The nurse must do a heel stick on an ill neonate to obtain a blood sample. Which procedure is recommended to facilitate this?
a. Apply cool, moist compresses. c. Elevate the foot for 5 minutes.
b. Apply a tourniquet to the ankle. d. Wrap foot in a warm washcloth.
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.
