Which of the following is the priority for a client with MODS and adult respiratory distress syndrome (ARDS)?
1. Maintain oxygen saturation 88% to 92%.
2. Provide mechanical ventilation with tidal volume of 10 ml/kg.
3. Administer sodium bicarbonate for pH of 7.31.
4. Provide frequent mouth care to prevent ventilator-associated pneumonia.
Maintain oxygen saturation 88% to 92%.
Rationale: The goal of therapy in shock is to maintain tissue perfusion with oxygen saturation 88% to 92% or more. Mechanical ventilation is provided with low tidal volumes of 4 to 6 ml/kg. Bicarbonate is given for pH<7.1. Frequent mouth care is an intervention, but not a higher priority than airway management.
