Topical anesthesia is used on the skin or:

• inner ear

• hair

• mucous membranes

• subarachnoid space

The most widely used volatile anesthetics are sevoflurane and:

• desflurane

• nitrous oxide

• isoflurane

• halothane

Anesthesia that affects a single nerve, a deep plexus, or a network of nerves is known as:

• local infiltration anesthesia

• field block anesthesia

• spinal anesthesia

• subarachnoid anesthesia

Because general anesthetics affect the CNS, patients may feel:

• normal immediately after awakening from anesthesia

• overly alert and excited after anesthesia

• drowsy, weak, or tired for as long as a few days after having general anesthesia

• drowsy, weak, or tired for up to 24 hours after having general anesthesia

The action of local anesthetics is:

• systemic

• different based on the patient's weight

• based on diurnal rhythms

• dose-dependent

Adverse effects of local anesthetics include all the following except:

• light-headedness

• dizziness

• slurred speech

• temporary loss of hearing

The type of anesthesia that is popular for labor and delivery and is very slowly absorbed into the cerebrospinal fluid is known as:

• topical anesthesia

• epidural anesthesia

• local infiltration anesthesia

• field block anesthesia

All the following are indications for the use of local anesthesia except:

• drainage of abscesses

• biopsies

• to produce surgical anesthesia

• vasectomy

In the 1840s, the introduction of the first three surgical anesthetics occurred. These agents were nitrous oxide, chloroform, and:

• ester

• ether

• chlorphyll

• ammonium dioxide

Loss of sensation or consciousness is defined as:

• anesthetic accident

• surgical anesthesia

• analgesia

• anesthesia
