30sec Test-Taking Tip for Ethics Questions
It's (almost) never wrong to ask for more info! This includes answer choices that: Ask the patient a question (e.g. "Have you been having thoughts of self-harm?") Seek more context or perspectives (e.g. "I'd like to hear more about your concerns") If multiple choices seek more information, ignore the ones that don't. Then choose the option that most directly and respectfully explores the patient's perspective.
A few rare examples of exceptions: Urgent, complex consent dilemmas: If a parent refuses an emergency life-saving surgery for their child, questions like "Is there a non-operative alternative you'd prefer?" would delay intervention and falsely imply that the parent has the right to refuse medically necessary treatment. Confidentiality: If someone asks for private patient information, a response like "I share your concerns, but may I ask how you are related to her?" would inadvertently divulge that you know the patient. Brain death: If a patient meets criteria for brain death, they're legally deceased, so questions like "Would you like us to consider experimental treatments?" would provide false uncertainty and hope. So remember: when in doubt, ask before telling!

3 High-Yield Paradoxes: COPD, Warfarin, Carbon Monoxide
#1: Oxygen can worsen respiratory failure in COPD COPD → chronically high CO₂ → desensitizes chemoreceptors → patients rely on hypoxic respiratory drive (low O₂ triggers breathing). Over-oxygenation → removes hypoxic drive → causes hypoventilation and further CO₂ retention. Takeaway: In COPD, aim for O₂ saturation of 88%-92%. Any higher, and patients may stop breathing!
#2: Warfarin increases clotting risk before preventing clots Warfarin inhibits vitamin K-dependent clotting factors (II, VII, IX, X) AND natural anticoagulants (Proteins C & S). Proteins C & S have shorter half-lives → depleted first → transient hypercoagulable state initially. Takeaway: Always bridge warfarin therapy with fast-acting heparin until INR is ≥2.0. Otherwise, clotting risk increases!
#3: Carbon monoxide (CO) poisoning causes hypoxia but increases SpO₂ CO binds hemoglobin with over 200 times the affinity of oxygen → oxygen delivery to tissues is severely reduced. Pulse oximetry can't distinguish between oxyhemoglobin and carboxyhemoglobin (COHb), so SpO₂ looks reassuring. Takeaway: Diagnose CO poisoning clinically. Confirm with ABG (carboxyhemoglobin levels), not pulse ox!
Here are a few counterintuitive fun facts that almost always come up on the USMLE.
These topics trip a lot of students up, but once you remember they're the opposite of what they seem, they'll be easy points on your exam!
