Which of the following assessment findings in a client with leukemia would indicate that cancer has invaded the brain?
A. Hypervigilant and anxious behavior
B. Increased heart rate and decreased blood pressure
C. Headache and vomiting
D. Hypervigilant and anxious behavior
Correct Answer: C. Headache and vomiting
Option C: The usual effect of leukemic infiltration of the brain is increased intracranial pressure. The proliferation of cells interferes with the flow of cerebrospinal fluid in the subarachnoid space and at the base of the brain. The increased fluid pressure causes dilation of the ventricles, which creates symptoms of severe headache, vomiting, irritability, lethargy, and eventually, coma.
Option B: Increasing intracranial pressure in brain metastasis would result in symptoms of high blood pressure, decreased pulse rate, and abnormal respirations known as Cushing triad.
Options A and D: Often children with a variety of illnesses are hypervigilant and anxious when hospitalized.
