The nurse is setting up hemodynamic monitoring. The purpose of the dynamic wave test, also known as the square wave test, is to determine whether the:
1. Transducer is accurately reflecting pressure in the vessel.
2. Line is at the correct level to measure hemodynamic pressures.
3. Radial artery can be used for monitoring.
4. Hemodynamic line has the correct amount of pressure in it.
Transducer is accurately reflecting pressure in the vessel.
Rationale: The purpose of the dynamic wave test, also known as the square wave test, is to determine whether the transducer is accurately reflecting pressure in the vessel. The phlebostatic access is used to determine the correct level to measure hemodynamic pressures. The Allen's test is used to measure whether the radial artery can be used for monitoring. The pressure should remain relatively constant at 300 mmHg for accurate hemodynamic monitoring.
