What should the nurse teach a client who is being discharged with the sublingual nitroglycerin? Select 4 that apply

A. Take the medication 5 minutes after the pain has started: Sublingual nitroglycerin should be taken immediately at the onset of chest pain, not delayed. Waiting 5 minutes may allow ischemia to worsen. Rapid administration can prevent further myocardial injury. B. Stop taking the medication if a tingling sensation under the tongue is present: A tingling sensation under the tongue is a common and expected effect of sublingual nitroglycerin and indicates that the tablet is dissolving properly. This does not warrant stopping the medication. C. Teach the client not to take erectile dysfunction medications while taking nitrates: Nitrates and phosphodiesterase inhibitors (e.g., sildenafil) together can cause life-threatening hypotension. Clients should be cautioned against using both medications concurrently. D. Avoid abrupt changes in posture when taking nitroglycerin: Nitroglycerin causes vasodilation, which may result in orthostatic hypotension. Clients should rise slowly and sit or lie down after taking the medication to reduce the risk of falls. E. Take acetaminophen if a headache occurs while taking this medication: Headaches are a common side effect of nitroglycerin due to vasodilation. Acetaminophen is recommended for relief, as it’s generally well-tolerated. F. Store medication in the original bottle and protect from light and heat: Nitroglycerin is sensitive to light, heat, and moisture. To preserve potency, it must be kept in its original amber glass container with the lid tightly closed.
