The nurse is teaching a patient recently diagnosed with type 1 diabetes mellitus (DM) about the disease. What information should the nurse include?

A. Type 1 diabetes is an autoimmune condition where the body's immune system attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the pancreas produces little to no insulin, which is essential for regulating blood glucose levels.
B. Type 1 diabetes is not reversible. It is a lifelong condition that requires ongoing management with insulin therapy. While diet, exercise, and weight management are important for overall health and can help manage blood glucose levels, they cannot reverse type 1 diabetes.
C. This description is characteristic of type 2 diabetes, not type 1. In type 2 diabetes, the body’s cells become resistant to the effects of insulin, and the pancreas may not produce enough insulin. In type 1 diabetes, the problem is the lack of insulin production due to autoimmune destruction of the pancreatic beta cells.
D. Insulin is not released into the gastrointestinal tract. Insulin is a hormone that is released into the bloodstream by the pancreas. Its primary role is to help regulate blood glucose levels by facilitating the uptake of glucose into the body's cells for energy.

B. Expiratory wheezes are high-pitched, musical sounds produced by air passing through narrowed or obstructed airways. Wheezing is a hallmark sign of asthma, particularly during an exacerbation, and is usually more pronounced during expiration due to the increased effort required to expel air through the narrowed airways.
A. A pleural friction rub is a grating sound produced by the movement of inflamed pleural surfaces rubbing together. It is typically heard in conditions such as pleuritis (inflammation of the pleura) or pleurisy. This sound is not commonly associated with asthma exacerbations.
C. Rhonchi are low-pitched, snoring-like sounds that occur due to the presence of mucus or other secretions in the larger airways. While rhonchi can be heard in conditions with increased mucus production, such as bronchitis, they are not typically the primary sound associated with asthma exacerbations.
D. Fine rales, also known as crackles, are high-pitched, popping sounds heard during inspiration. They are usually associated with conditions involving fluid in the alveoli, such as pulmonary edema or interstitial lung disease. Crackles are not characteristic of asthma.
