A nurse is reviewing a client's new prescription for nitroglycerin 0.4 mg SL every 3 to 5 min PRN for chest pain. The nurse should instruct the client to do which of the following?

A. Drink 8 oz of water with the medication.: Sublingual (SL) medications dissolve under the tongue and do not require water. Drinking water may interfere with proper absorption of the medication. B. Chew the medication thoroughly.: Chewing alters the intended sublingual route, delaying absorption and reducing the rapid onset of action needed during chest pain episodes. C. Place the medication under the tongue.: Sublingual nitroglycerin works quickly by dissolving under the tongue and being absorbed directly into the bloodstream, relieving chest pain within minutes. D. Take the medication with food.: Food is not required for SL nitroglycerin. Taking it with food can interfere with the speed and effectiveness of the medication’s action.
