The nurse has completed post-operative teaching for a client with a new vagal nerve stimulator (VNS). Which of the following statements by the client would indicate the need for more teaching?

My doctor can change the settings as needed.

I am so glad that I will never have another seizure.

This devise will send electrical signals to my brain.

I know a potential complication is a cough or throat spasm.

Answer and Explanation

The Correct Answer is B

A. It is correct that the doctor can change the settings of the VNS as needed using a special programming device. This is a true and expected understanding.
B. Saying "I will never have another seizure" indicates a misunderstanding. While the vagal nerve stimulator can reduce the frequency and severity of seizures, it is not a cure and does not guarantee complete seizure prevention. This statement reflects unrealistic expectations and suggests the need for further teaching.
C. The VNS sends electrical signals to the brain via the vagus nerve to help prevent seizure activity—this is an accurate understanding of its function.
D. Cough or throat spasm is a known side effect or complication of VNS, so this statement reflects appropriate understanding.

Correct Answer is A

Explanation

A. Rubbing the injection site after insulin administration is not recommended, as it can increase the risk of bruising or irritation. Insulin should be injected into the subcutaneous tissue, and massaging or rubbing the site can cause the insulin to be absorbed too quickly, leading to unpredictable blood sugar levels.
B. Injecting the needle at a 90-degree angle is the correct technique for subcutaneous insulin injection, especially when using shorter needles. A 90-degree angle ensures the insulin is delivered into the subcutaneous tissue.
C. Grasping the skin helps to ensure that the insulin is injected into the subcutaneous layer and not into the muscle, which can affect absorption.
D. Rotating injection sites is important to prevent tissue damage or lipodystrophy (thickening or atrophy of the skin). Following a pattern helps ensure that insulin is injected into different areas for consistent absorption.

A. "It describes a list of foods that are alike in terms of the amount of carbohydrate, fat, protein, and calories in each food." B. "It is a value assigned to foods based on how slowly or how quickly those foods cause increases in your blood glucose level." C. "It is a diet plan that tracks the amount of carbohydrates in food to ensure that a predetermined amount is consumed during a given meal." D. "It is a scoring system that describes the amount of carbohydrates, in grams, that is present in each serving of a food."

Correct Answer is B

Explanation

A. "It describes a list of foods that are alike in terms of the amount of carbohydrate, fat, protein, and calories in each food." This definition does not describe the glycemic index. The glycemic index focuses on how quickly a food raises blood glucose, not on the carbohydrate, fat, protein, and calorie content of foods.
B. "It is a value assigned to foods based on how slowly or how quickly those foods cause increases in your blood glucose level." The glycemic index (GI) measures how quickly a carbohydrate-containing food raises blood glucose levels after consumption. Foods with a high GI cause rapid spikes in blood glucose, while those with a low GI cause slower increases.
C. "It is a diet plan that tracks the amount of carbohydrates in food to ensure that a predetermined amount is consumed during a given meal." This describes carbohydrate counting or a carbohydrate-based meal plan, not the glycemic index.
D. "It is a scoring system that describes the amount of carbohydrates, in grams, that is present in each serving of a food." This describes the concept of carbohydrate counting, which focuses on the total grams of carbohydrates in food, not the rate at which those carbohydrates affect blood glucose.
