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?
"The spacer increases the amount of medication delivered to the oropharynx."
"The spacer increases the amount of medication delivered to the lungs."
"Inhale rapidly using the spacer with the MDI."
"Cover exhalation slots of the spacer with lips when inhaling."
The Correct Answer is B
A. This statement is incorrect; the spacer does not primarily increase medication delivery to the oropharynx.
B. The spacer helps to increase the amount of medication that reaches the lungs by allowing larger particles to settle out and preventing them from being deposited in the mouth and throat.
C. Inhaling slowly and deeply is recommended for effective medication delivery when using an MDI with a spacer.
D. Covering the exhalation slots would prevent proper airflow and could cause the child to inhale exhaled air, which is not recommended during inhalation.

Correct Answer is A
Explanation
A. A child with varicella (chickenpox) should return to school only after all the blisters have crusted over, indicating that the infectious stage has passed and they are no longer contagious.
B. Receiving the varicella vaccine does not apply to children who already have the infection; vaccination is preventive, not a treatment for those already infected.
C. Completing one week of antiviral medication is not a sufficient criterion for returning to school, as the child may still be contagious until all lesions are crusted.
D. Returning to school as soon as the rash appears is not safe, as the child is highly contagious during the initial rash stage and until all lesions have crusted.
Correct Answer is D
Explanation
A. Encouraging excessive rest and avoidance of physical activities can lead to feelings of inferiority by limiting opportunities for achievement and social interactions.
B. Limiting social interactions is counterproductive, as friendships and peer relationships are critical for social development during this stage.
C. While supervision is important, overly controlling the child’s activities can inhibit their ability to explore and learn, negatively impacting their sense of industry.
