The statement indicating a need for further instruction regarding asthma during pregnancy is that bronchodilators should be used only when necessary. In the context of asthma management during pregnancy, it's important for individuals to understand that bronchodilators, which provide quick relief of asthma symptoms, are critical tools in maintaining control over asthma.

In fact, the use of specific bronchodilators may be necessary even when a person feels well, as they help prevent acute exacerbations and ensure that the airways remain open.

Continuing asthma medication as prescribed indicates an understanding of the need for effective treatment while pregnant, aiming to limit asthma attacks shows a proactive approach to managing the condition, and recognizing that oxygen needs are high during an asthma attack aligns with the knowledge that oxygenation is critical for both maternal and fetal health.
