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

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

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

What is the key prehospital priority for significant GI bleeding with signs of shock?
What is the key prehospital priority for significant GI bleeding with signs of shock?
Tap to reveal answer
Airway/oxygenation and aggressive shock resuscitation. Significant bleeding compromises oxygenation and perfusion, necessitating airway protection and volume restoration to prevent organ failure.

Tap to reveal answer
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.

Which antiemetic is commonly used prehospital for nausea and vomiting (per protocol)?
Which antiemetic is commonly used prehospital for nausea and vomiting (per protocol)?
Tap to reveal answer
Ondansetron. As a serotonin receptor antagonist, it effectively controls nausea by blocking signals in the chemoreceptor trigger zone without sedating effects.

Which history finding most increases suspicion for peptic ulcer disease complications?
Which history finding most increases suspicion for peptic ulcer disease complications?
Tap to reveal answer
NSAID use or prior ulcer history. NSAIDs inhibit protective prostaglandins, while prior ulcers indicate mucosal vulnerability, both heightening risk for perforation or bleeding complications.

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.

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.
