Answer: compression ultrasound

Flashcard 3272: Patients with the AB blood type cannot receive which blood types?_____

Answer: None

Flashcard 3273: Which type of macular degeneration (dry or wet) is more common (>80%)? _____

Answer: Dry (nonexudative)

Flashcard 3274: What type of murmur is classically heard at the apex in a patient with acute mitral regurgitation?

Answer: Early systolic murmur

Extra: In acute mitral regurgitation (e.g., due to papillary muscle rupture or chordae tendineae rupture), the left atrium is relatively non-compliant. The rapid increase in left atrial pressure during systole quickly reduces the pressure gradient between the left ventricle and left atrium, causing the murmur to cease before the second heart sound (S2). This contrasts with chronic mitral regurgitation, which is typically holosystolic.

Flashcard 3275: Which classes of steroid hormones are increased in Cushing syndrome/disease?_____

Answer: glucocorticoids (cortisol) +/- androgens
