The nurse is reviewing the medical electronic record of a client with abdominal aortic aneurysm less than 3 cm in size. Which medical treatment should the nurse anticipate to be prescribed for the client?
A.
Ultrasound every six (6) months.
B.
Intravenous pyelogram yearly.
C.
Assessment of abdominal girth monthly.
D.
Repair of abdominal aortic aneurysm
The Correct Answer and Explanation is :
The correct answer is A. Ultrasound every six (6) months.
Explanation:
An abdominal aortic aneurysm (AAA) is a condition where the wall of the aorta, the largest blood vessel in the body, weakens and bulges out. Monitoring and managing an AAA is crucial to prevent its rupture, which can be life-threatening.
For an AAA less than 3 cm in size, the recommended approach generally involves regular monitoring rather than immediate surgical intervention. Here’s a detailed look at the rationale behind the choice of ultrasound every six months:
- Monitoring and Surveillance: For an AAA less than 3 cm, surgery is not typically indicated due to the lower risk of rupture associated with smaller aneurysms. Instead, the standard practice is to monitor the aneurysm regularly to ensure it does not grow or change significantly. An ultrasound is the preferred method for this surveillance because it is non-invasive, does not involve radiation, and provides accurate measurements of the aneurysm size.
- Frequency of Ultrasound: The guideline for AAA less than 3 cm is to perform an abdominal ultrasound every 6 to 12 months. This frequency allows for timely detection of any changes in the size of the aneurysm. In this case, every six months is a common recommendation to ensure any growth is detected early.
- Why Not the Other Options?:
- B. Intravenous pyelogram yearly: This test is used primarily to assess the urinary tract and kidneys, not for monitoring aneurysms. It is not suitable for AAA surveillance.
- C. Assessment of abdominal girth monthly: Measuring abdominal girth is not a recommended method for monitoring AAA size or growth. It might be used in other contexts but is not specific to AAA management.
- D. Repair of abdominal aortic aneurysm: Surgical repair is typically reserved for aneurysms larger than 5.5 cm or if there are symptoms or rapid growth. For an aneurysm less than 3 cm, surgery is not usually indicated.
In summary, regular monitoring with ultrasound every six months is a proactive approach to managing a small AAA, allowing for timely intervention if necessary.
