Textbook Question
Chapter 41, Problem 4RQ
When a dehydrated human patient needs to be given fluids intravenously, he or she is given:
- water, which is hypotonic with respect to body fluids
- saline at a concentration that is isotonic with respect to body fluids
- glucose because it is a non-electrolyte
- blood

When a dehydrated human patient needs to be given fluids intravenously, he or she is given: a. water, which is hypotonic with respect to body fluids b. saline at a concentration that is isotonic with respect to body fluids c. glucose because it is a non-electrolyte d. blood
A drug is infused intravenously (IV) for treatment of a particular disease. The infusion rate of the drug is k0 = 200 mg/hr. The volume of the body fluid V = 16 liters. The drug is excreted (removed) through the kidneys at rate ke = 0.3/hr, proportional to the concentration of the drug in the body fluids. How much is the maximum concentration of the drug in the body in the steady state in mg/l?
Which of the following best describes blood plasma?
Group of answer choices
found inbetween the cells, not in them, so called intracellular
found in vessels, not cells, so it is a type of extracellular fluid
found between vessels, not in them, so thought of as extracellular
found within the cells, not outside, so normally called interstitial
The sodium-potassium pump balances intracellular and extracellular ions by:
Group of answer choices
the use of ionic pressure
active transport of ions
creating osmotic pressure
employing hydrostatic pressure
What force drives fluid into lymphatic capillaries?
Group of answer choices
colloidal osmotic pressure
hydrostatic pressure
active transport of fluids
diffusion of water
