A nurse is caring for a client suspected to have cholecystitis. Which of the following diagnostic tests should the nurse anticipate as the first-line imaging study to confirm the diagnosis?

Abdominal computed tomography (CT) scan

Magnetic resonance imaging (MRI) of the gallbladder

Abdominal ultrasound

Endoscopic retrograde cholangiopancreatography (ERCP)

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

Choice A reason:

CT scans use X-rays, not magnetic fields, to create detailed cross-sectional images of the body. They involve radiation exposure.

Choice B reason:

This statement is correct. While CT scans use X-rays, the amount of radiation used in modern CT machines is relatively low and considered safe. The benefits of the diagnostic information obtained from the scan usually outweigh the risks associated with the small amount of radiation exposure.

Choice C reason:

The speed of the scan does not impact the radiation exposure. The amount of radiation used in a CT scan remains the same regardless of the scan duration.

Choice D reason:

CT scans use X-rays, not sound waves. Sound waves are used in ultrasound imaging, not in CT scans.

A. Elevated white blood cell count B. Impaired blood clotting C. Increased bilirubin levels D. Elevated serum amylase

Correct Answer is C

Explanation

Choice A reason:

Elevated white blood cell count may indicate inflammation or infection, but it is not directly related to jaundice and dark-colored urine, which are characteristic of increased bilirubin levels.

Choice B reason:

Impaired blood clotting is not directly related to jaundice and dark-colored urine. It may be a concern in liver disease but does not explain the specific manifestations mentioned in the question.

Choice C reason:

This statement is correct. Jaundice and dark-colored urine are indicative of increased bilirubin levels in the blood, which can occur in cholecystitis due to obstruction of the bile ducts.

Choice D reason:

Elevated serum amylase is more associated with pancreatitis rather than cholecystitis. It is not directly related to the clinical manifestations described.
