A nurse is caring for a client who is cyanotic and has a respiratory rate of 8/min with shallow respirations. Which of the following is the priority action by the nurse?

A) Check the client's pulse rate: While it is important to assess vital signs, the priority in this scenario is ensuring that the client’s airway is open and that they can breathe adequately. A pulse rate check can be performed after addressing the immediate respiratory needs. B) Administer oxygen to the client: Administering oxygen is important for clients who are cyanotic and showing signs of respiratory distress. However, oxygen will not be effective if the airway is obstructed. The first priority is to ensure that the airway is open and clear, as this is the most immediate need for breathing. C) Establish a patent airway for the client: The most immediate priority is to ensure that the client has a patent airway. Cyanosis and a decreased respiratory rate with shallow respirations indicate that the client is likely unable to get enough oxygen, possibly due to an obstruction or inadequate airway. Once the airway is secured, other interventions such as administering oxygen can follow. D) Place a pulse oximeter on the client's finger: While measuring oxygen saturation is important, the priority action is to ensure that the client’s airway is open first. If the client is cyanotic and showing signs of respiratory distress, the nurse must address the airway immediately before assessing the pulse oximeter reading, as it may not provide accurate data without a patent airway.
