Failure to remove the tourniquet before removing the needle:

Question

Quizplus · Accepted Answer

Leaving the tourniquet on for too long can restrict blood flow and cause pooling of blood, resulting in a hematoma. It is important to release the tourniquet before removing the needle to avoid this complication. Hemolysis (choice A) can be caused by a number of factors, including rough handling or shaking of the collection tube, but is not directly related to the use of a tourniquet. Discomfort (choice B) is subjective and can vary among patients, but it is not a significant clinical concern unless it leads to patient noncompliance or adverse reactions. Sample coagulation (choice D) can be affected by factors such as collection technique, anticoagulant type, and mixing of the sample, but again is not directly linked to tourniquet use.
