| directives, advance medical | Advance directives preserve the person's right to accept or reject a course of medical treatment even after that person becomes mentally or physically incapacitated to the point of being unable to communicate those wishes. There ared two basic types of advance directives: (1) a living will, in which the person outlines specific treatment guidelines that are to be followed by health care providers; (2) a health care proxy (also called a power of attorney for health-care decision-making) in which the person designates a trusted individual to make medical decisions in the event that he or she becomes too incapacitated to make such decisions. Advance directive requirements vary greatly from one jurisdiction to another and should therefore be drawn up in consultation with an attorney who is familiar with the laws of the particular jurisdiction. (This entry is based upon material from the National MS Society). (12 Dec 1998) |
| directly | 1. In a direct manner; in a straight line or course. "To run directly on." "Indirectly and directly too Thou hast contrived against the very life Of the defendant." (Shak) 2.

"No man hath hitherto been so impious as plainly and directly to condemn prayer." (Hooker) 4. Exactly; just. "Stand you directly in Antonius' way." (Shak) 5. Straightforwardly; honestly. "I have dealt most directly in thy affair." (Shak) 6. Manifestly; openly. "Desdemona is directly in love with him." (Shak) 7. Straightway; next in order; without delay; immediately. "Will she go now to bed?' Directly.'" 8. Immediately after; as soon as. "Directly he stopped, the coffin was removed."

Synonym: Immediately, forthwith, straightway, instantly, instantaneously, soon, promptly, openly, expressly. Directly, Immediately, Instantly, Instantaneously. Directly denotes, without any delay or diversion of attention; immediately implies, without any interposition of other occupation; instantly implies, without any intervention of time. Hence, "I will do it directly," means, "I will go straightway about it." "I will do it immediately," means, "I will do it as the very next thing." "I will do it instantly," allows not a particle of delay. Instantaneously, like instantly, marks an interval too small to be appreciable, but commonly relates to physical causes; as, the powder touched by fire instantaneously exploded.
