Final answer:
To investigate serious conditions, medical professionals may order tests such as blood tests, X-rays, CT scans, and endoscopy, depending on the suspected illness. Neurological exams, EEG, and auscultation are also useful diagnostic tools. Treatment varies based on the diagnosis, from medications to surgery.
Step-by-step explanation:
When a patient has alarm signs or symptoms indicating a serious condition, a medical professional may order a variety of tests and investigations to further assess the patient's health. Commonly, these may include blood tests, X-rays, CT scans, endoscopy, and depending on the condition, other specialized exams such as electroencephalography (EEG) or hearing an assessment of heart sounds through auscultation.
For instance, in cases of suspected neurological issues like stroke or seizures, medical professionals may perform neurological exams assessing sensory and motor functions or use diagnostic imaging like CT scans to detect bleeding or obstructions in the brain. In other circumstances, where cardiovascular problems are suspected, auscultating heart sounds using a stethoscope can be an effective initial diagnostic technique. If an infectious disease is suspected based on the presentation, lab tests to identify the causative agent might be ordered. To treat conditions, a variety of approaches may be necessary.
