A client is recovering from a cholecystectomy and reports feeling nauseous and experiencing episodes of vomiting. The nurse reviews the client's medication history and notes that opioid analgesics were administered for postoperative pain. Which of the following interventions should the nurse implement to address this issue?

Choice A reason:

Fasting for 12 hours is not required before an abdominal ultrasound. However, the client may be asked to avoid eating fatty or heavy meals before the procedure.

Choice B reason:

Filling the bladder with a gallon of water is unnecessary and not related to an abdominal ultrasound. A full bladder is required for pelvic ultrasounds, not abdominal ultrasounds.

Choice C reason:

Avoiding drinking liquids for 2 hours before the ultrasound is not necessary. In fact, a full bladder is preferred for better visualization during an abdominal ultrasound.

Choice D reason:

This statement is correct. To have a full bladder for the ultrasound, the client should drink 16 ounces of water about one hour before the procedure. A full bladder helps lift the intestines and improves the visualization of the gallbladder and surrounding structures.

Choice A reason:

Gastroenteritis typically presents with symptoms such as diarrhea, vomiting, and abdominal cramps. It does not cause jaundice or severe right upper quadrant pain.

Choice B reason:

This statement is correct. Cholecystitis with cholangitis is characterized by severe right upper quadrant abdominal pain, fever, and jaundice. Cholangitis is an inflammation of the bile ducts, often caused by gallstone migration and obstruction.

Choice C reason:

A urinary tract infection may cause symptoms such as burning urination and frequent urination but does not present with right upper quadrant abdominal pain or jaundice.

Choice D reason:

GERD is a condition characterized by acid reflux and heartburn. It does not cause severe right upper quadrant abdominal pain or jaundice.
