How will excess condensate present in aerosol tubing affect the delivered FiO2? a)It will increase the FiO2. b)It will decrease the FiO2. c)It will only affect the FiO2 if in excess of 2 mL. d)It will produce an unpredictable effect on the FiO2. correct answer: a)It will increase the FiO2. You are caring for a 6-year old patient who is receiving positive-pressure mechanical ventilation via an endotracheal tube. The child begins to move his head and suddenly becomes cyanotic, and his heart rate decreases. His SpO2 is 65%. You remove the child from the mechanical ventilator and begin to provide manual ventilation with a bag via the endotracheal tube. During manual ventilation with 100% oxygen, the child's color and heart rate improve slightly and his blood pressure remains adequate on the right side and are present but consistently diminished on the left side. The trachea is not deviated, and the neck veins are not distended. A suction catheter passes easily beyond the tip of the endotrachael tube. Which of the following is the most likely cause of this child's acute deterioration? A)Equipment failure B)Tracheal tube obstruction C)Tension pneumothorax on the right side D)Tracheal tube displacement into the right main bronchus correct answer: D)Tracheal tube displacement into the right main bronchus You are assisting with an elective intubation of an average sized 11 year old child in respiratory failure. A colleague is retrieving the color-coded length based tape from the resuscitation cart. Which of the following is likely to be the estimated size of the cuffed endotracheal tube for this child? A)4.0 B)5.5 C)6.0 D)7.5 correct answer: C)6.0 Which of the following complications of CPAP can develop when an infant experiences inadvertent positive end-expiratory pressure (PEEP) from gas trapping resulting from tachypnea? a)Pulmonary hypertension b)Pneumothorax
