ANESTHESIA BOARD QUESTIONS &
ANSWERS
Bone marrow depression and peripheral neuropathy have been associated with
prolonged exposure to what anesthetic concentrations? - Correct Answers -nitrous
oxide
The potency of local anesthetics increases as the____? - Correct Answers -lipid
solubility increases
A decrease in cerebral blood flow is seen after the administration of what induction
agent? - Correct Answers -propofol
The age group with the highest minimum alveolar concentration (MAC) of desflurane is?
- Correct Answers -2 - 3 months
The two-to-three-months-of-age group represents the highest MAC requirement. MAC
subsequently decreases with advancing age.
The loss of ventricular filling as a result of acute atrial fibrillation is approximately: -
Correct Answers -15-25%
Passive flow accounts for about 75 - 85% of ventricular filling. The remaining 15 - 25%
occurs as a result of atrial contraction, which is lost during atrial fibrillation.
Topically applied ophthalmic medications are absorbed? Choose one..
- as quickly as intravenous administration
- more quickly than subcutaneous administration
- only minutely, with insignificant clinical effect
-directly into the central nervous system through the optic nerve foramen - Correct
Answers -more quickly than subcutaneous administration
-Topically applied ophthalmic medications are absorbed at a rate intermediate between
intravenous and subcutaneous injection. Children and the elderly are at particular risk
for the toxic effects of topically applied medications.
During pregnancy, the minimum alveolar concentration (MAC)? - Correct Answers -
decreases throughout the pregnancy
, The MAC progressively decreases during pregnancy, at term by as much as 40%. MAC
returns to normal by the third day after delivery.
Correct location of the catheter tip of a central venous line is in the? - Correct Answers -
superior vena cava
The CVP catheter tip should not be allowed to migrate into the heart chamber to avoid
arrhythmias and perforation.
Physiologic effects of electroconvulsive therapy (ECT) include an. - Correct Answers -
initial parasympathetic discharge followed by a sustained sympathetic response
An initial parasympathetic discharge followed by a sustained sympathetic response is
immediately seen after the induction of a seizure. Marked bradycardia with increased
secretions can occur, which is then followed by hypertension and tachycardia. Patients
scheduled for ECT are routinely given anticholinergic medication preoperatively
The effects of barbiturates on ischemic areas of the brain include? - Correct Answers -
redirection of blood flow to the ischemic areas
Barbiturates cause cerebral vasoconstriction in normal areas. These agents tend to
redistribute blood flow to ischemic areas in what is sometimes referred to as a reverse
steal phenomenon or Robin Hood effect. Ischemic areas remain maximally dilated and
unaffected by the barbiturate.
Venous irritation associated with the injection of diazepam and lorazepam is secondary
to? - Correct Answers -he presence of propylene glycol as a solvent
The insolubility of diazepam and lorazepam in water requires that parenteral
preparations contain propylene glycol, which has been associated with venous irritation.
In patients receiving vecuronium, the greatest augmentation of neuromuscular blockade
is seen with the use of what inhalation agent? - Correct Answers -desflurane
Volatile agents decrease the nondepolarizer dosage requirements. The degree of the
augmentation of blockade depends on the inhalational agent, with desflurane >
sevoflurane > isoflurane > nitrous oxide.
During hip replacement surgery, cardiopulmonary changes associated with the
application of acrylic bone cement include? - Correct Answers -hypotension secondary
to cement monomer absorption, hypoxemia secondary to air embolization, hypoxemia
secondary to fat embolization
Dextran 40 has been shown to improve microcirculation by? - Correct Answers -
decreasing blood viscosity
