A nurse cares for a group of clients with respiratory conditions. Which client should the nurse see first?

Choice A reason: A pneumothorax represents a life-threatening emergency where air enters the pleural space, causing lung collapse. Absent lung sounds indicate significant collapse that can lead to a tension pneumothorax, causing mediastinal shift and hemodynamic collapse. This client requires immediate assessment for potential chest tube insertion or needle decompression. Choice B reason: This client is stable and preparing for discharge. Requesting an inhaler refill is a routine pharmaceutical need that does not involve acute physiological distress. While important for long-term management, it is the lowest priority when compared to clients with active, acute respiratory or infectious pathologies. Choice C reason: Patients with emphysema often require low-flow oxygen to maintain saturations between 88% and 92%. A flow rate of 2 L/min is a standard therapeutic intervention for this chronic condition. As long as the client is not in acute distress, they are considered stable and secondary to emergencies. Choice D reason: While pneumonia is a serious condition, the client has already begun receiving intravenous antibiotics, which is the definitive treatment. This client is currently being managed and monitored, making them more stable than a client with an acute lung collapse and potential for rapid deterioration.
