USMLE Step 2 CK · Cardiology
A 62-year-old woman has 2 months of progressive dyspnea and raised JVP. Chest X-ray shows cardiomegaly with clear lung fields. Echo shows a normal ejection fraction with biatrial enlargement. Most likely diagnosis?
- ARestrictive cardiomyopathy
- BDilated cardiomyopathy
- CHypertrophic cardiomyopathy
- DConstrictive pericarditis
TeachBack™ explanation
Preserved EF + biatrial enlargement + clear lungs is classic restrictive physiology: stiff ventricles that still contract normally.
Restrictive cardiomyopathy and constrictive pericarditis look alike on echo. History (radiation, TB, surgery) and pressure equalization on cath tell them apart.
B: EF would be reduced. C: septal hypertrophy on echo. D: pericardial thickening or calcification on imaging.
Lesson · Pharmacology · Beta blockers
Beta-1 selective blockers (metoprolol, atenolol, bisoprolol) are preferred in reactive airway disease because they cause less bronchoconstriction. At higher doses, however, selectivity is lost…
“Explain this like a tutor”
Lesson tutor · plain language
Selectivity depends on dose. Think of a filter: at low doses it screens out beta-2 receptors; at high doses the filter leaks.
“Selective at low, sloppy at high.” Boards love the asthma patient on high-dose metoprolol who starts wheezing.
Cardioselective blockers are acceptable in mild asthma at the lowest effective dose, never in severe disease.

FAQ
Common questions
Something else? .
What is TeachBack™?
TeachBack™ is Tutor Mode™, reimagined: Regulated Science Institute's tutoring layer built into every lesson and QBank question. After each answer it walks you through the stem, the key clue, the trap, why each wrong option is wrong, and what to review next, with audio you can replay anywhere.
Is TeachBack™ just a study chatbot?
No. It is built into the lessons and question explanations themselves, so you never have to know the right thing to ask. It is also connected to your answers, your confidence, and your study plan, which a separate chat window is not.
How is Regulated Science Institute different from a traditional QBank?
A traditional QBank tells you right or wrong and shows a short explanation. Regulated Science Institute explains the reasoning, every distractor, and the exam trap, adds audio, separates real mastery from lucky guesses, and turns your misses into a review plan.
How do you keep content accurate?
Content is built from trusted sources against each exam's outline, then checked for answer-key consistency, citation support, duplicates, and item quality. Flagged items go to subject matter experts before learners see them, and learner reports feed ongoing fixes. Review depth can vary by course and release stage.
Can I try it before I buy?
Yes. Every exam has a free 20-question quiz with full TeachBack™ explanations. No account or credit card needed.
Why is it more affordable than other prep?
Our platform reduces production overhead, so we can offer a complete exam prep, with QBank, lessons, audio, flashcards and a study plan, for $150 with one year of access and no subscription.
Do you work with schools and employers?
Yes. Programs get the same TeachBack™ engine plus cohort readiness analytics, at-risk learner flags, SSO and LMS integration, and volume pricing.
