Answer

Phase I (early stimulation) is as follows:

  • CNS findings - Mydriasis, headache, bruxism, nausea, vomiting, vertigo, nonintentional tremor (eg, twitching of small muscles, especially facial and finger), tics, preconvulsive movements, and pseudohallucinations (eg, cocaine bugs)

  • Circulatory findings - Possible increase in BP, slowed or increased pulse rate (possibly with ventricular ectopy), and pallor

  • Respiratory findings - Increase in rate and depth

  • Temperature findings - Elevated body temperature

  • Behavioral findings - Euphoria, elation, garrulous talk, agitation, apprehension, excitation, restlessness, verbalization of impending doom, and emotional lability
