The nurse is caring for a client experiencing tachypnea, dyspnea, and confusion. Which of the following orders does the nurse anticipate receiving from the healthcare provider? Select all that apply

A. A chest x-ray helps identify pulmonary causes of dyspnea, such as pneumonia, pulmonary edema, pneumothorax, or pleural effusion, which could explain the client’s tachypnea and hypoxia. B. CBC can detect infection (elevated WBCs), anemia (low hemoglobin), or other hematologic abnormalities that may contribute to confusion, hypoxia, or respiratory compromise. C. MRI is rarely used as an initial diagnostic tool for acute respiratory distress or confusion because it is time-consuming and not ideal for unstable patients. It is generally reserved for detailed evaluation of mediastinal masses or vascular abnormalities. D. ABGs provide immediate information about oxygenation, ventilation, and acid-base status, which is critical in a client with tachypnea, dyspnea, and confusion to guide oxygen therapy and interventions. E. Elevated lactate levels indicate tissue hypoperfusion and anaerobic metabolism, which may be present in sepsis or shock. This test helps assess the severity of the client’s condition and monitor response to interventions.
