Q1 QUESTION 1 OF 60
What is the most appropriate next step for a 70-year-old patient whose asthma is worsening despite
adherence to low-dose ICS/LABA?
CORRECT ANSWER
Evaluate for comorbid conditions such as GERD or rhinosinusitis.
RATIONALE
Worsening asthma symptoms despite guideline-directed therapy necessitate investigating contributing comorbid
conditions like gastroesophageal reflux disease or rhinosinusitis, which can exacerbate airway inflammation. This
approach is key to identifying and managing factors that impede asthma control.
Q2 QUESTION 2 OF 60
Why is diagnosing influenza in older adults particularly challenging?
CORRECT ANSWER
Influenza symptoms can be mild and nonspecific.
RATIONALE
Older adults often present with atypical or subtle influenza symptoms, lacking the classic fever and cough, making
early recognition difficult. This atypical presentation challenges diagnostic accuracy due to the absence of
pathognomonic signs.
Q3 QUESTION 3 OF 60

, Which pathogen is most likely responsible for community-acquired pneumonia in a patient with COPD and
smoking history?
CORRECT ANSWER
Haemophilus influenzae.
RATIONALE
*Haemophilus influenzae* is a common cause of community-acquired pneumonia, particularly in individuals with
compromised respiratory defenses due to COPD and smoking, which impair mucociliary clearance and increase
susceptibility to bacterial colonization. The key concept tested is the identification of common bacterial pathogens
in immunocompromised hosts with specific risk factors.
Q4 QUESTION 4 OF 60
What is the minimum apnea-hypopnea index (AHI) required to diagnose obstructive sleep apnea (OSA) in the
absence of symptoms?
CORRECT ANSWER
AHI > 15 episodes per hour.
RATIONALE
An apnea-hypopnea index exceeding 15 events per hour, even without overt symptoms, signifies sufficient
respiratory disruption to meet diagnostic criteria for obstructive sleep apnea. This threshold reflects significant
sleep-disordered breathing that can lead to adverse health outcomes.
Q5 QUESTION 5 OF 60
What are the benefits of using PA views for chest x-ray diagnosis?
CORRECT ANSWER
They help examine superimposed structures and monitor disease progression.
RATIONALE
Posterior-anterior (PA) chest x-rays project the heart and mediastinum closer to the detector, minimizing
magnification and distortion thereby allowing for more accurate assessment of superimposed structures and serial
monitoring of disease progression. This standardization of projection is key for comparative diagnostic
interpretation.
