Which imaging technique uses endoscopy combined with radiographic images to examine the bile and pancreatic ducts?
Percutaneous Transhepatic Cholangiography (PTC)
Endoscopic Ultrasound (EUS)
Magnetic Resonance Cholangiopancreatography (MRCP)
Endoscopic Retrograde Cholangiopancreatography (ERCP)
The Correct Answer is D
Rationale:
A. Percutaneous Transhepatic Cholangiography (PTC) involves inserting a needle through the skin into the liver to visualize bile ducts, not using endoscopy.
B. Endoscopic Ultrasound (EUS) uses an endoscope with ultrasound to image structures near the GI tract but does not combine with radiographic imaging of the ducts.
C. Magnetic Resonance Cholangiopancreatography (MRCP) uses MRI to noninvasively visualize bile and pancreatic ducts, without endoscopy.
D. Endoscopic Retrograde Cholangiopancreatography (ERCP) combines endoscopy with radiographic imaging to examine the bile and pancreatic ducts, allowing both diagnosis and therapeutic interventions.

Correct Answer is []
Explanation
Rationale:
- Potential Condition: The client with cirrhosis shows elevated ammonia (236 mcg/dL), confusion, agitation, and disorientation, which are classic findings of hepatic encephalopathy.
- Actions to Take:
- Lactulose is given to lower ammonia levels by promoting its excretion through the stool.
- Assessing for asterixis (flapping tremor of the hands) is key in identifying worsening encephalopathy.
- Parameters to Monitor:
- Neurologic status (orientation, cognition, responsiveness) should be monitored closely to evaluate improvement or deterioration.
- Safety measures are essential because confusion and agitation increase the client’s risk for falls and injury.
