UC DD EXAM 1 2026 COMPREHENSIVE
STUDY GUIDE WITH VERIFIED SOLUTIONS
◉What are two factors that affect diagnostic reasoning?. Answer:
Patient driven factor or clinician driven factor.
◉What is a patient driven factor that affects reasoning?. Answer:
increasing acuity, poor historians, altered mental status, multisystem
disease: acute & chronic- ppl have acute exacerbations of chronic
diseases: COPD/CHF/ CAD, multiple complaints.
◉What are clinician driven factor that affects reasoning?. Answer:
limited experience, knowledge base, continuous review of data,
demants for cost effectiveness and speed, uncertainty of data:
random high lab value (cmp/bmp). Can't understant why value
elevated in this pt. Sometimes you need to redo the test. Look at
patient and what data says to see if they match.
◉What are the 3 types of diagnostic reasoning?. Answer:
Probabilistic reasoning, causal reasoning and deterministic
reasoning.
◉What is probabilistic reasoning?. Answer: (A+B=C)
, Associations between clinical data that trigger the potential
presence of a disease, demographic description, presenting
manifestations, signs & symptoms, = a probable cause.
◉What is an example of probabilistic reasoning?. Answer: Elderly pt
with confusion. Hx: 6 seeks ago pt was rational and independent.
Fell and hit head, losing consciousness for a little bit of time. Fine the
next day. Possible "Chronic subdural hematoma."
◉What is causal reasoning?. Answer: it is based on cause & effect
relationship between clinical data. Corroboration present.
◉What is an example of causal reasoning?. Answer: Someone with
high triglycerides at risk for pancreatitis/CAD.
◉What is deterministic reasoning?. Answer: (Guides). Things you
know exist like ABC= airway breathing circulation.
Depends on knowledge that exists as unambiguous rules, outline
routine clinical practice, diagnostic algorithms: ACLS, list of rules.
◉What are 2 patterns of diagnostic reasoning?. Answer: Backward
reasoning and forward reasoning.
◉What is backwards reasoning?. Answer: Generates hypothesis then
tries to acquire data to uphold it.
