The pt is diagnosed with pneumonia and is prescribed IV antibiotics for tx. The pt's swallow study determined that she should be on honey thick liquids and pureed foods. The spouse comes to visit the pt and notices the Swallow Precautions- thickened liquids sign and asks the RN what it means. The RN explains since the pt doesn't have adequate swallowing ability thin liquid may go into the trachea and then the lungs instead of the stomach and cause pneumonia. Suddenly, the spouse gets a shocked look on his face and says, Oh, no! I did that. I gave her pneumonia?

What is the RN's best response?
