Concept explainers
a.
To determine: The intracellular and interstitial fluid volume of a patient if the total body water volume is 42 L, ECF volume is found to be 12.5 L, and the plasma volume of the patient is 2.7 L.
Introduction: In humans, body fluid is present in different compartments forms. Body fluid in each compartment has its characteristics and functions to perform. These compartments in the body are separated by some form of physical barriers. Fluid in each of these compartments increases or decreases according to the physiological conditions of the body. Two of the main fluid compartments in the body are: Intracellular fluid (ICF) compartment; and Extracellular fluid (ECF) compartment.
b.
To determine: The amount of solute present in the whole body, ECF, ICF, and plasma of the patient.
Introduction: Different body fluids contain different amount of solute particles. Based on the concentration of solute present in the fluid, a concentration gradient is set up between the fluids. This concentration gradient is responsible for the movement of water across the boundaries. The concentration of these solutes is measured in terms of the osmolarity of the fluid.

- Steven is a 35 year old male. To gain a better understanding of fluid requirement, you have decided to calculate his hourly sweat rate. You have collected the following data: · Exercise duration: 2 hours· Pre-exercise body mass: 85kg· Post-exercise body mass: 82.5kg· Fluid consumed during exercise: 350mL· Urine loss during exercise: 50mL From this data, what is his hourly sweat rate? Based on this, how much fluid should he consume during training?arrow_forwardA drug is infused intravenously (IV) for treatment of a particular disease. The infusion rate of the drug is ko = 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?arrow_forwardA drug is infused intravenously (IV) for treatment of a particular disease.

- A patient receives an intravenous (IV) solution that flows at the rate of 150 mL per hour. How much fluid does the patient receive in 20. min? (Answer = 50 mL) How long does it take for the patient to receive 90. mL of fluid? (Ans. = 0.6 hr or 36 min.) If the IV bag holds 600. mL of fluid, how many minutes does it take to empty the bag? (t = 4 hrs) If the solution contains 90. mg of glucose per mL, how long will it take to give the patient 2.0 g of glucose? (t = 0.15 hr or 9 min)arrow_forwardPatient with dehydration was started on fluid therapy. If 5% dextrose is isoosmotic to plasma what effect would infusion of 1L of a 10% dextrose solution have on ECF and ICF volumes? How it would affect body fluid osmolality of a 70 kg individual and why?arrow_forwardA 60-year-old woman with history of lung cancer is admitted for weakness and lethargy for 4 weeks. Her serum [Na*] is 120 mEq/L. She weighs 60 kg. Her serum osmolality is 250 mOsm/kg H2O with urine osmolality of 616 mOsm/kg H2O. The diagnosis of SIADH is made. What would be her serum [Na], if she receives 1 L of isotonic saline? A. 122 mEq/L B. 116 mEq/L C. 118 mEq/L D. 120 mEq/L E. 124 mEq/Larrow_forward
- the major difference between plasma and interstitial fluid is the absence of plasma proteins from the interstitial. explain how this affects solute distrbution and what kind of correction you would do it if you were measuring solute concentrationarrow_forwarda. A person ingests an ion-channel inhibitor, such that the ion channels present in the Loop of Henle are only able to pump at half their normal rate? b. What would this person notice about changes to their physiological filtration? (Answer a and b)arrow_forwardA 26-year-old woman reports that she has a severe migraine and has taken six times more than the recommended dose of aspirin for the past 3 days to relieve her headaches. Her plasma pH is 7.24. Which of the following would you expect to find compared with normal? Group of answer choices Increased NH4+ excretion Decreased NH4+ excretion No change in NH4+ excretion none of the abovearrow_forward

Select one: a. Drinking 1 L of water in a short period of time. (Assume that you weren't dehydrated.) b. Eating a big bag of salty potato chips. c. Forgetting to drink water all day. d. Exercising vigorously in a very hot environment. e. All of the abovearrow_forwardBlood plasma has an osmolarity of about Group of answer choices: 100 mOsm/L. 900 mOsm/L. 1200 mOsm/L. 300 mOsm/L. 30 mOsm/L.arrow_forward
