A nurse teaches a client with diabetes mellitus about sick day management. Which statement should the nurse include in this client's teaching?

Choice A rationale: Atherosclerosis is a common complication of diabetes, but it's a macrovascular complication, not a direct result of diabetic neuropathy. Neuropathy affects the nerves, while atherosclerosis involves the hardening and narrowing of arteries due to plaque buildup, which is a separate but related long-term complication of hyperglycemia. Choice B rationale: Diabetic retinopathy is a microvascular complication of diabetes that affects the blood vessels in the retina of the eye. It is not caused by neuropathy. Neuropathy affects peripheral nerves, leading to sensory, motor, or autonomic dysfunction, and is a distinct complication of diabetes. Choice C rationale: Diabetic neuropathy, particularly peripheral sensory neuropathy, causes a loss of protective sensation in the feet. Patients cannot feel pain, pressure, or temperature, making them unaware of injuries, blisters, or cuts. This lack of sensation places them at high risk for undetected foot injuries, which can lead to ulcers, infections, and even amputation. Choice D rationale: Kidney failure is a complication of diabetic nephropathy, which involves damage to the small blood vessels in the kidneys (glomeruli). It is not a direct result of diabetic neuropathy. While both are microvascular complications of diabetes, they affect different organ systems and have different pathophysiological mechanisms.

Choice A rationale: Gestational diabetes mellitus is a condition characterized by hyperglycemia first recognized during pregnancy. It is caused by hormonal changes that lead to insulin resistance. This type of diabetes typically resolves after childbirth, although it increases a woman's risk for developing type 2 diabetes later in life. It is not necessarily associated with aging.
Choice B rationale: Immune-mediated diabetes mellitus is another name for type 1 diabetes, where the body's immune system destroys the insulin-producing beta cells in the pancreas. This leads to an absolute insulin deficiency. It can occur at any age, but is most commonly diagnosed in children and young adults, and is not associated with obesity.
Choice C rationale: Type 1 diabetes mellitus is an autoimmune disease resulting from the destruction of pancreatic beta cells, causing an absolute insulin deficiency. It is not typically associated with obesity or aging, and patients with this condition always require insulin therapy for survival to regulate their blood glucose levels.
Choice D rationale: Type 2 diabetes mellitus is a metabolic disorder characterized by insulin resistance and relative insulin deficiency. It is strongly associated with lifestyle factors like obesity and physical inactivity, and its prevalence increases with age. While many patients manage it with diet and oral medications, some may eventually require insulin therapy as the disease progresses.
