Question 1 of 10

A 46-year-old patient with a history of heavy alcohol use reports severe pain in the upper abdomen that radiates straight through to the back and has been constant for 3 hours. The pain began after eating dinner, and the patient describes several episodes of vomiting. The vital signs are BP 138/86, P 108, R 20, SpO₂ 97%. The abdomen is tender across both upper quadrants without rigidity or guarding. A 12-lead ECG shows a normal sinus rhythm without ST-segment changes. Which of the following conditions should the paramedic most strongly suspect?

Show the answer and rationale

Correct answer · Acute pancreatitis

This patient has acute pancreatitis. The patient has a history of heavy alcohol use, and the pain started after dinner. The pain is severe, has been constant for 3 hours, and radiates from the upper abdomen straight through to the back. The patient has also vomited several times. Pancreatitis causes steady upper abdominal pain that radiates to the back. Alcohol use often triggers pancreatitis, and eating makes the pain worse. The 12-lead ECG is normal, and the abdomen is tender across both upper quadrants without rigidity or guarding. Those findings fit pancreatitis better than a heart attack, an ulcer, or mesenteric ischemia.

Why the others are wrong

Inferior myocardial infarction: An inferior myocardial infarction can show up as upper abdominal pain with vomiting, and those are real cardiac warning signs. This patient's 12-lead ECG shows no ST-segment changes. Nothing on the ECG supports an inferior MI.

Perforated peptic ulcer: A perforated ulcer irritates the lining of the abdomen and makes the abdomen rigid and board-like. This abdomen is tender, but there is no rigidity and no guarding.

Acute mesenteric ischemia: Mesenteric ischemia is known for pain that is out of proportion to the exam. In mesenteric ischemia the abdomen stays soft and only mildly tender even though the pain is severe. This patient's abdomen is tender across both upper quadrants, so the exam matches the pain.

Question 2 of 10

A 58-year-old patient with a history of cirrhosis is found in the bathroom after passing a large volume of bright red blood per rectum twice in the last hour. The skin is cool and pale and the patient is anxious. The vital signs are BP 96/62, P 124, R 22, and SpO₂ 95% on room air. Which conclusion about the bleeding source do these findings support?

Show the answer and rationale

Correct answer · A brisk upper source can move fast enough to arrive at the rectum still red

A fast upper GI bleed can reach the rectum while the blood is still bright red. This patient has cirrhosis and has passed a large volume of bright red blood twice in the last hour. Blood turns black and tarry when acid and enzymes in the gut have hours to work on it. Bright red blood usually means a source low in the tract, where the blood had no time to change. An upper source that bleeds fast enough pushes the blood through before it can be digested, so it still comes out red. A patient with cirrhosis can have varices, and a variceal bleed is exactly this kind of fast upper bleed. The pulse of 124 and the cool, pale skin tell you the bleeding is fast. Read the color together with how fast the patient is bleeding and the history of liver disease. Those three together tell you much more about the source than the color alone.

Why the others are wrong

A lower source such as diverticular bleeding or hemorrhoids is the origin: Bright red blood per rectum does come from a lower source like diverticular bleeding or hemorrhoids most of the time, but not every time. This patient has cirrhosis, a pulse of 124, and cool, pale skin. A fast variceal bleed gives you the same red color. Calling this a hemorrhoid or diverticular bleed sets your urgency far too low.

Bright red blood per rectum excludes esophageal varices as the source: Dark blood does point to an upper source. The rule does not work in reverse, so red blood cannot rule out an upper source. A variceal bleed that is fast enough comes out red. Stool color can raise or lower your suspicion of a source, but color can never rule a source out.

Blood this red has spent less than ten minutes inside the gut: Faster bleeding does mean the blood spent less time in the gut. The color cannot give you a time that precise. Nothing about the color tells you the bleeding started minutes ago instead of an hour ago. If you build a time estimate on the color, you will underestimate how much blood this patient has already lost.

Question 3 of 10

A 61-year-old patient with long-standing cirrhosis vomits a large volume of bright red blood. The skin is pale and diaphoretic, the abdomen is distended, and the patient answers questions slowly. The vital signs are BP 88/54, P 132, R 26, and SpO₂ 93% on room air. Beyond the high pressure inside the bleeding vessels, which feature of this patient's liver disease makes the bleeding hardest to control?

Show the answer and rationale

Correct answer · The scarred liver can no longer manufacture clotting factors

This patient has a variceal bleed from cirrhosis, and the scarred liver can no longer make clotting factors. The patient vomited a large amount of bright red blood, the pressure is 88/54, and the pulse is 132. Cirrhosis causes the bleeding and also makes the bleeding hard to stop. First, scar tissue blocks blood flow through the portal system. Pressure backs up into thin-walled veins at the bottom of the esophagus. Those veins, called varices, bulge and eventually tear. The tear explains the large volume of blood. Second, the liver is where clotting factors are made. A liver scarred enough to raise portal pressure has usually stopped making clotting factors. That's why a variceal bleed in cirrhosis is so hard to stop. In the field, focus on airway control, volume, and keeping the patient warm. Transport fast to a hospital that can stop the bleeding directly.

Why the others are wrong

Bile backing into the bloodstream is thinning the circulating blood: Jaundice is the most visible sign of liver failure, so bile in the blood seems like it should matter. Bile pigment in the plasma does not thin the blood or change clotting. What fails is the liver making the proteins that clotting needs.

The distended abdomen is compressing the portal vein even further: The abdomen is distended, and pressure on a vein sounds like it would raise portal pressure further. The fluid in the belly, called ascites, is a result of the high portal pressure. Ascites does not drive the pressure up on its own. Squeezing the vein from outside is not what keeps this bleed going.

An enlarged spleen is filtering out red cells faster than they are made: The spleen does enlarge with high portal pressure, and the spleen does remove blood cells. Losing red cells lowers how much oxygen the blood can carry, but losing red cells does nothing to forming a clot at the tear. The question asks what makes the bleeding hard to stop.

Question 4 of 10

A 41-year-old patient reports steady left lower quadrant pain that has built over two days. The abdomen has been exposed and inspected, and the patient is lying still with the knees drawn up. The vital signs are BP 128/80, P 96, R 18, and SpO₂ 99% on room air. The paramedic is ready to palpate. Where should palpation begin?

Show the answer and rationale

Correct answer · In a quadrant away from the pain, saving the painful one for last

Start palpating in a quadrant away from the pain and save the painful left lower quadrant for last. Once you press on the painful spot, the patient tenses up the whole abdomen. After that, you cannot get a good read on the other quadrants. You only get one clean pass across all four quadrants. Starting where it hurts uses up that pass right away. Begin in a quadrant the patient has not complained about. Note what is soft and what is not, then work your way around so the left lower quadrant comes last. You also never press deeply on a pulsating mass. Pressing there can do more harm than the finding is worth.

Why the others are wrong

At the umbilicus, working outward toward each quadrant in turn: Starting at the umbilicus and working outward sounds organized. The problem is the starting point. Working outward from the middle leaves the order of the quadrants to chance, so the painful quadrant may come second.

Across the upper quadrants only, leaving the lower half alone: Staying out of the lower half avoids the painful area, so the patient never tenses up. Skipping half the abdomen means you miss half the findings. You need to examine all four quadrants and save the painful one for last.

In the left lower quadrant, to confirm the reported pain first: The patient already told you the pain is in the left lower quadrant, so you do not need to confirm it first. Pressing there first makes the whole abdomen tense. The three quadrants you have not checked yet become impossible to read.

Question 5 of 10

A 49-year-old patient with a history of heavy alcohol use reports severe steady epigastric pain that bores through to the back, with repeated vomiting. The abdomen is soft, with no guarding and no rebound tenderness. The vital signs are BP 108/70, P 116, R 22, and SpO₂ 96% on room air. Why does the soft abdomen fail to reassure the paramedic here?

Show the answer and rationale

Correct answer · The pancreas lies behind the peritoneum, which stays uninflamed early

This patient most likely has pancreatitis. The pain is severe, steady, and epigastric, and it bores through to the back. The patient drinks heavily and keeps vomiting, and the pulse is 116. The pancreas sits behind the peritoneum, the lining of the abdomen. Guarding and rebound tenderness come from an irritated peritoneum. Early on, the irritation from the pancreas has not reached that lining yet. That's why the pain can be severe while the abdomen stays soft. The kidneys sit behind the peritoneum too, and kidney problems can also hurt badly with a soft abdomen. A soft abdomen does not rule out a sick patient. When the belly exam is quiet, go by the pain pattern, the history, and the vital signs. Pancreatitis pulls a lot of fluid out of the blood vessels, so plan on IV fluid for this patient.

Why the others are wrong

Vomiting empties the stomach and temporarily softens the abdominal wall: Vomiting does empty the stomach, and an empty stomach is less distended. Guarding comes from an irritated peritoneum, not from a full stomach.

Guarding takes at least 12 hours to develop in any abdominal process: There is no set number of hours before guarding shows up. A perforated ulcer causes sudden severe pain and a rigid abdomen. This abdomen is soft because of where the pancreas sits, not because of how long the pain has lasted.

Alcohol dulls the abdominal reflexes that produce guarding and rebound: This patient drinks heavily, and an intoxicated patient may not be able to tell you something is wrong. This patient is reporting severe pain, so the alcohol is not hiding anything. The location of the pancreas explains the soft abdomen without needing the alcohol.

Question 6 of 10

A 72-year-old patient with two prior abdominal surgeries reports 18 hours of pain that grips and then eases, repeated vomiting, and no stool or gas passed since yesterday morning. The abdomen is distended and tympanic. The vital signs are BP 122/78, P 104, R 20, and SpO₂ 97% on room air. Which condition does this pattern describe?

Show the answer and rationale

Correct answer · Bowel obstruction

This is a bowel obstruction. The pain grips and then eases, the patient keeps vomiting, and no stool or gas has passed since yesterday morning. The abdomen is distended and tympanic. The bowel is a hollow tube, and something is blocking it. The bowel squeezes hard against the blockage and then rests. That's why the pain comes in waves instead of staying constant. Everything above the blockage backs up, so the patient vomits. Gas and stool cannot get past, so the abdomen swells and sounds hollow when you tap it. The two prior abdominal surgeries matter here. Scar tissue from surgery, called adhesions, is the most common cause of a bowel obstruction in adults.

Why the others are wrong

Acute pancreatitis: Pancreatitis does cause severe pain and vomiting. Pancreatitis pain is steady and bores through to the back instead of gripping and easing. Pancreatitis also does not stop stool and gas from passing.

Perforated peptic ulcer: A perforated ulcer is the emergency you cannot afford to miss. A perforation starts suddenly, the abdomen turns rigid and board-like, and the patient will not move. This abdomen is distended and tympanic, and the pain comes and goes.

Acute diverticulitis: Diverticulitis is common at 72 and also causes belly pain and changes in bowel habits. Diverticulitis pain usually sits in the left lower quadrant, with tenderness and fever. Diverticulitis does not usually block gas from passing.

Question 7 of 10

A 45-year-old patient has vomited eight times in four hours and cannot keep water down. Vascular access has been established and an antiemetic is ordered. The vital signs are BP 112/72, P 108, R 18, and SpO₂ 98% on room air. By which route should the antiemetic be given?

Show the answer and rationale

Correct answer · Intravenously, since nothing swallowed is going to stay down

Give the antiemetic intravenously. This patient has vomited eight times in four hours and cannot keep water down. A drug the patient vomits back up has not been given. The same goes for fluid, so the fluid goes through the IV line instead of by mouth. Vascular access is already in place, so use the line. In a patient who keeps vomiting, get IV access early, before the veins get harder to find. Once the vomiting is under control, reassess the patient. Vomiting eight times in four hours is a symptom of something nobody has diagnosed yet.

Why the others are wrong

Intramuscularly, since the intravenous route acts too quickly here: The intramuscular route also bypasses the gut. Acting quickly is not a reason to avoid the IV route in a patient who is sick right now. With a line already in place, the IV route is faster and more reliable than an intramuscular shot.

Orally, since the oral route is preferred whenever it is available: The oral route is preferred in a lot of situations because it avoids a needle. That preference only holds when the gut is working. This patient cannot keep water down, so an oral drug probably never reaches the blood.

Subcutaneously, since a slower uptake is gentler on an irritated gut: A slower uptake sounds easier on an upset stomach. The gut does not absorb a subcutaneous drug, so being gentle on the gut does not apply here. With a line already in, a slower route only delays relief.

Question 8 of 10

A 63-year-old patient with a known gastrointestinal bleed is pale and confused, and transport time is 30 minutes. The vital signs are BP 78/50, P 130, R 26, and SpO₂ 94% on room air. What fluid plan fits this patient?

Show the answer and rationale

Correct answer · Isotonic crystalloid titrated to a perfusion endpoint, reassessed after each bolus

Give isotonic crystalloid in boluses titrated to perfusion, and reassess after each bolus. This patient is pale and confused with a pressure of 78/50, so the patient needs volume. Too much fluid dilutes the clotting factors the patient is counting on to seal the bleed. Judge each bolus by perfusion. After every bolus, check the mental status, the skin, and whether you can feel a pulse. If you aim for a normal systolic pressure, you will give too much fluid, thin the blood, and break up clots that had formed. If you give nothing, a confused, hypotensive patient keeps getting worse.

Why the others are wrong

Isotonic crystalloid run wide open until the systolic pressure reaches 120: A normal systolic pressure is what you want this patient to have eventually. Crystalloid carries no clotting factors and dilutes the ones the patient has left. Pushing the pressure up to 120 can restart the bleeding or make it worse.

Isotonic crystalloid as a single 2 L bolus given as fast as the line allows: A single 2 L bolus is fast and easy to order. A large, fixed volume with no reassessment is how the clotting factors get diluted. A single bolus also skips the perfusion check that should decide the next amount of fluid.

Isotonic crystalloid at a keep-open rate until the hospital decides: A keep-open rate avoids diluting the blood. This patient is confused and hypotensive, which is decompensated shock. Holding back fluid at this point trades one harm for a worse one.

Question 9 of 10

A 46-year-old patient has severe epigastric pain that bores through to the back, with repeated vomiting for a day. The abdomen is distended and diffusely tender. The vital signs are BP 88/56, P 126, R 24, and SpO₂ 95% on room air. What best explains the low blood pressure?

Show the answer and rationale

Correct answer · Fluid shifting out of the vascular space into the surrounding tissue

This patient has pancreatitis, and the low blood pressure comes from fluid shifting out of the blood vessels. The pain is severe, in the epigastric area, and bores through to the back. That pain pattern points to the pancreas. The inflamed pancreas leaks fluid out of the vessels into the tissue around it. This is called third spacing. The fluid is still inside the patient, but the fluid is no longer in the vessels where it can hold up the pressure. That's why the pressure is 88/56 and the pulse is 126 with no blood loss you can see. Give these patients a lot of fluid instead of searching for a source of bleeding.

Why the others are wrong

A vagal response to the severity of the abdominal pain: A vagal response can drop the blood pressure when pain is severe, and a vagal response also slows the pulse. This patient's pulse is 126.

Ongoing bleeding into the gastrointestinal tract from an ulcer: A bleeding ulcer fits a low pressure with a fast pulse, because blood is leaving the body. Nothing in this question describes blood being lost. The fluid left the vessels, but it never left the patient.

Sepsis from an infected gallbladder blocking the duct: An infected gallbladder sits right next to this area and also causes epigastric pain. Nothing in the question mentions a fever or an infection. The fluid shift already explains the low pressure.

Question 10 of 10

A 54-year-old patient with a history of cirrhosis reports vomiting a large amount of bright red blood. The patient is confused, and emesis is pooling in the oropharynx. The vital signs are BP 82/50, P 128, R 24, SpO₂ 90%. What is the most appropriate initial action?

Show the answer and rationale

Correct answer · Suction the airway and prepare for definitive airway control

This patient is most likely bleeding from esophageal varices. A patient with cirrhosis who vomits bright red blood is usually bleeding from these swollen veins in the esophagus. Cirrhosis raises the pressure in these veins, which is called portal hypertension. Liver disease also keeps the blood from clotting well. High pressure plus poor clotting makes this bleeding fast and heavy. This patient is confused and has vomit pooling in the oropharynx. The airway is already at risk for aspiration. Suction the airway, position the patient, and get ready for definitive airway control. A patient who aspirates blood cannot oxygenate, no matter how much fluid you give afterward. An airway problem kills faster than the bleeding.

Why the others are wrong

Establish two large-bore intravenous lines and begin crystalloid: Two large-bore IVs and crystalloid are the right treatment for this patient. IV access comes after the airway. Starting IVs first leaves blood pooling in the airway, and the patient can aspirate while you work on a line.

Administer tranexamic acid per protocol: Tranexamic acid is above the national Paramedic scope of practice, so giving tranexamic acid is not a field decision you make here. Even setting scope aside, a medication does nothing to clear the blood already pooling in the oropharynx.

Apply high-flow oxygen by NRB and reassess: An NRB cannot get oxygen past an airway partly blocked by pooling vomit. An NRB also does nothing about the aspiration risk. The airway has to be cleared and protected, not just given oxygen.
