What are some conditions that might warrant medical attention for an arrestee?

Medical attention for an arrestee is crucial in various scenarios, particularly when there are significant health indicators present. High blood pressure can be indicative of serious underlying health issues, such as hypertension or heart problems, and should be monitored to prevent potential emergencies. Excessive bleeding, regardless of its cause, signals a potentially life-threatening situation that requires immediate medical attention to prevent further complications such as shock or blood loss. Extreme body temperature, whether it's hyperthermia or hypothermia, poses serious risks and can lead to critical health outcomes if not addressed promptly.

The other options do not encompass the breadth of conditions that necessitate medical evaluation in an arrestee. Extreme mental distress, while important, represents only one facet of health concerns that might require medical intervention. Minor injuries and bruises typically do not demand immediate medical care unless they are indicative of a more significant issue. Finally, not all legal complaints filed warrant medical attention; medical evaluations are based on physical health conditions rather than the legal status of an individual. Therefore, option A includes critical physical health concerns that clearly justify medical attention for someone in custody.
