A client diagnosed with chronic obstructive pulmonary disease (COPD) is given a new prescription for tiotropium via an inhalation device. Which statement indicates that the client understands the instructions for using this medication?

A. When I cough up sputum, the secretions should be less thick: Tiotropium is a long-acting anticholinergic bronchodilator that works by relaxing airway smooth muscles to improve airflow. It does not directly thin or alter the viscosity of mucus, so improvement in sputum thickness is not the expected outcome of this medication. B. I should use this medication in its inhaler every day: Tiotropium is intended for daily, long-term maintenance therapy in COPD to prevent bronchoconstriction and improve airflow. Consistent daily use helps maintain bronchodilation and reduce the frequency of exacerbations. Understanding that it is not for acute symptom relief demonstrates appropriate patient comprehension. C. If I have sudden shortness of breath, I will use this inhaler: Tiotropium is not a rescue inhaler. Acute episodes of dyspnea require a short-acting bronchodilator such as albuterol. Using tiotropium for sudden symptoms would be ineffective and could delay appropriate treatment for acute airway obstruction. D. I will use my other inhaler in between uses: Combining other inhalers with tiotropium should be done according to the healthcare provider’s instructions. Misuse or unsupervised use “in between” doses may lead to inappropriate medication timing, reduced efficacy, or adverse effects.
