A nurse is reinforcing teaching for a client who has type 1 diabetes mellitus about foot care. Which of the following client statements should indicate to the nurse an understanding of the instructions?

Choice A reason: Injecting insulin into a muscle that is going to be exercised can increase the absorption of insulin and lower the blood glucose level, leading to hypoglycemia. Therefore, it is advisable to avoid injecting insulin into the same body part that will be involved in the exercise.

Choice B reason: Carrying a complex carbohydrate snack with you when you exercise is not a good idea. Complex carbohydrates take longer to digest and raise the blood glucose level slowly. They are not suitable for treating or preventing hypoglycemia during or after exercise. A simple carbohydrate snack, such as glucose tablets, juice or candy, is more appropriate for this purpose.

Choice C reason: Exercising first thing in the morning before eating breakfast is not recommended for people with type 1 diabetes. This can cause a drop in blood glucose level and increase the risk of hypoglycemia. It is beter to have a balanced breakfast that includes some carbohydrates and adjust the insulin dose accordingly before exercising.

Choice D reason: Increasing the intensity of your exercise routine if your urine is positive for ketones is a dangerous practice. Ketones are produced when the body breaks down fat for energy due to lack of insulin or glucose. High levels of ketones can lead to diabetic ketoacidosis, a life-threatening condition that requires urgent medical atention. Intense exercise can raise the blood glucose level further and worsen the situation. If your urine is positive for ketones, you should avoid vigorous activity and check your blood glucose and ketone levels frequently.

Choice A: Both illnesses result in malabsorption of nutrients. This is incorrect because malabsorption of nutrients is more common in Crohn’s disease than in ulcerative colitis. Crohn’s disease can affect any part of the gastrointestinal tract, including the small intestine, where most of the nutrient absorption occurs. Ulcerative colitis mainly affects the colon and rectum, which are responsible for water and electrolyte absorption.

Choice B: Both illnesses begin in the rectum. This is incorrect because ulcerative colitis usually begins in the rectum and spreads proximally to the colon, while Crohn’s disease can begin anywhere in the gastrointestinal tract, from the mouth to the anus.

Choice C: Both illnesses manifest fistula formation. This is incorrect because fistula formation is more common in Crohn’s disease than in ulcerative colitis. Fistulas are abnormal connections between different parts of the gastrointestinal tract or other organs, such as the bladder, vagina, or skin. They are caused by inflammation, ulceration, and infection that penetrate through the bowel wall.

Choice D: Both illnesses are inflammatory in nature. This is correct because both ulcerative colitis and Crohn’s disease are types of inflammatory bowel disease (IBD), which are chronic conditions that cause inflammation and damage to the gastrointestinal tract. The exact cause of IBD is unknown, but it may involve genetic, immune, environmental, and microbial factors.
