Questions: 16) Normal renal venous flow is typically what near the IVC? 1 Point phasic augmentable pulsatile triphasic

The answer is the first one: phasic.

Explanation for each option:

1. Phasic: This is the correct answer. Normal renal venous flow near the inferior vena cava (IVC) is typically phasic, meaning it varies with the respiratory cycle. This is due to the changes in intra-abdominal pressure during breathing.

2. Augmentable: This term refers to the ability of blood flow to increase in response to certain maneuvers, such as compression of the limb in venous studies. It is not typically used to describe normal renal venous flow.

3. Pulsatile: Pulsatile flow is characterized by rhythmic variations in velocity and is usually associated with arterial flow rather than venous flow. While some venous flows can be mildly pulsatile due to proximity to the heart, this is not the typical description for renal venous flow near the IVC.

4. Triphasic: This term is used to describe a specific pattern of arterial blood flow, particularly in the context of peripheral arteries. It is not applicable to renal venous flow.

Summary: Normal renal venous flow near the IVC is typically phasic, reflecting the influence of respiratory movements on venous return.
