The nurse is caring for a client with diabetes mellitus, type 1 who asked for the meaning of glycemic index. Which of the following responses by the nurse would be correct?

"It describes a list of foods that are alike in terms of the amount of carbohydrate, fat, protein, and calories in each food."

"It is a value assigned to foods based on how slowly or how quickly those foods cause increases in your blood glucose level."

"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."

"It is a scoring system that describes the amount of carbohydrates, in grams, that is present in each serving of a food."

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is D

Explanation

A. A needle biopsy of the thyroid is typically done under local anesthesia, not general anesthesia. The client would be awake during the procedure, although they may be given a sedative to help them relax.
B. A needle biopsy is used to obtain a sample of tissue for testing, not to remove the cancer. The procedure helps diagnose the presence of cancer, but further treatment like surgery would be necessary to remove any cancer.
C. While a needle biopsy can confirm the presence of cancer, it does not provide information about the stage of cancer. Additional imaging and tests would be required to determine the stage.
D. Although the procedure typically involves inserting a needle through the skin (often without making a large incision), the biopsy involves removing a small sample of tissue for examination. This is the correct understanding of a needle biopsy.

A. "Donepezil will stop the progression of the disease." B. "You can expect an immediate improvement in your ability to think." C. "Donepezil helps to manage the symptoms of Alzheimer's disease." D. "This medication slows the uptake of acetylcholine."

Correct Answer is C

Explanation

A. Donepezil (Aricept) does not stop or cure Alzheimer's disease. It helps to manage symptoms, but it does not halt the progression of the disease. The disease will still progress, but the medication may help improve cognitive function and slow down symptom deterioration temporarily.
B. Donepezil may take several weeks to months to show any noticeable effects. Immediate improvements in cognitive function are unlikely, and it should not be expected to cause quick or dramatic changes in thinking.
C. Donepezil is a cholinesterase inhibitor that works by increasing acetylcholine levels in the brain, which helps to improve communication between nerve cells. It helps manage the cognitive symptoms of Alzheimer's disease, such as memory loss and confusion, but does not cure or prevent the disease.
D. Donepezil works by inhibiting acetylcholinesterase, the enzyme that breaks down acetylcholine. By doing this, it helps increase the availability of acetylcholine in the brain, rather than slowing its uptake. This increased availability can help improve cognitive function in people with Alzheimer's disease.
