A nurse is caring for a client who is prescribed a medication for an off-label use. Which statement best describes off-label use?

• Injects insulin into abdomen at 45-90 degree angle: Proper injection angle ensures the insulin is delivered into subcutaneous tissue, promoting optimal absorption. The abdomen is the preferred site for rapid-acting insulin like lispro. The client demonstrates correct technique, showing effective learning.

• Checks blood glucose immediately prior to injection: Monitoring blood glucose before insulin administration is essential for safe dosing and avoiding hypoglycemia. The client correctly performs this step, indicating understanding of blood glucose monitoring and insulin timing.

• Utilizes correct insulin syringe for injection: Using the correct syringe type ensures accurate measurement of insulin units. The client demonstrates proper selection and use, reflecting adherence to safe injection practices.

• Selects site different from previous injection site: Rotating injection sites prevents lipodystrophy and maintains consistent insulin absorption. The client demonstrates correct site rotation, showing understanding of long-term injection site care.

• Massages the site after removing the needle: Massaging the injection site can alter insulin absorption and may lead to bruising or tissue damage. Clients should be taught to avoid massaging immediately after injection. This indicates the client needs additional instruction.

• Shakes insulin to mix it uniformly: Rapidly shaking insulin can create air bubbles and denature the protein, reducing effectiveness. Insulin should be gently rolled or inverted if mixing is needed. This behavior requires further teaching.

A. Hypoglycemia is a common side effect: Repaglinide is a meglitinide that stimulates rapid, short-acting insulin release from pancreatic beta cells, increasing the risk of hypoglycemia, especially if meals are skipped or delayed. Client education should emphasize recognizing early signs, carrying a source of glucose, and timing doses with meals to prevent severe hypoglycemia.

B. Bruising may occur when taking this medication: Bruising is not a typical side effect of repaglinide. Unlike anticoagulants or antiplatelet agents, repaglinide does not affect platelet function or clotting pathways, so clients do not need to monitor for unusual bruising as part of routine education.

C. Take this medication at night before bed: Repaglinide should be taken with meals, usually 0–30 minutes before eating, to match insulin secretion with postprandial glucose. Taking it at night without food increases the risk of hypoglycemia, particularly during prolonged fasting or sleep.

D. Stop taking if you experience hyperglycemia: Experiencing high blood glucose does not warrant abrupt discontinuation of repaglinide. Instead, the client should notify the healthcare provider for dose adjustment or evaluation of adherence, diet, or additional therapy while continuing the medication safely.
