Respiratory medications ( 7 Questions)
A client is prescribed a metered-dose inhaler (MDI) and a dry powder inhaler (DPI). The client asks the nurse about the difference between the two types of inhalers. Which of the following responses by the nurse is correct?
Correct. Metered-dose inhalers (MDIs) require the client to coordinate their breathing with inhalation. They release a measured dose of medication in aerosol form, and the client needs to inhale deeply at the same time to ensure the medication reaches the lungs. Dry powder inhalers (DPIs), on the other hand, do not require coordination of breathing and inhalation. The client simply needs to inhale forcefully to activate the powder dispersion.
Incorrect. MDIs contain a propellant that helps atomize the medication and facilitate its delivery into the lungs, but this is not the main difference between MDIs and DPIs.
Incorrect. DPIs deliver the medication in powder form, not mist form.
Incorrect. DPIs do not require the use of a spacer device, unlike MDIs, which can benefit from a spacer device to improve medication delivery.
