A nurse is providing discharge instructions to a client who developed deep-vein thrombosis (DVT) postoperatively and is prescribed anticoagulant therapy. Which of the following instructions should the nurse include?

A. Maintaining a semi-Fowler's position as often as possible: While maintaining an elevated position can assist with breathing, it may not directly address the issue of tenacious bronchial secretions. Adequate hydration and other measures are often more effective.

B. Encouraging the client to drink 2 to 3 L of water daily: This is the correct answer. Adequate hydration helps to thin mucus, making it easier to clear from the airways. Drinking 2 to 3 liters of water daily is a helpful strategy to promote hydration and reduce the viscosity of bronchial secretions.

C. Helping the client select a low-salt diet: While a low-salt diet may have cardiovascular benefits, it is not a primary intervention for addressing tenacious bronchial secretions. Hydration and airway clearance techniques are more directly relevant.

D. Administering oxygen via nasal cannula at 2 L/min: While oxygen therapy may be necessary in COPD, it is not the primary intervention for managing tenacious bronchial secretions. Hydration and other measures aimed at thinning mucus are more appropriate.

A. "The medication can take up to 15 minutes to take effect." - This statement is not accurate, sublingual nitroglycerin works rapidly and often provides relief within a few minutes.

B. Sublingual nitroglycerin is administered by placing the tablet under the tongue, and it should be allowed to dissolve or be absorbed directly into the bloodstream through the mucous membranes. It is not swallowed or chewed. The small sip of water can help facilitate the dissolving process.

C. "Avoid taking the medication prior to exercising." - This statement is not accurate. Nitroglycerin can be taken before anticipated exertion or activities that may trigger angina to prevent anginal episodes during physical activity.

D. "Stop taking the medication and notify your provider if you develop a headache." - While headaches are a common side effect of nitroglycerin, they are generally transient and not a reason to stop taking the medication. Persistent or severe headaches should be reported to the healthcare provider.
