Certified Emergency Nurse: CEN

Correct Answer: A

The nurse's first priority would be to notify the physician. The presence of bright red drainage on the dressing is an indication of hemorrhage. The other options are inappropriate for this patient.

Correct Answer: A

The nurse would want to monitor the patient's white blood cell count while they are taking this medication. This medication commonly causes agranulocytosis. Treatment would be interrupted if the white blood cell count drops below 3000 cells/mm. Agranulocytosis could become fatal if not detected.

Correct Answer: D

A chloride of 70 mEq/L would indicate a positive sweat test. In a sweat test, sweating is stimulated on the forearm with pilocarpine, and the amounts of sodium and chloride are measured. At least 50 mg of sweat is required to get an accurate test. A chloride level of 60 mEq/L or greater is considered a positive test.
