Question

the venous pulse found on physical exam of the neck is...
...monophasic, easily obliterated by light pressure, and decreased in the supine position.
...monophasic, not obliterated by light pressure, and increased in the supine position.
...biphasic, not obliterated by light pressure, and decreased in the supine position.
...biphasic due to left atrial and right atrial contractions.
...biphasic, easily obliterated by light pressure, and increased in the supine position.

Explanation:

The venous pulse in the neck is monophasic, easily obliterated by light pressure, and decreased in the supine position. This is because the jugular venous pulse reflects the pressure changes in the right atrium and is affected by factors like pressure and body - position. Light pressure can disrupt the venous flow and the supine position affects venous return and pressure.

Answer:

...monophasic, easily obliterated by light pressure, and decreased in the supine position.
