Answer to Question 1

ANS: A
The transmission of ultrasonic waves through the renal parenchyma allows visualization of the renal parenchyma and renal pelvis without exposure to external-beam radiation or radioactive isotopes. Computed tomography uses external radiation, and sometimes contrast media are used. Intravenous pyelography uses contrast medium and external radiation for radiography. Contrast medium is injected into the bladder through the urethral opening. External radiation for radiography is used before, during, and after voiding in voiding cystourethrography.

Answer to Question 2

ANS: A
The expected pH ranges from 4.8 to 7.8. A pH of 4.0 can be indicative of urinary tract infection or metabolic alkalosis or acidosis. Less than 1 or 2 white blood cells per milliliter is the expected range. The absence of protein is expected. The presence of protein can be indicative of glomerular disease. A specific gravity of 1.020 is within the anticipated range of 1.001 to 1.030. Specific gravity reflects level of hydration in addition to renal disorders and hormonal control such as antidiuretic hormone.
