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 secure and stabilize a patient's arm, making it easier for healthcare professionals to perform venipuncture accurately and safely.
A) Arm restraints
Arm restraints may be used to limit a patient's movement, but they are not specifically designed for stabilizing the arm during venipuncture. Their primary function is to prevent movement that could result in injury or complications, rather than to provide the precise support needed for blood draws.
B) A blood pressure cuff
A blood pressure cuff is utilized primarily to measure blood pressure and can occasionally aid in venipuncture by engorging veins. However, it does not provide stabilization for the arm, which is crucial for successful venipuncture.
C) A phlebotomy wedge
A phlebotomy wedge is specifically engineered to stabilize the arm during venipuncture procedures. It allows for optimal positioning and support of the arm, facilitating a more accurate and efficient blood draw.
D) A phlebotomy cart
A phlebotomy cart is used to organize and transport phlebotomy supplies but does not serve the purpose of stabilizing a patient's arm during the venipuncture process. Its function is logistical rather than supportive.
Conclusion
The phlebotomy wedge is the most effective option for stabilizing a patient's arm during venipuncture, as it is designed specifically for that purpose. Other options, such as arm restraints, blood pressure cuffs, and phlebotomy carts, either do not provide necessary stabilization or serve different functions entirely, making them less suitable for this specific medical task.
