A client with congestive heart failure presents with a dry, persistent cough. The nurse should recognize this symptom as:

A) This choice is incorrect because taking digoxin with a high-fat meal is not necessary. Digoxin can be taken with or without food, but consistent administration is essential for optimal therapeutic effects.

B) This choice is incorrect because skipping a dose of digoxin can lead to suboptimal medication levels and reduced effectiveness. If the client experiences nausea or vomiting, they should contact their healthcare provider for guidance.

C) This choice is correct. Digoxin is used to treat congestive heart failure and other cardiac conditions. It is crucial for clients to monitor their blood pressure regularly, especially if their healthcare provider has instructed them to adjust the medication dose based on their blood pressure readings.

D) This choice is incorrect because while avoiding certain over-the-counter medications is essential while on digoxin due to potential drug interactions, it is not the primary instruction for the client. The client should discuss any new medications, including over-the-counter drugs, with their healthcare provider to ensure they are safe to take with digoxin.

A) This choice is incorrect because hemoptysis refers to coughing up blood from the respiratory tract, which is not described by the client.

B) This choice is incorrect because dyspnea refers to difficulty breathing or shortness of breath, not a dry, persistent cough.

C) This choice is incorrect because paroxysmal nocturnal dyspnea is characterized by sudden breathlessness that awakens the client from sleep, not a dry cough.

D) This choice is correct. Cardiac asthma is a form of wheezing or coughing that occurs as a result of fluid accumulation in the lungs due to congestive heart failure. It is not caused by asthma but is a manifestation of heart failure impacting the respiratory system.
