The nurse is caring for a client who has signs and symptoms of heart failure. Which of the following diagnostic tests is appropriate to assess the patient’s heart failure?
International normalized ratio (INR)
Brain natriuric peptide (BNP)
Troponin
Creatinine
The Correct Answer is B
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.

Correct Answer is A
Explanation
A. "A single elevated blood pressure does not confirm hypertension. A diagnosis of hypertension requires two or more elevated readings taken by your physician before a diagnosis can be made."
This response emphasizes the need for multiple elevated readings for a diagnosis of hypertension. It educates the individual about the diagnostic criteria and encourages them to seek further evaluation from their physician.
B. "We will need to reevaluate your blood pressure because your age places you at high risk for hypertension."
This response might be seen as implying that age alone is a significant factor in determining hypertension, which may not be accurate. While age is a risk factor, the emphasis should be on the need for multiple readings and a physician's evaluation rather than attributing it solely to age.
C. "Hypertension is prevalent among men: it is fortunate we caught this during your routine examination."
This response suggests that the elevated blood pressure is automatically assumed to be hypertension based on gender. It is important to avoid making assumptions and instead focus on the need for proper evaluation and multiple readings for a hypertension diagnosis.
D. "You have no need to worry. Your pressure is probably elevated because you are being tested."
This response dismisses the individual's concerns and attributes the elevated blood pressure solely to the testing situation. While stress or anxiety can influence blood pressure readings, it's essential to address the need for further evaluation and not completely disregard the possibility of hypertension.
