QUESTION 1. What is the BEST description of Autosomal dominant inheritance?
A. One affected heterozygous parent can transmit the variant to approximately half of offspring in each pregnancy.
B. It is defined only by a single symptom and has no physiologic basis.
C. It is unrelated to the underlying disease process or treatment.
D. It should always be managed identically regardless of patient context.
ANSWER: A
RATIONALE: One affected heterozygous parent can transmit the variant to approximately half of offspring in each pregnancy. The safest exam
approach is to connect the mechanism to the expected findings, complications, and treatment implications.
EXAM TRAP: Avoid absolute statements. Pathophysiology questions often test the distinction between a mechanism, a manifestation, and a treatment
implication.
MEMORY CUE: Mechanism → Manifestations → Complications → Management → Monitoring.
