Which diagnostic procedures should you recommend for the asthma patient?

The recommended diagnostic procedures for asthma patients should focus on assessing lung function and oxygen saturation. Pre-post bronchodilator spirometry measures the amount and speed of air a person can exhale, which is crucial for diagnosing asthma as it can demonstrate reversible airflow obstruction, a hallmark of the condition. This test helps determine the severity of asthma and the response to bronchodilators.

Additionally, pulse oximetry is a non-invasive method to measure blood oxygen levels, which can indicate how well the lungs are functioning and whether the patient is receiving adequate oxygen. Both of these procedures provide essential information specific to asthma management and help guide treatment decisions.

Other options, such as chest X-rays and blood gas analysis, might be useful in certain situations, especially if there are concerns about complications or alternate diagnoses, but they are not specific for asthma evaluation. Similarly, a CT scan may provide detailed images of the lungs but is not routinely used for asthma diagnosis. Peak flow measurements are valuable for monitoring asthma but are not comprehensive enough on their own without the context of spirometry. Skin testing and allergy evaluation are useful for identifying triggers but do not directly assess lung function or asthma severity. Thus, the combination of pre-post bronchodilator spirometry and pulse oximetry is the
