Pancreatic Cancer

Pancreatic ductal adenocarcinoma (PDAC) High-yield Verified · Sep 2026

Pancreatic cancer is carcinoma arising from the pancreatic duct cells (pancreatic ductal adenocarcinoma), the most common type of pancreatic cancer and a leading cause of cancer death in the United States.

A head tumor squeezes the common bile duct, causing painless jaundice, dark urine, pale stools and itching. The tumor also causes pain, weight loss and malabsorption, and makes the blood clot (Trousseau syndrome). The nurse supports the few patients who can have a Whipple procedure: drains, glucose, delayed gastric emptying, fistula and a bloody drain that is an emergency. For everyone, the nurse teaches enzymes with every meal and snack, manages pain early and watches a stented bile duct for cholangitis.

What’s going wrong in the body

The normal physiology, where it fails, and why the body’s compensation backfires.

01 Where it starts — ductal cells, mostly in the head

"Pancreatic cancer refers to the carcinoma arising from the pancreatic duct cells, pancreatic ductal carcinoma, and is the fourth leading cause of cancer deaths in the United States." "More than 90% of adenocarcinomas of the pancreas are duct cell adenocarcinomas, with other types being cystadenocarcinoma and acinar cell carcinoma."

Location decides the symptoms and the operation. "Two-thirds arise in the pancreatic head; one-third arise in the rest (body and tail of the pancreas)." NCI: "Surgical approaches differ for masses in the head, body, tail, or uncinate process of the pancreas."

Silent early. "Pancreatic cancer does not have early signs or symptoms, making it very hard to detect in its early stages. Symptoms usually begin after the cancer has spread." At diagnosis, StatPearls reports 52% already have distant metastasis and 23% local spread.

Most pancreatic cancers are ductal adenocarcinomas; the two-thirds that arise in the pancreatic head announce themselves by blocking the bile duct, and tumor location also decides the operation.

02 How the tumor makes the classic picture

Jaundice. "Patients with adenocarcinoma of the pancreas typically present with painless jaundice (50%), usually due to obstruction of the common bile duct from the pancreatic head tumor." Bile backs up: "Patients can have weakness, pruritus from bile salts in the skin, anorexia, palpable, non-tender, distended gallbladder" with pale stools and dark urine. StatPearls illustrates the Courvoisier sign, "characteristically seen in pancreatic cancer," alongside this palpable non-tender gallbladder. Painless jaundice is the classic sign of a head tumor — not the most common symptom: "Weight loss occurs in about 90% of patients. Abdominal pain occurs in about 75% of patients."

Pain. "Pancreatic cancer is one of the most painful malignancies." NCI describes it as pain in the upper or middle abdomen and back.

New diabetes. "That is because pancreatic cancer destroys the ability of the pancreas to secrete hormones" — so a new diagnosis of diabetes in someone with no risk factors "may be an early sign of pancreatic cancer." Diabetes is also a risk factor.

Weight loss and malabsorption. NCI lists weight loss for no known reason and loss of appetite among the symptoms. "Frequently, malabsorption caused by exocrine insufficiency contributes to malnutrition. Pancreatic enzyme replacement can help alleviate this problem."

Clotting (Trousseau syndrome). "Cancer cells express increased levels of highly procoagulant TF" (tissue factor), and "Associations are often reported with gastrointestinal (particularly pancreatic and gastric), lung, and urogenital cancers." Recurrent or migratory clots can be the first clue: "Sometimes, patients may present with recurrent deep vein thrombosis (DVT) due to hypercoagulability that prompts clinicians to suspect cancer and a full workup of cancer."

Each classic finding maps to one thing the tumor does: bile-duct obstruction, local invasion, loss of endocrine and exocrine tissue, and tumor-driven clotting.

03 Resectable or not — and what a Whipple changes

"Surgical resection is the only current option for a cure, but only 20% of pancreatic cancer is surgically resectable at the time of diagnosis." NCI classes tumors as resectable ("tumors without vascular involvement"), borderline resectable, locally advanced or metastatic; StatPearls: "Metastatic disease in the liver, peritoneum, omentum, and extra-regional lymph nodes is considered unresectable." A head tumor gets a Whipple (pancreaticoduodenectomy); a body or tail tumor gets "distal pancreatectomy with splenectomy." Surgery "should be considered only alongside systemic therapy."

The Whipple. "The procedure involves the resection of the pancreatic head and uncinate process, duodenum, proximal jejunum, distal bile duct, gallbladder, and usually part of the stomach," then three anastomoses — pancreaticojejunostomy, hepaticojejunostomy and gastrojejunostomy. Afterward, exocrine insufficiency is managed with "the oral administration of pancreatic enzyme supplements." "Current mortality rates vary from 2% to 10%, with morbidity rates reported as high as 60%" (StatPearls).

Why the drains matter. The pancreaticojejunostomy can leak enzyme-rich fluid. "On postoperative days 1 and 3, the abdominal drain contents are evaluated for amylase levels. Elevated amylase (more than 3 times the upper limit of normal serum values) may indicate a pancreatic leak." Leaked enzymes can also "erode the ligated stump of the gastroduodenal artery," creating a pseudoaneurysm that can bleed catastrophically.

After a Whipple the nurse follows drain amylase and output, eating tolerance and glucose — and treats any sudden blood in a drain as a pseudoaneurysm until ruled out.

Causes & risk factors

Modifiable factors are teaching targets — the patient can act on them.

Cigarette smoking — "Smoking is a major risk factor for pancreatic cancer." StatPearls attributes 20% of pancreatic cancers to smoking. modifiable Family history / inherited genes — a first-degree relative or several second-degree relatives with pancreatic cancer or pancreatitis; BRCA1, BRCA2, PALB2, ATM; Lynch and Peutz-Jeghers syndromes. "Up to 10% of all pancreatic cancers are linked to inherited genetic syndromes." Chronic pancreatitis — "Long-term, or chronic, pancreatitis can cause damage to the pancreatic tissue and increase your risk of cancer." Obesity — "Obesity is linked to an increased risk of pancreatic cancer." modifiable Diabetes — a risk factor, and new-onset diabetes can also be a symptom Older age — "Nearly two-thirds of people are diagnosed at age 65 or older" Excessive alcohol — possible only — "Excessive alcohol use may be a risk factor," partly through chronic pancreatitis modifiable Workplace chemicals — some dry-cleaning and metalworking chemicals "may be linked," still unconfirmed

Signs & symptoms

Each finding tied to the mechanism that produces it — and the triage it calls for.

Painless jaundice — yellow skin and eyes, dark urine, light-colored stools, itching Hold & notify
Why: A head tumor blocks the common bile duct; bile salts in the skin cause pruritus. StatPearls: present in about 50%, with a palpable non-tender gallbladder (Courvoisier sign).
Pain in the upper or middle abdomen and back
Why: Local tumor growth; about 75% have abdominal pain (StatPearls). "Pancreatic cancer is one of the most painful malignancies."
Unexplained weight loss, loss of appetite, fatigue late
Why: Malabsorption from lost enzymes "contributes to malnutrition"; weight loss in about 90% (StatPearls).
New-onset diabetes in a person without diabetes risk factors early Hold & notify
Why: The tumor destroys insulin-secreting tissue; NCI: it "may be an early sign of pancreatic cancer."
Fatty stools, diarrhea, bloating Hold & notify
Why: Exocrine insufficiency — too few digestive enzymes, "often exacerbated by high-fat meals."
Nausea, vomiting, gas or bloating
Why: Listed by NCI among pancreatic cancer symptoms; gastric outlet obstruction is one of the problems palliative care may relieve (NCI).
One swollen, painful leg; tender cord along a vein Hold & notify
Why: Cancer-associated hypercoagulability (Trousseau syndrome). "Advanced pancreatic cancer makes your blood clot more easily." "Extensive extremity edema may indicate the presence of a deep vein thrombosis (DVT)." StatPearls: "immediate treatment is indicated at diagnosis."
Sudden shortness of breath in a patient with a known clot Report immediately
Why: Pulmonary embolism: "Untreated disease may lead to PE, which can be fatal."
Fever, right upper abdominal pain and jaundice — with confusion or low blood pressure (stented or blocked bile duct) Report immediately
Why: Acute cholangitis from obstructed biliary flow (stent occlusion is a named cause). "Acute cholangitis is a life-threatening medical condition that can be treated if identified early."
Recurring jaundice, pale stools, dark urine or itching after a biliary stent (no fever) Hold & notify
Why: The stent or duct may be blocking again; blocked flow is the precondition for cholangitis.

Diagnostics

Test In this disorder Normal
Screening in average-risk adults Grade D: "The USPSTF recommends against screening for pancreatic cancer in asymptomatic adults." Asymptomatic people with new-onset diabetes, smoking, obesity or chronic pancreatitis "are included in this recommendation." It "does not apply" to people with inherited syndromes or familial pancreatic cancer. Not recommended — by any method USPSTF 2019 (Grade D) —
Multidetector (multiphase) CT abdomen "multidetector computed tomography (MDCT) is the best imaging modality to diagnose and evaluate the extent of disease." "Ultrasound is of limited value in pancreatic imaging." MRI and endoscopic ultrasound are also used. Mass; extent of disease, vessel involvement and metastases —
Endoscopic ultrasound ± biopsy; ERCP with biliary stent EUS can biopsy the mass; "the placement of a biliary stent can help relieve symptoms of jaundice." A biopsy is not always needed before resection when the workup is complete. Tissue diagnosis; relief of jaundice —
Liver tests, bilirubin, amylase and lipase StatPearls lab picture; CA 19-9 and CEA are often elevated. Elevated liver tests and direct/total bilirubin (obstruction) —
CA 19-9 (tumor marker) Not a screening test. "No tumor-specific markers exist for pancreatic cancer. Markers such as serum cancer antigen (CA) 19-9 have low specificity," and "the presence of a normal CA 19-9 level does not preclude recurrence." High initial CA 19-9 and CEA "can indicate a poorer prognosis." Often high at diagnosis; rising level during or after treatment suggests progression NCI PDQ —
Resectability assessment (staging, staging laparoscopy) "To appropriately treat pancreatic cancer, it is crucial to evaluate whether the cancer can be resected." Before a Whipple, "a staging laparoscopy is conducted to exclude metastatic disease and ensure resectability." Resectable · borderline resectable · unresectable —
[WHIP] Drain fluid amylase Checked on post-operative days 1 and 3; a fistula is defined by this level "usually after postoperative day 3." More than 3 times the upper limit of normal serum amylase = possible pancreatic leak —

Complications

Black-box warning — most severe: ■ [WHIP] Gastroduodenal artery pseudoaneurysm — bloody drain Report immediately
"A gastroduodenal artery pseudoaneurysm represents a true surgical emergency, as rupture can result in life-threatening hemorrhage." "The sudden presence of blood in a pancreatic drain should be treated as a potential pseudoaneurysm until ruled out."
Mechanism: "pancreatic enzymes erode the ligated stump of the gastroduodenal artery" — often after a pancreatic leak.
Black-box warning — most severe: ■ [CHOL] Acute cholangitis Report immediately
"Charcot triad describes cholangitis as clinical findings of fever, right upper abdominal pain, and jaundice. The Reynolds pentad adds altered mental status and sepsis to the triad." "Many patients with acute cholangitis do not present with classic symptoms and signs."
"Initial medical therapy relies on early fluid resuscitation and appropriate antibiotic coverage. Delay in treatment can lead to septic shock." "In severely ill patients with sepsis, treatment is immediate or emergent biliary drainage"; "ERCP is the gold standard." "Without prompt treatment, these patients have a mortality rate of 50%." Malignancy raises the risk of death.
Warning: [POPF] Postoperative pancreatic fistula Hold & notify
Drain amylase above 3 times normal serum after surgery. "Grade A: biochemical leak, no clinical relevance" · "Grade B: persistent amylase-rich drainage that alters postoperative management" · "Grade C: fistula with organ failure."
"Most pancreatic leaks are grade A and resolve with appropriate drainage, resuscitation, and nutrition." Drains come out "once output is minimal, there is no evidence of a pancreatic fistula, and the patient can tolerate a regular diet."
Warning: [WHIP] Delayed gastric emptying Hold & notify
"Delayed gastric emptying is characterized by the inability to tolerate a solid diet or the continued need for a nasogastric tube several days postsurgery."
"Management typically involves extended nasogastric decompression, postpyloric feeding or parenteral nutrition, and prokinetic agents like metoclopramide." It "often results from a pancreatic leak and generally improves once the underlying issue is resolved."
Warning: [TS] Trousseau syndrome — migratory thrombophlebitis, DVT, PE Hold & notify
Superficial thrombophlebitis presents with "pain, erythema, and induration along the course of a superficial vein. A tender, cordlike, nodular segment is often palpable." "If the phlebitis is recurrent and migratory, clinicians should consider evaluating for an underlying malignancy."
"In patients with Trousseau syndrome, heparin is the preferred method of anticoagulation." It "may be refractory to anticoagulation in patients with cancer." Prognosis is poor — "a 1-year survival of only 12%," so "immediate treatment is indicated at diagnosis." Sudden dyspnea = possible PE (emergency).
Caution: [WHIP] New diabetes and exocrine insufficiency after resection Hold & notify
"Diabetes develops in approximately 20% of patients postoperatively," more often if glucose tolerance was impaired before surgery. Exocrine insufficiency "typically presents with symptoms such as diarrhea, bloating, and fatty stools."
Exocrine insufficiency is treated with oral enzyme supplements "to alleviate symptoms and improve nutrient absorption."
Black-box warning — most severe: ■ [TX] DPYD variant — fluoropyrimidine toxicity (5-FU, capecitabine) Report immediately
"Patients with the DPYD*2A variant who receive fluoropyrimidines may experience severe, life-threatening toxicities that are sometimes fatal." About 1% to 2% of people carry a pathogenic DPYD variant (NCI).
Caution: [WHIP] Bile leak and anastomotic stricture Hold & notify
"Most small bile leaks heal spontaneously, but more significant ones that appear in the immediate postoperative period may require reoperation." Hepaticojejunostomy strictures "are late complications from a narrow anastomosis, ischemia, or tumor recurrence."

Medications for this condition

Why each class is prescribed here — every card links to its full pharmacology page.

Antineoplastic / Chemotherapy Overview First-line High-alert
Oncology

[TX] "The two main regimens used are FOLFIRINOX and gemcitabine plus protein-bound paclitaxel." FOLFIRINOX (5-fluorouracil, oxaliplatin, irinotecan) "is extremely toxic, and only fit young patients can withstand it"; older or less fit patients "might be offered gemcitabine and protein-bound paclitaxel." Most possibly resectable patients get chemotherapy before surgery, and "Postoperative chemotherapy improves overall survival." Because palliative regimens have limited efficacy, "all newly diagnosed patients should consider enrolling in clinical trials." Olaparib maintenance can be considered for germline BRCA1/BRCA2 metastatic disease that has responded to first-line platinum-based therapy for more than 4 months. DPYD warning: patients with the DPYD*2A variant who receive fluoropyrimidines (5-FU, capecitabine) "may experience severe, life-threatening toxicities that are sometimes fatal." No doses here — see the class page.
Opioid Analgesics High-alert
Nervous · morphine

Cancer pain. "Pain management is extremely important. Pancreatic cancer is one of the most painful malignancies. Opioids, antiepileptics, and corticosteroids all are effective for pain relief." When medicine is not enough, "Celiac axis and intrapleural nerve blocks can provide highly effective and long-lasting control of pain for some patients." After a Whipple, epidural or intrathecal analgesia, nerve blocks and nonopioid agents are "essential" adjuncts.
Insulins High-alert
Endocrine

New diabetes. Diabetes can be a presenting sign (new-onset diabetes without risk factors) and "develops in approximately 20% of patients postoperatively" after a Whipple. The perioperative bundle includes "Ensuring normothermia and euglycemia." The sources give no insulin regimen — role only.
Antiemetics
Digestive / GI · ondansetron

Delayed gastric emptying after a Whipple is managed with nasogastric decompression, feeding support and "prokinetic agents like metoclopramide." Nausea and vomiting are also disease symptoms.
Anticoagulants High-alert
Cardiovascular · heparin

Trousseau syndrome: "In patients with Trousseau syndrome, heparin is the preferred method of anticoagulation"; clots may keep recurring despite anticoagulation. Perioperative: deep vein thrombosis prophylaxis is part of the Whipple bundle.

Beyond medications

  • Surgery — the only cure. Whipple (pancreaticoduodenectomy) for head tumors; distal pancreatectomy with splenectomy for body and tail tumors; staging laparoscopy first to exclude metastases. Only about 20% are resectable at diagnosis, and even after complete resection "ultimate control remains poor because of the high incidence of both local and distant tumor recurrence."
  • Pre-op optimization — nutrition support, "Correcting hyperbilirubinemia in patients that have biliary obstruction, which usually involves endoscopic biliary stenting," and prehabilitation for high-risk patients.
  • Whipple bundle — "Antibiotic prophylaxis within 30 minutes of skin incision," DVT prophylaxis, normothermia and euglycemia; closed suction drains; a nasogastric tube overnight (its use "is not mandatory"); early mobilization with physical and occupational therapy; dietitian input.
  • Pancreatic enzyme replacement (CREON label) — "Take CREON during meals and snacks"; about half the meal dose with a snack. "Swallow capsules whole." "Do not crush or chew CREON capsules or capsule contents." If the patient cannot swallow capsules, sprinkle the entire contents on a small amount of acidic soft food (for example, applesauce) and eat it immediately, with enough water or juice.
  • Palliation — "Surgical or radiological biliary decompression," relief of gastric outlet obstruction, pain control (including celiac nerve block) and psychological care.
  • Palliative care early — "Palliative care and a pain specialist should be involved in the care of these patients. Coordination of education of the family by the palliative nurse or provider is key because survival is severely reduced in most patients."
  • Nutrition at the forefront — "It is important to keep nutrition at the forefront of the patient's care, as nutrition can affect wound healing."

Nursing considerations

The RN-specific layer — each action paired with the reason it matters.

Assessment
Look for jaundice (skin, sclera), dark urine, pale stools and itching, and note a palpable non-tender gallbladder if found on exam.
Why: Painless jaundice with a palpable non-tender gallbladder is the classic head-tumor picture from bile-duct obstruction.
Track weight, intake and stool pattern (fatty stools, diarrhea, bloating).
Why: Weight loss affects about 90%; fatty stools and bloating signal exocrine insufficiency that enzymes can treat.
Check blood glucose and note new-onset diabetes.
Why: New diabetes can be an early sign, and about 20% develop diabetes after a Whipple.
After a Whipple: monitor each drain (amount, color, character) and the ordered drain-amylase results; watch NG output, bowel function and diet tolerance.
Why: Drain amylase above 3 times normal serum suggests a leak; inability to tolerate solids signals delayed gastric emptying; sudden blood in a drain is an emergency.
Assess legs for swelling, pain or a tender cord, and breathing for sudden dyspnea.
Why: Pancreatic cancer causes a hypercoagulable state (Trousseau syndrome); an untreated clot can become a fatal PE.
In a patient with a biliary stent, watch for fever, right upper abdominal pain and jaundice, plus confusion or hypotension.
Why: Stent occlusion is a named cause of cholangitis, which is "a life-threatening medical condition."
Interventions
Sudden blood in a pancreatic drain: stay with the patient, check vital signs and notify the surgeon immediately as an emergency.
Why: It "should be treated as a potential pseudoaneurysm until ruled out" — rupture "can result in life-threatening hemorrhage."
Septic cholangitis signs: escalate at once, start ordered fluids and antibiotics, and prepare for urgent biliary drainage (ERCP).
Why: "Delay in treatment can lead to septic shock"; severely ill patients need "immediate or emergent biliary drainage."
Give analgesia as ordered and reassess; report pain that medication does not control.
Why: "Pain management is extremely important"; celiac axis nerve blocks can give "highly effective and long-lasting control of pain for some patients."
Give enzymes with every meal and snack, swallowed whole; for a patient who cannot swallow capsules, sprinkle the entire contents on a small amount of acidic soft food such as applesauce — never crush or chew the capsules or their contents.
Why: CREON label: take "during meals and snacks," "Swallow capsules whole," "Do not crush or chew CREON capsules or capsule contents."
Report increasing drain output, a drain amylase result above 3 times normal serum, or new signs of organ failure.
Why: Drain amylase above 3 times normal serum may indicate a pancreatic leak; grade B leaks alter postoperative management and grade C involves organ failure.
Give DVT prophylaxis and anticoagulation as ordered and report bleeding.
Why: Heparin is preferred in Trousseau syndrome; prophylaxis is part of the Whipple bundle.
Patient and family teaching
Take enzymes with all meals and snacks; if a dose is missed, take the next dose with the next meal or snack. Report ongoing fatty stools or diarrhea.
Why: Enzymes let the body digest and absorb food; persistent malabsorption may need a dose change by the prescriber.
Report new jaundice, dark urine, pale stools or itching — and go to the emergency department for fever with jaundice and abdominal pain, confusion, or sudden shortness of breath.
Why: Blocked stents can cause life-threatening cholangitis; sudden dyspnea may be a pulmonary embolism.
Check blood glucose as taught and report high readings.
Why: New diabetes is common after a Whipple and can occur with the disease itself.
Quitting smoking, limiting alcohol and keeping a healthy weight lower risk — but "Nothing can prevent pancreatic cancer." Relatives with a strong family history should discuss their risk with a provider.
Why: NCI risk guidance; family history and inherited genes raise risk, and the USPSTF screening recommendation does not apply to people with inherited syndromes or familial pancreatic cancer.
Accept palliative care and psychological support alongside cancer treatment.
Why: NCI lists "Psychological care to address the potentially disabling psychological events associated with the diagnosis and treatment of pancreatic cancer" among palliative measures.

How a real nurse thinks

The clinical-judgment loop, worked for a typical presentation — reasoning, not reference.

  1. 1
    Recognize cues

    Sudden fresh blood in a pancreatic drain on post-op day 3, with tachycardia, a falling blood pressure and lightheadedness. The high glucose is a secondary cue.

  2. 2
    Analyze cues

    StatPearls: "The sudden presence of blood in a pancreatic drain should be treated as a potential pseudoaneurysm until ruled out." Leaked pancreatic enzymes can erode the gastroduodenal artery stump, and rupture "can result in life-threatening hemorrhage." The hemodynamic change fits bleeding.

  3. 3
    Prioritize

    Hemorrhage risk comes first — this is "a true surgical emergency." Glucose management and routine drain teaching wait.

  4. 4
    Generate solutions

    Stay with the patient, keep him monitored, call the surgeon immediately, and prepare for the surgeon’s orders. Do not wait for the POD 3 amylase result.

  5. 5
    Take action

    SBAR: 64-year-old POD 3 Whipple; fresh bright red blood now in the pancreatic drain; BP 104/64 down from 126/78, HR 118, lightheaded. Concern for gastroduodenal artery pseudoaneurysm — requesting immediate bedside evaluation.

  6. 6
    Evaluate

    Reassess vital signs, drain output and mental status frequently until the surgical team takes over; then resume glucose monitoring and treatment as ordered.

Scenario — you’re the nurse

Work each question before revealing the answer. Rationales explain the wrong options too.

Surgical unit · post-op day 3 after Whipple, 0900

A 64-year-old man who presented with painless jaundice, dark urine and itching was found to have a resectable adenocarcinoma of the pancreatic head. He had a biliary stent before surgery and a Whipple procedure 3 days ago. He has two closed suction drains, an epidural and a new insulin order for post-op hyperglycemia.

POD 1 drain amylase — normal; POD 3 drain amylase — pending
0600 — drain output about 30 mL/shift, serous; BP 126/78 · HR 86 · T 37.4 °C
0900 — pancreatic-drain bag now contains fresh bright red blood
Vital signs 0900 — BP 104/64 · HR 118 · RR 22 · SpO2 96% on room air
Patient — anxious, ‘I feel lightheaded’; glucose 212 mg/dL at 0800
Q1 Multiple choice
On post-op day 3 after a Whipple, which finding should the nurse treat as an emergency?
  1. A. Serous drain output that is decreasing each shift
  2. B. Sudden fresh blood in the pancreatic drain
  3. C. A blood glucose of 180 mg/dL
  4. D. Mild incisional pain controlled by the epidural
Reveal answer & rationale
Answer: B
Sudden blood in a pancreatic drain "should be treated as a potential pseudoaneurysm until ruled out" — a gastroduodenal artery pseudoaneurysm "represents a true surgical emergency" (B). Decreasing serous output (A) is expected as drains near removal. Hyperglycemia (C) is common because about 20% develop diabetes, and is reported, not an emergency. Controlled incisional pain (D) is expected.
Q2 Select all that apply
Which items belong in post-Whipple nursing care? Select all that apply.
  1. A. Follow drain amylase results on post-operative days 1 and 3
  2. B. Monitor blood glucose
  3. C. Give DVT prophylaxis as ordered
  4. D. Report inability to tolerate solid food several days after surgery
  5. E. Insist that every Whipple patient keep a nasogastric tube until discharge
  6. F. Crush enzyme capsules into milk to make them easier to take
Reveal answer & rationale
Answer: A, B, C, D
Drain amylase on days 1 and 3 screens for a pancreatic leak (A); euglycemia and DVT prophylaxis are part of the bundle (B, C); inability to tolerate a solid diet defines delayed gastric emptying (D). A nasogastric tube is used overnight and "is not mandatory" (E). CREON must not be crushed or chewed; for a patient who cannot swallow capsules, the contents go on a small amount of acidic soft food (F).
Q3 Multiple choice
A patient starting pancreatic enzyme replacement asks how to take it. Which instruction is correct?
  1. A. Take one dose each morning on an empty stomach
  2. B. Take it with meals and snacks and swallow the capsules whole
  3. C. Chew the capsules so the enzymes work faster
  4. D. Take it only when stools become oily
Reveal answer & rationale
Answer: B
The CREON label says "Take CREON during meals and snacks" and "Swallow capsules whole" (B). Once-daily fasting doses (A) miss the food the enzymes must mix with. "Do not crush or chew CREON capsules or capsule contents" (C). Enzymes are taken with food every time, not only when symptoms appear (D).
Q4 Multiple choice
A 55-year-old with no symptoms asks for a CA 19-9 test to screen for pancreatic cancer because she has type 2 diabetes. What is the best response?
  1. A. CA 19-9 is the standard screening test for people with diabetes
  2. B. Routine screening is not recommended for adults without symptoms who are not at high risk, and CA 19-9 is not specific enough to screen
  3. C. She should have a yearly CT scan because diabetes puts her at high risk
  4. D. A normal CA 19-9 rules out pancreatic cancer
Reveal answer & rationale
Answer: B
USPSTF (Grade D) recommends against screening asymptomatic adults, and people with preexisting diabetes "are included in this recommendation"; CA 19-9 has "low specificity" (B). No accurate biomarker exists for early detection (A). Diabetes alone does not place her in the high-risk group of inherited syndromes or familial pancreatic cancer (C). A normal CA 19-9 "does not preclude recurrence" and cannot rule out cancer (D).
Q5 Multiple choice
A patient with a biliary stent for pancreatic cancer develops fever, right upper abdominal pain, deepening jaundice and new confusion. What should the nurse do first?
  1. A. Give acetaminophen and recheck the temperature in 4 hours
  2. B. Escalate immediately — this suggests acute cholangitis with sepsis needing fluids, antibiotics and urgent biliary drainage
  3. C. Increase dietary fat to improve bile flow
  4. D. Document the findings as expected progression of cancer
Reveal answer & rationale
Answer: B
Fever, right upper abdominal pain and jaundice form the Charcot triad; confusion adds a Reynolds pentad feature. Acute cholangitis "is a life-threatening medical condition," "Delay in treatment can lead to septic shock," and septic patients need "immediate or emergent biliary drainage" (B). Treating the fever and waiting (A) delays care; diet changes (C) do not relieve an obstruction; calling it expected progression (D) misses a treatable emergency.

Common questions

What causes pancreatic cancer?
Common causes and risk factors include cigarette smoking — "smoking is a major risk factor for pancreatic cancer." statpearls attributes 20% of pancreatic cancers to smoking., family history / inherited genes — a first-degree relative or several second-degree relatives with pancreatic cancer or pancreatitis; brca1, brca2, palb2, atm; lynch and peutz-jeghers syndromes. "up to 10% of all pancreatic cancers are linked to inherited genetic syndromes.", chronic pancreatitis — "long-term, or chronic, pancreatitis can cause damage to the pancreatic tissue and increase your risk of cancer.", obesity — "obesity is linked to an increased risk of pancreatic cancer.", diabetes — a risk factor, and new-onset diabetes can also be a symptom, and others.
Why is painless jaundice the classic sign of pancreatic cancer?
Most tumors start in the pancreatic head, next to the common bile duct. As the tumor grows it blocks the duct, so bile backs up into the blood — jaundice, dark urine, pale stools and itching — often before there is pain. StatPearls reports it in about 50%; weight loss (about 90%) and pain (about 75%) are more common overall.
Is there a screening test for pancreatic cancer?
Not for average-risk adults. The USPSTF (2019, Grade D) recommends against screening asymptomatic adults by any method, and "There are currently no accurate, validated biomarkers for early detection." People with inherited syndromes or familial pancreatic cancer are outside that recommendation.
Will everyone need insulin after a Whipple?
No. Diabetes develops in about 20% after surgery (StatPearls), "with the rate much higher in patients who have impaired glucose tolerance preoperatively." Exocrine insufficiency is common, so many need digestive enzymes with meals.
Is this Trousseau sign?
No. Pancreatic cancer is linked to Trousseau syndrome — recurrent, migratory blood clots from a cancer-related hypercoagulable state, where heparin is the preferred anticoagulant. Trousseau sign is an unrelated finding in low calcium.
What is the outlook?
NCI: "The overall 5-year relative survival rate for all stages of pancreatic cancer is 13%" — 44% when localized, 17% when regional and 3% when distant (SEER 2015–2021). "Most pancreatic cancers are diagnosed at a later stage and cannot be cured," which is why palliative care belongs early.
