A clinician explains, "We could order this test, but if it is positive, the next step
would be an invasive procedure that you have already said you would not
want. So the test may not help us make a better decision." This is an example
of:
a) Withholding information
b) Shared decision-making about downstream consequences
c) Defensive medicine
d) Diagnostic delay
e) Ignoring patient autonomy
B
The correct answer option is b) Shared decision-making about downstream
consequences.
Explanation of the Correct Option
• b) Shared decision-making about downstream consequences: This
statement exemplifies shared decision-making because the clinician is
actively collaborating with the patient, respecting their previously stated
values (refusing an invasive procedure), and analyzing the sequential
cascade of medical events (the "downstream consequences"). By pointing out
that a positive test result would only lead to a path the patient explicitly wishes
to avoid, the clinician is ensuring that care remains goal-concordant and that
unnecessary testing is avoided.
Which of the following is the BEST example of safety-netting?
, Page 2 of 35
a) "Your symptoms are probably nothing."
b) "Come back if you feel like it."
c) "Testing is not needed today, but if you develop fever, worsening pain,
weakness, or symptoms persist beyond the expected time frame, we should
reassess."
d) "I'll order tests so we don't miss anything."
e) "The guidelines say not to test."
C
The correct answer option is c) "Testing is not needed today, but if you develop
fever, worsening pain, weakness, or symptoms persist beyond the expected
time frame, we should reassess."
Explanation of the Correct Option
• c) "Testing is not needed today, but if you develop...": In clinical practice,
safety-netting is a vital diagnostic communication strategy used to manage
clinical uncertainty and protect patients from avoidable harm. It ensures that if
a patient is sent home without immediate intervention or testing, they are
given explicit, structured information including:
1. Specific "red flag" symptoms to monitor (fever, worsening pain,
weakness).
2. An expected timeline for recovery (symptoms persisting beyond the
expected time frame).
3. Clear instructions on when and how to seek a medical
reassessment
Why can "more information" sometimes worsen clinical care?
a) Patients usually do not want information
b) Test results are never reliable
c) Extra information can create false positives, incidental findings, anxiety, and
unnecessary follow-up
d) Clinicians should rely only on physical exam
e) More information always improves diagnostic accuracy
C
The correct answer option is c) Extra information can create false positives,
incidental findings, anxiety, and unnecessary follow-up.
Explanation of the Correct Option
• c) Extra information can create false positives, incidental findings,
anxiety, and unnecessary follow-up: In evidence-based medicine, ordering
diagnostic tests or gathering clinical data without a clear, specific indication
, Page 3 of 35
often causes more harm than good. This phenomenon is known as over-
testing.When unnecessary tests are ordered, they frequently uncover benign
abnormalities (incidentalomas) or trigger false-positive results. This forces
the clinician and patient into a cascade of unnecessary specialist referrals,
invasive follow-up biopsies, and heightened psychological anxiety, despite the
patient being fundamentally healthy.
A patient asks whether they should have a test. Which response BEST reflects
high-value care?
a) "Yes, because it is better to know."
b) "No, because I do not think it is needed."
c) "Let's first clarify what question we are trying to answer and what we would
do differently depending on the result."
d) "I can order it if your insurance covers it."
e) "Testing is always a personal choice."
C
The correct answer option is c) "Let's first clarify what question we are trying to
answer and what we would do differently depending on the result."
Explanation of the Correct Option
• c) "Let's first clarify what question...": High-value care is defined as
providing the best possible health outcomes while avoiding unnecessary costs
and clinical harms. This response directly applies the principles of
appropriate test utilization. Before ordering any diagnostic test, a clinician
must evaluate its clinical utility. If the result—whether positive or negative—
will not change the management plan or answer a specific clinical question,
the test adds no value and only exposes the patient to potential false
positives, anxiety, and financial strain.
Which factor MOST increases the chance that a diagnostic test will be
clinically useful?
a) The test is newly available
b) The patient has moderate pre-test probability and the result would change
management
c) The test is commonly ordered
d) The test produces detailed reports
e) The test has a high cost
B
, Page 4 of 35
The correct answer option is b) The patient has moderate pre-test probability and
the result would change management.
Explanation of the Correct Option
• b) The patient has moderate pre-test probability and the result would
change management: A diagnostic test delivers its highest clinical utility
under two conditions:
1. Moderate Pre-Test Probability: Testing is most informative when the
diagnosis is uncertain. If the pre-test probability is extremely low, a
positive result is highly likely to be a false positive. If it is extremely
high, a negative result is likely a false negative.
2. Actionable Results: The test must have the power to alter the clinical
course. If the treatment plan remains identical regardless of whether
the test is positive or negative, the test provides no clinical value.
Which of the following would make imaging more appropriate?
a) The patient is mildly anxious
b) Imaging is available the same day
c) The patient has red flags or a result would change management
d) The clinician wants complete certainty
e) The patient has not had imaging before
C
The correct answer option is c) The patient has red flags or a result would
change management.
Explanation of the Correct Option
• c) The patient has red flags or a result would change management:
Advanced diagnostic imaging is clinically indicated when specific clinical
indicators—known as "red flags"—suggest a potentially serious, underlying
systemic condition (such as cancer, infection, or severe neurological deficit).
Furthermore, imaging is justified if the objective findings will directly alter or
guide the subsequent management or treatment plan. If a result will not
alter the therapeutic approach, the imaging is unnecessary and adds zero
clinical value
Which of the following statements about "just in case" testing is TRUE?
a) It is always safer than watchful waiting
b) It is harmless if the test is non-invasive
c) It can lead to false positives, incidental findings, anxiety, cost, and
unnecessary care cascades
