A nurse is suctioning the airway of a client who is receiving mechanical ventilation via an endotracheal tube. Which of the following findings should the nurse identify as an indication that the suctioning has been effective?

Choice A reason While thinning of secretions can be a positive sign, it's not always visible. A decrease in peak inspiratory pressure is a more objective indicator of improved airway patency. Choice B reason. Peak inspiratory pressure is the maximum pressure required to push air into the lungs. If suctioning is effective, it will remove secretions and reduce airway resistance, leading to a decrease in peak inspiratory pressure. Choice C reason: While a productive cough can indicate that secretions are being moved, it doesn't directly measure the effectiveness of suctioning. Choice D reason: Flattening of the artificial airway cuff: Flattening of the artificial airway cuff is not a relevant indicator of the effectiveness of suctioning. The cuff of an endotracheal tube is inflated to prevent air leaks around the tube and to maintain proper ventilation. It is not directly related to the effectiveness of suctioning.
