ensure that each pass lasts no longer than 5 seconds for

which puts the patient at increased risk for respiratory
failure.
,during patient transport you should Correct Answer NOT

Answer Observing the six rights of medication
administration.
What can the nurse do to evaluate a patient's response to
continuous oxygen therapy delivered at 4 L/min by nasal
cannula? Correct Answer Regularly measure and trend
the patient's pulse oximetry (SpO2) values.
