A nurse is teaching the parents of a child who is to start using 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 help improve the delivery of medication from the MDI to the lungs by slowing down the speed of the medication particles, reducing the impact of the medication on the back of the throat, and increasing the amount of medication that reaches the lungs. This ensures better treatment of asthma symptoms.
Explanation of other choices:
A: The spacer actually decreases the amount of medication delivered to the oropharynx, as it helps prevent the medication from impacting the back of the throat.
C: Covering the exhalation slots with lips is incorrect as it can block the flow of medication.
D: Inhaling rapidly with the spacer is incorrect as it may lead to improper medication delivery and inadequate lung deposition.
