MULTIPLE |CHOICE
1. ANS: | | B
Croskerry |(2009) |describes |two |major |types |of |clinical |diagnostic |decision-making: |intuitive |and
|analytical. |Intuitive |decision-making |(similar |to |Augenblink |decision-making) |is |based |on |the
|experience |and |intuition |of |the |clinician |and |is |less |reliable |and |paired |with |fairly |common |errors. |In
|contrast, |analytical |decision-making |is |based |on |careful |consideration |and |has |greater |reliability |with
|rare |errors.
PTS: 1
2. ANS: | | D
To |obtain |adequate |history, |providers |must |be |well |organized, |attentive |to |the |patient’s |verbal |and
|nonverbal |language, |and |able |to |accurately |interpret |the |patient’s |responses |to |questions. |Rather |than
|reading |into |the |patient’s |statements, |they |clarify |any |areas |of |uncertainty.
PTS: 1
3. ANS: | | C
Vital |signs |are |part |of |the |physical |examination |portion |of |patient |assessment, |not |part |of |the |health
|history.
PTS: 1
4. ANS: | | D
While |performing |the |physical |examination, |the |examiner |must |be |able |to |differentiate |between
|normal |and |abnormal |findings, |recall |knowledge |of |a |range |of |conditions, |including |their |associated
|signs |and |symptoms, |recognize |how |certain |conditions |affect |the |response |to |other |conditions, |and
|distinguish |the |relevance |of |varied |abnormal |findings.
PTS: 1
5. ANS: | | C
Sources |for |diagnostic |statistics |include |textbooks, |primary |reports |of |research, |and |published
|meta-analyses. |Another |source |of |statistics, |the |one |that |has |been |most |widely |used |and |available
|for |application |to |the |reasoning |process, |is |the |estimation |based |on |a |provider’s |experience,
|although |these |are |rarely |accurate. |Over |the |past |decade, |the |availability |of |evidence |on |which |to
|base |clinical |reasoning |is |improving, |and |there |is |an |increasing |expectation |that |clinical |reasoning
|be |based |on |scientific |evidence. |Evidence-based |statistics |are |also |increasingly |being |used |to
|develop |resources |to |facilitate |clinical |decision-making.
PTS: 1
6. ANS: | | D
To |assist |in |clinical |decision-making, |a |number |of |evidence-based |resources |have |been |developed |to
|assist |the |clinician. |Resources, |such |as |algorithms |and |clinical |practice |guidelines, |assist |in |clinical
|reasoning |when |properly |applied.
