A client with heart failure is placed on a low sodium diet. Which statement by the client indicates that the nurse’s nutritional teaching plan has been effective?

A. Intake and output:

Intake and output refer to monitoring the amount of fluids a person consumes (intake) and eliminates (output) through urine, feces, and other means. While tracking fluid intake and output is important, it may not provide a direct indication of excess fluid retention.

B. Pitting pedal edema:

Pitting pedal edema is swelling in the lower extremities, particularly the ankles and feet, that leaves an indentation (pit) when pressure is applied. This can be a sign of fluid retention but may not always be the earliest or most reliable indicator.

C. Crackles in the bases of the lungs:

Crackles or rales in the bases of the lungs can be indicative of pulmonary congestion, which may occur due to fluid accumulation. However, crackles alone may not always be specific to fluid overload and can be present in other respiratory conditions.

D. Daily weights:

Daily weights are a critical and sensitive measure for assessing fluid balance. Sudden weight gain, especially over a short period, can be a strong indicator of fluid retention. Monitoring weight on a daily basis helps to detect changes early, allowing for prompt intervention.

A. International normalized ratio (INR):

INR is a test used to monitor the effectiveness of anticoagulant therapy, particularly drugs like warfarin. It measures the time it takes for blood to clot. It's not directly related to assessing heart failure but is more associated with monitoring anticoagulation status.

B. Brain natriuretic peptide (BNP):

BNP is a peptide released by the heart in response to increased pressure and volume in the heart, often seen in heart failure. Elevated BNP levels can indicate the presence of heart failure. It's a useful diagnostic marker for heart failure.

C. Troponin:

Troponin is a protein released into the blood when there is damage to the heart muscle, usually during a heart attack. It is not specific to heart failure but is commonly used to diagnose myocardial infarction (heart attack).

D. Creatinine:

Creatinine is a waste product that comes from the normal wear and tear on muscles. While elevated creatinine levels can be seen in conditions affecting kidney function, it's not a direct marker for assessing heart failure. However, kidney function is often evaluated in conjunction with heart failure assessments.
