Case 1: The Kidney Stone Crisis

Robert Chen, 55-year-old male

Score: 0/8

Question 1 of 8

Initial Presentation:

Robert arrives at the ED at 3 AM with sudden onset right flank pain that started 2 hours ago. He's pacing, unable to find a comfortable position. He rates pain 9/10, describes it as "sharp and stabbing." No fever. Urine appears pink-tinged.

VS: BP 165/95, HR 108, RR 22, Temp 98.6°F

What is your FIRST priority action?

A) Obtain stat KUB x-ray to confirm kidney stone
B) Administer ketorolac 30mg IV for pain relief
C) Insert 18G IV and send urine for urinalysis
D) Give sublingual nitroglycerin for elevated BP

Correct Answer: B

The patient is in severe pain (9/10). Pain management is the immediate priority. While the other options are important, addressing severe pain comes first. The elevated BP is likely due to pain and will improve with analgesia.

Question 2 of 8

30 minutes later:

After ketorolac, Robert's pain is 6/10. UA shows: RBC >50/hpf, WBC 5-10/hpf, no bacteria. CT scan confirms 7mm stone at right ureteropelvic junction with moderate hydronephrosis.

Current VS: BP 148/88, HR 96

What is the next priority?

A) Consult urology for immediate lithotripsy
B) Start IV fluids at 200 mL/hr
C) Give tamsulosin 0.4mg PO
D) Insert Foley catheter for accurate I&O

Correct Answer: B

IV fluids help flush the stone and prevent further kidney damage from obstruction. Tamsulosin is helpful but fluids are more urgent. Lithotripsy isn't emergent for a 7mm stone. Foley isn't necessary at this point.

Question 3 of 8

2 hours later:

Robert suddenly develops severe nausea and vomits twice. He's now having chills. Pain has increased to 10/10 despite medication.

VS: BP 92/58, HR 122, RR 26, Temp 102.8°F

What is your immediate action?

A) Give ondansetron 4mg IV for nausea
B) Increase IV fluid rate and call rapid response
C) Administer morphine 4mg IV for pain
D) Obtain blood and urine cultures

Correct Answer: B

The patient is developing septic shock (hypotension, tachycardia, fever). This requires immediate fluid resuscitation and rapid response activation. Cultures are important but hemodynamic stabilization comes first.

Question 4 of 8

Rapid Response arrives:

Two large-bore IVs placed, NS bolus running. Blood cultures drawn. Labs show: WBC 18,000, Cr 2.4 (baseline 1.0), lactate 4.2.

Urology recommends emergent nephrostomy tube placement.

Before transfer to OR, what's the priority?

A) Start broad-spectrum antibiotics immediately
B) Give vitamin K for elevated INR
C) Insert arterial line for BP monitoring
D) Obtain surgical consent from patient

Correct Answer: A

In sepsis, antibiotics should be given within 1 hour. This is time-critical. Consent is important but can be obtained en route. No mention of coagulopathy. Arterial line can wait until OR/ICU.

Question 5 of 8

Post-nephrostomy tube placement:

Robert is in ICU. Nephrostomy draining purulent urine. On norepinephrine for BP support. New labs: platelets 68,000 (was 250,000), PT/INR elevated, fibrinogen low.

What complication is developing?

A) Heparin-induced thrombocytopenia
B) Disseminated intravascular coagulation
C) Thrombotic thrombocytopenic purpura
D) Immune thrombocytopenia

Correct Answer: B

DIC is characterized by low platelets, elevated PT/INR, and low fibrinogen in the setting of severe sepsis. This is a life-threatening complication requiring immediate treatment.

Question 6 of 8

ICU Day 2:

Robert is intubated for respiratory failure. On CRRT for acute kidney injury. Nephrostomy output decreasing. Blood cultures growing E. coli.

The decreasing nephrostomy output most likely indicates:

A) Resolution of obstruction
B) Worsening kidney function
C) Tube occlusion or malposition
D) Successful stone passage

Correct Answer: C

Decreasing output from a nephrostomy tube usually indicates mechanical problems. With ongoing sepsis and kidney injury, urine production should be maintained. Tube patency must be verified immediately.

Question 7 of 8

ICU Day 3:

Nephrostomy tube flushed and patent. Robert developing purple discoloration of fingers and toes. Lactate rising despite antibiotics. Family asking about prognosis.

The purple discoloration most likely represents:

A) Peripheral cyanosis from hypoxemia
B) Purpura fulminans from DIC
C) Raynaud's phenomenon
D) Medication side effect

Correct Answer: B

Purpura fulminans is a severe manifestation of DIC causing purple discoloration and tissue necrosis. This indicates critical illness with high mortality. Family should be updated about grave prognosis.

Question 8 of 8

ICU Day 5:

Robert showing improvement. Off pressors, extubated, making urine. Stone passed spontaneously. Ready for step-down unit. Family grateful but asking how to prevent this.

Most important prevention education includes:

A) Avoid all calcium-containing foods
B) Increase fluid intake to >2.5L daily
C) Take daily vitamin C supplements
D) Limit physical activity to prevent stones

Correct Answer: B

Adequate hydration is the most important prevention strategy for kidney stones. Calcium restriction is not recommended. Vitamin C can increase stone risk. Physical activity is beneficial.

Case 2: The GI Bleed Spiral

Margaret Williams, 68-year-old female

Score: 0/10

Question 1 of 10

Initial Presentation:

Margaret presents with 3-day history of worsening epigastric pain. Takes ibuprofen 800mg TID for RA. This morning, she vomited "coffee grounds" material. Feels dizzy when standing.

VS: BP 105/70 lying, 88/58 standing, HR 98 lying, 118 standing, RR 20

What is your immediate priority?

A) Insert NG tube for gastric lavage
B) Establish 2 large-bore IVs and start NS bolus
C) Give pantoprazole 40mg IV push
D) Order stat H&H and type & crossmatch

Correct Answer: B

The patient has orthostatic hypotension indicating significant volume loss. Immediate IV access and fluid resuscitation is the priority to maintain perfusion. Labs and medications are important but come after establishing vascular access.

Question 2 of 10

30 minutes later:

Two 18G IVs placed, 1L NS infusing. Labs back: Hgb 6.8 g/dL (baseline unknown), platelets 380,000, INR 1.1. She vomits bright red blood (~200mL).

VS: BP 95/60, HR 125

What is the next critical action?

A) Transfuse 2 units PRBCs immediately
B) Start octreotide infusion
C) Insert NG tube for lavage
D) Give vitamin K 10mg IV

Correct Answer: A

With Hgb 6.8 and active bleeding, immediate transfusion is critical. Octreotide is for variceal bleeding. NG lavage doesn't stop bleeding. INR is normal, so vitamin K not indicated.

Question 3 of 10

1 hour later:

Blood transfusing. GI consulted for urgent EGD. Margaret suddenly complains of severe, sharp epigastric pain radiating to her back. Abdomen rigid.

VS: BP 82/50, HR 138, RR 28, Temp 99.8°F

This presentation suggests:

A) Worsening hemorrhage
B) Perforated peptic ulcer
C) Acute pancreatitis
D) Myocardial infarction

Correct Answer: B

Sudden severe pain with rigid abdomen indicates perforation. This is a surgical emergency requiring immediate intervention. The presentation is classic for perforated ulcer.

Question 4 of 10

STAT Response:

Surgeon at bedside. Portable CXR shows free air under diaphragm. Patient needs emergent surgery. Current Hgb 7.2 after 1 unit PRBC.

Pre-op priority is:

A) Complete the second unit of blood
B) Insert Foley catheter
C) Start broad-spectrum antibiotics
D) Obtain surgical consent

Correct Answer: C

With perforation, antibiotics must be started immediately to prevent peritonitis. Blood can continue in OR. Foley will be placed in OR. Consent important but antibiotics are time-critical.

Question 5 of 10

Post-op Day 1:

Graham patch repair completed. Margaret is intubated in ICU. Abdomen distended, no bowel sounds. NG output bilious. WBC 22,000, lactate 3.8.

The clinical picture suggests:

A) Normal post-op ileus
B) Developing peritonitis
C) Anastomotic leak
D) Small bowel obstruction

Correct Answer: B

Elevated WBC, lactate, and abdominal distension suggest peritonitis despite surgery. This requires aggressive antibiotic therapy and possible re-exploration.

Question 6 of 10

Post-op Day 2:

Margaret developing respiratory distress. CXR shows bilateral infiltrates. P/F ratio 150. Requiring increased ventilator support.

VS: BP 88/52 on norepinephrine, HR 115

This complication represents:

A) Aspiration pneumonia
B) ARDS from sepsis
C) Pulmonary embolism
D) Cardiogenic pulmonary edema

Correct Answer: B

Bilateral infiltrates with P/F ratio <200 in setting of sepsis indicates ARDS. This is a severe complication requiring lung-protective ventilation strategies.

Question 7 of 10

Post-op Day 3:

Margaret on multiple pressors, CRRT for AKI. Family meeting held. Prognosis poor. Abdomen increasingly distended with minimal NG output.

Decreasing NG output with distension indicates:

A) Resolving ileus
B) NG tube malposition
C) Abdominal compartment syndrome
D) Effective decompression

Correct Answer: C

Progressive distension despite NG suction suggests abdominal compartment syndrome, a life-threatening complication requiring decompressive laparotomy.

Question 8 of 10

Post-op Day 5:

Bladder pressure 28 mmHg (normal <12). Oliguria despite CRRT. Peak airway pressures rising. Pupils fixed and dilated.

Fixed dilated pupils indicate:

A) Medication effect from sedation
B) Increased intracranial pressure
C) Hypoglycemia
D) Electrolyte imbalance

Correct Answer: B

Fixed dilated pupils suggest brain herniation from increased ICP, likely due to severe hypoxia and hypotension. This indicates grave prognosis.

Question 9 of 10

Family Meeting:

Neurology confirms brain death. Family struggling with decision. They ask "How did a stomach problem lead to this?"

Best explanation includes:

A) "The bleeding was too severe to treat"
B) "Perforation led to infection, organ failure, and brain injury"
C) "This was an unavoidable complication"
D) "The surgery was unsuccessful"

Correct Answer: B

Honest, clear explanation of the cascade: perforation → peritonitis → sepsis → multi-organ failure → brain death helps family understand while maintaining compassion.

Question 10 of 10

Learning Point:

Margaret's case started with chronic NSAID use for RA. What's the most important prevention strategy for NSAID-related GI complications?

Best prevention approach:

A) Take NSAIDs with food
B) Use lowest effective dose + PPI prophylaxis
C) Switch to acetaminophen only
D) Take NSAIDs only when pain severe

Correct Answer: B

Evidence supports using lowest effective NSAID dose with PPI prophylaxis in high-risk patients. Food doesn't prevent ulcers. Acetaminophen ineffective for RA. PRN use doesn't reduce risk.
