A nurse is assessing a 65-year-old client with suspected pancreatic cancer. Which assessment finding would be most significant and require immediate attention?

## 보기

1. Mild epigastric pain that worsens after eating fatty foods
2. New onset of painless jaundice with dark urine and clay-colored stools **✔ 정답**
3. Nausea and occasional vomiting after large meals
4. Fatigue and decreased appetite over the past month

**정답: 2**

## 해설

Painless jaundice with dark urine and clay-colored stools is a classic sign of pancreatic head cancer requiring immediate evaluation due to bile duct obstruction. Other options are less specific or urgent.

Understanding the Clinical Significance

The question asks for the most significant finding requiring immediate attention in a client with suspected pancreatic cancer. While all options represent symptoms that can occur with pancreatic malignancies, the key is to identify the finding that signals a critical complication demanding urgent intervention.

Analyzing the Correct Answer: Painless Jaundice

The new onset of painless jaundice with dark urine and clay-colored stools is the most significant finding. This classic triad indicates obstructive jaundice, which occurs when a tumor blocks the common bile duct. In the context of suspected pancreatic cancer, a tumor located in the head of the pancreas can compress the distal bile duct, preventing the flow of bilirubin from the liver into the duodenum. This leads to a buildup of conjugated bilirubin in the bloodstream (causing jaundice), its excretion by the kidneys (causing dark urine), and the absence of bilirubin in the gut (causing clay-colored, acholic stools).

This finding is a medical urgency for several reasons. First, prolonged biliary obstruction can rapidly lead to severe complications such as cholangitis, coagulopathy from vitamin K malabsorption, and hepatocellular damage. Second, as highlighted in the provided evidence, malignancies of the distal biliary tract, which can mimic a pancreatic head tumor in presentation, are often clinically silent until they cause obstruction [1]. The onset of jaundice may be the first clear sign of a resectable tumor, and a prompt diagnostic workup is critical to determine if the patient is a candidate for curative surgical resection [1]. Endoscopic management, such as stenting to relieve the obstruction, is a priority to stabilize the patient and prevent further deterioration [2].

Why the Other Options Are Less Urgent

- Option 1: Mild epigastric pain that worsens after eating fatty foods. This symptom is suggestive of pancreaticobiliary pathology, as a tumor can cause ductal obstruction that becomes more symptomatic with the stimulus of a fatty meal. While important to report and investigate, this is a chronic pain pattern and does not represent an acute, life-threatening change in status.

- Option 3: Nausea and occasional vomiting after large meals. This is a nonspecific symptom that can result from gastric outlet obstruction if a large pancreatic tumor compresses the duodenum. However, the description is "occasional" and linked to large meals, indicating a partial and intermittent obstruction. This is less immediately critical than the complete biliary obstruction signified by jaundice and acholic stools.

- Option 4: Fatigue and decreased appetite over the past month. These are constitutional symptoms highly consistent with an underlying malignancy, representing a chronic, insidious process. While they contribute to the clinical picture of suspected cancer, they do not constitute an acute change that requires immediate, emergent attention in the same way that a new-onset obstructive biliary process does.

The nurse must prioritize the assessment finding that indicates a new and potentially reversible critical complication. The development of obstructive jaundice signals a transition from a chronic, insidious disease process to one with an acute, high-risk complication that necessitates rapid diagnostic and therapeutic endoscopy [2] to prevent irreversible harm.References (research sources)

Recognizing Malignant Biliary ObstructionPrioritizing Painless Jaundice in Pancreatic Cancer
The classic triad of painless jaundice, dark urine, and clay-colored stools is a red flag for malignant obstruction of the common bile duct, often from a tumor in the head of the pancreas. This finding requires immediate attention.

The obstruction causes a buildup of conjugated bilirubin in the bloodstream. The kidneys excrete this excess bilirubin, darkening the urine, while the absence of bilirubin reaching the gut results in acholic, pale stools.

CautionProlonged obstruction can rapidly progress to life-threatening cholangitis and coagulopathy from vitamin K malabsorption. Assess for Courvoisier's sign (a palpable, non-tender gallbladder) and anticipate urgent decompression via ERCP or PTC.

## 핵심 개념

- **Obstructive Jaundice** — Yellowing of skin/sclera due to blocked bile flow, leading to conjugated bilirubin buildup in blood.
- **Clay-colored stools** — Acholic stools lacking bilirubin pigment, indicating bile is not reaching the duodenum.
- **Courvoisier's sign** — A palpable, non-tender gallbladder in a jaundiced patient, often associated with malignant biliary obstruction.
- **Cholangitis** — Infection of the bile duct system, a life-threatening complication of prolonged biliary obstruction.
- **Coagulopathy** — Impaired blood clotting due to malabsorption of fat-soluble vitamin K in the absence of bile salts.
