The mechanically ventilated client requires increasing PEEP for worsening ARDS. The order for PEEP is now at 20 cm of H2O. The nurse will need to contact the health care provider immediately if the client develops which of the following?
1. Lung sounds greater on one side than the other
2. Lung sounds with crackles
3. Diminished peripheral pulses
4. High-pressure alarm
Lung sounds greater on one side than the other
Rationale: A potential complication from increasing PEEP is a pneumothorax. The nurse needs to be alert to diminishing or absent lung sounds on one side of the chest. Crackles and diminished peripheral pulses would not be related to the pneumothorax. A low-pressure alarm would be more likely to sound if the client developed a pneumothorax.
