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?

Choice A reason: Tiotropium is a long-acting anticholinergic bronchodilator administered once daily via a handihaler device. The statement reflects correct understanding of the medication’s purpose and administration schedule. Choice B reason: Tiotropium does not directly thin secretions. Its primary action is bronchodilation by blocking muscarinic receptors, which reduces bronchospasm. Expecting thinner sputum indicates a misunderstanding of the drug’s mechanism. Choice C reason: While clients may use short-acting inhalers for breakthrough symptoms, tiotropium is not intended for intermittent use. This statement shows partial understanding but does not correctly describe tiotropium’s role. Choice D reason: Tiotropium is not a rescue medication. It has a slow onset and is used for maintenance therapy. Using it for sudden shortness of breath would be ineffective and unsafe. Rescue inhalers such as albuterol are appropriate for acute symptoms.
