In this scenario, the nurse has just assessed for the presence of normal rise and fall of the chest with respirations after performing CPR on a client who experienced cardiac arrest. The next action should be based on the immediate needs of the client following this assessment. 1. **Assessing the Situation**: After CPR, if the nurse has confirmed that there is no normal rise and fall of the chest, it indicates that the client is still not breathing adequately or at all. Therefore, the priority is to ensure that the client receives adequate oxygenation. 2. **Evaluating the Options**: - **Move the client into a side-lying position**: This is not appropriate immediately after CPR, as the client may still require resuscitation efforts. - **Place a cooling blanket on the client**: This is typically done later in the management of post-cardiac arrest care, particularly if the client is being treated for hypothermia or to prevent neurological damage. - **Administer the highest available oxygen concentration**: This is critical to ensure that the client receives adequate oxygenation, especially if they are not breathing effectively. - **Remove the automated external defibrillator (AED) electrodes**: This should not be done until it is confirmed that the client is stable and does not require further defibrillation. 3. **Conclusion**: The most appropriate next action for the nurse is to **administer the highest available oxygen concentration** to the client to ensure they receive adequate oxygenation. Therefore, the correct answer is: **Administer the highest available oxygen concentration.**
