A nurse is reinforcing teaching with the parents of a child who is starting to use a spacer with a metered-dose inhaler (MDI) to treat asthma. Which of the following information should the nurse include in the teaching?
Correct answer
B
Rationale
The correct answer is B: The spacer increases the amount of medication delivered to the lungs. Spacers are used with MDIs to improve medication delivery by reducing the need for precise coordination between inhalation and actuation. Spacers also help to slow down the medication particles, allowing more to reach the lungs for better effectiveness. Choice A is incorrect as inhaling rapidly can lead to improper medication delivery. Choice C is incorrect as the spacer is designed to prevent medication deposition in the oropharynx. Choice D is incorrect as covering the exhalation slots can prevent proper inhalation technique.
