Wash and sterilize the lancet after each use
#10
Why is it important to wipe away the first drop of blood during capillary blood sampling?
To prevent contamination
To avoid clotting
To reduce the risk of infection
To maintain sample integrity
#11
Which of the following is a potential risk associated with capillary blood sampling in infants?
Decreased risk of hypoglycemia
Risk of nerve damage
Decreased risk of infection
