A nurse is reviewing the laboratory values of a client who is at risk for disseminated intravascular coagulopathy. Which of the following values should the nurse report to the provider?

Platelets 156,000/mm³

Fibrinogen 85 mg/dL

PT 12 seconds

PTT 64 seconds

Answer and Explanation

The Correct Answer is B

A. Platelets 156,000/mm³: This platelet count is within the normal range (normal range: 150,000 to 400,000/mm³). Although disseminated intravascular coagulopathy (DIC) can lead to thrombocytopenia (low platelet count), the platelet count in this scenario is not indicative of DIC.

B. Fibrinogen 85 mg/dL: This is the correct answer. A decreased fibrinogen level is often seen in DIC. Fibrinogen is consumed in the formation of microclots, and a low level may indicate ongoing coagulation.

C. PT 12 seconds: The prothrombin time (PT) is within the normal range. In DIC, the PT may be prolonged due to the consumption of clotting factors, but in this case, the PT is normal.

D. PTT 64 seconds: The partial thromboplastin time (PTT) is prolonged, which can be an indication of DIC. However, the more specific indicator in this scenario is the low fibrinogen level.

Correct Answer is D

Explanation

A. Troponin is a lipid whose levels reflect the risk for coronary artery disease: This statement is incorrect. Troponin is not a lipid, and its levels do not reflect the risk for coronary artery disease. Troponin is a protein associated with muscle tissue.

B. Troponin is an enzyme that indicates damage to brain, heart, and skeletal muscle tissues: While troponin indicates damage to muscle tissues, it is specifically associated with cardiac muscle, not brain or skeletal muscle tissues.

C. Troponin is a protein that helps transport oxygen throughout the body: This statement is incorrect. While proteins in the blood may contribute to oxygen transport, troponin's primary role is in muscle contraction, particularly in the heart.

D. Troponin is a heart muscle protein that appears in the bloodstream when there is damage to the heart: This is the correct answer. Troponin is a protein found in cardiac muscle cells, and when there is damage to the heart, such as during a myocardial infarction, troponin is released into the bloodstream. Elevated troponin levels in the blood are indicative of myocardial injury or infarction.

A. "I will take my diuretic before sleep and drink fluids during the day. B. I plan to slow down if I am tired the day after exercising." C. "I will read food labels and limit my sodium to 4 grams per day." D. "I should use naproxen to manage discomfort."

Correct Answer is B

Explanation

Correct answer: B

A. "I will take my diuretic before sleep and drink fluids during the day": This statement is not correct. Diuretics are usually taken in the morning to avoid disrupting sleep with increased urination at night. Additionally, fluid intake is generally restricted in congestive heart failure to manage fluid balance.

B. "I plan to slow down if I am tired the day after exercising":This statement reflects an understanding of the need to manage activity levels and recognize the signs of overexertion, which is crucial for clients with congestive heart failure. Pacing activities and allowing for adequate rest can help prevent exacerbations of heart failure symptoms.

C. "I will read food labels and limit my sodium to 4 grams per day": This is incorrect. Limiting sodium intake is a key component of heart failure management. The recommended sodium intake for individuals with heart failure is often much lower than 4 grams per day, typically around 2 grams or less.

D. "I should use naproxen to manage discomfort": Using nonsteroidal anti-inflammatory drugs (NSAIDs) like naproxen can contribute to fluid retention and worsen heart failure symptoms. This statement is not indicative of effective teaching.
