Which device should the nurse use to obtain electronic data regarding a patient’s respiratory status when the patient reports shortness of breath?

• A. Pulse Oximeter
• B. Incentive Spirometer
• C. Blood Pressure Monitor
• D. Glucometer

Answer: (A)

When a patient reports shortness of breath, you want data that directly reflects how well oxygen is getting into the blood. A pulse oximeter provides real-time, noninvasive data on oxygen saturation (SpO2) and often heart rate, giving a quick picture of respiratory status and uncovering potential hypoxemia. This information guides immediate decisions about oxygen needs and further assessment. The incentive spirometer focuses on deep breathing and lung expansion to prevent atelectasis; it doesn’t provide current oxygenation data. A blood pressure monitor measures arterial pressure, not oxygenation, and a glucometer measures blood glucose. Thus, the pulse oximeter is the device that best yields electronic data about respiratory status in this situation.
