EMT Medical Conditions Practice Exam

A transient ischemic attack is the right description. It’s a brief interruption of blood flow to part of the brain that causes stroke-like signs—such as weakness, numbness, speech trouble, or vision changes—but those signs go away completely and there is no lasting brain injury. The key idea is the focal neurological deficit caused by temporary ischemia that resolves, unlike a full stroke where deficits persist or worsen because brain tissue has been damaged. In EMS terms, this is a warning symptom that a stroke could occur soon, so you treat it as a stroke for rapid transport and evaluation. Check the time symptoms started, ensure airway and breathing are okay, monitor glucose, and get the patient to a stroke center promptly. The other options describe events that are not a transient ischemic event causing a brief focal deficit. A seizure or epilepsy involves abnormal electrical activity and often includes convulsions or a postictal state, not a pure, transient focal deficit that resolves without lasting effects. A generalized seizure affects the whole body and consciousness, which doesn’t fit the described stroke-like, focal, fully reversible signs.
