A nurse is caring for a client who has an endotracheal tube (ET) and is on mechanical ventilation. Which of the following actions should the nurse take for a ventilator alarm due to an increase in peak airway pressure? (Select all that apply)

Choice A reason: Suctioning the ET removes secretions obstructing airflow, increasing peak airway pressure. Mucus buildup narrows the airway, triggering alarms. Clearing secretions restores patency, reduces pressure, and prevents complications like atelectasis or hypoxia, critical for effective ventilation in mechanically ventilated clients. Choice B reason: Verifying ET placement ensures the tube is in the trachea. Misplacement, like esophageal intubation, increases airway resistance, elevating peak pressure. Confirmation via capnography or X-ray prevents hypoxia, ensuring proper ventilation and safety in clients on mechanical ventilators. Choice C reason: Checking for kinks in ventilator tubing addresses mechanical obstructions raising peak airway pressure. Kinks restrict airflow, triggering alarms. Straightening tubing restores normal gas delivery, reducing resistance and maintaining effective ventilation, preventing hypoxia in mechanically ventilated clients. Choice D reason: Administering a bronchodilator relieves bronchospasm, a common cause of high peak airway pressure. Bronchoconstriction narrows airways, increasing resistance. Bronchodilators relax smooth muscles, improving airflow and reducing pressure, addressing reversible causes like asthma in ventilated clients. Choice E reason: Increasing tidal volume exacerbates high peak airway pressure, risking barotrauma or lung injury by forcing air against resistance. Addressing underlying causes like secretions or bronchospasm is safer, as higher volumes do not resolve the root issue, potentially worsening outcomes.
