A patient develops severe hypotension, rash, and bronchospasm after a bee sting. What is the first-line treatment?
- Antihistamines
- Corticosteroids
- Epinephrine
- Oxygen
Show answer
C. Epinephrine. Intramuscular epinephrine is first-line for anaphylaxis: it reverses hypotension (α1) and bronchospasm (β2). Antihistamines and corticosteroids are only adjuncts.
A 67-year-old woman has fatigue and bone pain. Serum electrophoresis shows an M spike, and bone marrow shows >10% plasma cells. Which additional finding is most likely?
- Auer rods
- Bence Jones proteins in urine
- Hypersegmented neutrophils
- Reed-Sternberg cells
Show answer
B. Bence Jones proteins. This is multiple myeloma: excess free light chains spill into the urine. Auer rods = AML, hypersegmented neutrophils = B12/folate deficiency, Reed-Sternberg cells = Hodgkin lymphoma.
