A child has been diagnosed with a midline brain tumor. In addition to showing signs of increased intracranial pressure (ICP), she has been voiding large amounts of very dilute urine. Which medication dothe nurse expect to administer?

Correct Answer: B

Rationale: Vasopressin is expected for a midline brain tumor with increased ICP and dilute polyuria, per endocrinology texts. This suggests diabetinsipidus (DI) from pituitary/hypothalamic disruption, common in midline tumors (e.g., craniopharyngioma). Vasopressin replacdeficient ADH, reducing urine output and stabilizing fluid balance. Mannitol and Lasix treat ICP but worsen DI dehydration; dopamine supports BP, not DI. Bs specificity to DI, a frequent tumor complication, makes itthe correct answer, addressing the underlying pathophysiology.

Correct Answer: A

Rationale: Follow up with the pediatrician for a likely atonic seizure is best, per epilepsy texts. Sudden falls with brief weakness suggest atonic seizur(tone loss), needing evaluation. Stressors dont fit; absence lacks falls; growth dismisssymptoms. As specificity makes itthe correct answer.

Correct Answer: D

Rationale: A reflex from overstimulation is best, per neurology texts. Flexion toward midline (decorticate-like) in an unconscious child suggests a reflex to excessive stimuli, not purposeful response (A, B) or seizure . Ds explanation makes itthe correct answer.

Correct Answer: A

Rationale: Brudzinski sign is neck flexion causing knee/hip flexion in meningitis, per infectious disease texts, indicating meningeal irritation. Cushing is ICP triad; Kernig leg extension pain; nuchal stiffness. As specificity makes itthe correct answer.

Correct Answer: D

Rationale: Dark, quiet with minimal stimulation is most appropriate for unconsciousness with ICP, per neurocritical care, reducing oxygen demand and ICP spikes. Stimulation (A, B) or day/night cycling worsens it. Ds focus makes itthe correct answer.
