Question 4 of 5
A 34-y old lifelong nonsmoking male presents for evaluation of dyspnea, fatigue, and nonproductive cough which is worse in the evening. His symptoms have been ongoing for the last 6 months. He is an auto mechanic working in an autobody shop for the last 4 years. He believes his symptoms are work related. Medical history is otherwise negative and he is on no medications. Physical exam and vital signs are normal. CXR and spirometry are normal. What is the most appropriate next step?
Correct Answer: B
Rationale: Symptoms worsening in the evening suggest occupational asthma related to autobody shop exposures (e.g., isocyanates). Repeat spirometry post-exposure can confirm reversible airway obstruction, a key diagnostic step per occupational lung disease guidelines.
Question 5 of 5
An abnormally wide (more than 0.10 second) QRS complex is characteristic of
Correct Answer: D
Rationale: The QRS of the premature complex is prolonged (greater than 0.10 second) and bizarre in appearance. Paroxysmal atrial tachycardia does not display a QRS complex that is greater than 0.10 seconds. Supraventricular tachycardia does not display a wide QRS complex. Escape rhythms may have a P wave that is inverted and located before, during, or after the QRS.
