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. Place a pulse oximeter on the client's finger. While assessing oxygen saturation is important, it is not the priority in this situation. The client is cyanotic with a respiratory rate of 8/min and shallow respirations, indicating severe respiratory compromise. Immediate intervention is needed before assessing oxygen saturation. B. Administer oxygen to the client. Providing oxygen is appropriate, but it will not be effective if the client's airway is obstructed or if their respirations are inadequate. Oxygen delivery is only useful when there is a patent airway and effective ventilation. C. Check the client's pulse rate. Assessing circulation is important, but the priority in this situation is ensuring an open airway to allow for adequate oxygenation. The client's respiratory status suggests that they may not be effectively exchanging oxygen, which must be addressed immediately. D. Establish a patent airway for the client. The priority action is to ensure a patent airway, as compromised respirations can lead to respiratory failure and cardiac arrest. Airway management, such as repositioning the head, using airway adjuncts, or preparing for assisted ventilation, takes precedence over other interventions to ensure oxygen delivery.
