A nurse is assessing a client who is receiving mechanical ventilation. Which of the following actions should the nurse take if the high-pressure alarm sounds?

The correct answer is B: Check for kinks in the tubing. When the high-pressure alarm sounds during mechanical ventilation, it indicates an obstruction in the breathing circuit. Checking for kinks in the tubing ensures the client is receiving adequate ventilation. Administering a bronchodilator (A) is not indicated for a high-pressure alarm. Increasing the tidal volume (C) may worsen the obstruction. Suctioning the airway immediately (D) is not the initial action for a high-pressure alarm.
