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

2. ANS: D vvv vvv
To obtain adequate history, providers must be well organized, attentive to the patient’s
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
verbal and nonverbal language, and able to accurately interpret the patient’s responses
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
to questions. Rather than reading into the patient’s statements, they clarify any areas
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
of uncertainty.

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

the health history.

While performing the physical examination, the examiner must be able to differentiate
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
between normal and abnormal findings, recall knowledge of a range of conditions,
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
including their associated signs and symptoms, recognize how certain conditions affect
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
the response to other conditions, and distinguish the relevance of varied abnormal
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
findings.

5. ANS: C vvv vvv
Sources for diagnostic statistics include textbooks, primary reports of research, and
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
published meta-analyses. Another source of statistics, the one that has been most
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
widely used and available for application to the reasoning process, is the estimation
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
based on a provider’s experience, although these are rarely accurate. Over the past
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
decade, the availability of evidence on which to base clinical reasoning is improving,
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
and there is an increasing expectation that clinical reasoning be based on scientific
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
evidence. Evidence-based statistics are also increasingly being used to develop
vvv vvv vvv vvv vvv vvv vvv vvv vvv vvv
resources to facilitate clinical decision-making.

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