Sample interview questions: How do you handle patients who require intraoperative arterial pressure monitoring?

Sample answer:

Intraoperative Arterial Pressure Monitoring

1. Establish IV access: Insert a large-bore IV (minimum 18 gauge) into the patient’s radial or brachial artery to allow for arterial line insertion.
2. Prepare the insertion site: Sterilize the site with chlorhexidine or iodine and insert a local anesthetic (e.g., lidocaine) to minimize discomfort.
3. Insert the arterial line: Using the Seldinger technique, puncture the artery with an introducer needle and insert a guidewire. Thread the arterial line over the guidewire and remove the introducer.
4. Secure the arterial line: Use tape or a specialized dressing to secure the arterial line to the skin.
5. Zero the transducer: Calibrate the transducer to the level of the patient’s heart.
6. Monitor the waveform: Observe the arterial waveform for any abnormalities, such as dampened waveforms or arterial occlusion.
7. Titrate medications: Use the arterial pressure monitoring to guide medication administr… Read full answer
