MULTIPLE CHOICE ju




1. ANS: B
Croskerry (2009) describes two major types of clinical diagnostic decision-making: intuitive and analytical. Intuitive
ju ju ju ju ju ju ju ju ju ju ju ju ju


decision- making (similar to Augenblink decision-making) is based on the experience and intuition of the clinician and
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


is less reliable andpaired with fairly common errors. In contrast, analytical decision-making is based on careful
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


consideration and has greater reliability with rare errors.
ju ju ju ju ju ju ju ju




PTS: 1
2. ANS: D
To obtain adequate history, providers must be well organized, attentive to the patient‘s verbal and nonverbal language, and
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


ableto accurately interpret the patient‘s responses to questions. Rather than reading into the patient‘s statements, they
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


clarify any areas of uncertainty.
ju ju ju ju ju




PTS: 1
3. ANS: C
Vital signs are part of the physical examination portion of patient assessment, not part of the health history.
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju




PTS: 1
4. ANS: D
While performing the physical examination, the examiner must be able to differentiate between normal and abnormal
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


findings, recall knowledge of a range of conditions, including their associated signs and symptoms, recognize how certain
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


conditions affectthe response to other conditions, and distinguish the relevance of varied abnormal findings.
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju




PTS: 1
5. ANS: C
Sources for diagnostic statistics include textbooks, primary reports of research, and published meta-analyses. Another
ju ju ju ju ju ju ju ju ju ju ju ju ju


source of statistics, the one that has been most widely used and available for application to the reasoning process, is the
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


estimation based on a provider‘s experience, although these are rarely accurate. Over the past decade, the availability of
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


evidence on which to base clinical reasoning is improving, and there is an increasing expectation that clinical reasoning be
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


based on scientific evidence.
ju ju ju ju


Evidence-based statistics are also increasingly being used to develop resources to facilitate clinical decision-making.
ju ju ju ju ju ju ju ju ju ju ju ju ju




PTS: 1
6. ANS: D
To assist in clinical decision-making, a number of evidence-based resources have been developed to assist the clinician.
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


Resources, such as algorithms and clinical practice guidelines, assist in clinical reasoning when properly applied.
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju




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
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


positive,result. A high sensitivity indicates that a greater percentage of persons with the given condition will have an
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


abnormal result.
ju ju




PTS: 1
8. ANS: B
The specificity of a diagnostic study is the percentage of normal, healthy individuals who have a normal result. The
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


greater thespecificity, the greater the percentage of individuals who will have negative, or normal, results if they do
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


not have the target condition.
ju ju ju ju ju




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
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


condition and anegative result will be associated with a healthy person. A likelihood ratio above 1 indicates that a
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


positive result is associated with the disease; a likelihood ratio less than 1 indicates that a negative result is associated with
ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju ju


an absence of the disease.
