(Questions 1 through 90): Each question or incomplete statement in this section is
followed by answers or by completions of the statement, respectively. Select the ONE
BEST answer or completion for each item.
1. A 75-year-old patient in the intensive care unit (ICU) is extubated after
recovering from acute respiratory distress syndrome (ARDS). He has a history
of previous myocardial infarction, congestive heart failure, and pneumonia. He
has an A-line, pulmonary artery (PA) catheter and is receiving oxygen by nasal
cannula. Which of the following techniques is LEAST accurate for assessing
an intravascular fluid challenge?
A. Central venous pressure (CVP)
B. PA occlusion pressure
C. Transesophageal echocardiography (TEE)
D. Measurement of pulse pressure variation (PPV)
2. Select the correct statement regarding color Doppler imaging.
A. It is a form of M-mode echocardiography
B. The technology is based on continuous wave Doppler
C. By convention, motion toward the ultrasound probe is red and
motion away from the probe is blue
D. Two ultrasound crystals are used: one for transmission of the
ultrasound signal and one for reception of the returning wave
3. When the pressure gauge on a size “E” compressed-gas cylinder containing N2
O begins to fall from its previous constant pressure of 750 psi, approximately
how many liters of gas will remain in the cylinder?
A. 200 L
B. 400 L
C. 600 L
D. Cannot be calculated
4. What percent desflurane is present in the vaporizing chamber of a desflurane
vaporizer (pressurized to 1500 mm Hg and heated to 23° C)?
A. Nearly 100%
B. 85%
C. 65%
D. 45%
, 5. If the internal diameter of an intravenous catheter were doubled, flow through
the catheter would be
A. Decreased by a factor of 2
B. Decreased by a factor of 4
C. Increased by a factor of 8
D. Increased by a factor of 16
6. A size “E” compressed-gas cylinder completely filled with N2 O contains how
many liters?
A. 1160 L
B. 1470 L
C. 1590 L
D. 1640 L
7. Which of the following methods can be used to detect all leaks in the low-
pressure circuit of all contemporary anesthesia machines?
A. Negative-pressure leak test
B. Common gas outlet occlusion test
C. Traditional positive-pressure leak test
D. None of the above
8. Which of the following valves prevents transfilling between compressed-gas
cylinders?
A. Fail-safe valve
B. Check valve
C. Pressure-sensor shutoff valve
D. Adjustable pressure-limiting valve
9. The driving force of the ventilator (Datex-Ohmeda 7000, 7810, 7100, and
7900) on the anesthesia workstation is accomplished with
A. Compressed oxygen
B. Compressed air
C. Electricity alone
D. Electricity and compressed oxygen
10. The pressure gauge on a size “E” compressed-gas cylinder containing O2 reads
1600 psi. How long could O2 be delivered from this cylinder at a rate of 2
L/min?
A. 90 minutes
B. 140 minutes
C. 250 minutes
D. 320 minutes
11. A 25-year-old healthy patient is anesthetized for a femoral hernia repair.
Anesthesia is maintained with isoflurane and N2 O 50% in O2 , and the
patient’s lungs are mechanically ventilated. Suddenly, the “low-arterial
saturation” warning signal on the pulse oximeter gives an alarm. After the
patient is disconnected from the anesthesia machine, he undergoes ventilation
