A) Stable vital signs and ABGs
B) Pulse oximetry above 80% and stable vital signs
C) Stable nutritional status and ABGs
D) Normal orientation and level of consciousness
Ans: A
Feedback:
Among many other predictors, stable vital signs and ABGs are important predictors of successful weaning. Pulse oximetry must greatly exceed 80%. Nutritional status is important, but vital signs and ABGs are even more significant. Patients who are weaned may or may not have full level of consciousness.
