Explanation:

Question 9

The correct order for drawing blood into color - coded stoppered tubes (for venipuncture) follows the standard order: sterile (blood culture), blue (coagulation), red or red/black (serum), yellow (blood culture or special), green (heparin), lavender (EDTA), gray (glucose). Option a matches this standard order.

When performing venipuncture with a needle and syringe, forcing blood into the tube can cause hemolysis (rupture of red blood cells). Hematoma is a collection of blood outside a blood vessel, anemia is a low red blood cell count, and hemophilia is a bleeding disorder. So the correct answer is c.

When obtaining venous blood with a vacuum tube, the needle tip is inserted into the vein at a 15 - degree angle (for a straight entry into the vein, a 45 - degree angle is used for more superficial or difficult veins, but the standard for vacuum tube venipuncture is 15 degrees). So the correct answer is d.

Answer:

a. red or red/black, sterile, green, lavender, yellow, blue, gray
