Asthma Management: Step Therapy and Spirometry Nuances

Asthma is a chronic inflammatory disorder of the airways that frequently appears on both the AANP and ANCC exams. When evaluating a patient with suspected asthma, you must know how to interpret spirometry, which is the gold standard for diagnosis. Look for a reduced FEV1/FVC ratio (less than 70%) that demonstrates reversibility—defined as an improvement of 12% and 200 mL in FEV1 after administration of a short-acting beta-agonist (SABA).

Board questions love to test your knowledge of step therapy. Remember that the cornerstone of persistent asthma management is inhaled corticosteroids (ICS). For mild intermittent asthma, as-needed low-dose ICS-formoterol is now preferred over SABA alone to reduce the risk of severe exacerbations. Always assess inhaler technique and adherence before stepping up therapy.

Clinical Pearl: Never prescribe a long-acting beta-agonist (LABA) as monotherapy in asthma; it is associated with an increased risk of-cardiovascular death. LABAs must always be combined with an inhaled corticosteroid.

COPD: Differentiating Chronic Bronchitis and Emphysema

Chronic Obstructive Pulmonary Disease (COPD) is characterized by persistent respiratory symptoms and airflow limitation that is not fully reversible. On your boards, you will need to distinguish between the two classic phenotypes: chronic bronchitis ("blue bloaters") and emphysema ("pink puffers"). Chronic bronchitis presents with a chronic productive cough for at least 3 months in two consecutive years, whereas emphysema involves the destruction of alveoli leading to barrel chest, dyspnea, and minimal cough.

Management focuses on smoking cessation, which is the single most effective intervention to alter the natural history of COPD. Pharmacotherapy relies on long-acting bronchodilators (LAMA or LABA). For patients with frequent exacerbations, adding an ICS or roflumilast may be indicated.

Board Tip: When a COPD patient presents with an acute worsening of dyspnea, increased sputum volume, and purulent sputum, start empiric antibiotics alongside systemic corticosteroids and bronchodilators. The most common bacterial pathogens are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.

Community-Acquired Pneumonia: Outpatient Empiric Treatment

Community-Acquired Pneumonia (CAP) questions will test your ability to select the correct empiric antibiotic regimen for an otherwise healthy adult versus one with comorbidities or recent antibiotic use. For a healthy adult with no recent antibiotic use within the past 3 months and no significant comorbidities, the first-line outpatient choices are amoxicillin (high dose), doxycycline, or a macrolide (only if local pneumococcal resistance is less than 25%).

If the patient has comorbid conditions (such as chronic heart, lung, liver, or renal disease, diabetes, alcoholism, malignancies, or asplenia) or has used antibiotics recently, you must step up coverage. In these cases, prescribe a respiratory fluoroquinolone (e.g., levofloxacin) or combination therapy with amoxicillin/clavulanate plus a macrolide or doxycycline.

Clinical Pearl: Always check a chest X-ray to confirm the diagnosis of pneumonia, but remember that radiographic infiltrates can lag behind clinical symptoms by up to 24 to 48 hours.

Pulmonary Embolism: Risk Stratification and Diagnostics

Pulmonary Embolism (PE) is a high-stakes emergency that frequently appears wrapped in post-operative, immobilization, or hypercoagulable risk factors. Classic symptoms include sudden-onset dyspnea, pleuritic chest pain, and tachycardia. When faced with a patient presenting with suspected PE, your first step in clinical practice—and on the boards—is to assess clinical probability using the Wells Criteria or Revised Geneva Score.

For low-to-intermediate probability, order a high-sensitivity D-dimer. A negative D-dimer effectively rules out PE in a low-risk patient. However, if the patient is high risk, skip the D-dimer entirely and proceed directly to diagnostic imaging, with a CT pulmonary angiography (CTPA) being the imaging modality of choice (unless contraindicated by severe renal failure or contrast allergy, where a ventilation-perfusion [V/Q] scan is used).

You have got this! Pulmonology can feel dense with guidelines and diagnostic pathways, but by breaking down conditions into clear clinical presentations and gold-standard diagnostics, you are building the exact foundation you need to pass your board exam.
