Question

determine whether each statement applies to mdi devices, dpi devices, or both.
statement
slow deep breath with hold is required
used for maintenance on asthma only
available as a sympathomimetic bronchodilator
uses a propellant
fast deep breath with hold is required
available as an anticholinergic bronchodilator
can be used in rescue situations

Explanation:

1. Slow deep breath with hold is required: Both MDI (Metered - Dose Inhaler) and DPI (Dry Powder Inhaler) require a slow deep breath followed by a breath hold to ensure the medication reaches the lungs.
2. Used for maintenance on asthma only: Neither MDI nor DPI are used only for asthma maintenance. They can be used for other respiratory conditions like COPD as well.
3. Available as a sympathomimetic bronchodilator: Both MDI and DPI can be available as sympathomimetic bronchodilators (e.g., albuterol can be in MDI or DPI form in some cases).
4. Uses a propellant: Only MDI uses a propellant to deliver the medication. DPI delivers dry powder without a propellant.
5. Fast deep breath with hold is required: DPI requires a fast deep breath to draw the dry powder into the lungs, while MDI requires a slow deep breath.
6. Available as an anticholinergic bronchodilator: Both MDI and DPI can be available as anticholinergic bronchodilators (e.g., tiotropium can be in DPI form, and some anticholinergics are in MDI form).
7. Can be used in rescue situations: Both MDI (e.g., albuterol MDI) and DPI (in some cases) can be used in rescue situations for acute respiratory distress.

Answer:

• Slow deep breath with hold is required: Both (MDI and DPI)
• Used for maintenance on asthma only: Neither
• Available as a sympathomimetic bronchodilator: Both
• Uses a propellant: MDI
• Fast deep breath with hold is required: DPI
• Available as an anticholinergic bronchodilator: Both
• Can be used in rescue situations: Both
