1. A patient presents for a comprehensive health history. Which approach best establishes rapport and
promotes a patient-centered interview?
A. Begin with a detailed review of systems to ensure completeness
B. Start with open-ended questions about the patient's concerns
C. Ask only yes-or-no questions to maintain efficiency
D. Begin with family history to identify hereditary risks
Correct Answer: B
Rationale: Open-ended questions such as "Tell me about yourself" or "What brings you in today?" establish
rapport and allow the patient to express concerns in their own words. This approach is less directed than
immediately asking about the chief complaint and promotes a patient-centered interview .
2. During a health history, a patient reports "I've had this cough for about a month." Which follow-up question
best characterizes the symptom using the OLDCARTS framework?
A. "Does anyone in your family have a cough?"
B. "Is the cough productive?"
C. "Have you tried any home remedies?"
D. "Do you smoke cigarettes?"
Correct Answer: B
,Rationale: Asking "Is the cough productive?" follows up with a specific, focused question that characterizes the
symptom. This uses the OLDCARTS mnemonic (Onset, Location, Duration, Character, Aggravating/Alleviating
factors, Radiation, Timing, Severity) .
3. A patient describes chest discomfort as "a heavy pressure behind my breastbone." Which component of
symptom analysis is primarily being documented?
A. Location
B. Quality
C. Radiation
D. Severity
Correct Answer: B
Rationale: Quality describes the character of a symptom, such as pressure, burning, stabbing, throbbing, or
aching. Location identifies where it occurs, while radiation describes movement from the primary site. Severity
addresses intensity .
4. A patient reports that abdominal pain began suddenly after eating. Which additional history question would
best clarify the temporal pattern?
A. "What color is the pain?"
B. "How long does each episode last?"
C. "Do you exercise regularly?"
D. "What is your family history?"
Correct Answer: B
, Rationale: Duration helps characterize the temporal pattern of a symptom and can distinguish intermittent
from persistent processes. Symptom timing includes onset, duration, frequency, progression, and relationship
to activities or exposures .
5. Which documentation is the most objective?
A. "Patient appears unhealthy."
B. "Patient seems anxious."
C. "Patient states that breathing is difficult."
D. "Respiratory rate 30/min with suprasternal retractions."
Correct Answer: D
Rationale: Objective findings are measurable or directly observable by the examiner. Respiratory rate and
visible retractions can be documented objectively, whereas generalized statements such as "unhealthy" are
vague and subjective .
6. A patient says, "My pain is worse when I climb stairs." Which symptom characteristic is being identified?
A. Alleviating factor
B. Aggravating factor
C. Radiation
D. Timing
Correct Answer: B
Rationale: An aggravating factor increases or precipitates a symptom. Identifying what makes a symptom
worse or better can provide important clues about its underlying mechanism and helps guide differential
diagnosis .
