Question

an elevated central venous pressure reflects...
...normal compensation with heart failure.
...volume overload.
...elevated blood pressure.
...the carotid arterial impulse.
...the monophasic venous pulse.

Explanation:

Elevated central venous pressure often indicates volume overload, as an excess of blood volume can increase the pressure in the central veins. Heart - failure compensation is not directly indicated by elevated CVP alone. Elevated blood pressure is related to arterial rather than central venous pressure. Carotid arterial impulse and monophasic venous pulse are not what elevated central venous pressure reflects.

Answer:

...volume overload.
