The nurse is caring for a client who has heart failure and a history of asthma. The nurse reviews the provider's orders and recognizes that clarification is needed for which of the following medications?

A. Isosorbide dinitrate is a nitrate that helps to dilate blood vessels and reduce the workload on the heart. It is generally safe for clients with asthma. B. Carvedilol is a beta-blocker used to manage heart failure, but it can also cause bronchoconstriction, which is dangerous for clients with asthma. Beta-blockers can exacerbate asthma symptoms, so clarification is needed before administration. C. Fluticasone is a corticosteroid commonly used to manage asthma and other respiratory conditions; it is not contraindicated for this client. D. Captopril is an ACE inhibitor used to treat heart failure and does not pose a risk for clients with asthma.
