A nurse is reinforcing teaching with a client who is scheduled for a blood test to measure her thyroid stimulating hormone (TSH) level. Which of the following statements should the nurse give?

Choice A reason: A fruity odor in the breath is a symptom of hyperglycemia, especially when it is severe and causes ketoacidosis. Ketoacidosis is a condition where the body produces ketones, which are acidic substances that result from the breakdown of fat for energy when there is not enough insulin or glucose available. Ketones can make the breath smell fruity or like nail polish remover.

Choice B reason: A decreased appetite is not a symptom of hyperglycemia. On the contrary, an increased appetite or hunger is a symptom of hyperglycemia, as the body tries to compensate for the lack of glucose in the cells by stimulating the hunger center in the brain.

Choice C reason: An increased thirst is a symptom of hyperglycemia, as the body tries to flush out the excess glucose and ketones in the blood through urine. This leads to dehydration and thirst signals in the brain.

Choice D reason: A blurry vision at times is a symptom of hyperglycemia, as high blood glucose levels can cause swelling and damage to the lens of the eye, affecting its ability to focus light properly. This can lead to temporary or permanent vision problems.

Choice A reason: Wearing closed-toed shoes daily is a good practice for people with diabetes, as it can protect the feet from injuries and infections. However, it is not the most important action for preventing long-term complications of retinopathy and neuropathy. These complications are mainly caused by high blood glucose levels that damage the blood vessels and nerves in the eyes and feet.

Choice B reason: Maintaining stable blood glucose levels is the most important action for preventing long-term complications of retinopathy and neuropathy. High blood glucose levels can cause oxidative stress, inflammation, and endothelial dysfunction, which impair the blood flow and oxygen delivery to the eyes and feet. This can lead to nerve damage (neuropathy) and vision loss (retinopathy) over time. Keeping blood glucose levels within the target range can reduce the risk of these complications and slow down their progression if they already exist.

Choice C reason: Planning to have an eye examination once per year is a recommended action for people with diabetes, as it can help detect and treat retinopathy before it causes irreversible damage to the retina. However, it is not the most important action for preventing long-term complications of retinopathy and neuropathy. Eye examinations cannot prevent retinopathy from occurring or worsening; they can only monitor its status and provide appropriate interventions.

Choice D reason: Examining your feet carefully every day is another recommended action for people with diabetes, as it can help identify and treat any signs of neuropathy, such as numbness, tingling, pain, or ulcers. However, it is not the most important action for preventing long-term complications of retinopathy and neuropathy. Foot examinations cannot prevent neuropathy from occurring or worsening; they can only monitor its status and provide appropriate care.
