Which equipment is commonly used by a PCT to measure blood pressure?

The correct choice is the combination of a sphygmomanometer and a stethoscope, as these tools are specifically designed for measuring blood pressure. A sphygmomanometer is the device that consists of an inflatable cuff and a pressure gauge, which wraps around the arm and measures the pressure of the blood in the arteries when the heart beats (systolic pressure) and when the heart is at rest between beats (diastolic pressure). The stethoscope is used to listen to the sounds of the heart and blood flow, aiding in determining the precise measurements during the blood pressure assessment.

The other options include tools that serve different functions in patient care but are not appropriate for blood pressure measurement. A thermometer measures body temperature, while a pulse oximeter assesses oxygen saturation in the blood—neither of which provides blood pressure readings. The glucometer is used for measuring blood glucose levels, often paired with alcohol swabs for sanitization but not for blood pressure. A digital scale measures body weight and a heart rate monitor tracks heart beat rates, but neither is related to blood pressure assessment.
