A nurse has delegated to you to test urine for sugar and ketones in a client with a medical history of diabetes mellitus. You are aware that you will obtain the specimen:
  1. At bedtime.
  2. 30 minutes after meals and at bedtime.
  3. 30 minutes before meals and at bedtime.
  4. Before breakfast.
Explanation
Answer: C - In diabetes, some sugar appears in the urine (glucosuria or glycosuria). The diabetic person may also have acetone (ketone bodies, ketones) in the urine. To determine the presence of these substances in the urine, these tests are usually done four times a day -thirty minutes before meals and at bedtime. The doctor uses the test to make drug and diet decisions. Double-voided specimens are best for these tests.
