The patient with decreased LOC and muffled heart sounds after a head-on MVA is exhibiting signs of cardiac tamponade secondary to bleeding into the pericardium caused by trauma. This patient will experience circulatory collapse if not treated immediately. The patient with subcostal retractions and lip edema after eating an apple is experiencing an allergic reaction. This patient requires prompt care but being able to speak indicates the patient’s airway edema is not advanced yet. The patient with a gunshot wound to the right shoulder requires care but the patient is coherent enough to report tingling and shooting pains, so this patient can wait. The patient with SLE who has dyspnea with an x-ray that shows a normal-sized heart and pulmonary edema likely has acute mitral regurgitation. This patient’s condition is not as dire as the patient with cardiac tamponade.
