9 free EMT practice questions: Abdominal, GI, GU & Renal Disorders

A history of chronic nonsteroidal anti-inflammatory drug use: Chronic nonsteroidal anti-inflammatory drug use is the best clue in the question for why this happened. These drugs wear down the stomach's protective lining and are a leading cause of peptic ulcers and perforation. A risk factor raises suspicion, but it does not confirm anything. Most chronic users have gastritis at worst and never perforate.

The sudden rather than gradual onset of the pain: Sudden onset does point toward a perforation or a blood vessel problem over inflammation that builds over hours. Sudden onset is not specific enough by itself. Kidney stone pain, gallbladder pain, and gastroenteritis can all start suddenly, and none of them is this kind of surgical emergency. The sudden start only tells you the problem began fast, while the rigidity shows the peritoneum is already involved.

A heart rate of 112/min without a drop in blood pressure: A pulse of 112 shows the body is compensating for pain, for fluid shifting into the inflamed abdomen, or for early volume loss. The fast pulse is a good reason to keep this a high-priority transport. A fast pulse is not specific, though. The blood pressure is still 106/70, so the pulse is the only vital sign that is off. A fast pulse can come from pain alone. The heart rate tells you how far along the problem has gotten, not that the peritoneum is involved.

The patient has a simple hernia that requires only outpatient surgical referral: A simple hernia is a soft bulge that comes out with straining, goes back in, and causes no symptoms. Outpatient referral to a surgeon is fine for a simple hernia. This patient probably had that kind of hernia before today. Today the bulge is rigid and severely tender, the patient has vomited, and the abdomen is distended. The hernia is now incarcerated, not simple.

The hernia is irreducible but not dangerous and can wait for elective surgery: Option C is right that the hernia is irreducible, meaning the bulge will not push back in. The ring trapping the loop of bowel is also cutting off the bowel's blood supply, so this hernia is dangerous. Severe tenderness, nausea, vomiting, and a distended abdomen point to strangulation. A strangulated hernia cannot wait for an elective surgery date.

The symptoms indicate acute appendicitis, not hernia-related pathology: Appendicitis causes pain around the belly button that moves to the right lower quadrant. Appendicitis also brings rebound tenderness, a low fever, loss of appetite, nausea, and vomiting. This patient does have nausea and vomiting. The pain is at a rigid, tender bulge in the groin of a patient with a known hernia. The groin bulge points to the hernia, not the appendix.

Hematemesis: vomiting blood. The blood can be bright red, or it can look like coffee grounds once it is partly digested. This patient is describing stool, not vomit.

Hemoptysis: coughing up blood or blood-streaked sputum from the lungs or airway. Hemoptysis comes from the respiratory system, and this patient's complaint is tarry stool.

Hematuria: Blood in the urine is hematuria. Hematuria turns the urine pink, red, or brown. This patient is describing a stool problem, not a urine problem.

This is a non-emergent condition; advise the patient to drink fluids and follow up with his physician: Fluids and a doctor visit fit the slow, long-term side of prostate trouble. Those patients urinate often, get up at night to urinate, and have a weak stream, but they still empty the bladder. This patient is making urine and cannot pass any of it. More fluid only adds volume to a bladder that is already distended. An office visit takes days, and this blockage has already gone 8 hours.

Have the patient try to void once more, and transport only if that attempt fails: Trying to urinate one more time is what anyone would do at home. This patient has already been trying for 8 hours. An enlarged prostate squeezing the urethra is a mechanical blockage, and pushing harder does not open it. Waiting on another try keeps the bladder under pressure longer and keeps backing urine up toward the kidneys.

Apply firm manual pressure to the suprapubic region to assist in bladder emptying: Pressing on the bladder cannot push urine past a blockage in the urethra at the prostate. The urine has nowhere to go. Pushing hard on a bladder that has been filling for 8 hours adds pain and can rupture the bladder. A ruptured bladder turns a fixable blockage into a surgical emergency.

Apply ice packs and elevate the affected area to reduce swelling and pain: Ice and elevation are first aid for swelling from an injury, like a bruise or a sprain. This erection did not come from an injury. Priapism is blood trapped in the erectile tissue, and it may need surgery. Only the hospital can do that, so urgent transport to the ED is the action this patient needs.

Attempt gentle manual manipulation or massage to encourage flaccidity: Massage or manual manipulation is not a treatment for priapism. Priapism may need surgery, and only the hospital can do that. Rubbing an organ that is already this painful adds injury and delays the trip to the ED.

Advise the patient that this will likely resolve spontaneously and recommend outpatient follow-up: A normal erection from sexual stimulation goes away on its own. This erection has lasted 3 hours with no sexual trigger, it is painful, and the patient is diaphoretic and distressed. Priapism may need surgery, and outpatient follow-up delays the hospital care this patient needs now.

Recognize signs of urinary tract infection only; provide comfort care and arrange routine transport for urinalysis: Dysuria, frequency, and urgency over two days do fit a simple UTI. This patient also has a blood pressure far below baseline and new confusion. Those show the infection has already spread past the bladder into the bloodstream. Routine transport for a urinalysis treats the bladder symptoms and misses the life threat.

Recognize that confusion is normal in elderly patients; reassure the family and arrange transport at the patient's convenience: Some elderly patients do have long term confusion as their normal. This patient was clear enough to describe dysuria and urgency over the past 2 days. Now the patient is oriented to place only. A change like this is acute, and acute confusion in an infected patient is a red flag for sepsis. Reassuring the family only delays care.

Administer high-flow oxygen only if SpO2 drops below 90%, and transport to the nearest facility: Holding oxygen until the SpO2 drops below 90% treats the pulse oximeter reading instead of the patient. The respiratory rate is 24, and sepsis is already hurting blood flow to the tissues. Oxygen delivery to the tissues is already poor right now, even with a reading of 96%.

Blood loss inside the abdomen is causing shock: A fast respiratory rate can be an early sign of hidden bleeding. Bleeding inside the abdomen comes with a fast pulse and signs like pallor and sweating. This patient has a pulse of 76, a blood pressure of 124/78, and warm, dry skin.

A severe infection is causing septic shock: An infection in the abdomen can lead to septic shock and fast breathing. This patient's temperature is 98.8°F, and the pulse and blood pressure are normal. None of those findings fit septic shock.

Fluid is backing up into the lungs: Fluid backing up into the lungs, like with pulmonary edema, causes fast, shallow breathing. This patient's breath sounds are clear in all fields and the SpO₂ is 97% on room air. The lungs themselves are not the problem.

Burning with urination: the classic bladder symptom. Burning would be the right answer if the question asked what points to a bladder infection in the first place. Urine from an infected kidney still passes through the irritated bladder, so the burning keeps going after the infection moves up. The burning was also there for all three days, before the patient got sicker, and the question asks what changed.

Increased urinary frequency: Increased frequency tells you the bladder wall is irritated and cannot hold a normal amount of urine. Frequency would answer a question about which symptom points to the bladder. Frequency stays when the infection climbs, so it shows up in both cystitis and pyelonephritis. Frequency does not tell you which infection this is.

A 3-day symptom duration: The 3-day duration is worth documenting, because it tells the hospital how long the infection had to move up. Duration alone never tells you which organ is involved. A bladder infection can last a week and stay in the bladder, and pyelonephritis can develop in less than a day. Time is a risk factor, and the question asks for a finding.

The pain spread along a dermatome as an infection entered the bloodstream: Some pain does follow a dermatome, a band of skin served by one nerve. Shingles pain follows a dermatome this way. This patient's pain sharpened because a local structure, the parietal peritoneum, became irritated. An infection in the bloodstream makes a patient sick all over. A bloodstream infection does not focus pain into one quadrant.

Referred pain traveled along shared nerve pathways to a distant, more sensitive area: Referred pain is felt far from the organ, because the organ and the distant spot share nerve pathways. Gallbladder pain felt in the shoulder is referred pain. This patient's pain did not move somewhere distant. The pain sharpened right at the inflamed structure, in the right lower quadrant, and the patient now guards against movement.

The abdominal muscles fatigued, letting the underlying organ pain be felt directly: Tired abdominal muscles do not change how pain signals travel. Nothing about muscle fatigue would make pain sharper or move pain to one spot. The change here came from the nerves of the parietal peritoneum, not from the muscles.
