Yes, that was going to be my suggestion, a "brain". You can create one with times on it, a place for patients room number and name, then circle the times they will have meds due, mark thru it when completed. Also, have a place to write any PRNs you may administer. Mix or spike, and prime tubing on IV antibiotics before you enter the patients room. It should not be the duty of the other nurses to "ambush" as you stated, they should make the charge nurse aware of this, and a good charge nurse will teach you, not reprimand you. Also, working you first job in CVICU is a little heavy to start out.
