Arterial blood gas (ABG) results of an intubated, mechanically ventilated patient are: pH 7.33; PaO2 50; PaCO 49; Bicarbonate 27.The nurse would anticipate the priority action would be to:
1. Increase respiratory rate and FiO2.
2. Increase IV fluids.
3. Add positive end expiratory pressure.
4. Decrease the respiratory rate and FiO2.
1
Rationale 1: This patient is in respiratory acidosis due to inadequate ventilation. The correct action would be to increase rate and FiO2.
Rationale 2: Administering IV fluids would not be appropriate because this would interfere with oxygenation.
Rationale 3: Positive end expiratory pressure is usually prescribed during the weaning process. This patient is not being weaned from the ventilator.
Rationale 4: This would not improve the patient's ABG or respiratory status.
