The charge nurse has a Vigileo pulse contour cardiac output monitoring system available for use in the surgical intensive care unit. For which patient is use of this device most appropriate?Not quite, you're still learning!A patient with a history of aortic insufficiency admitted with a postoperative myocardial infarctionA mechanically ventilated patient with cardiogenic shock being treated with an intraaortic balloon pumpA patient with a history of atrial fibrillation having frequent episodes of paroxysmal supraventricular tachycardiaA mechanically ventilated patient admitted following repair of an acute bowel obstruction

he nurse is caring for a 100-kg patient being monitored with a pulmonary artery catheter. The nurse assesses a blood pressure of 90/60 mm Hg, heart rate 110 beats/min, respirations 36/min, oxygen saturation of 89% on 3 L of oxygen via nasal cannula. Bilateral crackles are audible upon auscultation. Which hemodynamic value requires immediate action by the nurse?No worries, learning is a process!Cardiac index (CI) of 1.2 L/min/m3Cardiac output (CO) of 4 L/minPulmonary vascular resistance(PVR) of 80 dynes/sec/cm-Systemic vascular resistance (SV) of 1800 dynes/sec/cm-5

25. Which statement about cardiovascular support during post-resuscitation management is NOT correct?Cardiac dysfunction can last for hours after resuscitationInvasive techniques should never be used to monitor blood pressure in individuals with poor perfusion or frequent arrhythmia. Shock and respiratory failure may produce decreased tissue perfusion and oxygenation, which may cause continued cardiovascular problems. You should monitor urine output

32) A patient with shock of unknown etiology whose hemodynamic monitoring indicatesa BP 92/54, pulse 64, and an elevated pulmonary artery wedge pressure has thefollowing collaborative interventions prescribed. Which intervention will the nursequestion?(a) Infuse normal saline at 250ml/hr(b) Keep head of bed elevated to 30 degrees(c) Give nitroprusside unless systolic BP is less than 90 mmHg(d) Administer dobutamine to keep systolic BP greater than 90 mmHg

The nurse is caring for a mechanically ventilated patient being monitored with a left radial arterial line. During the inspiratory phase of ventilation, the nurse assesses a 20 mm Hg decrease in arterial blood pressure. What is the best interpretation of this finding by the nurse?No sweat, you're still learning!The mechanical ventilator is malfunctioning.The patient may require fluid resuscitation.The arterial line may need to be replaced.The left limb may have reduced perfusion.
