A 65-year-old patient with hypertrophic cardiomyopathy has chest pain prior to induction of anesthesia. Pulse is 80 bpm and blood pressure is 130/80 mmHg. The ECG (V5) shows sinus rhythm and new ST-segment depression. The most appropriate management is administration of

A 52-year-old woman undergoes facial surgery during general endotracheal anesthesia. The ventilator is set to deliver a tidal volume of 600 ml and a respiratory rate of 10/min at an FiO2 of 1.0. SpO2 is 100%, peak inspiratory pressure is 18 cmH2O, and PetCO2 is 40 mmHg. The surgeon flexes the patient's head so the chin touches the chest. Which of the following findings indicates that endobronchial intubation has NOT occurred?
- (A) Fluctuating capnographic waveform
- (B) Greater expiratory volume than inspiratory volume
- (C) Unchanged SpO2
- (D) Unchanged PetCO2
- (E) Unchanged peak inspiratory pressure
Which of the following findings is most likely in an 85-kg 30-year-old man who is breathing spontaneously through 6-mm endotracheal tube?
- (A) Decreased PetCO2
- (B) Decreased SpO2
- (C) Increased minute ventilation
- (D) Increased respiratory rate
- (E) Increased tidal volume

- (B) be of slower onset
- (C) be less reliable
- (D) produce less change in heart rate
- (E) require more anticholinergic
