A nurse is discussing the use of ultrasound in diagnosing appendicitis. What should the nurse explain about the advantages of ultrasound in this context?
"Ultrasound provides detailed images of the appendix and surrounding structures."
"Ultrasound is the most definitive test for diagnosing appendicitis."
"Ultrasound is particularly effective in obese individuals."
"Ultrasound allows for direct visualization of the inside of the appendix."
The Correct Answer is C
A) Incorrect. While ultrasound can provide images of the appendix and surrounding structures, the level of detail may be limited compared to a CT scan.
B) Incorrect. A CT scan is considered the most definitive test for diagnosing appendicitis, not ultrasound.
C) Correct. Ultrasound is particularly effective in obese individuals because it does not rely on radiation and can provide clear images of the appendix in individuals with higher body mass index.
D) Incorrect. Ultrasound does not allow for direct visualization of the inside of the appendix. It provides external images of the appendix and surrounding area.
