Answer to Question 1

D
Explanation: Cerebral angiography is an X-ray of the blood vessels of the brain after an injection of radiopaque dye. A nerve conduction velocity test measures how fast an impulse travels along a nerve. A lumbar puncture is a puncture with a needle into the lumbar area to withdraw fluid for examination and for the injection of anesthesia. Positron emission tomography uses positively charged isotopes to image the brain's metabolically active tissue.

Answer to Question 2

C
Explanation: Nephr/o means kidney and -oma means tumor, so nephroma means kidney tumor. -osis means abnormal condition; therefore, nephrosis means abnormal condition of the kidney. -pathy means disease; thus, nephropathy means kidney disease. -megaly means enlarged; hence, nephromegaly means enlarged kidney.
