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.

Vital Signs
- Temperature: 39°C (102.2°F) → fever worsened since admission (sign of possible infection).
- Heart rate: 122/min → tachycardia, worsened compared to earlier.
- Blood pressure: 106/54 mmHg → trending downward, may indicate fluid deficit/hypotension risk.
Nurse’s Notes
- Client lethargic → worsening mental status.
- Projectile vomiting → new onset, risk of dehydration and electrolyte imbalance.
- Abdominal cramping → possible gastrointestinal complication.
- Voiding dark, concentrated urine → sign of dehydration.
- Client requesting water → excessive thirst consistent with hyperglycemia/possible hyperosmolar state.
Correct Answer is B
Explanation
Rationale:
A. Right upper quadrant contains the liver and gallbladder; pain here is more typical of hepatobiliary disorders, not appendicitis.
B. Right lower quadrant is the correct location of McBurney’s point, found one-third of the distance from the anterior superior iliac spine to the umbilicus. Tenderness here is a classic sign of appendicitis.
C. Left lower quadrant pain is commonly associated with conditions like diverticulitis, not appendicitis.
D. Left upper quadrant contains the stomach, spleen, and pancreas tail; pain here suggests disorders of those organs, not appendicitis.
