hard · NCLEX-RN Reduction of Risk Potential
The nurse assesses the client at 05:15 and notes severe hypotension, worsening tachycardia, and profound hypoxemia. Which nursing action is the safest and most urgent first response? Apply the response specifically to this case: mechanically ventilated COPD client with serial ABGs showing acute-on-chronic respiratory acidosis and changing compensation after ventilator adjustments.
- Disconnect the endotracheal tube from the ventilator circuit and allow the chest to decompress.
- Increase the ventilator positive end-expiratory pressure (PEEP) to 15 cmH2O to match the measured auto-PEEP.
- Increase the FiO2 to 100% and initiate a rapid 1,000 mL normal saline fluid bolus via a wide-open peripheral line.
- Perform immediate needle decompression of the left pleural space using a large-bore angiocatheter.
