An obese, 70-year-old woman with a long history of tobacco abuse is awake and semirecumbent after uneventful anesthesia with isoflurane for a ventral hernia repair. During the first hour in the recovery room while breathing 50% oxygen by face mask, her arterial oxygen saturation decreases to 90% while other vital signs remain satisfactory. Which of the following is most likely to be effective in the management of this situation?

(A) Intravenous doxapram
(B) Racemic epinephrine by inhalation
(C) Continuous positive airway pressure by mask
(D) Reintubation of the trachea
(E) Coughing

BASIC Respiratory & Critical Care General

After removing the electrocautery pad from the thigh, a burn is noted at that site. Which of the following most likely contributed to this injury?

(A) A line-isolation monitor fault
(B) Current leak from the EKG module
(C) Defective grounding of the electrocautery unit
(D) Dried gel on the electrocautery pad
(E) Excessive current setting for cutting mode

BASIC Equipment & Physics

Which of the following statements about pulmonary function testing is true?

(A) Forced expiratory volume in one second (FEV1) is directly related to maximum voluntary ventilation
(B) FEV, is the most reliable indicator of small airways resistance
(C) Forced vital capacity is markedly decreased in obstructive lung disease with air-trapping
(D) Maximum mid-expiratory flow is less effort dependent than FEV1
(E) Three-second forced expiratory volume is the amount of air exhaled during the third second of exhalation

ADVANCED Respiratory & Critical Care
