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. 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.

A. "The test will provide a detailed profile of the heart’s electrical activity."

This statement is inappropriate because transesophageal echocardiography (TEE) primarily provides detailed images of the heart's structure, such as the valves and chambers, rather than focusing on the heart's electrical activity. The assessment of electrical activity is typically associated with electrocardiography (ECG or EKG) rather than echocardiography.

B. "I will need to start an IV in your arm before the test."

This statement is appropriate. It is common for medical procedures, including TEE, to require an intravenous (IV) line for administration of medications or fluids during or after the procedure.

C. "Your throat may be a little sore after the exam."

This statement is appropriate. TEE involves inserting a probe through the esophagus, and it is common for patients to experience a sore throat afterward due to the presence of the probe.

D. "You will need to refrain from eating and drinking 6-8 hours before this test."

This statement is appropriate. It is standard practice to ask patients to fast for a specific period before TEE to minimize the risk of complications, such as aspiration, during the procedure.
