A 13-year-old patient is admitted to the adolescent unit with a suspected brain tumor. The patient asks the nurse which diagnostic test is the most helpful in the diagnosis of brain tumors. What is the nurse's best response?
A) Computed tomography (CT) scan
B) Magnetic resonance imaging (MRI)
C) Brain biopsy
D) Blood work with (ACTH) levels
Ans: B
Feedback: An MRI is the most helpful in the diagnosis of brain tumors. Its use has resulted in the detection of smaller lesions; it is particularly helpful in detecting tumors in the brainstem and pituitary regions, where bone interferes with CT. A brain biopsy and blood work with ACTH levels do not diagnose brain tumors.
