## 문제

A nurse is assessing a 58-year-old client who was admitted with suspected pancreatic cancer. Which assessment finding would be most characteristic of this condition?

## 보기

1. Severe epigastric pain that improves with eating
2. Clay-colored stools and tea-colored urine
3. Progressive, painless jaundice **✔ 정답**
4. Right upper quadrant tenderness with Murphy's sign

**정답: 3**

## 해설

Progressive, painless jaundice with weight loss is the classic triad of pancreatic cancer, particularly when the tumor is in the head of the pancreas and obstructs the common bile duct. Clay-colored stools and tea-colored urine (보기2) are seen in biliary obstruction but not specific to pancreatic cancer. Severe epigastric pain that improves with eating (보기1) is more characteristic of peptic ulcer disease. Right upper quadrant tenderness with Murphy's sign (보기4) is typical of acute cholecystitis.

Understanding the Clinical Presentation of Pancreatic Cancer

The assessment finding most characteristic of pancreatic cancer, particularly when the malignancy involves the head of the pancreas, is progressive, painless jaundice. This classic presentation occurs due to the anatomical location of the tumor and its effect on the common bile duct.

Pathophysiology of Painless Jaundice

The common bile duct passes through the head of the pancreas before emptying into the duodenum. As a tumor grows in the pancreatic head, it can extrinsically compress or directly invade this duct, leading to obstructive jaundice. Because this obstruction develops gradually and is not associated with the acute inflammation seen in conditions like gallstones, the resulting jaundice is typically painless. The obstruction prevents conjugated bilirubin from being excreted into the gastrointestinal tract, causing it to accumulate in the bloodstream and deposit in tissues, including the skin and sclera [1].

Correlating Assessment Findings

This pathophysiological process directly explains the associated clinical signs. The backed-up conjugated bilirubin is filtered by the kidneys, leading to dark, tea-colored urine. Simultaneously, the lack of bilirubin reaching the intestines prevents the normal brown coloration of stool, resulting in pale, clay-colored stools. While the provided research abstract highlights a case of painless jaundice caused by metastatic disease rather than a primary pancreatic tumor, it explicitly confirms that this identical clinical picture—progressive painless jaundice and dark urine—is the typical and expected presentation of a primary pancreaticobiliary malignancy [2].

Why Other Options Are Incorrect

- Option 1: Severe epigastric pain that improves with eating is more characteristic of a duodenal ulcer. Pain from pancreatic cancer is typically described as a dull, gnawing ache that may radiate to the back and often worsens when lying supine, not one that improves with food intake.

- Option 2: While clay-colored stools and tea-colored urine are indeed signs of obstructive jaundice, they are a consequence of the obstruction and not the most characteristic initial finding. The hallmark sign that raises the highest suspicion for pancreatic cancer is the progressive, painless jaundice itself, which precedes and causes these secondary changes.

- Option 4: Right upper quadrant tenderness with a positive Murphy's sign is a classic physical exam finding for acute cholecystitis, where inspiration is abruptly halted by pain as the inflamed gallbladder contacts the examiner's hand. This is not associated with the typical presentation of a pancreatic malignancy.

Clinical Significance in Nursing Assessment

For a nurse assessing a client with suspected pancreatic cancer, recognizing the triad of progressive, painless jaundice, dark urine, and clay-colored stools is critical. This presentation indicates significant biliary obstruction, a condition that may require interventions such as percutaneous transhepatic biliary drainage (PTBD) to relieve the blockage and manage hyperbilirubinemia, as investigated in the context of pancreatic cancer patients [1]. The nurse must correlate these physical assessment findings with the underlying pathology to prioritize care and anticipate necessary medical interventions.References (research sources)

Pancreatic Cancer: Key Assessment CuesRecognizing the classic presentation of a pancreatic head tumor
The most characteristic finding is progressive, painless jaundice. This occurs when a tumor in the pancreatic head compresses the common bile duct, obstructing bile flow.

This obstruction leads to a predictable cascade: conjugated bilirubin backs up into the bloodstream, causing jaundice and tea-colored urine. The absence of bilirubin in the gut results in clay-colored stools.

CautionDo not confuse this with the painful jaundice of acute cholangitis or cholecystitis. A palpable, non-tender gallbladder (Courvoisier's sign) further supports a malignant obstruction.

## 핵심 개념

- **Courvoisier's Law** — States that in the presence of jaundice and a palpable, non-tender gallbladder, the cause is unlikely to be gallstones; often associated with malignancy like pancreatic cancer.
- **Acholic stools** — Clay-colored stools resulting from a lack of stercobilin, a breakdown product of bilirubin, in the gastrointestinal tract due to bile duct obstruction.
- **Conjugated bilirubin** — Water-soluble form of bilirubin processed by the liver; excreted by the kidneys in obstructive jaundice, causing dark urine.
- **Common bile duct obstruction** — Blockage of the duct carrying bile from the liver and gallbladder to the duodenum, often caused by a pancreatic head tumor compressing the duct.
- **Murphy's sign** — A sign of acute cholecystitis where deep inspiration during right upper quadrant palpation causes pain and inspiratory arrest.
