A nurse is reinforcing teaching with a client who has type 1 diabetes mellitus. Which of the following statements from the client indicates to the nurse the teaching is effective?
“I will freeze unopened insulin vials.”.
“I should increase my insulin when I exercise.”.
“I should inject the insulin into my abdominal area.”.
“I will shake the insulin vial vigorously to mix.”.
The Correct Answer is C
Choice A rationale
Freezing unopened insulin vials is incorrect. Insulin should be stored in the refrigerator at a temperature between 36°F and 46°F (2°C and 8°C) until it is opened. Freezing insulin can cause it to lose its potency and effectiveness. Once opened, insulin vials can be kept at room temperature for up to 28 days, but they should never be frozen.
Choice B rationale
Increasing insulin when exercising is incorrect. Exercise generally lowers blood glucose levels, so clients with type 1 diabetes may need to decrease their insulin dose or consume additional carbohydrates to prevent hypoglycemia during and after physical activity. It is important for clients to monitor their blood glucose levels closely and adjust their insulin and carbohydrate intake accordingly.
Choice C rationale
Injecting insulin into the abdominal area is correct. The abdominal area is one of the recommended sites for insulin injection because it has a large surface area and provides consistent absorption. Other recommended sites include the upper outer arms, thighs, and buttocks. Rotating injection sites within the same area helps prevent lipodystrophy and ensures better insulin absorption.
Choice D rationale
Shaking the insulin vial vigorously to mix is incorrect. Insulin vials should be gently rolled between the hands to mix the contents. Shaking the vial vigorously can cause air bubbles to form, which can lead to inaccurate dosing. Proper mixing ensures that the insulin is evenly distributed and effective.

Correct Answer is D
Explanation
Choice A rationale
Positioning the lower extremities so that they are touching is incorrect because it can lead to adduction of the hip, which increases the risk of dislocation. After a total hip arthroplasty, it is important to maintain proper alignment of the hip joint to prevent dislocation. Keeping the legs apart with the use of an abduction pillow or wedge is recommended to maintain proper alignment and reduce the risk of complications.
Choice B rationale
Ensuring that the client’s heels are touching the bed is incorrect because it can lead to pressure ulcers. After a total hip arthroplasty, it is important to prevent pressure on the heels by using pillows or heel protectors to elevate the heels off the bed. This helps to reduce the risk of pressure ulcers and promotes better circulation to the lower extremities.
Choice C rationale
Instructing the client to avoid movement of the affected leg is incorrect because early mobilization is important for recovery. After a total hip arthroplasty, patients are encouraged to perform gentle exercises and mobilize as soon as possible to prevent complications such as deep vein thrombosis (DVT) and to promote healing. Immobilization can lead to stiffness, muscle atrophy, and other complications.
Choice D rationale
Preventing hip flexion of the affected extremity is correct because excessive hip flexion can increase the risk of dislocation. After a total hip arthroplasty, it is important to avoid positions that involve hip flexion greater than 90 degrees, such as sitting in low chairs or bending forward excessively. Maintaining proper hip precautions helps to reduce the risk of dislocation and promotes a safe recovery.
Correct Answer is B
Explanation
Choice A rationale
Type 2 diabetes is characterized by insulin resistance, not the overproduction of insulin. Over time, the pancreas may produce less insulin, but the primary issue is the body’s inability to use insulin effectively.
Choice B rationale
Type 2 diabetes involves the body’s inability to process glucose properly due to insulin resistance. This leads to elevated blood glucose levels and various complications if not managed effectively.
Choice C rationale
Hemoglobin binding to sugar is related to the measurement of HbA1c, which reflects average blood glucose levels over time. It is not a cause of type 2 diabetes.
Choice D rationale
The destruction of pancreatic cells is a characteristic of type 1 diabetes, an autoimmune condition. Type 2 diabetes is primarily due to insulin resistance and is not caused by an autoimmune response.
