Question

when you are injured in the laboratory, you should first
a. visit the school nurse
b. see a doctor after school
c. tell the teacher
d. apply first aid yourself

Explanation:

In a laboratory, safety protocol dictates that the first - step after an injury is to inform the teacher. The teacher can then assess the situation and decide on the appropriate next steps, such as getting medical help or providing first - aid. Visiting the school nurse or seeing a doctor after school may not be immediate enough, and applying first - aid oneself without teacher knowledge may not be the best course if the injury is more serious than it appears.

Answer:

c. Tell the teacher
