A client is admitted to the intensive care unit (ICU) with a traumatic brain injury. Which invasive procedure should the nurse anticipate preparing the client to undergo?

Choice A reason: Platelets are unaffected by hydrocortisone in Addison’s disease. Hydrocortisone replaces cortisol, regulating metabolism, not coagulation. Platelet monitoring is relevant for bleeding disorders, not adrenal insufficiency, making this value less critical than glucose, which is directly impacted by cortisol’s gluconeogenic effects.

Choice B reason: Albumin reflects nutritional status but is not directly altered by hydrocortisone. Addison’s disease and hydrocortisone affect glucose and electrolytes via cortisol’s metabolic roles, not protein synthesis. Albumin is secondary, as glucose monitoring addresses immediate metabolic complications of corticosteroid therapy.

Choice C reason: Glucose is critical to monitor, as hydrocortisone increases gluconeogenesis and insulin resistance in Addison’s disease, risking hyperglycemia. Elevated glucose can cause osmotic diuresis or ketoacidosis, requiring dose adjustments or insulin therapy, making this the most important value to ensure safe corticosteroid management.

Choice D reason: Serum electrolytes, like sodium and potassium, are affected by Addison’s, but hydrocortisone primarily corrects hyponatremia and hyperkalemia. Glucose is more critical, as hydrocortisone’s glucocorticoid effects directly raise blood sugar, posing immediate metabolic risks, making this value secondary to glucose monitoring.

Choice A reason: Tracheostomy placement is for prolonged airway management, not immediate in traumatic brain injury (TBI). NGT insertion addresses acute needs like gastric decompression or feeding, as TBI may impair swallowing, making this procedure less urgent than managing intracranial complications.

Choice B reason: Central line insertion provides vascular access but is not specific to TBI. NGT insertion prevents aspiration or manages gastric contents, critical in TBI with altered consciousness, making central lines secondary, as they address fluid or medication needs, not TBI-specific issues.

Choice C reason: NGT insertion is anticipated, as traumatic brain injury often impairs swallowing or consciousness, increasing aspiration risk. The tube decompresses the stomach or delivers nutrition, preventing complications like pneumonia, making it a priority procedure to support TBI management and patient stability.

Choice D reason: Pacemaker placement addresses cardiac arrhythmias, unrelated to traumatic brain injury. NGT insertion manages gastric or nutritional needs in TBI, where neurological deficits are primary, making pacemakers irrelevant, as TBI does not typically involve acute cardiac conduction issues.
