Challenge: When the examinee counsels you to stop smoking, say “What is the point of quitting now, when I am already sick with a cough?”
Hovering over or clicking on the speech bubbles in the lists below will reveal extra information about the adjacent term. However, clicking on links will cause you to navigate away from the current case, at which point your progress (i.e., your check marks) will be lost. If you do want more information on a subject, either open the link in a new tab or wait until you and your partner have finished the case and reviewed the check marks.

Suggested response to challenge: “Ms. Wright, I understand why you feel like there is no point in stopping to smoke now. However, even after smoking for a long time, quitting can often help you recover from a chronic cough and prevent your problems from getting worse. Also, smoking can cause diseases of the heart and the vessels in your body, which can ultimately result in a heart attack or stroke. By quitting now, you'll significantly decrease the risk of suffering from any of these diseases in the future. At this hospital, we have programs to help you quit smoking and there are also some medical options that we can try out, like nicotine replacement therapy. If you are interested, we can figure out what would work best for you together. How does that sound?”
- Chronic obstructive pulmonary disease (COPD): A chronic cough productive of yellow sputum in a patient with a significant smoking history (70 pack years) should always raise concern for COPD, which is a common disease in the US. Patients typically have a cough that is worse in the mornings and dyspnea on exertion. Advanced stages of COPD can manifest with fatigue, weight loss, and peripheral edema, as reported by this patient.
- Congestive heart failure (CHF): A history of shortness of breath on exertion, nocturia, fatigue, peripheral edema, and a chronic cough are all consistent with CHF. While this patient has several risk factors for CHF, such as arterial hypertension, a smoking history, and lack of exercise, her weight loss and the normal cardiac examination make this diagnosis less likely than COPD.
- Lung cancer: Smoking causes approximately 90% of lung cancers, and the risk increases with the number of pack years. Symptoms such as unintentional weight loss, fatigue, cough, and shortness of breath should raise further suspicion for lung cancer. Although this diagnosis should certainly be ruled out, this patient's risk factors, lack of hemoptysis, and symptoms of COPD and CHF put this diagnosis slightly lower on the list of differential diagnoses.
- Arterial blood gas analysis and pulse oximetry: to assess for oxygen saturation and acid-base balance
- ECG: can show signs of left or right ventricular hypertrophy in CHF as well as signs of concurrent heart conditions (e.g., arrhythmias, cardiac ischemia)
- Transthoracic echocardiogram: gold standard for evaluating patients with heart failure
- Pulmonary function testing: would show a decreased FVC and FEV1, as well as an increased residual volume, intrathoracic gas volume, and total lung capacity in COPD
- BNP, NT-pro BNP: The level of BNP is proportional to ventricular volume and pressure overload. High levels of BNP in patients with classic symptoms of CHF confirm the diagnosis (high predictive index).
- Chest x-ray: used to assess for signs of COPD (e.g., hyperlucency, horizontal ribs, and widened intercostal spaces), signs of CHF (e.g., cardiomegaly or pulmonary congestion), and signs of lung cancer (e.g., solitary nodule, mediastinal widening)
Other differential diagnoses to consider
- Bronchiolitis obliterans
