Respiratory Medicine
Q1
When is a comprehensive patient assessment appropriate?
CORRECT ANSWERAppropriate for new patients in the office or hospital; provides fundamental and
personalized knowledge; strengthens clinician-patient relationship; helps identify or rule out
physical causes; provides baseline for future assessments; creates platform for health
promotion; develops proficiency in physical assessment skills
CLINICAL RATIONALE
● Comprehensive assessment establishes a complete health baseline for comparison with future visits.
● Builds trust and rapport through thorough evaluation of all body systems.
Q2
When is a focused patient assessment appropriate?
CORRECT ANSWER Appropriate for established patients, especially during routine or urgent care
visits; addresses focused concerns or symptoms; assesses symptoms restricted to a specific body
system
CLINICAL RATIONALE
● Focused assessment is time-efficient for known patients with acute complaints.
● Targets only the relevant body system related to the chief complaint.
Q3
What information is considered subjective in the clinical record?
CORRECT ANSWERThe clinical record from Chief Complaint (CC) through Review of Systems (ROS);
includes symptoms (health concerns patient tells provider); includes feelings, perceptions, and
concerns obtained from clinical interview
CLINICAL RATIONALE
● Subjective data is what the patient tells you (cannot be measured).
● Includes chief complaint, HPI, ROS, and past medical/family/social history.
,Q4
What information is considered objective in the clinical record?
CORRECT ANSWER All physical examination findings, laboratory information, and test data are
objective data
CLINICAL RATIONALE
● Objective data is measurable, observable, and verifiable.
● Vital signs, physical exam findings, labs, imaging, and other diagnostic tests.
Q5
What are the components of a comprehensive adult health history?
CORRECT ANSWERInitial information (identifying patient information/source/reliability), Chief
Complaint(s), History of Present Illness, Past Medical History, Family History, Personal/Social
History, Review of Systems (ROS)
CLINICAL RATIONALE
● This structure ensures no critical information is omitted.
● Provides a complete picture of the patient's health status.
Q6
What does the SNAPPS method stand for in clinical education?
CORRECT ANSWER Summarize the history and findings; Narrow the differential diagnosis to 2-3
possibilities; Analyze the differential by comparing and contrasting possibilities; Probe the
preceptor by asking questions about alternative approaches; Plan the management of the
patient's health issues; Select an issue from the case for self-directed learning
CLINICAL RATIONALE
● SNAPPS is a learner-centered model for case presentations.
● Encourages active clinical reasoning and self-directed learning.
Q7
What does the clinical saying "Hoofbeats = Horses NOT Zebras" mean in differential diagnosis?
CORRECT ANSWERWhen you hear hoofbeats, think of common causes (horses) first, not rare
conditions (zebras)
CLINICAL RATIONALE
● Common diseases are common; rare diseases are rare.
● Start with most likely diagnoses before considering unusual conditions.
, Q8
What are the steps for creating a differential diagnosis?
CORRECT ANSWER 1) Start with broad list; 2) List top diagnosis first; 3) Aggressively prioritize most
likely and most harmful/life-threatening; 4) Prioritize acute and reversible then chronic and
irreversible; 5) Remove diagnoses as they are ruled out; 6) Once diagnosis confirmed, problem
list should be diagnosis-oriented
CLINICAL RATIONALE
● Systematic approach reduces diagnostic errors.
● Always rule out life-threatening causes first (e.g., MI, PE, sepsis).
Q9
What is a pertinent positive finding?
CORRECT ANSWER Symptoms or signs that are present that you would expect to find if a possible
cause for a patient's problem were true, which then supports the diagnosis
CLINICAL RATIONALE
● Pertinent positives help confirm a suspected diagnosis.
● Example: Chest pain radiating to left arm in suspected MI.
Q10
What is a pertinent negative finding?
CORRECT ANSWER Expected symptoms or signs that are NOT present; facts that you would expect to
find if a possible cause were true, which weaken this diagnosis by their absence
CLINICAL RATIONALE
● Pertinent negatives help rule out suspected diagnoses.
● Example: No fever in a patient with suspected pneumonia.
Q11
What is evidence-based medicine?
CORRECT ANSWERThe conscientious, explicit, judicious and reasonable use of modern, best
evidence in making decisions about the care of individual patients
CLINICAL RATIONALE
● Integrates clinical expertise with best available research evidence.
● Also incorporates patient values and preferences.
