Final answer:
The nurse's priority action after observing signs of impaired circulation around an elastic bandage is to release the bandage to restore proper circulation, then assess the pulse and palpate the extremity for further issues before considering a reapplication of the bandage.
Step-by-step explanation:
When a nurse observes signs of impaired circulation in an area surrounding an elastic bandage, the nurse's priority action should be to release the bandage. This is critical because signs of impaired circulation, which can include symptoms such as pain, numbness, swelling, or discoloration, indicate that the bandage may be too tight and blood flow is being restricted. Immediate release of the bandage can help restore proper circulation. Subsequently, the nurse should assess the pulse to check for blood flow and palpate the extremity to evaluate any further circulation issues. It may be necessary to reapply the bandage, ensuring it is snug but not too tight to impede blood flow.
Understanding that elastic bandages are used to prevent blood accumulation in the legs, as seen during prolonged standing or long-haul flights, underscores the importance of properly applying these bandages to avoid restricting venous return and causing potential complications. Therefore, the sequential steps after releasing the bandage would include assessing circulation and if appropriate, applying a new bandage with less pressure.
