Final answer:
Point-of-care testing (POCT) is performed at a patient's bedside for immediate results. In this case, further diagnostic tests and aspirin therapy are recommended based on the patient's symptoms and potential risk of embolus.
Step-by-step explanation:
Testing done at the patient's bedside is known as point-of-care testing (POCT). This type of testing allows for immediate results and is useful for making quick decisions about patient care. In the scenario provided, the patient demonstrates symptoms that suggest a problem with the sensory systems, indicating that further diagnostic tests such as a CT scan may be required. Additionally, since there is concern about a possible embolus, the patient is put on aspirin therapy to prevent blood clots. Other tests like breath tests, detection of antibodies in blood, and immunochromatographic assays could be used to assess different health conditions at the point of care.
