Question

an instrument used to measure the specific properties of urine is an:
a urinometer
b urethroscope
c urethrometer
d ureterogram

question 6

an incision into the renal pelvis to remove a stone would be known as:
a pyelostomy
b pyelolithotomy
c pyeloplasty
d pyelorrhaphy

Explanation:

First Question (Instrument to measure urine properties)

• Option A: A urinometer is specifically designed to measure properties of urine (like specific gravity).
• Option B: A urethroscope is used to examine the urethra, not measure urine properties.
• Option C: Urethrometer is not a standard instrument for urine property measurement (focuses on urethra, likely a distractor).
• Option D: Ureterogram is an imaging procedure, not a measuring instrument.

• Option A: Pyelostomy is creating a stoma in the renal pelvis, not for stone removal.
• Option B: Pyelolithotomy breaks down to "pyelo-" (renal pelvis), "litho-" (stone), "tomy" (incision) – matches the description of incising renal pelvis to remove a stone.
• Option C: Pyeloplasty is for reconstructing the renal pelvis, not stone removal.
• Option D: Pyelorrhaphy is suturing the renal pelvis, not for stone removal.

Answer:

A. urinometer
