Exam 5: Cardiodynamics and Hemodynamic Regulation

A patient with a PA catheter has an SVO₂ of 90%. For what should the nurse assess this patient?

A patient's hemodynamic parameters include the following: right atrial pressure (RAP) of 13 mm Hg, pulmonary artery wedge pressure (PAWP) of 8 mm Hg, systemic vascular resistance (SVR) of 1,000 dynes/sec/cm², cardiac output (CO) of 4.9 L/min, cardiac index (CI) of 3.5 L/min, and pulmonary vascular resistance (PVR) of 280 dynes/sec/cm². Which heart function should cause the nurse concern?

A patient is experiencing reduced afterload. What should the nurse identify as causes for this finding? Select all that apply.

The health care provider is planning to insert a pulmonary artery catheter into a patient. What should the nurse explain to the patient as being the purpose of this device? Select all that apply.

A patient has a pressure-monitoring device inserted after an acute myocardial infarction. Which action should the nurse take to minimize the risk of overdampened measurements? Select all that apply.

What should the nurse use to measure the contractility of the left side of a patient's heart?

The nurse wants to assess the oxygenation status of a patient who has been experiencing a gastrointestinal bleed. How should the nurse complete this assessment? Select all that apply.

A patient's systemic vascular resistance (SVR) has dangerously decreased. The nurse would expect to administer which medications?

Which observation indicates pulsus paradoxus on a patient's arterial pressure waveform?

When observing the waveform of an arterial line, the nurse notes the presence of a dicrotic notch. How should the nurse interpret this finding?

The nurse is monitoring the PA pressure of a mechanically ventilated patient. When should the nurse obtain the measurement to accurately assess this pressure?

The nurse suspects that a patient is experiencing cardiogenic shock. Which parameter indicates that the nurse's suspicion is correct?

How should the nurse calculate a patient's mean arterial pressure (MAP)?

Which value should the nurse recognize is normal for a patient's cardiac output?

A patient is admitted with atrial fibrillation. Why should the nurse identify interventions to address low cardiac output for this patient?

The nurse is concerned that the hand with an arterial line in the wrist is becoming ischemic. What did the nurse assess in this patient? Select all that apply.
