Correct Answer: C
Rationale: Rationale for Correct Answer C (require administration of insulin while taking prednisone):
1. Prednisone can increase blood glucose levels by reducing insulin sensitivity.
2. Metformin alone may not control blood glucose levels adequately in the presence of prednisone.
3. Therefore, the patient may require insulin to manage blood glucose levels while on prednisone.
Summary of Incorrect Choices:
A: This is incorrect because insulin administration is not necessary due to the rash or the interaction between metformin and prednisone.
B: This is incorrect because prednisone can actually increase blood glucose levels, leading to hyperglycemia rather than hypoglycemia.
D: This is incorrect because the rash is not likely caused by an interaction between metformin and prednisone, but rather an allergic reaction to an unknown cause.
