Chapter 3, Problem 3ACQ
Figure 3.22 A doctor injects a patient with what he thinks is isotonic saline solution. The patient dies, and autopsy reveals that many red blood cells have been destroyed. Do you think the solution the doctor injected was really isotonic?

red blood cells in that situation?

Intravenous solutions must be prepared so that they are isotonic to red blood cells. A 0.9% salt solution is isotonic. What will happen to a red blood cell placed in a 0.6% salt solution?
In the following diagram, identify the type of solution (hypertonic, hypotonic, or isotonic) in which each red blood cell is immersed.

- If a doctor injected a patient with what was labeled as an isotonic saline solution, but then the patient died, and an autopsy revealed that several of the patient's red blood cells had burst, such as in the image on the right, would it be true that the injected solution was really isotonic? Why or why not?arrow_forwardA patient has had a serious accident and lost a lot of blood. In an attempt to replenish body fluids, a large amount of distilled water was transferred directly into one of his veins. What will be the most probable result of this transfusion? It will have serious, perhaps fatal, consequences because the red blood cells will be hypertonic relative to the body fluids and the cells will burst. It will have serious, perhaps fatal, consequences because the red blood cells will be hypotonic relative to the body fluids and the cells will shrivel. It will have no unfavorable effect as long as the water is free of viruses and bacteria. It will have no serious effect because the kidneys would quickly eliminate the excess water. It will have serious, perhaps fatal, consequences because there will be too much fluid for the heart to pump.arrow_forwardIsotonic saline and 5% dextrose in water are solutions considered isotonic to human blood. What effect on red blood cells would you expect if a patient were given these fluids intravenously? A solution of 10% dextrose in water is hypertonic to human blood.arrow_forward
- Which answer is correct (a or b) for the question about why your hands and feet get wrinkled after staying in the bath for too long. a) the water and dissolved particles are drawn out of your skin by diffusion into the large body of water around you. b) the water is actually drawn into your skin by osmosis. explain why (a or b) is correct.arrow_forwardIsotonic, hypotonic, and hypertonic IV (intravenous) fluid solutions are widely used in the healthcare setting. As a possible health care professional, you must know how each of the solutions work on the body and why they are given. a) When does each type of solution must be applied to a patient? b) What does each type of solution do the cells? Isotonic IV fluid solution Hypotonic IV fluid solution Hypertonic IV fluid solution|arrow_forwardInflammatory responses are associated with lots of swelling, where fluids rush into cells and surrounding tissues. To help quickly relieve swelling, what type of IV solution could a doctor administer to her patient? hypotonic hypertonic isotonicarrow_forward
- Your friend notes that Gatorade has electrolytes like sodium and potassium chloride. He figures that if a few electrolytes are good for you, then a lot must be even better. Following this logic, he adds nearly a tablespoonful of salt to his Gatorade. What kind of solution is his Gatorade now (hypotonic, isotonic, or hypertonic)? What will likely happen to his cells if he drinks this liquid?arrow_forwardWhy is it important to know the isotonic point of human cells when administering an IV? Explain what would happen to the red blood cells if an IV solution were hypotonic or hypertonic.arrow_forwardIn medicine, why is it important to administer only isotonic intravenous solutions to patients? Example of isotonic IV fluids are normal saline and lactated Ringer’s solution.arrow_forward
- You are a doctor in the emergency room. You have a patient whose blood cells are composed of the following: 80 molecules of glucose, 50 molecules of hemoglobin, 20 molecules of dextrose, and 2000 molecules of water. a. What is the total solute concentration of her cells? b. If you needed to make an isotonic solution of saline for her IV, how many salt molecules would you need to add to 1000 molecules of water? How do you know this is the correctamount?arrow_forwardIf a red blood cell was placed in a 50mOSM solution, the cell would:arrow_forwardMany old time folk remedies made use of the priciples of diffusion and osmosis. Suppose you had a sliver of wood or another small foreign object embedded under your skin. It is slightly swollen and hurts. Your grandma or older neighbor tells you to soak the affected part in salt water. Using your knowledge of diffusion/osmosis, how do you think this would affect the injury? Will it help you get the sliver out?arrow_forward
