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
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 A
Explanation
A. Cheyne-Stokes respirations: Cheyne-Stokes respirations are characterized by alternating periods of hyperventilation followed by apnea. This respiratory pattern is often observed in clients with conditions affecting the central nervous system, such as brain injury or stroke.
B. Apneustic respirations: Apneustic respirations are characterized by prolonged, gasping inhalations followed by extremely short, ineffective exhalations. This pattern is associated with damage to the pons, a part of the brainstem.
C. Stridor: Stridor is a high-pitched, noisy breathing sound caused by turbulent airflow through a partially obstructed airway. It is not related to the described alternating pattern of hyperventilation and apnea.
D. Kussmaul respirations: Kussmaul respirations are deep, rapid respirations often seen in metabolic acidosis. They are not characterized by the alternating pattern described in the scenario.
Correct Answer is A
Explanation
A. Smoking cessation: Chronic bronchitis is often associated with smoking and exposure to tobacco smoke. The most effective preventive measure for chronic bronchitis is to quit smoking and avoid exposure to secondhand smoke. Smoking cessation not only prevents chronic bronchitis but also improves overall respiratory health.
B. Regular moderate exercise: While regular exercise is beneficial for overall health, it is not specifically cited as a primary preventive measure for chronic bronchitis. However, exercise can contribute to overall respiratory health and well-being.
C. Maintenance of ideal weight: Maintaining an ideal weight is important for overall health, but it is not identified as a specific preventive measure for chronic bronchitis.
D. Annual influenza immunization: Influenza immunization is important for preventing influenza (flu) and its complications. While individuals with chronic bronchitis may be at increased risk for respiratory infections, annual influenza immunization is not a direct preventive measure for chronic bronchitis itself.
