Hemodynamics Practice Questions 100% solved

Hemodynamics Practice Questions 100% solved The 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? a. Cardiac index (CI) of 1.2 L/min/m3 b.Cardiac output (CO) of 4 L/min c.Pulmonary vascular resistance (PVR) of 80 dynes/sec/cm- d.Systemic vascular resistance (SV) of 1800 dynes/sec/cm-5 - ANSA. Cardiac index (CI) of 1.2 L/min/m3 A cardiac index of 1.2 L/min/m3 combined with the identified clinical assessment findings indicate a low cardiac output with fluid overload (bilateral crackles) requiring intervention. The remaining hemodynamic values are within normal limits: cardiac output of 4 L/min; pulmonary vascular resistance of 80 dynes/sec/cm-5; and the systemic vascular resistance of 1800 dynes/sec/cm-5. 2. While caring for a patient with a small bowel obstruction, the nurse assesses a pulmonary artery occlusion pressure (PAOP) of 1 mm Hg and hourly urine output of 5 mL. The nurse anticipates which therapeutic intervention? a.Diuretics b.Intravenous fluids c.Negative inotropic agents d.Vasopressors - ANSb. Intravenous fluids Low pulmonary artery occlusion pressures usually indicate volume depletion, so intravenous fluids would be indicated. Administration of diuretics would worsen the patient's volume status. Negative in
