The nurse is teaching a patient recently diagnosed with type 1 diabetes mellitus (DM) about the disease. What information should the nurse include?
Type 1 DM is caused by the inability of the pancreas to produce insulin.
Type 1 DM is reversible with diet, weight loss, and exercise programs.
Type 1 DM is when glucose remains in the bloodstream because tissues are resistant to insulin.
Insulin is released into the gastrointestinal tract to aid in the digestion process.
The Correct Answer is A
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.

Correct Answer is B
Explanation
B. The alveoli are tiny air sacs within the lungs where gas exchange occurs. Oxygen from inhaled air diffuses across the thin walls of the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
A. The bronchi are the main airways that branch off from the trachea and lead to the lungs. While the bronchi play a crucial role in conducting air to and from the lungs, gas exchange does not occur in the bronchi themselves.
C. The nasal passages, also known as the nostrils or nares, are the passages through which air enters the respiratory system. While the nasal passages warm, humidify, and filter the air as it enters the body, gas exchange does not occur in this area.
D. The larynx, or voice box, is located at the top of the trachea and is involved in breathing, swallowing, and vocalization. However, gas exchange does not occur in the larynx.
Correct Answer is C
Explanation
C. The spacer helps to deliver more medication to the lungs by holding the medication in the chamber, allowing the patient to inhale it more slowly and deeply. This results in better deposition of the medication in the lower airways and reduces the amount of medication that is deposited in the mouth and throat.
A. The primary purpose of the spacer is to increase the amount of medication that reaches the lungs and to reduce the amount deposited in the oropharynx (throat). The spacer helps to ensure that more medication is delivered directly to the airways where it is needed, thereby enhancing the effectiveness of the treatment and reducing side effects.
B. The exhalation slots or vents on a spacer are designed to allow the patient to exhale easily without removing the device from the mouth. The lips should form a tight seal around the mouthpiece of the spacer to ensure effective inhalation, but the exhalation slots should not be intentionally covered.
D. When using a spacer with an MDI, the patient should inhale slowly and deeply. Rapid inhalation can cause the medication to be deposited in the upper airways rather than reaching the lungs. A slow and deep inhalation allows for better medication delivery to the lower airways.
