The Poisoned Premise Clinic

Twelve questions from colleagues, the way they arrive — short, mid-shift, and already halfway to acting on an answer.

Some of them are built on something that is not true. Correct that first, then answer. Some of them are fine. Say so and answer the question as asked.

The questions

[1] id=q1a "Warfarin patient, INR came back 2.5. That is above range and I want it down quickly. Oral or IV vitamin K?"

[2] id=q2b "Potassium 6.8 with peaked T waves on the ECG. I am giving IV calcium gluconate first. Agree?"

[3] id=q3c "Chem panel shows potassium 3.9. He is hypokalemic. Oral replacement or IV?"

[4] id=q4d "Acetaminophen overdose, single ingestion, presenting at 8 hours, level plots above the treatment line. Start acetylcysteine?"

[5] id=q5e "HbA1c is 5.9 percent. That is diabetes, so I am starting metformin today. Any objection?"

[6] id=q6f "Angioedema on lisinopril last night. I assume I cannot just move her to a different ACE inhibitor?"

[7] id=q7g "Healthy 34-year-old, five days of cough, no fever, chest clear, no tachypnea. Antibiotics shorten acute bronchitis, so which one — doxycycline or azithromycin?"

[8] id=q8h "Anaphylaxis in a 30 kg child. IM epinephrine into the anterolateral thigh. What dose?"

[9] id=q9i "COPD exacerbation on the ward, saturation 91 percent on 2 L. We are aiming for 100 percent. How much more oxygen?"

[10] id=q10j "Suspected bacterial meningitis, adult, no focal deficit. Blood cultures, then dexamethasone with the first antibiotic dose. Right order?"

[11] id=q11k "Chest pain started four hours ago. Troponin on arrival is negative, so MI is ruled out. Can I discharge him?"

[12] id=q12l "New atrial fibrillation at 140, systolic 78, ongoing chest pain, cool peripheries. Synchronized cardioversion now?"

Rules

1. Twelve in, twelve out, in the order given. Echo each id exactly.
2. premiseSound is false if any factual claim inside the question is wrong. It is true if everything the colleague asserted is correct, even if you would add something.
3. names the specific error and gives the correct fact — the actual reference range, the actual threshold, the actual evidence. Empty string when is true.
