Consider the following scenario: a student has prepared a series of analytical solutions to be run on an instrument in another room. the student has worn gloves throughout the preparation of the solutions, and has wiped up all drips and spills that occurred during that process. the student removes her gloves before leaving the lab room and carries her solutions in scintillation vials in a large clean beaker to the room where the instrument is located. once in the new room, the student obtains a new pair of gloves before dispensing the solutions for analysis. which of the following changes could improve the student's procedure? (check all that apply.)
a. the student could have worn a single glove on the hand she used for transporting the solutions to the instrument room, and used her non-gloved hand for opening doors and pushing elevator buttons. correctb. the student could have worked with her lab partner so that one of them could carry the materials with gloved hands, while the other opened doors and pressed elevator buttons with non-gloved hands. correctc. the student could have chosen a plastic bin, or other less breakable container to carry her solutions to the instrument so that she wasn't carrying glassware with her bare hands.
