The home health care nurse is visiting a client who was recently diagnosed with type 2 diabetes mellitus. The client is prescribed repaglinide (Prandin) and metformin (Glucophage) and asks the nurse to explain these medications. The nurse should reinforce which instructions to the client?(Select one that does not apply.).

- B. The repaglinide is not taken if a meal is skipped.
- C. The repaglinide is taken 30 minutes before eating.
- D. Candy or another simple sugar is carried and used to treat mild hyperglycemia episodes.
Correct Answer: D
Rationale: Repaglinide is a rapid-acting oral hypoglycemic agent that stimulates pancreatic insulin secretion that should be taken before meals, and that should be withheld if the client does not eat. Hypoglycemia is a side effect of repaglinide and the client should always be prepared by carrying a simple sugar with her or him at all times. Metformin is an oral hypoglycemic given in combination with repaglinide and works by decreasing hepatic glucose production. A common side effect of metformin is diarrhea. Correct answers include: 1, 2, 3, 4.
