The 23-year-old patient is brought to the emergency department after contacting emergency services to report profound weakness that started in his feet and worsened and spread cranially over the past few days. He reports severe diarrhea after a camping trip a week ago. Upon assessment, strength, sensation, and deep tendon reflexes are significantly reduced, with the lower extremities more severely affected than his upper extremities. Vital signs are normal and the patient seems to be breathing well. The nurse anticipates which finding on the lumbar puncture result?  

Which arterial blood gas result is most indicative that the intubated and mechanically ventilated patient is ready to have the ventilator rate weaned?

The 49-year-old patient presented with a breast lump found during her monthly breast self-exam.
