Study Notes
Venipuncture Needle Selection
- Selecting the right gauge of the needle during venipuncture is crucial to prevent patient discomfort and ensure smooth blood flow.
Antiseptics in Venipuncture
- An antiseptic used in venipuncture procedures is EPA-registered sodium hypochlorite solutions.
- Iodine is not an antiseptic used in venipuncture procedures.
Tourniquet Purpose
- The purpose of using a tourniquet during venipuncture is to restrict blood flow, making it easier to access the vein.
Needle Disposal
- Needles should be disposed of using a sharps container after venipuncture procedures.
Evacuated Tube System (ETS) Tubes
- Additives are used in ETS tubes to prevent clotting, promote cell separation, and preserve blood samples.
- The purpose of a clot activator in an ETS tube is to promote clotting.
- Sodium Citrate 1:9 as an additive is indicated by a blue color tube cap.
- Lithium is used as an additive in blood collection tubes to prevent clotting.
- Potassium Oxalate Monohydrate and Sodium Fluoride as additives are indicated by a grey color tube cap.
Order of Draw
- Phlebotomists must follow the prescribed order of draw when collecting blood samples to prevent contamination and ensure accurate test results.
Phlebotomy Systems
- The main difference between evacuated tube systems and syringe systems in phlebotomy is the method of blood collection and storage.
- A component of the syringe system in phlebotomy is a needle and syringe.
- Winged infusion needles are used in phlebotomy for blood collection and are commonly used in syringe systems.
- Evacuated tubes are preferred over syringe systems for blood collection due to their ease of use, minimal blood waste, and reduced risk of contamination.
- The type of needle commonly used in evacuated tube systems for phlebotomy is a double-pointed needle.
- Color-coding in evacuated tubes used in phlebotomy is significant as it indicates the type of additive present in the tube.
