Sudden changes in a resident’s status may indicate a life-threatening health problem and need to be addressed promptly. It is essential that the resident’s baseline status be known by staff so that changes can be identified. Pain, nausea, vomiting, dyspnea, bleeding, and other signs and symptoms also need to be noted. Changes in status demand assessment. Unusual findings and symptoms reported by the resident should be explored and thoroughly described, as should recent relevant events, such as a fall or administration of a new medication. This chapter describes the general changes that can indicate emergency conditions and explains the actions to take when an emergency condition occurs. It explores the signs of and nursing responses to possible: acute glaucoma, angina pectoris, congestive heart failure, detached retina, hypothermia, myocardial infarction, pneumonia, pulmonary embolism, and transient ischemic attack.
