Final answer:
A client with DVT and an aPTT within the expected range is safe to discharge in the event of needing to clear beds for a disaster-induced influx of casualties. Clients with ataxia, acute abdominal pain indicating potential appendicitis, or significantly elevated pancreatic enzymes require immediate or continued care.
Step-by-step explanation:
In the scenario of a massive community disaster where stable clients must be discharged to accommodate new casualties, a nurse should identify the client that is safe to discharge based on the stability of their condition and the risk of imminent harm if not treated immediately. The safe client to discharge in this situation would be:
Option 2: A client who has deep-vein thrombosis (DVT) and an activated partial thromboplastin time (aPTT) within the expected reference range.
This client's condition is stable, as indicated by the regulation of aPTT, suggesting that clotting times are within the therapeutic range, and they might be managed with anticoagulation therapy on an outpatient basis. The other options represent clients with conditions that require immediate care or could potentially worsen quickly. Multiple sclerosis with ataxia might impair the client's ability to ambulate safely (Option 1), right lower quadrant pain with positive rebound tenderness could be indicative of appendicitis, which is a surgical emergency (Option 3), and elevated amylase and lipase levels suggest acute pancreatitis, which requires close monitoring and treatment (Option 4).
