病重的病人通常头脑都不是很清醒。。。怎么翻译

Heavily ill people usually are not so clear in mind, the only thing they want to do is relieving pain, so sometimes they make unreasonable decisions.

heavily sick man usually does not have a clear mind and thinking, only thing on their mind is to assuage their pain, thus they would make unwise decision in many cases.

Patients in severe diseases rarely have clear minds. What they want only is to alleviate their agony, so sometimes they don't draw reasonable decisions.
