A client with suspected cholecystitis is scheduled for a hepatobiliary iminodiacetic acid (HIDA) scan. The client asks the nurse about the purpose of this test. Which of the following responses should the nurse provide?
"The HIDA scan will visualize the blood flow in your liver."
"This scan will assess the function and patency of your bile ducts."
"The HIDA scan will evaluate the motility of your small intestine."
"This scan will provide detailed images of your pancreas."
The Correct Answer is B
Choice A reason:
Visualizing blood flow in the liver is not the purpose of a HIDA scan. This type of scan is primarily used to assess the biliary system.
Choice B reason:
This statement is correct. A HIDA scan is used to assess the function and patency of the bile ducts. It involves injecting a radioactive tracer that is taken up by the liver and excreted into the bile. The scan can visualize the flow of bile and detect any obstruction or abnormality in the biliary system.
Choice C reason:
Evaluating the motility of the small intestine is not the purpose of a HIDA scan. It is used specifically for assessing the biliary system.
Choice D reason:
Providing detailed images of the pancreas is not the primary purpose of a HIDA scan, although it can sometimes provide some information about the pancreas if the tracer reaches the duodenum and enters the common bile duct.

Choice D reason:
Avoiding pain medications is not necessary before an abdominal ultrasound. The client can continue taking prescribed medications as usual.
Correct Answer is C
Explanation
Choice A reason:
Abdominal CT scan can provide detailed images, but it is not typically the first-line imaging study for diagnosing cholecystitis. It may be used if complications are suspected.
Choice B reason:
MRI of the gallbladder can provide high-resolution images, but it is not the first-line imaging study for diagnosing cholecystitis.
Choice C reason:
This statement is correct. Abdominal ultrasound is the first-line imaging study for diagnosing cholecystitis. It can visualize the gallbladder, detect gallstones, and assess for signs of inflammation, such as gallbladder wall thickening and pericholecystic fluid.
Choice D reason:
ERCP is an invasive procedure used to visualize the biliary and pancreatic ducts, but it is not typically used as a first-line diagnostic test for cholecystitis.
