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...

Metabolic acidosis is characterized by: - Answer a fall in the plasma HCO3- concentration and a low pH The patient is a 71 year old male who presents to the OR with a history of congestive heart failure. His history is positive for increasing shortness of breath, 3 pillow orthopnea, lower extremity edema, and dyspnea with mild exertion. Preoperative lab values are as follows (Arterial values): pH: 7.41, pCO2: 60, pO2: 50, HCO3-: 38.1, BE + 12, SaO2: 72%, Hgb/Hct: 7.6/23 Based on the above inf...
