Which patient problems are most commonly encountered by the health care team in the emergency department? Select all that apply

A. While fever is a common symptom, it is usually a secondary complaint or part of an underlying condition rather than a primary reason for emergency department (ED) visits. Patients with fever alone often seek primary care unless it is associated with severe infection or sepsis. B. Headaches are common in the general population, but only severe or acute-onset headaches are typical ED presentations. Routine or mild headaches are usually managed in outpatient settings. C. Poisonings, overdoses, and exposure to toxic substances are urgent issues that require immediate assessment and intervention in the ED. These cases frequently demand rapid evaluation, monitoring, and sometimes antidote administration. D. Chest pain is a common and critical complaint in the ED because it may indicate life-threatening conditions such as myocardial infarction, pulmonary embolism, or aortic dissection. It is prioritized for immediate assessment and intervention. E. Abdominal pain is one of the most frequent reasons for ED visits, ranging from minor issues to surgical emergencies such as appendicitis, bowel obstruction, or perforated ulcers. Prompt evaluation is essential to identify life-threatening conditions.
