Answer Section
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.
PTS: 1
7. ANS: A
The sensitivity of a diagnostic study is the percentage of individuals with the target condition who show an abnormal, or positive,
result. A high sensitivity indicates that a greater percentage of persons with the given condition will have an abnormal result.
PTS: 1
8. ANS: B
The specificity of a diagnostic study is the percentage of normal, healthy individuals who have a normal result. The greater the
specificity, the greater the percentage of individuals who will have negative, or normal, results if they do not have the target
condition.
PTS: 1
9. ANS: A
The likelihood ratio is the probability that a positive test result will be associated with a person who has the target condition and a
negative result will be associated with a healthy person. A likelihood ratio above 1 indicates that a positive result is associated
with the disease; a likelihood ratio less than 1 indicates that a negative result is associated with an absence of the disease.
