ANES 6120/6121 – ANESTHESIA REVIEW AKB 1 – REVIEW QUESTIONS Professor Michael Nichols DIRECTIONS : Each of the numbered items or incomplete statements in this section is followed by answers or by completions of the statement. Select the ONE lettered answer or completion that is BEST in each case and fill in the circle containing the corresponding letter on the answer sheet. 1. An anesthesia machine is set to deliver oxygen 2 L/min, nitrous oxide 2 L/min, and enflurane. After 30 minutes of stable anesthesia, which of the following is the most likely cause of a decrease in the oxygen analyzer reading from 50% to 30%? (A) A leak in the ventilator bellows (B) Accumulation of water on the oxygen sensor membrane (C) Calibration at 100% oxygen using less than 100% oxygen (D) Disconnection of the wall oxygen hose (E) Presence of the oxygen analyzer in the expiratory limb 2. While delivering nitrous oxide 1.5 L/min, oxygen 1.5 L/min, and halothane 1%, a leak in the oxygen flowmeter will most likely be detected by the (A) low airway pressure alarm (B) “fail-safe” system (C) oxygen analyzer on the expiratory limb (D) oxygen flowmeter reading (E) mass spectrometric analysis of gases 3. During steady-state intraoperative controlled mechanical ventilation, exhaled tidal volume will be increased by (A) changing to more compliant tubing in the ventilatory circuit (B) increasing fresh gas flow in the anesthesia machine (C) increasing nitrous oxide concentration in the inspired mixture (D) increasing ventilatory rate (E) moving the volume sensor as far as possible from the patient 4. Proper handling of oxygen cylinders includes (A) maintenance of storage room temperature above 60 0 F (B) separate storage rooms for nitrous oxide and oxygen (C) opening the cylinder valve just sufficiently to register tank pressure accurately (D) storage in a room with conductive flooring (E) opening the cylinder valve briefly before attachment to the anesthesia machine

5. The pin index system (A) is not used in central pipeline connections (B) requires aligning four pins with four holes (C) is used on all sizes of medical gas cylinders (D) has been replaced by color coding of gas cylinders (E) prevents overfilling of gas cylinders 6.
