Q1. Which feature most strongly supports using a problem
representation during diagnostic reasoning?
A) It condenses the most clinically meaningful information into a concise
summary that helps compare diagnostic possibilities.
B) It eliminates the need to obtain additional history.
C) It guarantees that the first suspected diagnosis is correct.
D) It replaces the physical examination with a diagnostic label.
Correct Answer: A) It condenses the most clinically meaningful information
into a concise summary that helps compare diagnostic possibilities.
Rationale: A problem representation organizes key history and examination
findings into a concise clinical summary. It helps clinicians recognize
patterns, compare competing diagnoses, identify missing information, and
avoid becoming distracted by less relevant details.
Q2. A patient presents with fatigue, weight loss, palpitations, and
tremor. Which additional finding would most strongly increase
suspicion for hyperthyroidism?
A) Cold intolerance
B) Heat intolerance
C) Constipation
D) Bradycardia
Correct Answer: B) Heat intolerance
Rationale: Excess thyroid hormone increases metabolic activity and
sympathetic stimulation. Heat intolerance, tremor, weight loss, palpitations,
and tachycardia are characteristic findings and become more convincing
when several occur together.
Q3. Which finding most strongly suggests that a patient's chronic
symptom represents a potentially serious secondary cause rather
than a benign primary condition?
A) Symptoms that remain stable for several years
B) Symptoms relieved by a predictable trigger avoidance strategy
C) New unexplained weight loss accompanied by progressive symptoms
D) Symptoms that occur only intermittently without functional impairment
,Correct Answer: C) New unexplained weight loss accompanied by progressive
symptoms
Rationale: Unexplained weight loss combined with progressive symptoms
can indicate malignancy, systemic disease, endocrine disorders, infection, or
another significant secondary cause. Such findings warrant further
evaluation rather than reassurance based solely on common diagnoses.
Q4. Which principle should guide selection of a diagnostic test in
primary care?
A) The most expensive test should be selected first.
B) The test should be chosen only after a definitive diagnosis has been
established.
C) Testing should be performed whenever a patient requests it.
D) The test should address a specific clinical question and have potential to
change management.
Correct Answer: D) The test should address a specific clinical question and
have potential to change management.
Rationale: Diagnostic testing is most useful when it addresses an
identifiable clinical question and the result could meaningfully alter
diagnostic probability or management. Unfocused testing increases false
positives, cost, and unnecessary follow-up.
Q5. Which situation is an example of anchoring bias?
A) Continuing to consider alternative diagnoses after obtaining new
information
B) Assuming persistent symptoms must have the same cause as a previous
diagnosis despite contradictory new findings
C) Revising a diagnosis after a new test result
D) Asking another clinician to review an uncertain case
Correct Answer: B) Assuming persistent symptoms must have the same
cause as a previous diagnosis despite contradictory new findings
Rationale: Anchoring occurs when clinicians rely excessively on an initial
impression and fail to sufficiently adjust their thinking when new information
appears. Reassessing the differential when findings do not fit is an important
safeguard.
Q6. Which approach is most appropriate when taking a medication
history from an older adult?
, A) Ask only about prescribed medications.
B) Ask only about medications taken during the past week.
C) Include prescriptions, over-the-counter products, supplements, and how
the patient actually takes them.
D) Rely exclusively on the electronic medication list.
Correct Answer: C) Include prescriptions, over-the-counter products,
supplements, and how the patient actually takes them.
Rationale: Medication reconciliation should identify all substances and the
patient's actual use. Differences between the medication list and real-world
use can explain adverse effects, treatment failure, interactions, and apparent
nonadherence.
Q7. Which finding most strongly indicates a need to assess
functional status in an older adult?
A) New difficulty managing medications and paying bills
B) Preference for an afternoon appointment
C) Longstanding preference for a specific diet
D) Mild seasonal nasal congestion
Correct Answer: A) New difficulty managing medications and paying bills
Rationale: Difficulty with instrumental activities of daily living may indicate
cognitive, physical, psychiatric, or neurologic decline. Functional assessment
provides information that laboratory and cognitive testing alone may not
capture.
Q8. Which communication technique is most useful for determining
whether a patient understands a new treatment plan?
A) Asking, "Do you understand?"
B) Giving a longer written explanation
C) Asking the family member to confirm understanding
D) Using teach-back and asking the patient to explain the plan in their own
words
Correct Answer: D) Using teach-back and asking the patient to explain the
plan in their own words
Rationale: Teach-back evaluates actual comprehension rather than
assuming agreement means understanding. Asking the patient to explain
instructions in their own words can reveal misunderstandings before they
lead to medication or self-management errors.
