The nurse is caring for a client diagnosed with acute heart failure on the telemetry unit. Which laboratory result does the nurse know is most indicative of this diagnosis?

Hemoglobin 10.1 g/di (normal Female: 11.7-15.5 g/dL: Male: 14-17.3 g/dL

Brain natriuretic peptide 410 pg/mL (normal less than 100 pg/mL.)

Sodium 132 mEq/L (normal 135 - 145 mEq/L)

Fibrinogen level 201 mg/dL (normal 200-400 mg/dL)

Answer and Explanation

The Correct Answer is B

A.   A low hemoglobin level indicates anemia, not heart failure. While anemia can exacerbate heart failure, it is not the primary indicator.
B.   BNP is a biomarker that is elevated in response to heart failure. A level above 100 pg/mL is suggestive of heart failure, and 410 pg/mL indicates significant heart stress and likely acute heart failure.
C.   A low sodium level (hyponatremia) can occur in heart failure, but it is not specific enough to confirm the diagnosis. BNP is a more direct indicator of heart failure.
D.   This is a normal fibrinogen level and does not indicate heart failure. Fibrinogen is more associated with clotting disorders.

Correct Answer is B

Explanation

A. The pacemaker wire for a DDD device is placed in the right atrium and right ventricle, not the left ventricle.
B. This is the correct description of a DDD pacemaker, which has wires in both the right atrium and right ventricle to monitor and pace both chambers when needed.
C. This is incorrect because a DDD pacemaker does not pace both ventricles.
D. This is inaccurate because a DDD pacemaker does not fire with every heartbeat; it only fires when the heart’s natural electrical activity is insufficient.

A. Marked limitation with physical activity but comfortable at rest B. Angioedema and urticaria C. Increased urine output D. Chest pain during sleep that is relieved with nitroglycerin

Correct Answer is A

Explanation

A. Clients with left-sided heart failure often experience symptoms like shortness of breath, fatigue, and fluid retention, which limit physical activity. However, they may still feel relatively comfortable when resting.
B. These symptoms are more commonly associated with allergic reactions or side effects of medications (such as ACE inhibitors) rather than heart failure.
C. This is not typical in the later stages of left-sided heart failure. In fact, clients may experience reduced urine output due to poor kidney perfusion.
D. Chest pain can occur due to ischemia, but this is not a hallmark symptom of left-sided heart failure, which is more characterized by dyspnea and fatigue.
