The nurse is analyzing a client's tracing for a pulmonary arterial wedge pressure. For which characteristic should the nurse analyze this tracing?
1. Dicrotic notch
2. Wandering baseline
3. Premature ventricular contractions
4. Higher and more pronounced pressure waveform,
1
Rationale 1: A dicrotic notch on a pulmonary arterial waveform strip is evidence of the pulmonary artery measure stepping up.
Rationale 2: A wandering baseline is not desirable. The transducer should be zeroed.
Rationale 3: Premature ventricular contractions would be seen on the right ventricular pressure tracing.
Rationale 4: Higher and more pronounced pressure waveform indicating a tracing from the right ventricle.
