A nurse is providing education to a client diagnosed with congestive heart failure. The client asks, "What are the most common causes of CHF?" How should the nurse respond?

"CHF is primarily caused by infections and viral illnesses."

"The leading causes of CHF are hypertension and coronary artery disease."

"CHF is often a result of excessive physical exertion and overworking the heart."

"The main cause of CHF is anemia and low red blood cell count."

Answer and Explanation

The Correct Answer is B

A) This choice is incorrect because while infections and viral illnesses can contribute to heart failure in some cases, they are not the leading causes of CHF. Hypertension and coronary artery disease are more common risk factors.

B) This choice is correct. Hypertension (high blood pressure) and coronary artery disease (narrowing or blockage of the heart's blood vessels) are the leading causes of CHF. Both conditions place increased stress on the heart and can lead to heart muscle damage and failure.

C) This choice is incorrect because while excessive physical exertion and overworking the heart can contribute to heart failure, they are not the primary causes of CHF. Underlying conditions like hypertension and coronary artery disease are more significant risk factors.

D) This choice is incorrect because anemia and low red blood cell count can impact heart function, but they are not the main causes of CHF. Hypertension and coronary artery disease are more commonly associated with the development of CHF.

Correct Answer is C

Explanation

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. Wheezing on auscultation B. Hyperactive bowel sounds C. Absence of jugular vein distention D. Crackles on auscultation

Correct Answer is D

Explanation

A) This choice is incorrect because wheezing on auscultation is a characteristic finding in respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), not congestive heart failure.

B) This choice is incorrect because hyperactive bowel sounds are not specific to congestive heart failure and are more indicative of gastrointestinal activity.

C) This choice is incorrect because the absence of jugular vein distention is not directly related to fluid accumulation in the lungs. Jugular vein distention is associated with right-sided heart failure.

D) This choice is correct. Crackles, also known as rales, are abnormal lung sounds heard on auscultation and may indicate fluid accumulation in the lungs, a common symptom of congestive heart failure. The presence of crackles suggests pulmonary congestion due to fluid leaking into the alveoli.
