What is the effect of misplacing the tourniquet during venipuncture?

Misplacing the tourniquet during venipuncture can lead to both increased pain for the patient and difficulties in locating veins. When a tourniquet is applied improperly, it can create excessive pressure or may not effectively engorge the veins, which can make the procedure uncomfortable and painful for the patient. Additionally, if the tourniquet is placed too far from the intended puncture site or is left on for too long, it can lead to a condition known as "venous stasis," which makes the veins more difficult to visualize and palpate. This can complicate the venipuncture process as the healthcare provider may have trouble finding a suitable vein to draw blood or administer medication. Thus, the correct choice encompasses both the potential for pain and the difficulty in finding veins, highlighting the importance of proper tourniquet placement in venipuncture procedures.
