For the patient with diabetes mellitus, which microvascular complication of the blood vessel structure may occur? Select all that apply. One, some, or all responses may be correct.
Nephropathy
Neuropathy
Peripheral vascular disease
Cerebral vascular disease
Retinopathy
Correct Answer : A,B,E
Choice A: Nephropathy
Diabetic nephropathy is a common microvascular complication of diabetes mellitus. It is characterized by damage to the small blood vessels in the kidneys, leading to progressive kidney disease. The condition is often identified by the presence of protein in the urine (proteinuria) and can progress to end-stage renal disease if not managed properly. The primary mechanism involves hyperglycemia-induced damage to the glomeruli, the filtering units of the kidneys. This damage results in increased permeability and eventual scarring, impairing kidney function. Effective management of blood glucose levels and blood pressure is crucial in preventing or slowing the progression of diabetic nephropathy.
Choice B: Neuropathy
Diabetic neuropathy refers to nerve damage caused by chronic high blood sugar levels. It is another significant microvascular complication of diabetes. This condition can affect various types of nerves, including sensory, motor, and autonomic nerves. Symptoms may include pain, tingling, numbness, and loss of sensation, particularly in the extremities. Diabetic neuropathy can lead to severe complications such as foot ulcers and infections, which may necessitate amputation. The pathophysiology involves hyperglycemia-induced oxidative stress and inflammation, leading to nerve damage. Tight glycemic control and regular monitoring are essential in managing diabetic neuropathy.
Choice E: Retinopathy
Diabetic retinopathy is a leading cause of blindness among adults with diabetes. This microvascular complication involves damage to the small blood vessels in the retina, the light-sensitive tissue at the back of the eye. There are two main types: non-proliferative and proliferative retinopathy. Non-proliferative retinopathy is characterized by microaneurysms, hemorrhages, and exudates, while proliferative retinopathy involves the growth of new, fragile blood vessels that can bleed and cause retinal detachment. The primary cause is prolonged hyperglycemia, which damages the retinal blood vessels. Regular eye examinations and good glycemic control are vital in preventing and managing diabetic retinopathy.
Choice C: Peripheral Vascular Disease
Peripheral vascular disease (PVD) is not classified as a microvascular complication but rather a macrovascular one. It involves the narrowing or blockage of the blood vessels outside the heart and brain, primarily affecting the arteries in the legs. PVD is associated with atherosclerosis, where plaque builds up in the arterial walls, leading to reduced blood flow. Symptoms include leg pain, cramping, and ulcers. While PVD is a significant concern for individuals with diabetes, it is not considered a microvascular complication.
Choice D: Cerebral Vascular Disease
Cerebral vascular disease, which includes conditions such as stroke and transient ischemic attacks (TIAs), is also a macrovascular complication rather than a microvascular one. It involves the blood vessels supplying the brain and is primarily caused by atherosclerosis and hypertension. Diabetes increases the risk of cerebral vascular disease due to its association with other risk factors like high blood pressure and dyslipidemia. However, it is not classified as a microvascular complication.

Correct Answer is B
Explanation
Choice A Reason:
A 42-year-old man with gastroesophageal reflux disease (GERD) is not at the highest risk for obstructive sleep apnea (OSA). While GERD can be associated with OSA, it is not a primary risk factor. The main risk factors for OSA include obesity, age, and anatomical features that can obstruct the airway. Therefore, this individual is not at the greatest risk compared to others.
Choice B Reason:
A 55-year-old woman who is 50 lb (23 kg) overweight is at significant risk for developing OSA. Obesity is one of the most critical risk factors for OSA because excess weight can lead to fat deposits around the upper airway, which can obstruct breathing during sleep. Additionally, being overweight increases the likelihood of other conditions that can exacerbate OSA, such as hypertension and metabolic syndrome.
Choice C Reason:
A 20-year-old woman who is 8 months pregnant may experience temporary sleep disturbances, including snoring and mild sleep apnea, due to hormonal changes and increased abdominal pressure. However, pregnancy-related sleep apnea is usually transient and resolves after childbirth. Therefore, while she may have an increased risk during pregnancy, it is not as significant as the risk posed by obesity.
Choice D Reason:
A 73-year-old man with type 2 diabetes mellitus has an increased risk of OSA, as diabetes is associated with obesity and metabolic syndrome, which are risk factors for OSA. However, the presence of diabetes alone does not pose as high a risk as obesity. Therefore, while this individual is at risk, it is not as high as the risk associated with being significantly overweight.
Correct Answer is C
Explanation
Choice A Reason:
Weigh the client daily: While monitoring weight is important for clients with Addison’s disease, it is not the primary action to prevent an Addisonian crisis. Daily weight monitoring helps track fluid balance and detect any sudden changes that might indicate complications, but it does not directly address the hormonal imbalance that characterizes Addisonian crisis.
Choice B Reason:
Restrict food intake: Restricting food intake is not recommended for clients with Addison’s disease. Proper nutrition is crucial for maintaining energy levels and overall health. Clients with Addison’s disease need a balanced diet to manage their condition effectively. Restricting food intake could lead to malnutrition and exacerbate symptoms.
Choice C Reason:
Administer oral corticosteroids: This is the correct action. Addison’s disease is characterized by insufficient production of cortisol and aldosterone by the adrenal glands. Administering oral corticosteroids helps replace the deficient hormones and manage the symptoms of Addison’s disease. During an Addisonian crisis, immediate administration of corticosteroids is critical to prevent severe complications such as shock, coma, or even death.
Choice D Reason:
Provide a low carbohydrate diet: A low carbohydrate diet is not specifically recommended for clients with Addison’s disease. Instead, a balanced diet that includes adequate carbohydrates, proteins, and fats is essential. Carbohydrates are important for maintaining energy levels, especially since clients with Addison’s disease may experience fatigue and weakness. Restricting carbohydrates could lead to low blood sugar levels, which can be dangerous for these clients.
