A patient with diabetes is starting on insulin therapy. Which type of insulin will the nurse discuss using for mealtime coverage?

Choice A reason: Eating a piece of pizza is not a good option for the student. Pizza is a complex carbohydrate that contains fat and protein, which can delay the absorption of glucose and cause unpredictable blood sugar levels. The student needs a simple carbohydrate that can quickly raise her blood sugar level, such as glucose tablets, fruit juice, or candy.

Choice B reason: Taking an extra dose of rapid-acting insulin is a dangerous option for the student. Insulin lowers the blood sugar level, and the student already has symptoms of hypoglycemia (low blood sugar), such as headache, vision changes, and anxiety. Taking more insulin can worsen her condition and cause seizures, coma, or death.

Choice C reason: Eating 15 g of simple carbohydrates is the best option for the student. Simple carbohydrates are easily digested and absorbed into the bloodstream, and can raise the blood sugar level within 15 minutes. The student should eat 15 g of simple carbohydrates, such as four glucose tablets, half a cup of fruit juice, or three pieces of hard candy, and then check her blood sugar level if possible.

Choice D reason: Drinking some diet pop is not a helpful option for the student. Diet pop does not contain any sugar or calories, and will not affect the blood sugar level. The student needs a source of glucose to treat her hypoglycemia, and diet pop will not provide that.

Choice A reason: Burning pain and tingling in extremities are not symptoms of autonomic neuropathy, but of peripheral neuropathy. Peripheral neuropathy affects the sensory and motor nerves that innervate the skin, muscles, and joints. It can cause pain, numbness, weakness, and loss of sensation in the extremities. Autonomic neuropathy affects the nerves that control the involuntary functions of the body, such as digestion, blood pressure, heart rate, and sweating.

Choice B reason: Nausea and feeling of abdominal fullness are symptoms of autonomic neuropathy, specifically of gastroparesis. Gastroparesis is a condition where the stomach muscles are weakened or paralyzed, and cannot move food properly. It can cause delayed gastric emptying, nausea, vomiting, bloating, early satiety, and poor blood glucose control. Autonomic neuropathy can damage the vagus nerve, which regulates the stomach motility and secretion.

Choice C reason: Elevated blood pressure and delayed capillary refill are not symptoms of autonomic neuropathy, but of cardiovascular problems. Blood pressure is the force of blood against the walls of the arteries, and capillary refill is the time it takes for the color to return to the nail bed after pressing on it. Elevated blood pressure can indicate hypertension, which is a risk factor for heart disease and stroke. Delayed capillary refill can indicate poor blood circulation, which can be caused by atherosclerosis, peripheral artery disease, or shock. Autonomic neuropathy can affect the blood pressure and heart rate, but usually causes hypotension and tachycardia, not hypertension and delayed capillary refill.

Choice D reason: Increased thirst and excessive urination are not symptoms of autonomic neuropathy, but of diabetes mellitus. Diabetes mellitus is a condition where the body cannot produce or use insulin properly, and the blood glucose level becomes too high. Increased thirst and excessive urination are signs of hyperglycemia, which is a high blood glucose level. Hyperglycemia can cause dehydration, electrolyte imbalance, and ketoacidosis. Autonomic neuropathy can be a complication of diabetes mellitus, but it does not cause increased thirst and excessive urination.
