What physiological response is expected during an upper overdose?

The physiological response expected during an upper overdose, which refers to the use of stimulants such as cocaine, amphetamines, or other similar drugs, includes an increased body temperature. Stimulants can significantly elevate metabolic activity and increase sympathomimetic effects, leading to hyperthermia. The body’s increased metabolic rate, combined with heightened energy levels and agitation, can contribute to this rise in temperature.

In contrast, other responses like decreased heart rate or respiration are not typical in stimulant overdoses; stimulants generally cause an increase in heart rate and respiratory rates due to their activating effects on the central nervous system. Increased lethargy is also not associated with stimulant overdoses because these substances typically induce wakefulness and energy rather than drowsiness or lethargy. Thus, the correct response highlighting increased body temperature aligns with the expected physiological effects of an upper overdose.
