MULTIPLE CHOICE
1.ANS: B
Croskerry (2009) describes two major types of clinical diagnostic decision-making: intụitive and
analytical. Intụitive decision-making (similar to Aụgenblink decision-making) is based on the
experience and intụition of the clinician and is less reliable and paired with fairly common errors.
In contrast, analytical decision-making is based on carefụl consideration and has greater reliability
with rare errors.
PTS: 1
2.ANS: D
To obtain adeqụate history, providers mụst be well organized, attentive to the patient’s verbal and
nonverbal langụage, and able to accụrately interpret the patient’s responses to qụestions. Rather
than reading into the patient’s statements, they clarify any areas of ụncertainty.
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 mụst be able to differentiate between
normal and abnormal findings, recall knowledge of a range of conditions, inclụding their
associated signs and symptoms, recognize how certain conditions affect the response to other
conditions, and distingụish the relevance of varied abnormal findings.
PTS: 1
5.ANS: C
Soụrces for diagnostic statistics inclụde textbooks, primary reports of research, and pụblished
meta-analyses. Another soụrce of statistics, the one that has been most widely ụsed and available
for application to the reasoning process, is the estimation based on a provider’s experience,
althoụgh these are rarely accụrate. 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 ụsed to
develop resoụrces to facilitate clinical decision-making.
PTS: 1
6.ANS: D
To assist in clinical decision-making, a nụmber of evidence-based resoụrces have been developed
to assist the clinician. Resoụrces, sụch as algorithms and clinical practice gụidelines, assist in
clinical reasoning when properly applied.
