1. Which medication produces dissociative anesthesia?
Propofol (Diprivan)
Lidocaine (Xylocaine)
Fentanyl (Sublimaze)
Ketamine (Ketalar) - ANSWER Ketamine (Ketalar)
Justification
Ketamine is an NMDA-receptor-blocking medication producing a functional
dissociation between the thalamocortical and limbic systems, a state that has
been termed dissociative anesthesia. It produces dose-dependent CNS depression
characterized by profound analgesia and amnesia by depressing neuronal
function in the cerebral cortex and thalamus, while simultaneously activating the
limbic system.
2. Which temperature monitor location MOST accurately correlates with adult
core body temperature?
Rectum
,Forehead
Distal esophagus
Axilla - ANSWER Distal esophagus
Justification
The gold standard for temperature monitoring is blood from the pulmonary
artery, which correlates well with the tympanic membrane, distal esophagus, and
nasopharyngeal sites. Rectal temperature lags behind other sites, and the
forehead temperature must be adjusted by adding 2°C.
3. Which practices DECREASE the risk of a fire during laser surgery?
(Select 2.)
Open-air administration of supplemental oxygen
Administration of <30% fraction of inspired oxygen
Use of a polyvinyl chloride endotracheal tube
Inflation of endotracheal tube cuff with saline and dye - ANSWER
Administration of <30% fraction of inspired oxygen
Inflation of endotracheal tube cuff with saline and dye
Justification
During laser surgery it is recommended that open-air administration of oxygen be
avoided. Administration of <30% oxygen decreases the risk of airway fire. During
laser airway surgery, laser-resistant endotracheal tubes should be used and the
cuff inflated with saline. Dye (such as methylene blue) should be added because
this will allow earlier recognition of cuff rupture.
,4. Where is the proper placement of Magill forceps on the endotracheal tube for
nasal intubation?
On the connector
On the cuff
Distal to the cuff
Proximal to the cuff - ANSWER Proximal to the cuff
Justification
The Magill forceps should be placed proximal to the cuff to prevent tearing of the
cuff and aid in the placement of the endotracheal tube.
5. A 0.5-mL dose of a 1:1,000 solution of epinephrine contains how many
milligrams of epinephrine?
0.1
0.5
1
5 - ANSWER 0.5
Justification
In a 1:1,000 solution, there is 1 g in 1,000 mL of solution; 1 g is 1,000 mg;
therefore, 1,000 mg in 1,000 mL is 1 mg per 1 mL, or 0.5 mg of epinephrine in 0.5
mL of a 1:1,000 solution.
, 6. A 65-year-old man is admitted for altered mental status, pulse oximeter
desaturations to the low 90s, blood in the airway, and increased work of
breathing. Past medical history includes recent chemotherapy and radiation
exposure for head and neck carcinoma. Intubation by anesthesia personnel is
requested secondary to severe mucositis. Which is the MOST important
consideration for airway management?
Cervical spine laxity
Loss of skeletal muscle tone
Reduced need for sedatives
Increased risk for aspiration - ANSWER Increased risk for aspiration
Justification
Mucositis is a painful inflammation and ulceration of the mucous membranes of
the digestive tract. Oral mucositis is a relatively common adverse effect of high-
dose chemotherapy and radiation to the head and neck. Oral lesions begin as
mucosal whitening followed by the development of erythema and tissue friability.
Narcotics are frequently required to achieve adequate analgesia. In its most
severe form, pseudomembrane formation, edema, and bleeding may cause
airway compromise or risk of aspiration.
7. Which inhaled agent forms a haloalkene compound that is toxic to the
kidneys?
