When a Counselor Communicates with a Client Using E-Mail

When a counselor communicates with a client using e-mail:

A) the counselor should never include anything that is confidential because it is unethical to do so.
B) the client's business e-mail address should never be used because employers often read the e-mail messages of their employees.
C) the client should be told to avoid using e-mail to set or change appointment times because it is impossible to tell whether the counselor received the message that was sent.
D) the client should be advised that e-mail messages can always be retrieved and that e-mail systems are not as secure as other means of communication.
E) the counselor should never print out the e-mail messages because the client's confidentiality would be compromised by the existence of paper copies.
