An initial exposure is made using 800 mA, 0.02 sec, 16 mAs, 70 kVp, 58” SID, 4 “ OID, 5:1 grid ratio, 0.2 mm focal spot, 3.0 mm of filtration, and a 14 x 17 in field size. If the technologist changes the mAs to 5 for a second exposure without changing any other factors, what differences would you expect to see in the second exposure?1. increased IR exposure2. decreased IR exposure3. increased contrast4. decreased contrast5. increased spatial resolution6. decreased spatial resolution7. increased distortion8. decreased distortion

A 29-year-old man is evaluated in the emergency department following a high-speed motor vehicle collision. He sustained multiple fractures and suffered significant blood loss. Temperature is 38.7°C (101.7°F), heart rate is 110/min, blood pressure is 85/50 mmHg, respiratory rate is 24/min, and oxygen saturation is 90% on room air. He receives 2 units of O-negative packed red blood cells. Two hours after the transfusion, he develops dyspnea, hypoxemia, and a non-productive cough. On examination, he appears anxious, tachypneic, and is using accessory muscles of respiration. There are no rashes. The trachea is midline. There is no jugular vein distension. Pulmonary auscultation reveals bilateral rales. There is no lower extremity edema. The patient is intubated and mechanically ventilated. PaO2/FiO2 is equal to 230. Chest X-ray is shown below. Which of the following is the most likely diagnosis?
