Question 1
Which observation indicates pulsus paradoxus on a patient's arterial pressure waveform?
◦ The pulse pressure is above 20 mm Hg on exhalation.
◦ There is a decrease of more than 10 mm Hg in the arterial waveform before inhalation.
◦ The waveform has tall, tented waves.
◦ There is a single, nonperfused beat.
Question 2
How should the nurse calculate a patient's mean arterial pressure (MAP)?
◦ Add the systolic pressure and two diastolic pressures and then divide by 3.
◦ Divide the diastolic pressure by the pulse pressure.
◦ Divide the systolic pressure by the diastolic pressure.
◦ Average three of the patient's blood pressures over a 6-hour period.
