WHY DO WE DRAW FOR BLOOD CULTURES
- A.
  
  TO BE DRAWN IN A STERILE PROCEDURE
- B.
  
  DRAWN IN A NON STERILE PROCEDURE
- C.
  
  USE ALCHOL TO CLEANSE
- D.
  
  SHOULD BE LAST TUBE YOU DRAW
Correct Answer
A. TO BE DRAWN IN A STERILE PROCEDURE

Explanation
Blood cultures are drawn in a sterile procedure to prevent contamination and ensure accurate results. Sterility is crucial because any contamination can lead to false-positive results, making it difficult to identify the actual cause of infection. Drawing blood in a sterile manner involves using sterile equipment, such as needles and collection tubes, and following strict aseptic techniques to minimize the risk of introducing microorganisms into the sample. By drawing blood in a sterile procedure, healthcare professionals can improve the reliability of blood culture results and provide appropriate treatment for patients.

Correct Answer
B. 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.

Correct Answer
D. 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.

- D.
  
  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.

- D.
  
  USED IN BLOODBANK TO TEST BLOOD TYPE
Correct Answer
C. 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.

- B.

- D.
  
  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.

B. 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.

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.

Correct Answer
B. 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.

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.
