Final answer:
The highest priority for the given Type 1 DM patient is oxygen therapy, due to the low oxygen saturation levels indicating respiratory distress. Insulin, antipyretics, and antibiotics should follow, prioritizing based on the clinical acuity.
Step-by-step explanation:
The 22-year-old patient with Type 1 Diabetes Mellitus (DM) presenting with a cough, fever, fatigue, and recent upper respiratory infection requires immediate medical attention. Given the vital signs reported, oxygen therapy is the highest priority prescription. The patient's oxygen saturation (O2Sat) at 92% on 2 L nasal cannula (NC) is below the normal range, which is typically 95-100%. Low oxygen saturation accompanied by tachycardia, tachypnea, and fever suggests that the patient may be experiencing significant respiratory distress, possibly due to pneumonia or another serious infection. Adequate oxygenation is crucial to ensure tissue perfusion and prevent hypoxia.
While insulin management is also critical in a patient with Type 1 DM, especially during illness when blood sugars can fluctuate more, immediate correction of hypoxemia takes precedence. Once stable oxygen levels are achieved, blood glucose should be closely monitored, and insulin should be administered as needed to maintain glycemic control. Administration of antipyretics can also be considered to manage the fever, and antibiotics may be necessary if a bacterial infection is confirmed or highly suspected.
It is important to address all aspects of the patient's care, including potential infections, glycemic control, and fever management, while prioritizing interventions based on the acuity of the clinical presentation.
