40-year-old unresponsive patient who fell from a ladder.

In a healthy patient, the oxygen saturation should be at least ________ when breathing room air.

95%

Once the pressure in an oxygen cylinder has been regulated to about 50 pounds per square inch (psi):

a flowmeter is then used to deliver the appropriate oxygen rate

Which of the following statements regarding pulse oximetry is correct?

Pulse oximetry should not replace a thorough patient assessment

Quickly visualize her chest for obvious movement while assessing for a carotid pulse.

The appropriate landmark for performing abdominal thrusts on a conscious patient with a severe airway obstruction is:

above the naval and below the xiphoid process.
