A child is admitted with circumferential burns of the left arm. Following the initial assessment, what is the most urgent intervention the nurse should anticipate to prevent complications such as compartment syndrome?

Hypercalcemia is a condition characterized by elevated serum calcium levels, which can affect neuromuscular, renal, and neurological function. Common manifestations include confusion, lethargy, dehydration, and increased thirst. Severe cases can lead to cardiac dysrhythmias and decreased level of consciousness. Management focuses on promoting calcium excretion, maintaining hydration, and preventing complications such as renal calculi and further neurological decline.

Rationale:
A. Encouraging fluid intake of 3 L daily is the priority intervention because increased hydration enhances renal perfusion and promotes urinary excretion of excess calcium. Fluids help dilute serum calcium levels and reduce the risk of kidney stone formation. Adequate hydration is one of the most effective initial strategies for managing mild to moderate hypercalcemia.

B. Obtaining blood cultures is not indicated because hypercalcemia is not primarily caused by infection. Blood cultures are used to identify bloodstream infections and guide antibiotic therapy, which is unrelated to the management of elevated calcium levels. The client’s symptoms are metabolic rather than infectious in origin.

C. Administering high-dose IV corticosteroids is not the first-line intervention for hypercalcemia. While steroids may be used in specific conditions such as malignancy-related hypercalcemia or vitamin D–mediated cases, they are not the immediate priority. Initial management focuses on hydration and promoting calcium elimination before pharmacologic escalation.

D. Placing the client in a flat position is inappropriate and does not address hypercalcemia. Positioning does not influence calcium levels or enhance renal excretion. Additionally, a flat position may worsen comfort in a confused or lethargic client and does not contribute to correcting the underlying metabolic imbalance.

Severe cirrhosis impairs the liver’s ability to detoxify ammonia, a byproduct of protein metabolism, leading to hyperammonemia and hepatic encephalopathy. Dietary management is an important supportive strategy in reducing ammonia load and preventing neurologic deterioration. In advanced liver disease, protein metabolism must be carefully balanced to minimize toxin buildup while still supporting essential body functions. Nutrition adjustments therefore focus on controlling protein intake rather than eliminating overall nutrition.

Rationale:
A. Increasing protein intake to promote healing and recovery is inappropriate in severe cirrhosis with elevated ammonia levels. Excess protein metabolism increases ammonia production, which the damaged liver cannot effectively convert into urea. This can worsen hepatic encephalopathy, leading to confusion, lethargy, and decreased level of consciousness.

B. Incorporating high-fiber foods is beneficial for bowel health, but stopping lactulose is unsafe in this context. Lactulose helps reduce ammonia by trapping it in the gut and promoting its excretion through stool. Discontinuing it would allow ammonia levels to rise, worsening neurologic symptoms.

C. Reducing protein intake to minimize ammonia production during digestion is the priority dietary modification. Protein breakdown produces nitrogenous waste, including ammonia, which accumulates in cirrhosis due to impaired hepatic detoxification. Controlled protein restriction helps lower ammonia levels and reduces the risk of hepatic encephalopathy exacerbation while still maintaining adequate nutrition.

D. Eliminating carbohydrates completely is not appropriate because carbohydrates are an essential energy source for clients with liver disease. Removing carbohydrates can lead to muscle breakdown for energy, which paradoxically increases ammonia production. A balanced diet with adequate calories from carbohydrates is necessary to prevent catabolism and further metabolic stress.
