Write answer in between .Q:A 75-year-old man with a 35-pack-year history of smoking is found to be lethargic three days being admitted with a femur fracture following a motor vehicle accident. His recovery has been progressing well thus far, though pain continued to be present. On exam, the patient minimally responsive with pinpoint pupils. Vital signs are blood pressure of 11565 mmHg, HR 80min, respiratory rate 6min, and oxygen saturation of 87 on room air. Arterial blood gas ABG shows a pH of 7.24 Normal: 7.35-7.45, PaCO2 of 60mm Hg normal 35-45mm Hg, a HCO3 of 23 mEqL normal 21-28 mEqL and a Pa02 of 60 mmHg normal 80-100 mmHg. Which of the following is the most appropriate therapy at this time?? A: Repeat catheterization, B: Glucocorticoids, C: Heparin, D: Naloxone, E: Emergent cardiac surgery,  <response>: This is a question about a patient with respiratory acidosis likely due to hypoventilationrespiratory depression. The key findings are an elderly patient with a history of smoking who is minimally responsive with pinpoint pupils and has an arterial blood gas showing respiratory acidosis low pH, high PaCO2. The most likely cause is opioid-induced respiratory depression given the pinpoint pupils and hypoventilation. Naloxone is an opioid antagonist that can reverse opioid overdose and respiratory depression. Therefore, naloxone would be the most appropriate therapy.Choices A, B, C, and E are not relevant to treating opioid-induced respiratory depression.D: Naloxone
