45. Which of the following is used to stabilize a patient's arm during a venipuncture?
Answer: C
A phlebotomy wedge is used to stabilize a patient's arm during a venipuncture.
A phlebotomy wedge provides the necessary support and stabilization for the patient's arm, allowing for a more accurate and comfortable venipuncture procedure.
A) Arm restraints
Arm restraints may limit movement but are not specifically designed for venipuncture. They can cause discomfort and are not ideal for providing the stability needed during the procedure.
B) A blood pressure cuff
A blood pressure cuff is primarily used to measure blood pressure and can temporarily engorge veins, but it does not stabilize the arm; therefore, it is not suitable for ensuring that the arm remains still during venipuncture.
C) A phlebotomy wedge
A phlebotomy wedge is specifically designed to support and stabilize the arm during venipuncture. It safely positions the arm in a way that facilitates easier access to the veins, making the procedure smoother for both the patient and the healthcare provider.
D) A phlebotomy cart
A phlebotomy cart is a mobile unit that holds supplies and equipment used during venipuncture but does not provide any stabilization for the patient's arm. Its purpose is to organize tools rather than assist in the procedure itself.
Conclusion
The phlebotomy wedge is the most effective tool for stabilizing a patient's arm during venipuncture, as it is specifically designed for this purpose. Other options, while they may serve different functions, do not adequately provide the necessary support, making them unsuitable for stabilizing the arm during the procedure.
