A patient with type 1 DM expresses concern about developing retinopathy due to a chronic disease. How should the nurse reply?

Correct Answer: C

Rationale: Good control of blood glucose levels and blood pressure is essential in reducing the risk of diabetic retinopathy and its progression. Research has shown that maintaining tight glycemic control and managing hypertension can significantly decrease the likelihood and severity of retinopathy in patients with diabetes.

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.

Correct Answer: A

Rationale: To ensure effective oral care, the nurse should temporarily remove the nasal cannula while performing oral care procedures. This allows better access to the client's mouth and prevents interference with oral hygiene.
