The nurse cares for a 78-year-old client admitted to the medical intensive care unit in respiratory distress. The Nurse receives orders. Click to highlight the 3 orders the nurse would implement first.

A. Insert urinary catheter: While urinary catheterization allows monitoring of urine output and renal perfusion, it does not directly address the client’s immediate life-threatening respiratory failure. This is a secondary intervention once airway and breathing are stabilized. B. Suction endotracheal tube as needed: The client has crackles, diminished breath sounds, and likely increased secretions from pneumonia. Suctioning removes airway obstruction, decreases airway resistance, and improves ventilation and oxygenation. Retained secretions can worsen V/Q mismatch and hypoxemia, making this an immediate priority. C. Mark endotracheal tube where it touches the teeth: Marking the tube helps monitor for displacement, but it is a safety/monitoring measure rather than an immediate life-saving intervention. It does not correct hypoxemia or ventilatory failure. D. Amoxicillin 500 mg IVPB every 12 hours: Antibiotic therapy is essential for treating the underlying infection (likely bacterial pneumonia), but it does not provide immediate correction of oxygenation or ventilation. Its effects are delayed compared to airway interventions. E. Midazolam 2 mg IVP every 1 hour as needed for agitation: Agitation increases oxygen consumption, respiratory workload, and can cause ventilator dyssynchrony. Sedation improves ventilator compliance, reduces oxygen demand, and facilitates effective mechanical ventilation, directly stabilizing gas exchange. F. Acetaminophen 650 mg per rectum every 8 hours as needed for temperature 100.8: The client’s temperature is only mildly elevated (99.8°F), and fever management is not a priority compared to severe hypoxemia and respiratory acidosis. G. Perform 12 lead EKG: Cardiac monitoring may be useful given tachycardia, but it does not address the primary issue of respiratory failure and impaired gas exchange. H. Call for chest x-ray: A chest x-ray is essential to confirm tube placement, assess for pneumonia, consolidation, or complications like ARDS. This directly guides respiratory management and ensures proper ventilation, making it a priority diagnostic intervention. I. Arterial blood gas in 30 minutes: Repeat ABG helps evaluate response to therapy, but immediate interventions to correct hypoxemia and ventilation must occur first before reassessment.
