The nurse is concerned that a patient's pulmonary artery has slipped into the right ventricle
What are the hallmarks of the waveform that the nurse observes on the monitor? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply. 1. Low diastolic pressure
2. No dicrotic notch
3. Continuous wedge waveform
4. Sharp upstroke, a plateau, and a rapid downstroke extending below the baseline
5. Smooth upstroke followed by a gradual downslope to the baseline
1,2
Rationale 1: One hallmark of right ventricular pressure is low diastolic pressure.
Rationale 2: One hallmark of right ventricular pressure is a lack of dicrotic notch.
Rationale 3: A continuous wedge waveform indicates the catheter is wedged in a pulmonary vessel.
Rationale 4: This describes the waveform caused by the square wave test.
Rationale 5: This describes a cardiac output curve.

A patient's status worsens and needs mechanical ventilation
The pulmonologist wants the patient to receive 10 breaths/min from the ventilator but wants to encourage the patient to breathe spontaneously in between the mechanical breaths at his own tidal volume. This mode of ventilation is called: a. assist/control ventilation b. controlled ventilation c. intermittent mandatory ventilation d. positive end-expiratory pressure
