A nurse is reinforcing teaching with a client who has type 2 diabetes mellitus. The nurse determines that teaching has been effective when the client identifies which of the following manifestations of hypoglycemia? (Select all that apply.)

Choice A: Ketoacidosis. This is incorrect because ketoacidosis is a complication of hyperglycemia, not hypoglycemia. Ketoacidosis occurs when the body breaks down fat for energy due to insufficient insulin, resulting in the accumulation of ketones and acids in the blood. Ketoacidosis can cause symptoms such as nausea, vomiting, abdominal pain, fruity breath odor, deep and rapid breathing, and altered mental status.

Choice B: Hyperglycemia. This is incorrect because hyperglycemia is a condition of high blood glucose, not low blood glucose. Hyperglycemia can occur due to insufficient insulin, excessive carbohydrate intake, infection, stress, or illness. Hyperglycemia can cause symptoms such as polyuria, polydipsia, polyphagia, blurred vision, fatigue, and headache.

Choice C: Hypoglycemia. This is correct because hypoglycemia is a condition of low blood glucose, which can occur due to excessive insulin, inadequate carbohydrate intake, exercise, alcohol consumption, or medication interactions. Hypoglycemia can cause symptoms such as sweating, tachycardia, palpitations, tremors, hunger, anxiety, confusion, dizziness, weakness, and seizures.

Choice D: Nephropathy. This is incorrect because nephropathy is a complication of chronic hyperglycemia, not acute hypoglycemia. Nephropathy is a kidney disease that results from damage to the small blood vessels and glomeruli in the kidneys due to high blood glucose levels. Nephropathy can cause symptoms such as proteinuria, edema, hypertension, and renal failure.

Choice A reason: Weight loss is not a symptom of Cushing’s syndrome. On the contrary, weight gain and obesity are common signs of this condition, especially in the trunk, face and upper back1.

Choice B reason: Diaphoresis, or excessive sweating, is not a symptom of Cushing’s syndrome. It can be caused by other conditions, such as hyperthyroidism, menopause or anxiety.

Choice C reason: Hyperpigmentation, or darkening of the skin, is a symptom of Cushing’s syndrome. It occurs due to increased production of melanin, the pigment that gives color to the skin. Hyperpigmentation can affect any part of the body, but it is more noticeable in areas exposed to friction or pressure, such as the elbows, knees, knuckles and armpits.

Choice D reason: Hypotension, or low blood pressure, is not a symptom of Cushing’s syndrome. In fact, high blood pressure (hypertension) is one of the common symptoms of this condition, due to the effects of cortisol on the cardiovascular system.
