Note: Line 1702 in the document has a formatting error — for Q "antidote for benzodiazepine overdose," the~(correct answer marker) is on Naloxone, but this conflicts with pharmacology (Flumazenil is the correct antidote for benzodiazepines; Naloxone is for opioids). This appears to be a document typo. All flashcards below use the pharmacologically correct answers.
📚 Pharmacology 2 — Flashcard Set (150 Questions)
Topics covered: Antiarrhythmics · Antihypertensives · GI drugs (PPIs, gastroprotectants, antiemetics, laxatives) · Respiratory drugs · Antidotes & Misc.
🫀 ANTIARRHYTHMICS
FC 1
Q: Which antiarrhythmic class blocks K⁺ channels and prolongs the QT interval?
A: Class III
🧠 Trick: "KIIIum" — Class III = Potassium (K) channel blockers. Think K has 3 letters in "potashium"… no wait — just remember: III = K+
FC 2
Q: What is the primary mechanism of lidocaine in ventricular tachycardia?
A: Sodium channel blockade (Class I)
🧠 Trick: Lidocaine = Lines the sodium door shut. "LidoNa" — Na = sodium.
FC 3
Q: Which antiarrhythmic causes thyroid dysfunction with long-term use?
A: Amiodarone
🧠 Trick: AMiodarone contains IOdine → iodine overloads the thyroid. "AMI-IODINE" — the iodine in its name is a hint!
FC 4
Q: A patient with SVT gets adenosine. What if that fails? Which drug is next (Class II antiarrhythmic)?
A: Propranolol (beta-blocker = Class II)
🧠 Trick: Class II = Beta-blockers = Brakes on the heart rate. "-olol" suffix = beta-blocker (propranolol, metoprolol, atenolol).
FC 5
Q: Which Class IV antiarrhythmic slows AV conduction?
A: Verapamil (calcium channel blocker)
🧠 Trick: Class IV = Verapamil = Vein-of-calcium-blocker. 4 letters in "VERA" — V-E-R-A!
💊 ANTIHYPERTENSIVES
FC 6
Q: Which antihypertensive causes a persistent dry cough?
A: ACE inhibitors (e.g., Enalapril, Lisinopril)
🧠 Trick: ACE gives you a cough ACE in the throat. "Enalapril → E = Enough coughing!"
FC 7
