When is the best time to obtain a urinary specimen for testing sugar and ketones in a client with diabetes Mellitus?

Immediately after meals
30 minutes after meals and at bedtime
Before breakfast
Only when the client feels discomfort

The correct answer is: 30 minutes after meals and at bedtime

Obtaining a urinary specimen for testing sugar and ketones in a client with diabetes Mellitus is most effective when done 30 minutes after meals and at bedtime. This timing is significant because it allows for the detection of postprandial (after eating) changes in blood glucose levels, which can lead to the presence of sugar and ketones in the urine. After meals, especially in individuals with diabetes, the blood sugar levels can rise significantly as a result of carbohydrate intake. Collecting a urine sample approximately 30 minutes post-meal can help in assessing how the body is managing the glucose effectively and whether ketones are present as a byproduct of insufficient insulin delivery or metabolic activity. Bedtime specimens are also important since they can reflect the overnight metabolic state and provide insight into how well the client's blood sugar has been controlled throughout the day. This combination of timing allows for a comprehensive assessment of the individual's renal excretion of glucose and ketones, which is crucial for managing diabetes effectively.
