Understanding Developmental Disabilities: Intro Quiz
Questions
Definition of diagnostic reasoning - correct answer ✔✔Dynamic thinking process that leads to the
identification of a hypothesis that best explains the clinical evidence.
A method of exploring a patient problem using an approach that is systematic and organized, resulting
into the generation of a hypothesis.
What are two factors that affect diagnostic reasoning? - correct answer ✔✔Patient driven factor or
clinician driven factor.
What is a patient driven factor that affects reasoning? - correct 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? - correct 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? - correct answer ✔✔Probabilistic reasoning, causal
reasoning and deterministic reasoning.
What is probabilistic reasoning? - correct 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? - correct 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? - correct answer ✔✔it is based on cause & effect relationship between clinical
data. Corroboration present.
, What is an example of causal reasoning? - correct answer ✔✔Someone with high triglycerides at risk for
pancreatitis/CAD.
What is deterministic reasoning? - correct 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? - correct answer ✔✔Backward reasoning and forward
reasoning.
What is backwards reasoning? - correct answer ✔✔Generates hypothesis then tries to acquire data to
uphold it.
-seen with novice clinician, lack of knowledge inhibits construction from data alone, inefficient, earlier
ROS may help trigger development
What is forward reasoning? - correct answer ✔✔uses data item of set to generate hypothesis.
Characteristic of experts, dependent on solid knowledge of symptomology, highly efficient.
Definition of diagnositc process? - correct answer ✔✔Combination of systematic analysis and intuitive
knowledge.
What does systematic analysis involve? - correct answer ✔✔Involves use of explicit knowledge.
What is explicit knowledge? - correct answer ✔✔knowledge of physical or psychological states,
conditions, or diseases and their associated probabilities, pathophyiological mechanisms and clinical
manifestations.
Diagnostic reasoning is - correct answer ✔✔Dynamic thinking process that leads to the identification of
a hypothesis that best explains the clinical evidence.
Backward reasoning: - correct answer ✔✔Generates hypothesis then tries to acquire data to uphold it.
