They activate renal parasympathetic neurons and cause mild vasoconstriction.

 

 

They activate renal sympathetic neurons and cause mild vasoconstriction.

They activate renal sympathetic neurons and cause mild vasodilation.

Inhibition of renin and aldosterone

 

Question 5 (0.5 points) Question 5 Saved

What is the direct action of atrial natriuretic hormone?

 

Question 5 options:

 

Sodium retention

 

 

Sodium excretion

 

 

Water retention

 

 

Water excretion

 

Question 6 (0.5 points) Question 6 Unsaved

Which term is used to identify the movement of fluids and solutes from the tubular lumen to the peritubular capillary plasma?

 

Question 6 options:

 

Tubular secretion

 

 

Ultrafiltration

 

 

Tubular reabsorption

 

 

Tubular excretion

 

Question 7 (0.5 points) Question 7 Unsaved

Which statement is true regarding urodilatin?

 

Question 7 options:

 

Urodilatin inhibits sodium chloride and water reabsorption in the medullary part of the collecting duct.

 

 

Urodilatin inhibits antidiuretic hormone (ADH) to prevent water reabsorption in the medullary part of the collecting duct.

 

 

Urodilatin is stimulated by a rise in blood pressure and an increase in extracellular volume.

 

 

Urodilatin is stimulated by a fall in blood pressure and a decrease in extracellular volume.

 

Question 8 (0.5 points) Question 8 Unsaved

Compared to a younger individual, how is the specific gravity of urine in older adults affected?

 

Question 8 options:

 

The specific gravity of urine in older adults is increased.

 

 

The specific gravity of urine in older adults is considered high normal.

 

 

The specific gravity of urine in older adults is considered low normal.

 

 

The specific gravity of urine in older adults is decreased.

 

Question 9 (0.5 points) Question 9 Unsaved

How are glucose and insulin used to treat hyperkalemia associated with acute renal failure?

 

Question 9 options:

 

Glucose has an osmotic effect, which attracts water and sodium, resulting in more dilute blood and a lower potassium concentration.

 

 

When insulin transports glucose into the cell, it also carries potassium with it.

 

 

Potassium attaches to receptors on the cell membrane of glucose and is carried into the cell.

 

 

Increasing insulin causes ketoacidosis, which causes potassium to move into the cell in exchange for hydrogen.

 

Question 10 (0.5 points) Question 10 Unsaved

Which statement is false concerning the skeletal alterations caused by chronic renal failure when the glomerular filtration rate (GFR) declines to 25% of normal?

 

Question 10 options:

 

Parathyroid hormone is no longer effective in maintaining serum phosphate levels.

 

 

The parathyroid gland is no longer able to secrete sufficient parathyroid hormone.

 

 

The synthesis of 1,25-dihydroxyvitamin D3, which reduces intestinal absorption of calcium, is impaired.

 

 

The synthesis of 1,25-dihydroxyvitamin D3, which impairs the effectiveness of calcium and phosphate resorption from bone by parathyroid hormone, is impaired.

 

Question 11 (0.5 points) Question 11 Unsaved

Anemia of chronic renal failure can be successfully treated with which element?

 

Question 11 options:

 

Intrinsic factor

 

 

Vitamin B12

 

 

Vitamin D

 

 

Erythropoietin

 

Question 12 (0.5 points) Question 12 Unsaved

Acute glomerulonephritis (AGN) may be accompanied by a positive throat or skin culture for which bacteria?

 

Question 12 options:

 

Staphylococcus aureus

 

 

Streptococcus

 

 

Pseudomonas aeruginosa

 

 

Haemophilus

 

Question 13 (0.5 points) Question 13 Unsaved

What is the cause of smoky, brown-colored urine resulting from acute poststreptococcal glomerulonephritis?

 

Question 13 options:

 

Presence of red blood cells

 

 

Presence of urobilinogen

 

 

Slough from the collecting tubules

 

 

Protein in the urine

 

Question 14 (0.5 points) Question 14 Unsaved

What is the pathophysiologic process responsible for the autoimmune disorder of hemolytic-uremic syndrome (HUS)?

 

Question 14 options:

 

Immunoglobulin A (IgA) coats erythrocytes that are destroyed by the spleen, and remnants are excreted through the kidneys.

 

 

Verotoxin from Escherichia coli (E. coli) is absorbed from the intestines and damages erythrocytes and endothelial cells.

 

 

Endotoxins from E. coli block the erythropoietin produced by the kidneys, which reduces the number of erythrocytes produced by the bone marrow.

 

 

Failure of the nephrons to filter urea increases the blood urea nitrogen (BUN), which binds to erythrocytes that are subsequently destroyed by the spleen.

 

Question 15 (0.5 points) Question 15 Unsaved

What is the first indication of nephrotic syndrome in children?

 

Question 15 options:

 

Periorbital edema

 

 

Scrotal or labial edema

Question 16 options:

 

Systemic blood that is filtered through the kidney

 

 

Bacteria traveling from the lymph adjacent to the bladder and kidneys

 

 

Bacteria ascending the urethra into the bladder

 

 

Colonization of the bladder when urine is static

 

Question 17 (0.5 points) Question 17 Unsaved

What causes vesicoureteral reflux to occur in children?

 

Question 17 options:

 

Children do not ask for help in urinating in a timely manner, and urine is forced up into the ureters.

 

 

The submucosal segment of a child’s ureter is short, making the antireflux mechanism inefficient.

 

 

The trigone lying between the opening to the ureters and the urethra is underdeveloped in children.

 

 

As the bladder fills in infants and children, it pulls the smooth lining of the transitional epithelium away from the ureters, making the reflux valves ineffective.

 

Question 18 (0.5 points) Question 18 Unsaved

What is the mechanism for developing Wilms’ tumor?

 

Question 18 options:

 

The development of Wilms’ tumor involves tumor suppressor genes located on chromosome 11.

 

 

Development involves an autosomal dominant inherited disorder involving the Y chromosome.

 

 

Wilms’ tumor is an autoimmune disorder.

 

 

The development of Wilms’ tumor is a congenital anomaly.

A maturational lag may cause enuresis.

 

 

Enuresis may be related to increased light sleep.

 

 

Obstructive sleep apnea may be a symptom of enuresis.
