A urine sample has a specific gravity of 1.028. What can this result tell you by itself?

  1. A

    It proves the person is dehydrated.

  2. B

    It proves kidney function is normal.

  3. C

    It suggests relatively concentrated urine, but must be interpreted in context.

  4. D

    It measures kidney filtration rate directly.

In a healthy adult, what does a steady-state fluid balance mean?

  1. A

    Intake must always be exactly 2,500 mL per day.

  2. B

    Fluid output must always be greater than intake.

  3. C

    Over time, fluid intake and production balance fluid losses.

Which option correctly matches the main roles of the glomerulus and renal tubule?

  1. A

    The glomerulus reabsorbs needed water; the renal tubule filters blood.

  2. B

    The glomerulus secretes wastes; the renal tubule stores urine.

  3. C

    The glomerulus filters fluid and small solutes from blood; the renal tubule reabsorbs needed substances and secretes some wastes.

  4. D

    Both structures only move finished urine toward the bladder.

  2. B

    They produce digestive enzymes and absorb nutrients from food.

  3. C

    They pump blood and produce red blood cells directly.

  4. D
