Question

Which statement is true regarding dry powder inhalers (DPIs)?

1 They require more manual dexterity.
2 The medication in them may clump in a humid climate.
3 They require good coordination of puffs with inhalation.
4 They use a chemical propellant to push the medication out of the inhaler.

Answer 1

Dry powder inhalers (DPIs) require good coordination of puffs with inhalation.

Step-by-step explanation:

The true statement regarding dry powder inhalers (DPIs) is 3: They require good coordination of puffs with inhalation.

DPIs deliver medication to the lungs in a powdered form, which requires the patient to inhale forcefully to disperse the medication. This requires coordination between the patient's inhalation and the activation of the device to release the medication.

For example, an albuterol inhaler, which is commonly used to treat asthma, is a type of DPI that requires the patient to inhale quickly and deeply to ensure the medication reaches the lungs effectively.
