Answer 1

1-Hematoma--hematoma is the most common adverse effect of venepuncture. hematoma is the collection of blood beneath the skin as a result of rupture of small blood vessels.

2-Hematoma can cause discomfort . so , as soon as hematoma is noted the phelobotomist should remove the needle and tourniquet and apply pressure at the site for a minimum of 3 minutes. cold compress will help reducing swelling .

3-In order to collect blood for a CBC ,  

• the area of the skin from where blood is collected is cleaned using an antiseptic wipe
• elastic band or tourniquet is placed around the upper arm to help the vein swell with blood
• insert needle into the vein and collects blood
• needle is removed and the area is covered using a bandage to prevent bleeding.
