A nurse is reinforcing teaching with the guardian of a school-age child who has asthma.Which of the following instructions should the nurse include in the teaching?

Choice A reason: Obtaining a pneumococcal immunization is an important preventive measure for children with asthma, as respiratory infections can exacerbate their condition. Choice B reason: Encouraging physical activity is important for children with asthma. While some precautions may be necessary, avoiding participation in school sports altogether is not recommended. Choice C reason: Having the child inhale deeply and quickly when using the peak flow meter is not the recommended technique. The child should take a deep breath and exhale forcefully to obtain an accurate reading. Choice D reason: Salmeterol is a long-acting beta-agonist (LABA) used for maintenance therapy, not for managing acute exacerbations. It should be used in combination with an inhaled corticosteroid for optimal asthma control.
