A client with chronic obstructive pulmonary disease (COPD) is prescribed a metered-dose inhaler (MDI) with a spacer. Which instruction should the nurse reinforce to ensure correct use?

  • A. Inhale deeply and slowly after activating the MDI.
  • B. Hold the breath for 5 seconds after inhaling the medication.
  • C. Rinse the mouth immediately after using the MDI.
  • D. Exhale fully before placing the mouthpiece in the mouth.
Correct Answer: A

Rationale: Inhaling deeply and slowly after activating the MDI is the correct instruction to ensure effective delivery of the medication to the lungs. This technique helps the medication reach the lower airways where it can be most beneficial in managing COPD symptoms. Inhaling too quickly or not deeply enough may result in improper drug delivery and reduce the effectiveness of the treatment. Holding the breath for 5 seconds after inhaling the medication (Choice B) may not be necessary and could cause discomfort without additional benefits. Rinsing the mouth immediately after using the MDI (Choice C) is not necessary unless specified by the healthcare provider. Exhaling fully before placing the mouthpiece in the mouth (Choice D) is not ideal as it may result in inadequate medication delivery to the lungs.
