  2. Sublingual
  3. Oral
  4. Transdermal

ANS: B

Since oral drugs enter the liver through the hepatic portal system, many undergo the first-pass effect, which means they may be altered or nearly inactivated when passing through the liver, potentially reducing the drug’s effectiveness.

  4. Because the local anesthetic could not reach the site of action
  5. Because the local anesthetic could not bind to proteins

ANS: C

When a local anesthetic is injected into an infected wound, the local becomes ionized and cannot enter the lipid membrane of the nerves to reach the site of action. See Insight 1-3.
