Which of the following is true about the Pulmicort Flexhaler?

The statement about the Pulmicort Flexhaler suggesting that one should breathe deeply and forcefully during inhalation is accurate. It emphasizes the correct technique for using this dry powder inhaler to ensure effective drug delivery. When using a dry powder inhaler like the Pulmicort Flexhaler, a strong, deep inhalation helps to ensure that the medication reaches the lungs optimally. This aids in maximizing the therapeutic effect of the medication delivered.

Other techniques like shaking the inhaler after loading it are not appropriate for dry powder inhalers, as they do not contain propellants that require agitation. Inhaling through the nose is not the recommended method; rather, it is vital to inhale through the mouth to receive the medication properly. Additionally, holding the inhaler upside down would also not facilitate correct medication delivery; the device is intended for use in a specific orientation to optimize its effectiveness. Therefore, the recommendation to breathe deeply and forcefully is a critical aspect of proper inhaler use and promotes positive outcomes in asthma management.
