Question 1

A patient with severe hand tremors and poor hand-breath coordination has difficulty using a standard pressurized MDI. Which device would BEST address this limitation?

Accepted Answer

A breath-actuated MDI that fires automatically on inhalation

Answer

A breath-actuated MDI (BAI) triggers automatically when the patient inhales, eliminating the need to manually coordinate pressing the canister while breathing in.

Question 2

Which spacer or valved holding chamber configuration is most appropriate for an 18-month-old child requiring inhaled corticosteroid therapy?

Accepted Answer

Spacer fitted with an appropriately sized face mask

Answer

Young children who cannot form a proper lip seal around a mouthpiece require a face mask attached to the spacer to ensure an adequate seal and drug delivery.

Question 3

When cleaning a metered-dose inhaler mouthpiece, the recommended method is to:

Accepted Answer

Remove the canister and rinse the plastic mouthpiece with warm water, then air-dry

Answer

Removing the canister and rinsing only the plastic actuator/mouthpiece with warm water prevents blockage from medication residue without damaging the canister or valve.

Question 4

A patient using a pressurized metered-dose inhaler should hold the device in which orientation?

Accepted Answer

Upright with the canister on top and mouthpiece at the bottom

Answer

Holding the MDI upright (canister up, mouthpiece down) ensures the propellant and drug mixture is properly positioned at the valve for accurate dose delivery.

Question 5

The soft mist inhaler (SMI), such as the Respimat, differs from a standard pressurized MDI primarily because it:

Accepted Answer

Produces a slow-moving, long-lasting aerosol cloud without a propellant

Answer

The Respimat uses a spring-driven mechanism to generate a slow, fine mist that travels at a low velocity, requiring less coordination and allowing more time for inhalation.
