A client is undergoing an endoscopic retrograde cholangiopancreatography (ERCP) to evaluate the biliary system for suspected cholecystitis. Which of the following explanations should the nurse provide to the client about this procedure?

A. Mild, intermittent right upper quadrant (RUQ) pain is more characteristic of chronic cholecystitis rather than acute cholecystitis, which typically presents with severe pain.
B. Left lower quadrant (LLQ) pain with rebound tenderness is more indicative of conditions like diverticulitis, not acute cholecystitis.
C. Severe, colicky abdominal pain radiating to the right shoulder is the most common presentation of acute cholecystitis, often caused by gallbladder inflammation and obstruction of the cystic duct. The pain is due to irritation of the phrenic nerve, which supplies both the gallbladder and right shoulder.
D. Epigastric pain worsened by fatty meals is often seen in gallbladder disease but is more characteristic of biliary colic rather than acute cholecystitis.

Choice A reason:

While pain relief is important, it is essential to address the redness and swelling first, as they may indicate an infection or other complication related to the cholecystostomy.

Choice B reason:

This statement is correct. The nurse should notify the healthcare provider immediately about the client's symptoms and findings to ensure prompt evaluation and appropriate interventions.

Choice C reason:

Applying an ice pack may provide some relief for pain and inflammation, but it does not address the potential underlying cause of redness and swelling.

Choice D reason:

Changing the dressing and cleaning the insertion site is important for maintaining cleanliness, but the nurse should first notify the healthcare provider about the client's symptoms for further evaluation.
