A patient with type 1 DM expresses concern about developing retinopathy due to a chronic disease. How should the nurse reply?
Newer laser surgery can improve sight after retinal hemorrhage.
The high incidence of cataracts can be surgically corrected.
Good control of blood glucose and blood pressure can reduce the risk.
Diabetes is low as a cause for blindness in the United States.
The Correct Answer is C
C. 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.
A. Laser surgery is a treatment option for certain complications of diabetic retinopathy, such as retinal hemorrhage or retinal detachment. However, it's essential to emphasize that prevention through good glycemic control and regular eye exams is key to reducing the risk of these complications, rather than relying solely on surgical interventions after they occur.
B. Cataracts are more common in individuals with diabetes and can be surgically corrected but this statement does not directly address the concern about retinopathy. Cataracts and retinopathy are separate ocular complications of diabetes, each requiring different management strategies.
D. Diabetes remains one of the leading causes of blindness in the United States, primarily due to its association with diabetic retinopathy. While advancements in diabetes management and eye care have helped reduce the incidence of blindness, it is still a significant concern for individuals with diabetes.

Correct Answer is A
Explanation
A. This range is generally considered acceptable for most patients with COPD. It provides a balance between ensuring adequate oxygenation while avoiding the risk of oxygen toxicity. Oxygen saturation levels within this range can help alleviate symptoms of hypoxemia without causing hyperoxia.
B. Oxygen saturation levels below 90% can lead to significant hypoxemia and exacerbate respiratory distress in individuals with COPD. Maintaining oxygen saturation levels above 90% is typically recommended to prevent complications associated with hypoxemia.
C. This range is appropriate for some patients but it may not be ideal for all patients with COPD. Oxygen saturation levels at the higher end of this range (e.g., 100%) can increase the risk of oxygen toxicity in patients with COPD who retain carbon dioxide (CO2) due to their chronic respiratory condition.
D. Oxygen saturation levels within this range help to balance the need for oxygen supplementation with the risk of hyperoxia and oxygen toxicity. However, individual patient factors, such as the severity of COPD, baseline oxygen saturation levels, and comorbidities, should be considered when determining the target range for oxygen saturation.
Correct Answer is C
Explanation
C. Elevating the head of the bed can help reduce nighttime GERD symptoms. By elevating the head of the bed by about 6 to 8 inches (15 to 20 centimeters), gravity helps prevent stomach acid from refluxing into the esophagus while the individual is lying down. This position can alleviate symptoms such as heartburn, regurgitation, and coughing during sleep.
A. Alcohol consumption, especially before bedtime, can exacerbate GERD symptoms. Alcohol relaxes the lower esophageal sphincter (LES), allowing stomach acid to reflux into the esophagus more easily.
B. Sleeping on the stomach with the head flat can worsen GERD symptoms. This position can increase pressure on the stomach and promote reflux of stomach acid into the esophagus. Sleeping on the stomach is generally not recommended for individuals with GERD.
D. Eating a large meal or having a snack shortly before bedtime can increase the likelihood of GERD symptoms during sleep. It's generally recommended to avoid eating large meals or heavy snacks close to bedtime. Instead, individuals with GERD should aim to finish eating at least 2 to 3 hours before lying down to sleep.
