The metabolic and nutritional needs of a patient with increased ICP are best met by:

• A. Enteral feedings that are low in sodium.
• B. D5W (5% dextrose) glucose solution.
• C. A fluid restriction that promotes moderate dehydration.
• D. Balanced, essential nutrition in a form the patient can tolerate.

Answer: (D)

When ICP is elevated, the brain’s energy needs rise and even small shifts in fluids or electrolytes can worsen edema or cerebral perfusion. The best approach is to provide balanced, essential nutrition in a form the patient can tolerate, so the brain gets fuel and the body preserves lean mass without introducing osmotic or fluid disturbances that could aggravate swelling. Delivering nutrition enterally, if the gut works, is preferred because it provides complete calories and protein while supporting gut integrity and immune function. A well-rounded formula supplies carbohydrates, protein, fats, vitamins, and minerals in proportions that help meet metabolic demands without overstressing fluid balance or causing dangerous glucose or electrolyte swings. This approach helps prevent catabolism, supports healing, and allows careful management of glucose and sodium levels to avoid osmotic shifts that could worsen edema or reduce cerebral perfusion. The other options carry risks in this context. A feed low in sodium could contribute to hyponatremia, increasing cerebral edema risk. D5W is a hypotonic solution after the glucose is metabolized and can dilute serum sodium and add free water, potentially worsening ICP. Restricting fluids to promote dehydration lowers cerebral perfusion and can harm brain tissue. In contrast, balanced, tolerable nutrition addresses caloric and protein needs safely, supporting brain metabolism and overall recovery.
