What are the complications of untreated hyperglycemia?

Correct Answer: A

Rationale: The correct answer is A: Diabetic ketoacidosis and dehydration. Untreated hyperglycemia can lead to diabetic ketoacidosis, a serious complication characterized by high blood sugar, the presence of ketones in the urine, and acidosis. Dehydration is also a common complication of untreated hyperglycemia. Choices B, C, and D are incorrect because hypoglycemia and hypertension are not typical complications of untreated hyperglycemia. Infection and liver failure, as well as pulmonary edema and electrolyte imbalance, are also not direct complications of untreated hyperglycemia.

Correct Answer: A

Rationale: The correct answer is A. Common complications of diabetes include retinopathy (damage to the retina) and nephropathy (kidney damage). These complications can be managed effectively with regular screening to detect any signs early on. Choice B is incorrect as neuropathy and cardiovascular disease are other complications of diabetes but are managed through various treatments and lifestyle modifications, not just medication. Choice C is incorrect as although foot ulcers and hypertension are associated with diabetes, the management involves proper foot care practices and blood pressure control, respectively. Choice D is incorrect as hypertension and liver disease are not the typical complications of diabetes, and insulin therapy is not the primary management for these conditions.

Correct Answer: A

Rationale: The correct answer is A: Electrolyte imbalance and dehydration. Diabetic ketoacidosis can lead to imbalances in electrolytes such as potassium, sodium, and chloride, as well as dehydration due to excess urination and vomiting. These complications should be managed promptly with appropriate fluids and insulin. Choices B, C, and D are incorrect. Hypoglycemia and increased urination are not typical complications of diabetic ketoacidosis; kidney failure and respiratory distress may occur in severe cases but are not the primary complications. Liver failure and hypertension are not directly associated with diabetic ketoacidosis.

Correct Answer: A

Rationale: The correct answer is A: Excessive thirst and fruity breath odor. Diabetic ketoacidosis presents with these early signs due to ketone buildup in the body. Choice B, weight loss and increased urination, are more characteristic of uncontrolled diabetes but not specific to diabetic ketoacidosis. Choice C, nausea and vomiting, can occur in diabetic ketoacidosis but are not as early or specific as excessive thirst and fruity breath odor. Choice D, hypoglycemia and fatigue, are not typical signs of diabetic ketoacidosis; rather, diabetic ketoacidosis usually presents with hyperglycemia.

Correct Answer: A

Rationale: The correct nursing intervention for a patient with a pressure ulcer is to clean the wound and apply a hydrocolloid dressing. This promotes healing by creating a moist environment conducive to the wound healing process. Choice B is incorrect because while nutrition is important for wound healing, a high-protein diet alone is not a specific intervention for a pressure ulcer. Choice C is incorrect as antibiotics are only used if there is an infection present. Choice D is also incorrect as a low-sodium diet and monitoring for fluid retention are more related to conditions like heart failure or kidney disease, not specifically pressure ulcer care.
