After patiently waiting for the tube to fill, both she and the preceptor were relieved to get finished. Almost immediately after returning to the laboratory and processing the sample, they were sent back to redraw the electrolytes because the potassium value was too high. Before leaving, the preceptor grabbed more BC equipment because he knew that the BCs would have to be redrawn also. and lytes on a patient in the ICU were ordered, the preceptor quickly grabbed the student and they headed for the floor. It was clear after looking at the patient that they would have to use a butterfly in a hand vein to collect the test specimens. The preceptor was busy belping the student prepare the site and, while setting out all of the equipment needed, he did not pay close attention to the order in which the media bottles were placed. The student was elated that she was able to access the difficult vein and that blood was flowing feely into the anaerobic bottle. After filling both it and the aerobic bottle to the proper level, she proceeded to draw an SST for electrolytes from the same site. The Di0od flow was now very slow, with blood entering QUESTIONS 1.
