Gastrointestinal and Abdominal Emergencies - NREMT Paramedic Level

1. Identify the likely cause: cirrhosis history plus hematemesis and hypotension.

   Esophageal variceal hemorrhage. Cirrhosis leads to portal hypertension and varices, which can rupture, causing massive upper GI bleeding and subsequent hemodynamic instability.

2. What is the most appropriate initial approach to abdominal pain in the unstable patient?

   Treat for shock and rapid transport. Unstable patients require immediate stabilization of vital signs and expedited transfer to definitive care to address underlying life-threatening causes.

3. What is the primary life threat you must suspect with abdominal pain plus hypotension?

   Hemorrhagic shock from intra-abdominal bleeding. Hypotension accompanying abdominal pain signals potential internal hemorrhage, posing an immediate threat to perfusion and requiring prompt intervention.

4. Identify the most appropriate positioning for a patient with active vomiting and intact airway reflexes.

   Left lateral recumbent (recovery position). This position facilitates drainage of vomit and reduces aspiration risk while maintaining airway patency in conscious patients.

5. Which abdominal assessment finding most strongly suggests peritonitis?

   Rebound tenderness with involuntary guarding. These physical signs reflect peritoneal inflammation, indicating irritation from infection, perforation, or fluid leakage into the abdominal cavity.

6. Which abdominal emergency is most associated with sudden tearing pain radiating to the back in older patients?

   Abdominal aortic aneurysm. Aneurysmal rupture in older adults with risk factors like hypertension produces this pain pattern from dissection and retroperitoneal involvement.

7. What term describes vomiting of blood, often indicating an upper GI bleed?

   Hematemesis. Vomiting blood typically originates from sources above the ligament of Treitz, distinguishing it as a hallmark of upper gastrointestinal hemorrhage.

8. What diagnosis should you suspect with epigastric pain radiating to the back plus vomiting?

   Acute pancreatitis. These symptoms arise from pancreatic inflammation, causing enzyme release that irritates surrounding tissues and triggers nausea with back radiation.

9. Which antiemetic is commonly used prehospital for nausea and vomiting (per protocol)?

   Ondansetron. As a serotonin receptor antagonist, it effectively controls nausea by blocking signals in the chemoreceptor trigger zone without sedating effects.

10. What is the most concerning complication of persistent vomiting in an infant or child?

    Dehydration leading to shock. Infants and children have higher fluid requirements and lose volume rapidly, making dehydration from vomiting a pathway to hypovolemic shock.

11. What is the preferred fluid for initial volume resuscitation in suspected hemorrhagic shock?

    Isotonic crystalloid (normal saline or lactated Ringer's). These solutions restore intravascular volume effectively in hemorrhage, maintaining osmotic balance without causing fluid shifts or electrolyte imbalances.

12. Which quadrant is most associated with acute cholecystitis pain and tenderness?

    Right upper quadrant. The gallbladder is located in this quadrant, where inflammation from gallstones or infection typically manifests as localized pain and tenderness.

13. Which history finding most increases suspicion for peptic ulcer disease complications?

    NSAID use or prior ulcer history. NSAIDs inhibit protective prostaglandins, while prior ulcers indicate mucosal vulnerability, both heightening risk for perforation or bleeding complications.

14. Which quadrant is most associated with diverticulitis pain and tenderness?

    Left lower quadrant. Diverticula are commonly found in the sigmoid colon, leading to inflammation and pain in this quadrant when infected or perforated.

15. What is the key prehospital priority for significant GI bleeding with signs of shock?

    Airway/oxygenation and aggressive shock resuscitation. Significant bleeding compromises oxygenation and perfusion, necessitating airway protection and volume restoration to prevent organ failure.

16. Identify the likely diagnosis: sudden severe abdominal pain with rigid abdomen and rebound tenderness.

    Perforated viscus with peritonitis. Sudden perforation allows gastrointestinal contents to spill into the peritoneum, causing intense inflammation, rigidity, and pain on rebound.

17. Which condition should you suspect with severe abdominal pain out of proportion to exam findings?

    Acute mesenteric ischemia. Intestinal blood supply occlusion causes intense pain from ischemia, yet physical exam may appear mild due to lack of peritoneal involvement initially.

18. Which finding most strongly suggests bowel obstruction rather than gastroenteritis?

    Absent flatus with abdominal distension. Obstruction prevents gas passage, leading to accumulation and distension, unlike gastroenteritis which typically allows some flatus despite inflammation.

19. Which finding most suggests a lower GI bleed rather than an upper GI bleed?

    Hematochezia (bright red blood per rectum). Bright red rectal blood usually indicates a distal source below the ligament of Treitz, as it lacks time for digestion and darkening.

20. Which analgesic is commonly used for severe abdominal pain when hypotension is not present (per protocol)?

    Fentanyl. This opioid provides potent pain relief via mu-receptor agonism, suitable for normotensive patients per protocols to avoid further hemodynamic compromise.

21. What is the classic appearance of upper GI bleeding due to digested blood?

    Melena (black, tarry stool). Digestion of blood in the upper GI tract produces this characteristic stool due to oxidation and bacterial breakdown during transit.

22. Which quadrant is most associated with appendicitis pain after migration from periumbilical area?

    Right lower quadrant. Appendiceal inflammation often starts periumbilically but localizes here due to the appendix's anatomical position in the lower right abdomen.

23. Which immediate action is best: abdominal pain, syncope, hypotension, pulsatile abdominal mass?

    Rapid transport with shock management; suspect ruptured AAA. These signs indicate possible aneurysm rupture, requiring immediate transport and shock treatment to stabilize until surgical intervention.
