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 C

Explanation

A. “I probably will not have any transfusion reactions from my own blood.” - Autologous transfusions
generally have a lower risk of transfusion reactions because they involve the client’s own blood.
B. “This is the blood I’ve been giving for the past 6 weeks for myself.” - This is a correct understanding of the process of autologous blood donation, where the client donates blood for their own use.
C. An autologous blood transfusion involves the collection and storage of a patient's own blood for later transfusion. This significantly reduces the risk of bloodborne infections, such as hepatitis, HIV, and other blood-borne diseases, as the blood is coming from the patient themselves.
D. “Since I have O negative blood, it’s a good thing I’m getting my own blood.” - The client may not need additional teaching here because O negative blood is universally compatible, but the reason they are getting their own blood is due to the autologous donation process, not because of blood type.

A. Cyanosis B. Petechiae C. Epistaxis D. Hematuria

Correct Answer is A

Explanation

A. Cyanosis, or a bluish discoloration of the skin, occurs when there is insufficient oxygen in the blood, which can result from decreased perfusion due to clotting in DIC. It is a sign of poor oxygenation and perfusion.
B. While petechiae (small red or purple spots) are a common manifestation of DIC due to microvascular clotting and bleeding, they are not a sign of decreased perfusion.
C. Epistaxis (nosebleeds) is another bleeding manifestation of DIC but is not indicative of decreased perfusion, which is more closely related to cyanosis.
D. Hematuria (blood in the urine) can occur in DIC due to clotting in the kidneys or urinary tract. However, it is more related to bleeding than to decreased perfusion.
