Which of the following conditions might warrant medical attention for an arrestee?

The condition that warrants medical attention for an arrestee is the inability to stand or walk. This can indicate a serious underlying medical issue that requires immediate assessment and treatment. It may be the result of various concerns, such as a neurological condition, injury, or intoxication, all of which can pose risks to the individual's safety and wellbeing in a detention setting. An arrestee unable to stand or walk may also be in a critical state that could deteriorate without prompt medical intervention.

Other conditions listed, while they may indicate the need for medical attention in certain contexts, do not typically require urgent care in the same way. For example, while obesity can contribute to health problems, it is not an immediate risk requiring intervention. Minor cuts and bruises generally are not threats to an individual's health unless they are severe or infected. Disorientation can be concerning but may not indicate an immediate need for medical assistance unless accompanied by other serious symptoms such as confusion or altered mental status. Therefore, the inability to stand or walk directly signals a need for urgent medical evaluation.
