ARRT Patient Care Practice Exam

An informed consent is required before performing which of the following exams?

1. UGI

2. BE

3. sialogram

4. renal arteriogram

The correct answer is: UGI

An informed consent is essential for procedures that involve a higher degree of risk or potential for complications. In the case of a UGI (Upper Gastrointestinal) series, the procedure often includes the use of contrast materials and carries risks such as allergic reactions or complications related to the sedation or preparation required for the examination. It is crucial to ensure that the patient understands the procedure, the reasons for it, and any potential risks involved before proceeding. While other exams like the barium enema (BE) and sialogram may also require some level of patient understanding and consent, they typically do not warrant the same level of detailed informed consent as procedures with more significant risks, such as the renal arteriogram. The renal arteriogram involves catheterization and manipulation of blood vessels, which can lead to complications such as bleeding or damage to the vessels. Therefore, although it may seem that a UGI would be the most invasive and risky, the renal arteriogram is actually more complex and generally requires clearer informed consent due to its invasive nature. In the context of informed consent, it is the patient's right to be fully informed about the procedure and its risks, thus ensuring they can make an educated decision about their healthcare.
