While running in a parking lot, a young boy tripped and fell. he hit his face and mouth on a curb, knocking one of his top front teeth from its socket. bleeding has been controlled and the tooth found. which instructions would you give your partner when caring for the tooth?

Rinse the tooth first then put it in a cup of saline for transport.

Explanation:

With our current medical development we are able to perform a tooth re-implanting procedure  , in which a dentist will put the knocked out tooth back to the initial position.

Putting the tooth in a saline will prevent bacteria from accumulating in the tooth. Not doing this before replanting the tooth could potentially cause a more severe infection in your mouth.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
