As you are about to administer an injection, your needle tip inadvertently touches the patient's disposable bib (clean but not sterile). What should you do next?

Recap the needle with the one-hand scoop method, discard it and replace it with a new, sterilized needle. Proceed in administering the local anesthesia

Why is it important to slowly deposit the anesthetic solution?

Slowly depositing improves patient comfort and prevents tissue damage.

True

When administering local anesthesia, the bevel of the needle should face the bone.

True

Which division of the trigeminal nerve carries both afferent and efferent nerves?

V3
