The answer to question 4  D
The hemoglobin A1c (A1C) test (formerly called the glycosylated hemoglobin test) measures blood glucose over a period of many weeks. Glucose in the bloodstream attaches itself to the hemoglobin A (red blood cell) molecule and remains there for the life span of the red blood cell. Physicians use A1C test results to prescribe adjustments to a patient's treatment program for managing diabetes. Results of 4.9 to 6.7 are considered excellent results. Good results are between 7.6 and 8.5. Fair results are between 9.4 and 10.0. Poor control is considered between 12.1 and 13.0.

The answer to question 5  D
Since the urine will have flushed out the organisms, the nurse should wait at least 1 hour postvo-id before collecting the specimen. The infection has not been confirmed, so no report should be made at this time. The patient's temperature should be obtained each shift. Administering anti-biotics before cultures are drawn may cause cultures to be negative even though the drug or the dose may not be sufficient to cure the infection. If possible, obtain cultures prior to administering antibiotics.

The answer to question 6  B
The 17-KS test is used to determine the amount of androgen metabolites in the urine and requires a 24-hour urine collection. The urine collection container must be kept chilled, so the nurse should ensure that adequate space is available in the specimen refrigerator. This test does not require the patient to fast. The nurse should consult with the physician and laboratory regarding the patient's medications but should not withhold any without orders. Antacids will not alter the test results.
