A patient unable to extend the leg or flex the hip is MOST likely to have incurred an injury in which nerve plexus?

You are working with a candidate OEC Technician who is practicing the application of splints. When checking the sling and swathe that the candidate applied to an upper extremity, you note that it is not applied correctly. You point this out to the candidate and tell him that the purpose of a sling and swathe is to:

a. hold an injured arm up so that the patient doesn't need to support it. b. prevent further movement of an injured extremity. c. hold a wooden splint in place. d. prevent the patient from using an injured arm when getting into a toboggan.

You connect an intubated patient to an air-entrainment nebulizer system through a T tube set at 60% with an input flow of 15 L/min. Toward the middle of inspiration, you observe that mist stops exiting from the open end of the T tube

What does this indicate? a. Flow is adequate to meet patient needs. b. Patient has a low inspiratory flow rate. c. Flowmeter must be calibrated. d. Patient is not receiving 60% O2.
