True or False: Patients with asthma may not always demonstrate abnormal spirometry results.

Patients with asthma may not always demonstrate abnormal spirometry results is accurate due to the variable nature of the disease. Asthma can be characterized by intermittent airway obstruction, which means that during some periods, especially when the patient is well-controlled or symptom-free, spirometry results may fall within normal ranges.

Additionally, factors such as the timing of spirometry in relation to symptom exacerbation or medication use can affect results. For instance, if a patient has mild or no symptoms at the time of testing, the lung function may appear normal despite the underlying asthma. This variability underscores the episodic nature of asthma and highlights the importance of comprehensive asthma management that goes beyond spirometry alone, taking into account clinical symptoms and patient history for a more accurate assessment of control over the condition.

The statement reflects an important aspect of asthma management, which clinicians must keep in mind when evaluating patients, as it emphasizes that a single spirometry measurement may not capture the full picture of a patient's respiratory health.
