Evaluate the following clinical scenarios of patients with suspected pulmonary embolism. What is the most appropriate next step in the diagnostic workup for each patient? Match each clinical presentation to its guideline-indicated diagnostic test.
- A 28-year-old woman is evaluated for sudden pleuritic chest pain; she is hemodynamically stable, her Wells score is 6.5 (high probability), and she has normal renal function.Computed tomography (CT) pulmonary angiography
- A 55-year-old man is assessed in the resuscitation bay for acute severe dyspnea; his blood pressure is 75/45 mm Hg, heart rate is 125/min, and he is deemed too unstable for safe transport.Bedside transthoracic echocardiography
- A 40-year-old woman is seen for atypical chest pain; her Wells score is 1.0 (low probability), heart rate is 88/min, oxygen saturation is 98%, and she has no history of exogenous estrogen use, prior thromboembolism, or recent surgery.No further diagnostic testing for pulmonary embolism
- A 71-year-old man is evaluated for acute dyspnea and tachycardia; his Wells score is 5.0 (moderate probability); laboratory results show an estimated glomerular filtration rate (eGFR) of 22 mL/min/1.73 m2, and his chest radiograph is clear.Ventilation-perfusion (V/Q) scan
Cevap
The correct pairings match each clinical vignette to its guideline-directed diagnostic step based on hemodynamic status, pre-test probability, and contraindications.
The correct pairings strictly align with established clinical guidelines for the diagnostic algorithm of pulmonary embolism, successfully balancing pre-test probability, hemodynamic stability, and patient-specific contraindications to medical imaging.
