Final answer:
An abdominal aortic aneurysm is a weakened and bulging area in the abdominal aorta. Nurses should monitor symptoms and track the aneurysm's growth, with treatment ranging from medications to surgical repair if necessary.
Step-by-step explanation:
An abdominal aortic aneurysm is an enlargement of the abdominal aorta, which is the section of the aorta that runs through the abdomen. This condition occurs when the walls of the aorta weaken and bulge outwards, which can be life-threatening if the aneurysm ruptures.
Nurses should monitor for symptoms such as back pain, a pulsating feeling near the navel, and rapid heart rate, which could indicate an imminent rupture. They should also keep track of blood pressure and perform regular imaging tests to monitor the aneurysm's size and growth.
Treatment for an abdominal aortic aneurysm may include lifestyle changes, medication to lower blood pressure and reduce the risk of rupture, and in severe cases, surgery to repair the aneurysm. Two common surgical options are endovascular aneurysm repair (EVAR) or open abdominal surgery.
