Chapter 1: Assessment and Clinical Decision-Making
1. Which type of clinical decision-making is considered most reliable for accurate
diagnosis?
A. Intuitive
B. Analytical
C. Experiential
D. Augenblick
Rationale: Analytical decision-making involves careful, deliberate, and systematic
consideration of data. It has greater reliability and is associated with fewer errors
compared to intuitive reasoning, which is more automatic and prone to bias .
2. To obtain an adequate patient history, healthcare providers must do all of the
following EXCEPT:
A. Be methodical and systematic
B. Be attentive to the patient's verbal and nonverbal language
C. Accurately interpret the patient's responses
D. Read into the patient's statements to infer meaning
,Rationale: Providers should clarify areas of uncertainty rather than "reading into"
statements, which introduces assumptions and biases into data collection .
3. Essential parts of a health history include all of the following EXCEPT:
A. Chief complaint
B. History of the present illness
C. Current vital signs
D. Review of systems
Rationale: Vital signs are part of the physical examination, not the health history. The
health history includes the chief complaint, HPI, past medical history, family history, and
review of systems .
4. If a diagnostic study has high sensitivity, this indicates:
A. A high percentage of persons with the given condition will have an abnormal
result
B. A low percentage of persons with the given condition will have an abnormal result
C. A low likelihood of normal result in persons without the condition
D. None of the above
Rationale: Sensitivity is the percentage of individuals with the target condition who
show a positive (abnormal) result. The mnemonic "SnNOut" reminds that a highly
Sensitive test, when Negative, rules Out the disease .
5. If a diagnostic study has high specificity, this indicates:
A. A low percentage of healthy individuals will show a normal result
B. A high percentage of healthy individuals will show a normal result
C. A high percentage of individuals with a disorder will show a normal result
D. A low percentage of individuals with a disorder will show an abnormal result
Rationale: Specificity is the percentage of normal, healthy individuals who have a
normal result. The mnemonic "SpPIn" reminds that a highly Specific test, when Positive,
rules In the disease .
6. A likelihood ratio above 1 indicates that a diagnostic test showing a:
A. Positive result is strongly associated with the disease
B. Negative result is strongly associated with absence of the disease
C. Positive result is weakly associated with the disease
D. Negative result is weakly associated with absence of the disease
,Rationale: 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 absence of the disease .
7. Which clinical reasoning tool is defined as an evidence-based resource based on
mathematical modeling to express the likelihood of a condition in select
situations, settings, and/or patients?
A. Clinical practice guideline
B. Clinical decision rule
C. Clinical algorithm
D. Clinical recommendation
Rationale: Clinical decision (or prediction) rules are evidence-based resources that
provide probabilistic statements regarding the likelihood that a condition exists if
certain variables are met. Decision rules use mathematical models and are specific to
certain situations and patient characteristics .
8. The least reliable source of information for determining the probability of a
diagnosis is:
A. Evidence-based investigations
B. Primary reports of research
C. Estimation based on a provider's experience
D. Published meta-analyses
Rationale: Evidence-based investigations, primary research reports, and published
meta-analyses provide systematically evaluated data. Estimation based solely on a
provider's experience is subjective and least reliable .
9. A "zebra" in medical diagnosis refers to:
A. A common condition presenting with typical symptoms
B. An uncommon condition presenting with typical symptoms
C. A common condition presenting with atypical symptoms
D. An uncommon condition presenting with atypical symptoms
Rationale: The adage "when you hear hoofbeats, think of horses, not zebras" reminds
clinicians to consider common diagnoses first. A "zebra" is an uncommon condition
presenting with typical symptoms .
10. The term "pretest probability" refers to:
, A. The probability that a patient has a disease before diagnostic testing
B. The probability that a diagnostic test will be positive
C. The probability that a patient will develop a disease
D. The probability that a treatment will be effective
Rationale: Pretest probability is the probability that a patient has a disease before
diagnostic testing, based on risk factors, symptoms, and clinical presentation .
Chapter 2: Genetic Assessment
11. An autosomal dominant disorder involves the:
A. X chromosome
B. Y chromosome
C. Mitochondrial DNA
D. Non-sex chromosomes
Rationale: Autosomal disorders involve non-sex chromosomes (chromosomes 1–22).
Autosomal dominant means one copy of the altered gene is sufficient to cause the
disorder .
12. According to the Genetic Information Nondiscrimination Act (GINA):
A. NPs should keep all genetic information of patients confidential
B. NPs must obtain informed consent prior to genetic testing of all patients
C. Employers cannot inquire about an employee's genetic information
D. Genetic testing is mandatory for all patients over 65
Rationale: GINA protects individuals from genetic discrimination in health insurance
and employment. Employers cannot inquire about genetic information .
13. A patient shows facial features including epicanthal folds, upslanted palpebral
fissures, single transverse palmar crease, and a low nasal bridge. These are referred
to as:
A. Variable expressivity related to inherited disease
B. Dysmorphic features related to genetic disease
C. De novo mutations of genetic disease
D. Different penetrant signs of genetic disease
