Anesthesia Board Questions With Complete Solutions
The Bourbon pressure gauge can be used to calculate the cylinder volume for
(Select 2 ).
A- Nitrogen
B- Helium
C- Nitrous oxide
D- Carbon Dioxide Right Ans - A- Nitrogen
B= Helium
Both exist as a liquid.
Changes found in banked blood include: (Select 2)
A- increased levels of 2,3-DPG
B - a left shift of the hemoglobin dissociation curve
C- decreased levels of potassium
D- formation of microaggregates
E- alkalosis secondary to the presence of citrate
F- increased intracellular ATP stores
G- thrombocytosis Right Ans - B,D
Changes occurring in banked blood include:
Depletion of 2,3-DPG
Depletion of intracellular ATP
Oxidative damage
Increased adhesion to vascular endothelium
Altered cell morphology
Accumulation of microaggregates
Hyperkalemia (as high as 17.2 mEq/L)
Absence of platelets (after 2 days of storage)
Hemolysis
Accumulation of proinflammatory products
Does "light" anesthesia promote wheezing? Right Ans - Yes, if patint has a
reactive airway.
The largest fraction of carbon dioxide in the blood is in the form of :
,A - carbamino compounds
B- Bicarbonate
C- Dissolved gas
D- Carboxyhemoglobin Right Ans - B
Pulmonary changes associated with Duchenne's muscular dystrophy include:
A-a restrictive ventilatory defect
B-an obstructive ventilatory defect
C-decreased pulmonary artery pressures
D- increased residual volume Right Ans - A- restrictive ventilatory defect
The combination of marked kyphoscoliosis and degeneration of the
respiratory muscles produces a severe restrictive ventilatory defect in
patients with Duchenne's muscular dystrophy. Pulmonary hypertension is
also commonly seen.
A 46-year-old male is scheduled for an emergent laparotomy for small bowel
obstruction. His history is complicated by the acute onset of hepatitis B four
days earlier and he presents with significant scleral jaundice. The
perioperative mortality in this patient is approximately:
A-2%
B- 5%
C- 10%
D- 25% Right Ans - C- 10%
Patients with acute hepatitis should have elective surgery postponed until the
acute hepatitis has resolved. Studies indicate increased perioperative
morbidity (12%) and mortality (10% with laparotomy) during acute hepatitis.
An increase in intraocular pressure has been associated with: (select 3)
A-nitrous oxide administration
B-succinylcholine administration
C-opioid administration
D-hyperventilation
E- laryngoscopy
F- hypoxemia
, G-sevoflurane administration Right Ans - B, E, F
succinylcholine, laryngoscopy, hypoxemia.
Succinylcholine increases intraocular pressure by 5 - 10 mm Hg for 5 - 10
minutes after administration. This increase is primarily the result of
prolonged contracture of the extraocular muscles from the depolarizing
effects of succinylcholine. Nitrous oxide, volatile anesthetic agents and opioids
have been associated with a reduction in intraocular pressure. Hypoxemia,
hypercarbia, hypertension, hypervolemia, laryngoscopy and intubation have
all been shown to increase IOP.
In the pressure-volume loop below, cardiac work is best represented by:
A-the area of the curve
B-the slope of the line from points C to D
C-the distance of the line from points C to D
D-the slope of a line from points A to D Right Ans - A-the area of the curve
Cardiac work is the product of pressure and volume and is linearly related to
myocardial oxygen consumption. Cardiac work is best represented by the area
of the curve of a pressure-volume loop.
Current anesthesia apparatus checkout recommendations suggest which of
the following prior to every case?
A-Check oxygen cylinder supply
B-Check the carbon dioxide absorber
C-Performance of a machine low-pressure leak test
D-Calibration of the oxygen monitor Right Ans - B- Check the carbon
dioxide absorber
Verification of the adequacy of the carbon dioxide absorber is suggested prior
to every case. If the same anesthesia machine is being used by the same
provider, E-cylinder pressure checks, machine low-pressure leak testing and
calibration of the oxygen sensor need not be repeated after an initial check.
A patient with diabetic ketoacidosis is scheduled for an emergent laparotomy.
Which of the following best explains the decrease in serum potassium
concentration that occurs in this patient following administration of insulin?
, A-Dilutional hypokalemia follows free water retention from decreased
osmotic diuresis
B-Extracellular potassium is actively transported with glucose into cells
C-Insulin enhances renal excretion of potassium
D-Intracellular potassium is exchanged for extracellular glucose Right Ans -
B-Extracellular potassium is actively transported with glucose into cells
Which two leads of the electrocardiogram provide a sensitivity of 80% for the
detection of myocardial ischemia?
a. Leads I and II
b. Leads I and V5
c. Leads II and V5
d. Leads II and V3
e. None of the above Right Ans - c. Leads II and V5
All of the following patients should have a cardiology consult prior to non-
cardiac surgery except:
A. Unstable angina
B. Atrial fibrillation with ventricular rate of 105
C. Mild tricuspid regurgitation
D. New-onset heart failure Right Ans - C. Mild tricuspid regurgitation
Pick 2 of the following which do NOT cause SPÓ artifact.
1) fetal Hgb
2) bilirubin
