The nurse cares for a client diagnosed with respiratory failure.  Which assessments most accurately indicate acute respiratory distress syndrome (ARDS)?  Select all that apply (3).

The nurse cares for a client diagnosed with bilateral pneumonia.  The nurse prepares for intubation due to PaO2 of 55 mm Hg.  Which is the primary cause for the laboratory finding?

The repeat ABG reveals a pH of 7.38, PaCO2 to 55 mm Hg, PaO2 to 75 mm Hg, and SaO2 to 90%. What is the nurse’s best evaluation of this change?

The nurse cares for a client diagnosed with respiratory acidosis and the following ABG results.  Which is the best description of the compensation that will occur? pH: 7.33↓ PaCO2: 53↑ HCO3: 24 PaO2: 67↓

The nurse applies a non-rebreather mask at 10 LPM to the patient diagnosed with respiratory insufficiency.  Which is the expected effect of this action?

A 68-year-old patient with acute respiratory distress syndrome (ARDS) is on mechanical ventilation with the following settings: Mode: Assist-Control (AC) Tidal Volume (VT): 400 mL Respiratory Rate (RR): 14 breaths per minute FiO2: 1.0 (100%) PEEP: 10 cm H2O Peak Inspiratory Pressure: 45 cm H2O The most recent arterial blood gases (ABG) show: pH: 7.30 PaCO2: 62 mm Hg PaO2: 72 mm Hg HCO3: 30 mEq/L SaO2: 92% Given these results, which of the following is the priority nursing action?

A 32-year-old patient with acute respiratory distress syndrome (ARDS) is mechanically ventilated with the following settings: Mode: Assist-Control (AC) Tidal Volume (VT): 450 mL Respiratory Rate (RR): 18 breaths per minute FiO2: 0.80 (80%) PEEP: 12 cm H2O Peak inspiratory pressure: 40 cm H2O The patient’s most recent arterial blood gases (ABGs) show the following: pH: 7.28 PaCO2: 56 mm Hg PaO2: 65 mm Hg HCO3: 28 mEq/L SaO2: 90% Which of the following interventions would the nurse anticipate to improve this patient’s oxygenation and ventilation?

Given these settings and the ABG results, what is the most important assessment to make next to evaluate the effectiveness of her mechanical ventilation?
