preferred method for infants and very young children (possibly younger than 2 years)

A

capillary puncture

50
Q

Infants have a small blood volume which means removing quantities of blood typical for venipuncture or arterial puncture can lead to

A

anemia

51

Obtaining blood from infants and children by venipuncture is difficult and may damage [?]

A

veins and surrounding tissues

59
Q

Take note that the larger the syringe,

A

the greater amount of vacuum obtained.

Syringe Method

62
Q

special procedures (blood is drawn and must be transferred to a different container)

A

Syringe Method

63
Q

Too large a vacuum has the tendency to pull too hard on the vein leading it to

A

collapse

64
Q

The use of syringe larger than [?] is not recommended.

A
