The client who has emphysema and recently experienced a stroke receives a prescription for a metered-dose inhaler with a spacer device. The client asks the nurse if using the spacer is necessary. Which information should the nurse provide?

It allows time to inhale the entire dispensed dose.

It prevents mouth infections when an inhaler is used.

It allows the medication to slowly enter the lungs.

It increases the effectiveness of the medication.

Answer and Explanation

The Correct Answer is A

Choice A reason: Using a spacer allows time for the client to inhale the entire dispensed dose, ensuring that the medication is delivered effectively to the lungs.

Choice B reason: While a spacer may reduce the risk of oral thrush, it is not specifically intended to prevent mouth infections.

Choice C reason: A spacer does not slow the entry of medication into the lungs; it helps to deliver the medication more effectively.

Choice D reason: While using a spacer can increase the effectiveness of the medication, the primary reason is that it allows the client to inhale the entire dose properly.
