What type of inhaler requires a quick, forceful inhalation and cannot use a spacer?

MDI inhalers
DPI inhalers
Soft Mist Inhalers
Nebulizers

The correct answer is: DPI inhalers

DPI (Dry Powder Inhaler) inhalers require a quick, forceful inhalation to effectively deliver the medication into the lungs. Unlike MDI (Metered Dose Inhaler) inhalers, DPI inhalers do not require coordination between actuation and inhalation. MDI inhalers can use a spacer to help with coordination, making the statement incorrect for option A. Soft Mist Inhalers are newer devices that deliver a fine mist of medication slowly and steadily, not requiring a quick, forceful inhalation like DPI inhalers, making option C incorrect. Nebulizers are machines that convert liquid medication into a mist that is inhaled into the lungs over a period of time, not requiring a forceful inhalation like DPI inhalers, making option D incorrect.
