Formative Quiz: Valsalva Maneuver (A&B)

Increase in intraabdominal pressure during Valsalva maneuver is caused by compressive forces caused by muscle contraction while forcefully exhaling with a closed glottis.

• True

• False

Increase in intraabdominal pressure during Valsalva maneuver is caused by compressive forces caused by muscle contraction while forcefully exhaling with a closed glottis.

• True

• False

A drop in blood pressure during Phase II is expected due to a decrease in venous return.

• True

• False

A decrease in cardiac output will lead to reflex bradycardia.

• True

• False

The myogenic reflex tells us that a decrease in blood pressure will cause the blood vessel wall to vasoconstrict.

• True

• False

There is a pressure overshoot during Phase III.

• True

• False

A release of intraabdominal pressure during Phase III leads to a sudden expansion of blood vessel diameter resulting to a decreased blood pressure.

• True

• False

A release of intraabdominal pressure during Phase III leads to a sudden expansion of blood vessel diameter resulting to a decreased blood pressure.

• True

• False

Cardiac output is not affected by changes in venous return.

• True

• False

An uncontrolled increase in blood pressure may lead to a stroke.

• True

• False
