Exam 3- NUR 221 Kidneys, Urinary System, Male and
Female Reproductive Disorders(Qs & As)
protein Correct-Urea and creatinine are excreted by the kidneys. Urea is the end product
of ____ metabolism.
muscles Correct-Urea and creatinine are excreted by the kidneys. Creatinine is a metabolic
by product that is produced by the ____.
10 Correct-The BUN (Blood-Urea-Nitrogen) to creatinine ration is typically ____ to 1.
0.6-1.2 Correct-When serum creatinine is high the GFR (glomerular filtration rate) is low.
The WNL range for SERUM creatinine is ___ (#.#-#.#) mg/dL.
7-18 Correct-When the BUN (Blood Urea Nitrogen) level rises, the GFR (Glomerular
Filtration Rate) is low. The WNL range for BUN is ____ (#-#) mg/dL.
3.5-5.0 Correct-The WNL range for potassium (K+) is ____ (#.#-#-#) mEq/L.
135-145 Correct-The WNL range for sodium (Na+) is ____ (#-#) mEq/L.
, Exam 3- NUR 221 Kidneys, Urinary System, Male and
Female Reproductive Disorders(Qs & As)
creatinine Correct-A proxy (another way) for determining the glomerular filtration rate
(GFR) is known as ____ clearance. A 24-hour urine specimen is collected to determine this.
afferent Correct-The glomerulus is the first part of the nephron where the blood gets
filtered. Blood enters through the [ afferent / efferent ] arteriole to the proximal tubule and
begins the process of urine formation. The proximal and distal tubules are semi-selective
membranes. Blood and proteins are reabsorbed into the circulation.
urine Correct-The glomerulus is the first part of the nephron where the blood gets filtered.
Blood enters through the afferent arteriole to the proximal tubule and begins the process of
____ formation. The proximal and distal tubules are semi-selective membranes. Blood and
proteins are reabsorbed into the circulation.
kidneys Correct-Urine formation * excretion of waste products * electrolyte, water and
acid-base balance * renal clearance * regulation of RBC prod'n via erythropoietin * synthesis
of active form of vitamin D * secretion of prostaglandins * All of these are key functions of the
____.
, Exam 3- NUR 221 Kidneys, Urinary System, Male and
Female Reproductive Disorders(Qs & As)
hypertension Correct-The nurse knows that diabetes and ____ are major risk factors for
chronic kidney disease.
reabsorption Correct-Urine is formed in the nephrons through a complex three-step
process: glomerular filtration, tubular ____, and tubular secretion. Approximately 180L/day of
filtrate results in 1-2 L of urine.
secretion Correct-Tubular ___ occurs when substances move from the peritubular capillary
(blood) into the tubular lumen (filtrate). It helps with the elimination of K+, H+, ammonia, uric
acid, some drugs and other waste products.
125 Correct-The WNL GFR is ___ (#) mL/min. This is measured by (urine) creatinine
clearance.
decreases Correct-As renal function worsens, the level of creatinine clearance [ decreases /
increases ].
