ARRT Patient Care Practice Exam

A patient showing a decreased level of consciousness may indicate:

1. hyperglycemia

2. anxiety attack

3. heart attack

4. stroke

The correct answer is: stroke

A decreased level of consciousness can be a critical indicator of neurological conditions, with stroke being one of the most significant causes. When a stroke occurs, it can result in reduced blood flow and oxygen to the brain, leading to impaired function and altered consciousness levels. This symptom may manifest in various forms, including confusion, disorientation, or an outright inability to respond. The urgency in recognizing stroke symptoms, including decreased consciousness, is paramount, as prompt medical intervention can significantly affect outcomes and recovery. While other conditions like hyperglycemia, anxiety attacks, and heart attacks may also affect a patient's overall state, they are less commonly associated with a direct and sudden decrease in consciousness compared to a stroke. Hyperglycemia primarily leads to symptoms like excessive thirst and urination, fatigue, or confusion, but is not as immediate in impact as a stroke. Anxiety attacks typically present as heightened anxiety and panic rather than decreased consciousness. Heart attacks can cause various symptoms, including chest pain and shortness of breath, but they do not typically lead to a sudden drop in consciousness unless there is severe cardiac compromise. Thus, a decreased level of consciousness strongly correlates with potential neurological emergencies, making stroke the most likely condition indicated by this symptom.
