12. D is the correct answer. An empyema (pleural space abscess) is not likely to cause hemopytsis. Wegner's Granulamatosis is a vasculitis that can cause pulmonary hemorrhage and needs immunosuppression. Active TB can cause hemoptysis but is usually accompanied with night sweats. Pulmonary embolus can cause hemoptysis also.

11. The correct answer is C. This is a clinical scenario consistent with DKA. This would be more difficult to interpret if this COPD patient was a chronic COPD retainer. You would have to look for a widened anion gap as well as a serum acetone to make the diagnosis. Given the circumstances it is really not necessary.
