Write answer in between .Q:While at the emergency room, a 43-year-old woman starts experiencing progressive chest pain, shortness of breath, dizziness, palpitations, bilateral arm numbness, and a feeling that she is choking. She originally came to the hospital after receiving the news that her husband was injured in a car accident. The symptoms began 5 minutes ago. The patient has had two episodes involving similar symptoms in the past month. In both cases, symptoms resolved after approximately 10 minutes with no sequelae. She has no history of serious illness. Her father had a myocardial infarction at the age of 60 years. She is allergic to amoxicillin, cats, and pollen. She is 170 cm 5 ft 7 in tall and weighs 52 kg 115 lb; BMI is 18 kgm2. She appears distressed and is diaphoretic. Physical examination shows no other abnormalities. 12-lead ECG shows sinus tachycardia with a shortened QT interval and an isoelectric ST segment. Urine toxicology screening is negative. Which of the following is the most appropriate next step in management?? A: Order D-dimers, B: Order thyroid function tests, C: Order echocardiogram, D: Administer nebulized albuterol, E: Administer clonazepam,  <response>: This is a clinical vignette describing a 43-year-old woman presenting with acute onset chest pain, shortness of breath, dizziness, palpitations, arm numbness, and a choking sensation. She has a family history of myocardial infarction and is experiencing emotional distress after learning her husband was in a car accident. Her symptoms are consistent with a panic attack, likely triggered by the stressful news about her husband. Key findings include normal ECG except for sinus tachycardia and shortened QT, negative urine drug screen, no past medical history except similar self-limited episodes, and lack of any abnormalities on physical exam. The most appropriate next step is to administer an anxiolytic medication such as clonazepam to treat her symptoms of anxietypanic attack. Thyroid function tests and echocardiogram are not indicated given lack of supporting history or exam findings. D-dimers would be reasonable if pulmonary embolism was suspected, but there is no evidence to suggest this based on the vignette. Nebulized albuterol may help if she was experiencing bronchospasm, but this is not described.E: Administer clonazepam
