Which combination increases bleeding risk by additive antiplatelet effects: aspirin plus what?
Which combination increases bleeding risk by additive antiplatelet effects: aspirin plus what?
Tap to reveal answer
Clopidogrel (or other antiplatelet agents). Aspirin and clopidogrel both inhibit platelet aggregation through different mechanisms, resulting in amplified anticoagulant effects and heightened hemorrhage potential.

Which drug class plus NSAIDs commonly causes acute kidney injury from reduced renal perfusion?
Which drug class plus NSAIDs commonly causes acute kidney injury from reduced renal perfusion?
Tap to reveal answer
ACE inhibitors/ARBs (especially with diuretics: “triple whammy”). ACE inhibitors/ARBs reduce glomerular filtration pressure, and NSAIDs further impair renal blood flow via prostaglandin inhibition, especially with diuretics causing volume depletion.

Tap to reveal answer
Tyramine-rich foods (aged cheese, cured meats, draft beer). MAOIs inhibit tyramine metabolism, allowing its accumulation to displace norepinephrine and trigger a sympathomimetic crisis with severe hypertension.

What is the most serious adverse effect of warfarin therapy that requires urgent evaluation?
What is the most serious adverse effect of warfarin therapy that requires urgent evaluation?
Tap to reveal answer
Major bleeding (e.g., intracranial or GI hemorrhage). Warfarin inhibits vitamin K-dependent clotting factors, and excessive anticoagulation can lead to life-threatening hemorrhages in critical areas like the brain or gastrointestinal tract.

Which foods decrease warfarin effect by increasing vitamin K intake?
Which foods decrease warfarin effect by increasing vitamin K intake?
Tap to reveal answer
Leafy green vegetables (e.g., spinach, kale, broccoli). High vitamin K content in these vegetables promotes synthesis of clotting factors, antagonizing warfarin's anticoagulant mechanism and reducing its therapeutic efficacy.
