Final answer:
Mindy can safely continue taking oral contraceptives during the oral glucose tolerance test (OGTT).
Step-by-step explanation:
For an oral glucose tolerance test (OGTT), Mindy is instructed to discontinue many of her medications for 3 days before the test. Among the options provided, it is safe for Mindy to continue taking oral contraceptives during this period. These medications do not interfere with the accuracy of the test or impact the glucose levels being measured. However, it's always best to consult with a healthcare professional to ensure the safe continuation of any medication during medical tests or procedures.
