A progressive care unit nurse is responding to a client with a history of Graves' disease who has abruptly developed severe delirium, a temperature of (), and a heart rate of 178 beats per minute. Determine the priority sequence in which the nurse should implement the following collaborative interventions.
- 1Apply supplemental oxygen via a high-flow delivery device.
- 2Administer intravenous propranolol.
- 3Administer oral propylthiouracil (PTU).
- 4Administer potassium iodide solution.
Answer
The correct sequence is to first apply supplemental oxygen, then administer intravenous propranolol, followed by propylthiouracil (PTU), and finally administer potassium iodide solution.
In a life-threatening acute deterioration, interventions must strictly follow the Airway-Breathing-Circulation (ABC) framework, integrated with disease-specific safety protocols. Oxygenation addresses the immense hypermetabolic demand (Airway/Breathing). Propranolol stabilizes the hyperdynamic cardiovascular system to prevent circulatory collapse (Circulation). Once ABCs are secured, the underlying endocrine crisis is treated. Propylthiouracil must be given first to halt new hormone synthesis. Potassium iodide is given last because if it is administered before the synthesis pathway is blocked, the iodine will act as a substrate to create more thyroid hormone, exacerbating the thyrotoxicosis.

Key Concept
Prioritizing ABCs (Airway, Breathing, Circulation) followed by the strict pharmacological sequencing required to safely manage thyrotoxic crisis (Thyroid Storm).
