MULTIPLE CHOICE

1. ANS: B + r
Croskerry (2009) describes two major types of clinical diagnostic decision-
+r +r +r +r +r +r +r +r +r
making: intuitive and analytical. Intuitive decision-making (similar to Augenblink decision-
+r +r +r +r +r +r +r +r +r
making) is based on the experience and intuition of the clinician and is less reliable and paired
+r +r +r +r +r +r +r +r +r +r +r +r +r +r +r +r +r
with fairly common errors. In contrast, analytical decision-
+r +r +r +r +r +r +r
making is based on careful consideration and has greater reliabilitywith rare errors.

To obtain adequate history, providers must be well organized, attentive to the patient’s verbal a

ndnonverbal language, and able to accurately interpret the patient’s responses to questions. R
+r +r +r +r +r +r +r +r +r +r +r +r +r
ather than reading into the patient’s statements, they clarify any areas of uncertainty.

Vital signs are part of the physical examination portion of patient assessment, not part of the health

history.

4. ANS: D + r
While performing the physical examination, the examiner must be able to differentiate between
+r +r +r +r +r +r +r +r +r +r +r +r +r
normal and abnormal findings, recall knowledge of a range of conditions, including their associ

ated signs and symptoms, recognize how certain conditions affect the response to other condit

ions, and distinguish the relevance of varied abnormal findings.

Sources for diagnostic statistics include textbooks, primary reports of research, and published
+r +r +r +r +r +r +r +r +r +r +r +r
meta-
analyses. Another source of statistics, the one that has been most widely used and available f
+r +r +r +r +r +r +r +r +r +r +r +r +r +r +r
or application to the reasoning process, is the estimation based on a provider’s experience, al
+r +r +r +r +r +r +r +r +r +r +r +r +r +r
though these are rarely accurate. Over the past decade, the availability of evidence on which
+r +r +r +r +r +r +r +r +r +r +r +r +r +r +r
to base clinical reasoning is improving, and there is an increasing expectation that clinical reas
+r +r +r +r +r +r +r +r +r +r +r +r +r +r
oningbe based on scientific evidence. Evidence-
+r +r +r +r +r +r
based statistics are also increasingly being used to develop resources to facilitate clinical decis

ion-making.

6. ANS: D + r
To assist in clinical decision-making, a number of evidence-
+r +r +r +r +r +r +r +r
based resources have been developedto assist the clinician. Resources, such as algorithms and
+r +r +r +r +r +r +r +r +r +r +r +r +r +r
clinical practice guidelines, assist in clinical reasoning when properly applied.
