Ans. should be A because heroin causes coma, miosis and cyanosis. However uticaria is also a symptom of opiods but it is felt at lower doses. In this question the person has overdose which means more than 30 mg of heroin. opiods act on u-receptors and cause CNS depression which leads to coma. CNS depression also causes respiratory depression which may lead to cyanosis and hypoxia. BP stays stable for a while but then drops at which point the pt goes into shock and vascular damage ensues. TX overdose with naloxone diluted to 0.4 mg IV slowly until patient's arousal improves.
