SECTION 1: DIAGNOSTIC REASONING
FUNDAMENTALS & COGNITIVE BIASES
(Questions 1–30)
, 1. A nurse practitioner uses a dual-process model of
reasoning. Which scenario best describes the
intuitive (Type 1) process?
A) Calculating pre-test probability for pulmonary
embolism using the Wells score
B) Recognizing "sick vs. not sick" within seconds of
entering a patient's room
C) Listing all possible causes of fatigue and ruling
each out systematically
D) Using a clinical decision rule to decide on imaging
for ankle trauma
Answer: B) Recognizing "sick vs. not sick" within
