  • 4. 

    Extracellular fluid in adults differs from intracellular fluid in that its Tonicity is lower.  

    • True

    • False

    Correct Answer
    A. False
    Explanation
    False It is the same; if it were lower, osmosis would draw water into the cells.

    Correct Answer
    A. True
    Explanation
    True Around 30:1; the intracellular ratio is about 1:10.

    A 49-year-old male in end-stage renal failure is able to perform peritoneal dialysis at home. The osmolality of the solution chosen for peritoneal dialysis will determine the rate of ultrafiltration. Which of the following statements best characterizes a molecule whose osmolality is zero?  

    • A. It will not permeate the membrane

    • B. It can only cross the membrane through the lipid bilayer

    • C. It causes water to flow across the membrane

    • D. It is as diffusible through the membrane as water

    • E. It is transported across the membrane by a carrier

    Correct Answer
    A. D. It is as diffusible through the membrane as water
    Explanation
    The answer is D. The osmolality of a substance is the number of osmoles per kg of solvent. One osmole (Osm) equals the gram molecular weight of a substance divided by the number of free moving particles that each molecule liberates in solution. Osmotically active substances in the body are dissolved in water, and the density of water is 1.
    Thus, osmolar concentrations can be expressed as osmoles (or milliosmoles) per liter of water. If the osmolality is zero, there are no free moving particles, and thus, the molecule is as diffusible as water through the membrane

    In error, a patient is infused with large volumes of a solution that causes lysis of his red blood cells (RBCs). The solution was most likely  

    • (A) isotonic NaCl

    • (B) isotonic mannitol

    • (C) hypertonic mannitol

    • (D) hypotonic urea

    • (E) hypertonic urea

    Correct Answer
    A. (D) hypotonic urea
    Explanation
    The answer is D. Lysis of the patient's red blood cells (RBCs) was caused by entry of water and swelling of the cells to the point of rupture. Water would flow into the RBCs if the extracellular fluid became hypotonic (had a lower osmotic pressure) relative to the intracellular fluid—hypotonic urea. By definition, isotonic solutions do not cause water to flow into or out of cells because the osmotic pressure is the same on both sides of the cell membrane. Hypertonic mannitol would cause shrinkage of the RBCs.

    The diagram below illustrates the concentration of a substance in two chambers. If the concentration of the substance in chamber A doubles, the diffusion of the substance will change from 10 mg/h to which of the following?   - ProProfs

    The diagram below illustrates the concentration of a substance in two chambers. If the concentration of the substance in chamber A doubles, the diffusion of the substance will change from 10 mg/h to which of the following?  

    • E 30 mg/h

    • A. 5 mg/h

    • B 10 mg/h

    • C 15 mg/h

    • D 20 mg/h

    Correct Answer
    A. E 30 mg/h
    Explanation
    The answer is E. Fick’s law states that the net rate of diffusional flux (J) of a substance is proportional to its concentration difference (Δc). Doubling the concentration of the substance in chamber A from 20 to 40 mg/L, causes the concentration difference to increase by threefold from 10 to 30 mg/L. Therefore, the net rate of diffusion would increase from 10 to 30 mg/h.
