The nurse is evaluating teaching provided to a patient with type 1 diabetes mellitus. Which patient observation indicates that medication teaching has been effective?
Inserts the needle at a 25-degree angle prior to injecting the medication
Provides an injection in the thigh after an abdominal injection in the morning
Uses a 1 mL syringe to measure insulin dose
Places a new injection an inch away from previous injection site
The Correct Answer is B
A. Incorrect → Insulin injections should be administered at a 90-degree angle unless the patient has minimal subcutaneous fat, in which case a 45-degree angle is used. A 25-degree angle is too shallow and may lead to improper absorption.
B. Rotating insulin injection sites helps prevent lipodystrophy and ensures consistent absorption. The patient’s decision to inject in the thigh after using the abdomen in the morning demonstrates proper site rotation.
C. Incorrect → Insulin should be administered with a U-100 insulin syringe (not a 1 mL syringe) to ensure accurate dosing.
D. Incorrect → While injecting an inch away from a previous site is reasonable, the preferred practice is rotating between different anatomical sites to prevent tissue damage and inconsistent absorption.
