The nurse is discussing insulin administration with an assigned patient. The patient reports that she prefers to use only certain sites for insulin injections. The patient questions why rotation of the sites is important. What response by the nurse is most appropriate?

"Unsightly fatty tumors can develop when you do not adequately rotate injection sites."

"Rotating your injection sites will help to reduce your risk of infection."

"Failing to rotate injection sites will improve your ability prevent an insulin reaction."

"Rotating your injection sites will help to reduce your risk for lipodystrophy."

Answer and Explanation

The Correct Answer is D

A. "Unsightly fatty tumors can develop when you do not adequately rotate injection sites.": While lipohypertrophy (fatty lumps under the skin) can develop from repeated use of the same injection site, the main reason for rotating sites is to avoid this and lipodystrophy.

B. "Rotating your injection sites will help to reduce your risk of infection.": Rotating injection sites can help prevent lipodystrophy, but it does not directly reduce the risk of infection. Proper technique is more important for preventing infection.

C. "Failing to rotate injection sites will improve your ability to prevent an insulin reaction.": Failing to rotate injection sites does not prevent insulin reactions. In fact, using the same site too often can cause insulin absorption problems and potentially affect blood glucose control.

D. "Rotating your injection sites will help to reduce your risk for lipodystrophy.": Lipodystrophy (which includes lipohypertrophy and lipoatrophy) can occur when insulin is repeatedly injected into the same site. Rotating injection sites helps to reduce the risk of these issues and ensures consistent insulin absorption.

Correct Answer is D

Explanation

A. Atherosclerotic vascular changes: While atherosclerosis is common in diabetics, it primarily affects circulation and the cardiovascular system. Although impaired circulation can contribute to slower healing, it is not the primary cause of increased infection risk.

B. Deficient protein reserves: Although protein malnutrition can impair the immune response, diabetes does not necessarily lead to deficient protein reserves. The increased risk of infection is more closely related to high glucose levels rather than malnutrition.

C. Inadequacy of blood cell production: Inadequate blood cell production (such as anemia) is not a common result of diabetes. While diabetes can cause complications that affect circulatory health, the increased infection risk is primarily due to elevated glucose levels.

D. High glucose levels: High blood glucose levels can impair the function of white blood cells, which are essential for the body's ability to fight infection. Hyperglycemia also provides an ideal environment for the growth of bacteria and fungi, making diabetics more prone to infections, especially in areas like the skin and urinary tract.

A. Decreased free thyroxine index B. Decreased thyroid stimulating hormone C. Decreased triiodothyronine D. Decreased thyrotropin receptor antibodies

Correct Answer is B

Explanation

A. Decreased free thyroxine index: In Graves' disease, there is an overproduction of thyroid hormones, including thyroxine (T4), leading to an increase in the free thyroxine index, not a decrease. Elevated T4 levels are typical in hyperthyroidism associated with Graves' disease.

B. Decreased thyroid stimulating hormone (TSH): In Graves' disease, the body produces excess thyroid hormones, which suppresses the pituitary gland’s production of TSH. As a result, TSH levels are typically low in Graves' disease.

C. Decreased triiodothyronine (T3): Graves' disease usually results in increased levels of T3 and T4 due to the overactive thyroid. A decrease in T3 would be inconsistent with the hyperthyroid state seen in this disorder.

D. Decreased thyrotropin receptor antibodies: In Graves' disease, there is an increase in thyrotropin receptor antibodies, which stimulate the thyroid to produce excess thyroid hormones. These antibodies are often elevated, not decreased.
