The ICU nurse is caring for a client on a ventilator who is exhibiting respiratory distress. The ventilator alarms are going off. Which intervention should the nurse implement first? 1. Notify the respiratory therapist immediately. 2. Ventilate with a manual resuscitation bag. 3. Check the ventilator to resolve the problem. 4. Auscultate the client's lung sounds.

The client diagnosed with ARDS is transferred to the intensive care department and placed on a ventilator. Which intervention should the nurse implement first? 1. Confirm that the ventilator settings are correct. 2. Verify that the ventilator alarms are functioning properly. 3. Assess the respiratory status and pulse oximeter reading. 4. Monitor the client's arterial blood gas results.

3

Caused by too rapid a decrease of BUN and circulating fluid volume. It may result in cerebral edema and increased intracranial pressure. Early recognition of disequilibrium syndrome is essential. Pulling off fluid too fast, significant neurological change, slow down the fluids. Signs include: Nausea Vomiting Cerebral edema (↑ ICP- pulling off fluid too fast) Neuro checks Mannitol (cannot give if active bleeding) Change in LOC Seizure Agitation Advanced age is a risk factor

Disequilibrium Syndrome

Electrolytes increase when in this phase; increase BUN & Cret can throw off other electrolytes <400 mL/day/2-3 wks. temp. dialysis (permcath) very little output) or Anuric (no urine output) pale colored urine is almost clear. Daily weight is the best way to keep up with it. Trying to restore volume (Hyperkalemia will cause dysrhythmias PVC's that can lead to V-tach/need to be on cardiac monitor) Neuro checks Kussmaul's breathing
