Clinical Medical Assistant Exam Practice Question
What could be a potential complication of leaving a tourniquet on for too long during venipuncture?
Correct Answer: A
Rationale: Leaving a tourniquet on for an extended period during venipuncture can lead to hemoconcentration, where blood components become concentrated due to fluid loss. This can skew test results, making them less accurate.
Option B is incorrect; there are significant effects from prolonged tourniquet use, including hemoconcentration.
Option C is misleading; while clotting can occur, it is not a direct result of the tourniquet but rather a consequence of blood stasis.
Option D is incorrect as prolonged use of a tourniquet often causes discomfort and can lead to complications rather than enhancing patient comfort.
