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. "Increasing my intake of foods containing trans-fatty acids can lower my risk." B. "Adding foods containing omega-3 fatty acids to my diet can lower my risk." C. "A weight loss program can decrease my LDL cholesterol level." D. "Exercising regularly will increase HDL cholesterol levels."

Correct Answer is A

Explanation

A. "Increasing my intake of foods containing trans-fatty acids can lower my risk." - This statement is incorrect. Trans-fatty acids are associated with an increased risk of cardiovascular disease. The client should be advised to reduce or eliminate the consumption of foods containing trans fats.

B. "Adding foods containing omega-3 fatty acids to my diet can lower my risk." - This statement is correct. Omega-3 fatty acids, found in fish and certain plant sources, have been associated with a decreased risk of cardiovascular disease.

C. "A weight loss program can decrease my LDL cholesterol level." - This statement is correct. Weight loss, especially in the context of a healthy diet and regular exercise, can contribute to a decrease in LDL (low-density lipoprotein) cholesterol levels.

D. "Exercising regularly will increase HDL cholesterol levels." - This statement is correct. Regular exercise is associated with an increase in HDL (high-density lipoprotein) cholesterol, which is considered beneficial for heart health.
