After administering nitroglycerin spray to a client experiencing angina, which action should the nurse implement next?

A. Compress the client's nares: Compressing the nares is a technique used for nasal medication administration or controlling nosebleeds, not for sublingual or oral spray forms of nitroglycerin. This action is unrelated to nitroglycerin use for angina.B. Observe for facial flushing: Facial flushing is a common side effect of nitroglycerin due to vasodilation. While it should be noted during monitoring, it is not the immediate next action after administration when addressing angina symptoms.C. Advise the client to rest: Resting after nitroglycerin administration reduces myocardial oxygen demand, helping to relieve anginal pain more effectively. It also helps prevent hypotension and dizziness, which are common side effects of the medication.D. Elevate the client's feet: Elevating the feet is typically done if hypotension occurs. It is not a standard next step immediately after giving nitroglycerin unless the client shows symptoms like syncope or significant blood pressure drops.
