HEMATOLOGY
    Explanation
    EDTA, or ethylenediaminetetraacetic acid, is a commonly used anticoagulant in blood collection tubes. It is drawn for the Hematology department because it helps preserve the integrity of blood samples by preventing clotting. This allows for accurate analysis of blood cell counts, morphology, and other hematological parameters.

    IN THE ORDER OF DRAW IF DRAWN INCORRECT WHAT COULD HAPPEN WITH THE ADDITIVES?

    • NOTHING JUST GET THE BLOOD AND GIVE TO THE LAB.

    • EDTA DRAWN BEFORE SST CAN CAUSE HEPARIN RESULTS TO BE LOWER

    • EDTA DRAWN BEFORE HEPARIN CAN CAUSE CALCIUM TO BE UNBOUND BY THE EDTA.

    • EDTA DRAWN BEFORE SST CAN CAUSE CALCIUM RESULTS TO BE LOWERED BECAUSE CALCIUM BECOMES BOUND BY EDTA. EDTA DRAWN BEFORE HEPARIN WILL CAUSE K TO BE INCORRECT.

    Correct Answer
    A. EDTA DRAWN BEFORE SST CAN CAUSE CALCIUM RESULTS TO BE LOWERED BECAUSE CALCIUM BECOMES BOUND BY EDTA. EDTA DRAWN BEFORE HEPARIN WILL CAUSE K TO BE INCORRECT.
    Explanation
    If EDTA is drawn before SST, it can cause calcium results to be lowered because calcium becomes bound by EDTA. Additionally, if EDTA is drawn before heparin, it will cause potassium (K) to be incorrect.

  • 5. 

    HEPARIN

    • ELECTROLYTES MAY ONLY BE DRAWN IN LI HEPARIN TUBE AND AMMONIUM TUBES SHOULD BE SUBMITTED IN LAB WITHIN 30 MIN

    • ELECTRLYTES CAN NOT BE DRAWN IN HEPARIN TUBES

    • AMMONIUM LEVELS SHOULD BE SUBMITTED WITHIN 60 MIN OF DRAW

    • TUBES SHOULD BE SUBMITTED TO LAB WHEN YOU HAVE TIME NO RUSH

    Correct Answer
    A. ELECTROLYTES MAY ONLY BE DRAWN IN LI HEPARIN TUBE AND AMMONIUM TUBES SHOULD BE SUBMITTED IN LAB WITHIN 30 MIN
    Explanation
    The correct answer states that electrolytes can only be drawn in a lithium heparin tube, indicating that this specific type of tube is necessary for accurate electrolyte testing. Additionally, the answer states that ammonium tubes should be submitted to the lab within 30 minutes, suggesting that there is a time constraint for these particular samples. Therefore, this answer provides important information about the proper collection and submission procedures for electrolytes and ammonium levels.

    WHAT IS NA CITRATE USED IN THE ORDER OF DRAW?

    • USED IN THE CHEMISTRY DEP. TO TEST FOR COAGULATION STUDIES

    • DRAWN IN COAGULATION STUDIES TO TEST FOR HEPARIN

    • DRAWN IN COAG STUDIES, SUGGEST DRAWING PLAIN RED TUBE BEFORE NA CITRATE TO CLEAR AWAY ANY TISSUE THROMBOPLASTIN.

    • USED IN BLOODBANK TO TEST BLOOD TYPE

    Correct Answer
    A. DRAWN IN COAG STUDIES, SUGGEST DRAWING PLAIN RED TUBE BEFORE NA CITRATE TO CLEAR AWAY ANY TISSUE THROMBOPLASTIN.
    Explanation
    NA Citrate is used in the order of draw in coagulation studies because it acts as an anticoagulant, preventing blood from clotting. Drawing a plain red tube before the NA Citrate tube helps clear away any tissue thromboplastin, which could interfere with the coagulation test results. This ensures accurate and reliable coagulation study results.

    NA FLUORIDE, K OAXLATE

    • STOPS GLYCOLYSIS THE FLUORIDE INACTIVATES RBC ENZYMES THAT DIGEST GLUCOSE

    • THE FLUORIDE ACTIVATES THE RBC ENYZMES THAT DIGEST WBC BUT HELPS GLYCOLYSIS

    • TEST FOR BLOOD CLOTS AND EDTA

    • USUALLT DRAWN FOR COAG TESTING

    Correct Answer
    A. STOPS GLYCOLYSIS THE FLUORIDE INACTIVATES RBC ENZYMES THAT DIGEST GLUCOSE
    Explanation
    The correct answer is "STOPS GLYCOLYSIS THE FLUORIDE INACTIVATES RBC ENZYMES THAT DIGEST GLUCOSE." This answer explains that fluoride stops glycolysis by inactivating the enzymes in red blood cells that digest glucose. This suggests that fluoride prevents the breakdown of glucose, which is an important step in glycolysis.

    WHEN YOU ARE USING GLASS TUBES YOU DRAW RED BEFORE NA CITRATE BLUE TUBE OR USING PLASTIC TUBES TUBE YOU WOULD DRAW NA CITRATE BLUE TUBE DISCARD AND DRAW NEW. WHY?

    • NA CITRATE DRAWN BEFORE HEPARIN CAN CAUSE COAG. RESULTS TO BE INCORRECT.

    • HEPARIN DRAWN BEFORE NA CITRATE CAN CAUSE COAG RESULTS TO BE INCORRECT

    • DOES NOT MATTER TEST RESULTS WILL BE THE SAME.

    • DEPENDS ON PATIENT IF EASY DRAW THROW AWAY TUBE BUT IF DIFFICULT KEEP TUBE.

    Correct Answer
    A. HEPARIN DRAWN BEFORE NA CITRATE CAN CAUSE COAG RESULTS TO BE INCORRECT
    Explanation
    Drawing heparin before drawing sodium citrate can cause incorrect coagulation results. Heparin is an anticoagulant, while sodium citrate is used as a coagulant. If heparin is drawn first, it can contaminate the sample, interfering with the coagulation process and leading to inaccurate results. Therefore, it is important to draw the sodium citrate tube before drawing the heparin tube to ensure accurate coagulation testing.

    EXPALIN THE ORDER OF DRAW FOR HEPARIN

    • TUBES WILL HAVE ONE OF THE FOLLWING SST HEPARIN, CITRATE HEPARIN, NA HEPARIN

    • TUBES OF ONE OF THE FOLLOWING LI HEPARIN, NA HEPARIN, AMMONIUM HEPARIN.

    • TUBES WILL HAVE HEPARIN AND EDTA

    • THERE IS NOT ORDER OF DRAW FOR HEPARIN

    Correct Answer
    A. TUBES OF ONE OF THE FOLLOWING LI HEPARIN, NA HEPARIN, AMMONIUM HEPARIN.
    Explanation
    The correct answer is "TUBES OF ONE OF THE FOLLOWING LI HEPARIN, NA HEPARIN, AMMONIUM HEPARIN." This suggests that the order of draw for heparin tubes is not specified and can include any of these types of heparin tubes.

    WHAT DOES CLOT/NON ADDITIVE DO?

    • USUALLY DRAWN FOR CHEMISTRY (SERUM) TESTING

    • THIS IS A GEL TUBE THAT GOES TO COAGULATION

    • USUALLY DRAWN FOR BLOOD BANK TO TEST SERUM

    • GOES TO ANY DEPARTMENT IN THE LAB FOR SERUM TESTING

    Correct Answer
    A. USUALLY DRAWN FOR CHEMISTRY (SERUM) TESTING
    Explanation
    The correct answer is "USUALLY DRAWN FOR CHEMISTRY (SERUM) TESTING". This is because the question asks what CLOT/NON ADDITIVE does, and the given answer states that it is usually drawn for chemistry (serum) testing. This suggests that CLOT/NON ADDITIVE tubes are commonly used for collecting blood samples for chemistry testing, specifically for testing the serum component of the blood.

    • ETHYLENEDIAMINEERTAACETATE

    • ETHYLENEDIAMINETERTAACETATE

    • ETHYLENEDIAMINETERACETATE

    Correct Answer
    A. ETHYLENEDIAMINETERTAACETATE
    Explanation
    The correct answer is ETHYLENEDIAMINETERTAACETATE. This is the correct spelling of the chemical compound EDTA (ethylenediaminetetraacetic acid). The other options have misspellings or incorrect arrangements of the letters.

    EXPLAIN THE SST IN THE ORDER OF DRAW?

    • TUBE WITH GEL CLOT AND CLOT ACTIVATOR AND IS A ADDITIVE TUBE

    • TUBE WITH SERUM AND CLOT ACTIVATOR AND IS A ADDITIVE TUBE

    • TUBE WITH GEL CLOT AND CLOT ACTIVATOR AND IS NOT A ADDITIVE TUBE.

    • TUBE THAT IS NOT A GEL TUBE AND IS A ADDITIVE

    Correct Answer
    A. TUBE WITH GEL CLOT AND CLOT ACTIVATOR AND IS A ADDITIVE TUBE
    Explanation
    The correct answer is the tube with gel clot and clot activator and is an additive tube. This is because the gel clot tube contains a gel barrier that separates the serum from the clot, allowing for easy separation of the two components. The clot activator promotes the formation of a clot, which helps in the separation process. Additionally, being an additive tube means that it contains a substance (such as a clot activator) that enhances the performance of the test being conducted.
