The distal lumen port is described by which feature on a Swan-Ganz catheter?

Explanation:
The defining feature of the distal lumen port is that it is the opening right at the catheter tip. This distal opening sits in the pulmonary artery channel and is the sensing port that provides the actual pressure readings for the pulmonary artery and, when the balloon is inflated and the catheter wedged, reflects the left atrial pressure as the wedge (PCWP). The balloon inflation is handled by a separate lumen, and while the measured pressures often come from what this distal port is sensing, the key descriptor is the opening located at the tip of the catheter.
