A postoperative patient who had surgery for a perforated gastric ulcer has been receiving nasogastric suction for 3 days. The patient now has a serum sodium level of 127 mEq/L (127 mmol/L). Which prescribed therapy should the nurse question?

Choice A reason: Weight loss is a common clinical manifestation of type 1 diabetes mellitus in children. Type 1 diabetes mellitus is a condition where the pancreas does not produce enough insulin, a hormone that helps the cells use glucose for energy. Without insulin, the glucose stays in the blood and causes high blood sugar levels. The body then breaks down fat and muscle for energy, resulting in weight loss.

Choice B reason: Low urine output is not a typical clinical manifestation of type 1 diabetes mellitus in children. In fact, the opposite is true: high urine output is a sign of type 1 diabetes mellitus. This is because the excess glucose in the blood draws water from the cells and tissues, causing dehydration and increased thirst. The kidneys then try to flush out the glucose and water through urine, leading to frequent urination.

Choice C reason: Weight gain is not a usual clinical manifestation of type 1 diabetes mellitus in children. As explained in choice A, type 1 diabetes mellitus causes weight loss due to the lack of insulin and the breakdown of fat and muscle. Weight gain can be a sign of type 2 diabetes mellitus, which is a condition where the cells become resistant to insulin and the pancreas cannot produce enough insulin to overcome the resistance. Weight gain can also be a side effect of insulin therapy, which is used to treat both types of diabetes mellitus.

Choice D reason: Hand tremors are not a specific clinical manifestation of type 1 diabetes mellitus in children. Hand tremors can be caused by many factors, such as anxiety, stress, caffeine, medication, or neurological disorders. Hand tremors can also be a symptom of hypoglycemia, which is a condition of low blood sugar that can occur in people with diabetes mellitus. However, hypoglycemia is not exclusive to diabetes mellitus, and can affect anyone who has a low intake of food, a high expenditure of energy, or a high dose of insulin or oral hypoglycemic agents.

Choice A reason: This statement is true. Distended neck veins are a sign of fluid volume overload, as they indicate increased central venous pressure and right-sided heart failure.

Choice B reason: This statement is false. Hypotension is a sign of fluid volume deficit, not fluid volume overload. Hypotension occurs when the blood pressure is too low to perfuse the vital organs.

Choice C reason: This statement is false. Increased serum osmolality is a sign of fluid volume deficit, not fluid volume overload. Increased serum osmolality occurs when the blood concentration of solutes, such as sodium and glucose, is too high due to fluid loss.

Choice D reason: This statement is false. Dry oral mucosa is a sign of fluid volume deficit, not fluid volume overload. Dry oral mucosa occurs when the oral cavity is dehydrated due to fluid loss.

Choice E reason: This statement is true. Decreased urine specific gravity is a sign of fluid volume overload, as it indicates diluted urine and impaired kidney function.

Choice F reason: This statement is true. Weight gain is a sign of fluid volume overload, as it indicates fluid retention and edema.

Choice G reason: This statement is false. Sunken anterior fontanelle is a sign of fluid volume deficit, not fluid volume overload. Sunken anterior fontanelle occurs when the soft spot on the baby's head is depressed due to fluid loss.
