Study Notes

Pre-Procedure Preparation

Wear all personal protective equipment (PPE) before entering the patient area
Perform hand hygiene:
- Wash hands with soap and water for 40-60 seconds
- Rub hands palm to palm with fingers interlaced and rotational rubbing of left thumb clasped in right palm
- Rinse hands with water and dry thoroughly with a single-use towel
Put on a gown, face protection (medical mask, face shield, or goggles), and gloves over gown cuffs

Collecting Blood Sample

Prepare the room with infectious waste bags and a leak-proof and puncture-resistant sharps container
Identify and prepare the patient, explaining the procedure and its purpose
Select the blood collection site, preferably at the bend of the elbow, and palpate the area to locate a visible, straight, and clear vein
Apply a tourniquet around the arm and ask the patient to form a fist to make the veins more prominent
Disinfect the area where the needle will be inserted using 70% isopropyl alcohol, waiting 30 seconds for it to dry
Insert the blood collector tube into the holder, avoiding pushing it past the recessed line on the needle holder
Anchor the vein by holding the patient's arm and placing a thumb below the intended insertion site
Perform the blood draw swiftly at a 30° angle, avoiding touching the disinfected site

Blood Collection Procedure

When blood starts flowing, ask the patient to open their hand
Once sufficient blood has been collected (minimum 5ml), release the tourniquet before withdrawing the needle
Give the patient a clean gauze or dry cotton wool ball to press gently on the site
Withdraw the needle gently and remove the blood collector tube from the holder
Put the needle into a leak-proof and puncture-resistant sharps container
If the sharps container has a needle remover, remove the needle following the instructions; otherwise, do not remove the needle from the holder

Post-Procedure

Stop the bleeding and clean the skin
Put an adhesive bandage on the site, if necessary
Put items that dripped blood or had body fluids on them into the infectious waste bag for destruction
Disinfect the blood holder tray and rack after use
Prepare the blood sample for transport by wiping the tube with a disposable paper towel and placing it in a plastic leak-proof packaging container
