After suctioning for fifteen seconds and retrieving thick yellow secretions, the appropriate next step is to re-oxygenate the client. This action is crucial because suctioning can lead to temporary hypoxia due to the removal of air along with secretions from the airways. By re-oxygenating the client, the nurse helps to ensure that the patient maintains adequate oxygen levels, promoting respiratory stability and comfort.

Suctioning can stimulate the vagus nerve and cause bradycardia, so it may also have an immediate effect on the patient's heart rate and oxygen saturation levels. Re-oxygenation helps counteract these effects and supports recovery after an intervention that can cause irritation and distress in the airway.

Ensuring the patient's oxygen saturation is at a safe level allows the nurse to assess the effectiveness of the previous suctioning and prepare for any further interventions if necessary. By prioritizing re-oxygenation after suctioning, the nurse promotes the patient's overall well-being and minimizes risks associated with airway management.
