Internal Medicine · Emergency Medicine and Clinical ImmunologySample Question #1
Recognizing First-Line Treatment for Anaphylaxis with Hypotension
Learning Objective: Recognizing first-line emergency treatment in acute anaphylaxis with cardiovascular compromise
Clinical Vignette
A 24-year-old woman develops generalized urticaria, wheezing, and dizziness shortly after receiving an injectable antibiotic. Her blood pressure is 78/46 mmHg. Which is the most appropriate immediate treatment?
Multiple-Choice Options
AIntravenous hydrocortisone infusion
BInhaled salbutamol nebulization therapy
CIntramuscular epinephrine injection
Correct
DOral cetirizine antihistamine solution
Why Option C is Correct
The rapid onset of skin symptoms, bronchospasm, and severe hypotension after exposure to a likely trigger indicates anaphylaxis with cardiovascular compromise. Intramuscular epinephrine is the first-line treatment because it supports blood pressure through alpha-adrenergic vasoconstriction and helps relieve bronchospasm through beta-adrenergic effects. Emergency assessment, appropriate positioning, oxygen and intravenous fluids when indicated, and ongoing monitoring are also important.
Why the Other Options are Incorrect
Option A (Intravenous hydrocortisone infusion): Corticosteroids are not first-line emergency treatment for anaphylaxis and must not delay epinephrine. Their onset of action requires 4 to 6 hours, rendering them ineffective for acute hemodynamic collapse.
Option B (Inhaled salbutamol nebulization therapy): It can help bronchospasm but does not adequately address the systemic cardiovascular collapse or shock in anaphylaxis.
Option D (Oral cetirizine antihistamine solution): An oral antihistamine may help relieve cutaneous urticaria but has a slow onset and cannot treat life-threatening airway compromise or distributive shock.
Exam Trap
Do not mistake improvement of one symptom for treatment of the whole emergency. A bronchodilator may improve wheezing, but it does not replace epinephrine in anaphylaxis with hypotension.
Key Takeaway
In suspected anaphylaxis, administer intramuscular epinephrine promptly. Adjunctive treatments must not delay it.

Identifying the Immediate Priority for Severe Hyperkalemia with ECG Changes
Learning Objective: Identifying the immediate cardiac membrane stabilization priority in severe hyperkalemia with ECG changes
Clinical Vignette
A 63-year-old man with chronic kidney disease presents with generalized weakness. His ECG shows tall, peaked T waves and widening of the QRS complexes. Laboratory testing confirms severe hyperkalemia. Which treatment should be administered immediately to reduce the risk of a fatal arrhythmia?
Multiple-Choice Options
AOral sodium bicarbonate solution
BDietary potassium restriction protocol
COral sodium polystyrene sulfonate resin
DIntravenous calcium gluconate administration
Correct
Why Option D is Correct
Severe hyperkalemia accompanied by ECG changes can cause life-threatening cardiac conduction disturbances. Intravenous calcium gluconate stabilizes the cardiac membrane and reduces the immediate risk of hyperkalemia-related arrhythmias. It does not remove potassium from the body or lower the serum potassium concentration, so additional potassium-lowering treatment and monitoring are required.
Why the Other Options are Incorrect
Option A (Oral sodium bicarbonate solution): It is not an appropriate immediate substitute for cardiac membrane stabilization. Bicarbonate has a role in selected situations, particularly when significant metabolic acidosis is present.
Option B (Dietary potassium restriction protocol): This contributes to long-term chronic outpatient maintenance but cannot treat an acute hyperkalemic cardiac emergency.
Option C (Oral sodium polystyrene sulfonate resin): A gastrointestinal cation exchange resin has a delayed onset of several hours and does not provide immediate myocardial membrane stabilization.
Exam Trap
Do not confuse stabilizing the myocardium with removing potassium. Calcium protects the heart temporarily; it does not correct the hyperkalemia itself.
Key Takeaway
When hyperkalemia produces dangerous ECG changes, prioritize immediate cardiac membrane stabilization while initiating measures to lower potassium and arranging appropriate monitoring.

Internal Medicine · Infectious Diseases and Regional ZoonosesSample Question #3
Selecting First-Line Dual Antimicrobial Regimen for Acute Brucellosis
Learning Objective: Selecting first-line dual antimicrobial therapy for regional zoonotic Brucellosis with musculoskeletal involvement
Clinical Vignette
A 32-year-old man presents to an outpatient clinic with a 4-week history of undulant low-grade fever, night sweats, fatigue, and severe lower back pain. He reports frequently consuming unpasteurized raw camel milk from a livestock farm. On physical examination, there is point tenderness over the L4-L5 lumbar vertebrae and sacroiliac joint. Serum agglutination test (SAT) is positive at a titer of 1:320. Which of the following is the most appropriate antimicrobial regimen?
Multiple-Choice Options
AOral Ciprofloxacin 500 mg twice daily plus oral Doxycycline 100 mg twice daily for 6 weeks
BOral Doxycycline 100 mg twice daily plus oral Rifampin 600 mg once daily for 6 weeks
Correct
CIntravenous Ceftriaxone 2 g once daily plus oral Azithromycin 500 mg once daily for 6 weeks
DOral Amoxicillin-Clavulanate 1 g twice daily plus oral Ciprofloxacin 500 mg twice daily for 6 weeks
Why Option B is Correct
First-line therapy for uncomplicated Brucellosis is dual therapy with Doxycycline and Rifampin for at least 6 weeks to prevent relapse and osteoarticular complications. Brucella species are facultative intracellular pathogens that survive within reticuloendothelial macrophages. Monotherapy is associated with unacceptably high relapse rates (>30%) and fails to eradicate deep tissue sequestration in bone.
Why the Other Options are Incorrect
Option A (Oral Ciprofloxacin 500 mg twice daily plus oral Doxycycline 100 mg twice daily for 6 weeks): Fluoroquinolone monotherapy produces rapid initial clinical response but results in severe relapse rates exceeding 30% and fails to eradicate intracellular bacteria sequestered in bone.
Option C (Intravenous Ceftriaxone 2 g once daily plus oral Azithromycin 500 mg once daily for 6 weeks): Ceftriaxone does not achieve adequate intracellular concentration for Brucella eradication and is reserved only as an adjunct in neurobrucellosis or endocarditis.
Option D (Oral Amoxicillin-Clavulanate 1 g twice daily plus oral Ciprofloxacin 500 mg twice daily for 6 weeks): Ineffective against intracellular Brucella melitensis; beta-lactams are inadequate for systemic brucellosis.
Exam Trap
Do not prescribe single-agent oral fluoroquinolones or 14-day courses for Brucellosis. Despite rapid initial symptomatic improvement, monotherapy carries a relapse rate exceeding 30% and fails to prevent spinal osteoarticular sequestration.
Key Takeaway
In suspected or confirmed Brucellosis, dual antimicrobial therapy (Doxycycline plus Rifampin) for a minimum of 6 weeks is mandatory. Prolong treatment to 12 weeks if spondylodiscitis is present.
