Objectives: After studying the article entitled “Evaluation of the Diagnostic Value of Bedside Transthoracic Ultrasonography (TTUS) and Lower Extremity Three-Points Compression Duplex in the Diagnosis of the Pulmonary Embolism,” you will be able to:
Understand the use of point-of-care ultrasound to help diagnose pulmonary embolism (PE)
Define Wells’s deep vein thrombosis criteria (WDVTC)
Explain how point-of-care ultrasound and WDVTC can be used in clinically suspected PE cases
Which sonographic examinations were completed to assist in the diagnosis of PE? Three-point lower extremity, bilateral lung, and heart Full lower extremity and bilateral lung Three-point lower extremity, right lung, and heart Full lower extremity, bilateral lung, and heart
Which Wells’s criterion was replaced with “venous ultrasound positive findings for DVT”? Alternative diagnosis less likely than PE Diagnosis less likely for PE by lung and heart TTUS Signs and symptoms of DVT Heart rate >100 beats/min
What is the sensitivity measurement for the modified Wells’s criteria in the researchers’ study? 46.15 80.00 94.87 48.72
What were the findings of the research study? PE diagnosis was more accurate with the integration of lung, heart, and lower limb ultrasound. There was no effect on PE diagnosis when point-of-care ultrasound was included. Wells’s criteria were more effective at predicting PE diagnosis than WDVTCs. D-dimer could be used alone to help predict PE.
Which D-dimer level was considered a positive result? >200 µg/L >500 µg/L >700 µg/L >300 µg/L
Which sonographic finding would correlate with a highly considered PE? Slight pleural effusion Subpleural lesion less than 5 mm in size One typical lesion with slight adjacent pleural effusion Two or more characteristic triangular or rounded pleural lesions
Which areas of the lower leg were evaluated for deep vein thrombosis? Femoral, saphenofemoral junction, and popliteal vein Common femoral, deep femoral, and popliteal vein Iliac, saphenofemoral junction, and posterior tibial vein Saphenofemoral junction, deep femoral, and posterior tibial vein
