A

Syringe

24
Q

True or false: Blood drawn in a syringe is immediately transferred to the appropriate evacuated tubes to prevent the formation of clots.

A

True

25
Q

True or false: It is acceptable to puncture the rubber stopper with the syringe needle and allow the blood to be drawn into the tube.

A

False

26
Q

for performing venipuncture from very small or very fragile veins often seen in children and in the geriatric population

A

Winged Blood Collection Set

27
Q

True or false: Always hold the apparatus by the needle wings and not by the tubing.

A

Venoscope II & Neonatal Transilluminator

34
Q

True or false: You can extract blood from patients while they are receiving intravenous medication because these solutions will not influence the chemical analysis.

A

False. Do not extract blood from patients while they are receiving intravenous medication because these solutions may influence the chemical analysis.
