Ch44 Urinary System

A renal stone in the pelvis of the kidney will change kidney function by interfering with the

• structural support of the kidney.

• regulation of the concentration of urine.

• entry and exit of blood vessels at the kidney.

• collection and drainage of urine from the kidney

A patient with kidney disease has oliguria and a creatinine clearance of 40 mL/min. These findings most directly reflect abnormal function of

• tubular secretion.

• glomerular filtration.

• capillary permeability.

• concentration of filtrate.

The nurse identifies a risk for urinary stones in a patient who relates a health history that includes

• hyperaldosteronism.

• serotonin deficiency.

• adrenal insufficiency..

• hyperparathyroidism

Diminished ability to concentrate urine, associated with aging of the urinary system, is attributed to

• a decrease in bladder sensory receptors.

• a decrease in the number of functioning nephrons..

• decreased function of the loop of Henle and tubules.

• thickening of the basement membrane of Bowman’s capsule

During physical assessment of the urinary system, the nurse

• performs fist percussion to detect tenderness in the flank area.

• expects a dull percussion sound when 100 mL of urine is present in the bladder.

• percusses above the symphysis pubis to determine the level of urine in the bladder.

• palpates the lower pole of the right kidney as a smooth mass that descends on expiration.

Normal findings expected by the nurse on physical assessment of the urinary system include (select all that apply)

• nonpalpable bladder.

• nonpalpable left kidney.

• auscultation of renal artery bruit.

• no CVA tenderness elicited by a kidney punch.

• full bladder percusses as dullness above the symphysis pubis.

A diagnostic study that evaluates renal blood flow, glomerular filtration, tubular function, and excretion is a(n)

• IVP.

• VCUG.

• renal scan.

• loopogram

On reading the urinalysis results of a dehydrated patient, the nurse would expect to find

• a pH of 8.4.

• RBCs of 4/hpf.

• color: yellow, cloudy.

• specific gravity of 1.035.
