Which of the following interventions is crucial in preventing ventilator-associated pneumonia (VAP) by reducing the bacterial load in the oral cavity?

A patient on mechanical ventilation is undergoing a weaning trial. Which parameter indicates the best readiness for successful weaning?

During a weaning trial, a patient exhibits a rapid-shallow breathing index (RSBI) of 110. What does this finding suggest?

A patient undergoing a spontaneous breathing trial (SBT) exhibits agitation, diaphoresis, and increased work of breathing. What is the most appropriate nursing intervention?

After extubation, a patient develops stridor and increased work of breathing. Which intervention should be implemented first?
