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

Correct Answer: A

Rationale: 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.

Correct Answer: D

Rationale: Oxygen therapy is indicated in clients with COPD to prevent complications of hypoxia, such as tissue damage and respiratory failure.

Correct Answer: C

Rationale: A non-rebreather mask is most appropriate for a client with pneumonia requiring high oxygen concentrations due to severe hypoxemia. It delivers up to 95% oxygen, ensuring adequate oxygenation while the underlying infection is treated. (Note: This question lacks a direct answer in the document; rationale is generated based on context from Question 1 and general medical knowledge.)

Correct Answer: B

Rationale: Oxygen toxicity can occur with prolonged exposure to high levels of oxygen. The nurse should closely monitor the client for signs of oxygen toxicity, such as substernal pain, respiratory distress, and changes in mental status.

Correct Answer: A

Rationale: The nurse should ensure that the reservoir bag attached to the non-rebreather mask remains inflated at all times. The inflated bag provides a reservoir of oxygen and ensures a high concentration of oxygen is delivered to the client during inhalation.
