Explanation:

• First question: Examination gloves are for protecting hands from specimens or chemicals. Touching a microscope (which may have been in contact with specimens) or a cell phone (which is a personal item not related to the lab task and can carry contaminants) while wearing exam gloves can lead to cross - contamination. For example, if the gloves have chemical residues, they can transfer to the phone or microscope in an improper way. So the statement is false.
• Second question:
• a. wear exam gloves and safety glasses: Gloves protect hands from caustic chemicals or biological specimens (in dissection), and safety glasses protect the eyes from splashes (in chemical handling) or debris (in dissection).
• b. wash their hands and retrieve their cell phones: Washing hands is a good practice but not during the active handling of specimens or caustic chemicals. Retrieving cell phones is not relevant to the task and can cause contamination (as explained above).
• c. always wear lab coat: A lab coat provides a barrier between the student's clothes and the hazardous materials (chemicals or biological substances in dissection).
• d. proceed on their own: In a lab setting with caustic chemicals or during dissection (which may require some techniques), students should not proceed on their own as there are safety protocols and techniques that need to be followed (e.g., proper use of dissection tools, handling of chemicals).

Answer:

• First question: B. False
• Second question: A. wear exam gloves and safety glasses, C. always wear lab coat
