For best practice, where should a resident's arm be placed while checking their pulse?

When checking a resident's pulse, the best practice is to have the arm placed at the side. This position helps to ensure that the blood flow is unobstructed, allowing for a more accurate measurement of the pulse. Placing the arm at the side reduces tension and strain on the arm and wrist, which can occur if the arm is positioned in less natural ways, such as being above the shoulder or under the head. Additionally, positioning the arm at the side can help to maintain the resident's comfort during the procedure, contributing to a more effective assessment of their health status. This is particularly important in a healthcare setting where reliable and consistent results are necessary for monitoring a patient's wellbeing.
