67. Which of the following is used to stabilize a patients arm during a venipuncture
Answer: C
A phlebotomy wedge is used to stabilize a patient's arm during a venipuncture.
A phlebotomy wedge is specifically designed to provide support and stability to a patient's arm, facilitating a successful venipuncture procedure.
A) Arm restraints
Arm restraints are typically used to prevent movement for patients who may be agitated or unable to cooperate during medical procedures. While they can stabilize an arm, they are not designed specifically for venipuncture and may not provide the necessary support and positioning required for effective blood collection.
B) A blood pressure cuff
A blood pressure cuff is primarily used to measure blood pressure and can temporarily restrict blood flow to the arm. However, it does not securely stabilize the arm in the proper position for venipuncture, making it an unsuitable choice for this purpose.
C) A phlebotomy wedge
A phlebotomy wedge is specifically designed to hold the patient's arm in a stable position, providing the necessary support for healthcare professionals during venipuncture. This tool reduces movement and improves accuracy, making it the correct option for stabilizing the arm.
D) A phlebotomy cart
A phlebotomy cart is used for organizing and storing phlebotomy supplies and equipment, but it does not serve the function of stabilizing a patient's arm during the venipuncture process. Therefore, it is not applicable to the question being asked.
Conclusion
The phlebotomy wedge is the most effective tool for stabilizing a patient's arm during a venipuncture, as it is specifically designed for this purpose, enhancing both safety and accuracy. In contrast, the other options either serve different functions or do not provide the necessary support for the procedure.
