When planning care for a patient on a mechanical ventilator, the nurse understands that the
application of positive end-expiratory pressure (PEEP) to the ventilator settings has which
therapeutic effect?
~Increased inflation of the lungs
~Prevention of barotrauma to the lung tissue
~Prevention of alveolar collapse during expiration
~Increased (FIO2 ) fraction of inspired oxygen concentration administration - ANS
Prevention of alveolar collapse during expiration
The nurse is caring for a 34-year-old woman with acute decompensated heart failure who has a
pulmonary artery catheter. Which assessment best indicates that the patient's condition is
improving?
~Cardiac output (CO) is 3.5 L/minute.
~Central venous pressure (CVP) is 10 mm Hg.
~Pulmonary artery wedge pressure (PAWP) is 10 mm Hg.
~Systemic vascular resistance (SVR) is 1500 dynes/sec/cm-5 . - ANS ~Pulmonary artery
wedge pressure (PAWP) is 10 mm Hg.
A 68-year-old male patient diagnosed with sepsis is orally intubated on mechanical ventilation.
Which action is most important for the nurse to take?
~Use the open-suctioning technique.
~Administer morphine for discomfort.
~Limit noise and cluster care activities.
~Elevate the head of the bed 30 degrees. - ANS ~Elevate the head of the bed 30 degrees.
The nurse is caring for a 65-year-old man with acute respiratory distress syndrome (ARDS) who
is on pressure support ventilation (PSV), fraction of inspired oxygen (FIO2) at 80%, and positive
end-expiratory pressure (PEEP) at 15 cm H2O. The patient weighs 72 kg. What finding would
indicate that treatment is effective?
~PaO2 of 60 mm Hg
~Tidal volume of 700 mL
~Cardiac output of 2.7 L/minute
~Inspiration to expiration ratio of 1:2 - ANS ~PaO2 of 60 mm Hg
