A patient questions the use of lidocaine with epinephrine for repair of a laceration, stating, I thought that was the drug they use in intensive care for patients with heart trouble. Select the nurse's best response.
1. This drug comes in several forms. The form used to repair your laceration is designed to act locally.
2. Systemic absorption of lidocaine is promoted by epinephrine, so the anesthetic effects occur more quickly.
3. It's good you were alert to the events. A medication error occurred, and we will monitor the effects on your heart.
4. Epinephrine is absorbed more quickly than lidocaine, so the anesthetic effect wears off fast once the laceration is sutured.
Question 2

1. have low anesthetic potency.
2. require less drug to achieve immobility.
3. can be used alone to achieve surgical anesthesia.
