Final answer:
If the CPCT intending to draw a GTT finds that the patient may have eaten breakfast, they must verify the fasting requirements of the test. An empty breakfast plate signifies that the test results may be compromised, and a reschedule might be necessary. Further tests such as ITT and GuTT could be required for a positive GTT result.
Step-by-step explanation:
When a CPCT needs to draw a GTT (Glucose Tolerance Test), it's important to ensure that patient preparation is appropriate for the test. If the CPCT observes an empty breakfast plate at the patient's bedside, they should verify if the patient was required to fast before the test. Typically for a glucose tolerance test, fasting is necessary to get accurate results. It is important to confirm the duration of the fast and that no food intake was supposed to happen prior to the test. If the test requires fasting and the patient has eaten, this could invalidate the test results, and the CPCT may need to reschedule the test.
Upon a positive GTT indicating diabetes mellitus, the CPCT would need to discuss with the healthcare team about the next steps, which could include an Insulin Tolerance Test (ITT) and Glucagon Tolerance Test (GuTT) to determine the type of diabetes and appropriate treatment.
