Answer to Question 1

ANS: B
Applying pressure to the site of venipuncture stops the bleeding and aids in coagulation. Pressure should be applied before bandage is applied.

Answer to Question 2

ANS: D
Before the blood sample is taken, the heel is heated with warm moist compresses for 5 to 10 minutes to dilate the blood vessels in the area. Cooling causes vasoconstriction, making blood collection more difficult. A tourniquet is used to constrict superficial veins. It will have an insignificant effect on capillaries. Elevating the foot will decrease the blood in the foot available for collection.
