A nurse is caring for a client 2 hr following abdominal surgery. The intraoperative medication record indicates the client received midazolam, propofol, rocuronium, and ondansetron. The client is increasingly difficult to arouse and has shallow respirations at 8/min. ABG results are pH 7.28, PaCO₂ 58 mm Hg, HCO₃⁻ 24 mEq/L, and PaO₂ 80 mm Hg. Which medication should the nurse anticipate administering?
