The nurse has reviewed the Provider Prescriptions at 0620. Which of the following provider prescriptions should the nurse implement first?

Rationale: A. Portable chest x-ray: A chest x-ray is important for identifying pulmonary congestion, cardiomegaly, or other structural abnormalities. However, imaging does not immediately correct hypoxemia or hemodynamic instability. In an acutely dyspneic client with low oxygen saturation and hypotension, stabilization of airway and breathing takes priority over diagnostic evaluation. B. 0.9% sodium chloride (0.9% NaCl) to run at 125 mL/hr: The client presents with hypotension, but also exhibits signs consistent with fluid overload, including orthopnea, lower-extremity edema, and pink-tinged sputum suggestive of pulmonary edema. Administering isotonic fluids could worsen intravascular volume excess and exacerbate respiratory compromise. C. Oxygen 2 L via nasal cannula: The client’s oxygen saturation is 91% on room air with tachypnea and signs of respiratory distress. Supplemental oxygen addresses impaired oxygenation and improves tissue perfusion, which is critical in the presence of hypotension and tachycardia. Following the ABC priority framework, correcting hypoxemia is the immediate intervention to prevent further deterioration. D. Furosemide 20 mg IV now: Furosemide is appropriate for suspected acute decompensated heart failure with fluid overload, as it promotes diuresis and reduces preload. However, its effects are not instantaneous, and the client is currently hypoxemic and hypotensive. Stabilizing oxygenation is the immediate priority before administering medications.
