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

2. ANS: D L L
To obtain adequate history, providers must be well organized, attentive to the patient’s verbal and
L L L L L L L L L L L L L L
nonverbal language, and able to accurately interpret the patient’s responses to questions. Rather
L L L L L L L L L L L L L
than reading into the patient’s statements, they clarify any areas of uncertainty.
L L L L L L L L L L L L
PTS: 1
3. ANS: C L L
Vital signs are part of the physical examination portion of patient assessment, not part of the health
L L L L L L L L L L L L L L L L
history.
L
PTS: 1
4. ANS: D L L
While performing the physical examination, the examiner must be able to differentiate between
L L L L L L L L L L L L
normal and abnormal findings, recall knowledge of a range of conditions, including their
L L L L L L L L L L L L L
associated signs and symptoms, recognize how certain conditions affect the response to other
L L L L L L L L L L L L L
conditions, and distinguish the relevance of varied abnormal findings.
L L L L L L L L L
PTS: 1
5. ANS: C L L
Sources for diagnostic statistics include textbooks, primary reports of research, and published
L L L L L L L L L L L
meta-analyses. Another source of statistics, the one that has been most widely used and available
L L L L L L L L L L L L L L L
for application to the reasoning process, is the estimation based on a provider’s experience,
L L L L L L L L L L L L L L
although these are rarely accurate. Over the past decade, the availability of evidence on which to
L L L L L L L L L L L L L L L L
base clinical reasoning is improving, and there is an increasing expectation that clinical reasoning
L L L L L L L L L L L L L L
be based on scientific evidence. Evidence-based statistics are also increasingly being used to
L L L L L L L L L L L L L
develop resources to facilitate clinical decision-making.

PTS: 1
6. ANS: D L L
To assist in clinical decision-making, a number of evidence-based resources have been developed to
L L L L L L L L L L L L L
assist the clinician. Resources, such as algorithms and clinical practice guidelines, assist in
L L L L L L L L L L L L L
clinical reasoning when properly applied.
