When a patient has a shunt on their left arm, where should blood pressure be taken?

• A. Left arm
• B. Right arm
• C. Both arms
• D. Neither arm

Answer: (B)

When a patient has a shunt on their left arm, it is essential to avoid taking blood pressure readings on that arm to prevent any potential damage or complications to the shunt. Shunts are often used for hemodialysis access and require the continuity and integrity of the blood vessel to function properly. Therefore, taking blood pressure on the left arm could disrupt the flow or cause trauma to the shunt. In this scenario, the right arm is the appropriate site for measuring blood pressure since it is free from the shunt and is less likely to be affected by any procedure related to the vascular access in the left arm. This practice also ensures accurate readings without risking the shunt's function, making it the safest and most effective option for assessing the patient's blood pressure. The choices related to both arms and neither arm would not provide a safe or practical alternative, as the left arm's shunt dictates the need for caution and the right arm remains the only viable option.
