the administration of a bronchodilator shows an increase in FEV1 from 60% to 80% of predicted.

complete airway obstruction Correct Answer: During capnography monitoring of a

patient off full ventilatory support using the CPAP protocol with 40% O2. Early in the initial

accessory muscles while breathing. Which of the following would be your first action at this

increase the suction pressure to -120 mm Hg Correct Answer: While using a Yankauer device to
suction an adult patient, you are unable to remove thick secretions. The regulator attached to the

oropharyngeal suctioning device displays a reading of -70 mm Hg. Which of the following
sh
actions should you take at this time?
