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.

- drugs known as potassium-sparing diuretics work by blocking the effects of aldosterone on the kidney. what effect would these drugs have on the amount of urine produced, on the blood pressure, and on potassium ion concentration in the blood? could these drugs have a negative impact on the acid-base balance of the body? explain.arrow_forwardHyperkalemia is associated with the inability of the kidneys to properly filter potassium out of the blood. Which type of membrane transport do the kidneys use to filter the blood? A. Hydrostatic pressure B. Osmotic pressure C. Filtration D. Active diffusionarrow_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_forward
- In the management of DKA, why would potassium be added to the maintenance fluids even if potassium levels are normal or high? Question 66 options: a) Potassium shifts from the extracellular fluid to the intracellular fluid when acidosis corrects b) Insulin promotes renal potassium loss c) Osmotic diuresis may continue to deplete extracellular fluid potassium levels d) Maintenance fluids will dilute potassium levels in the extracellular fluidarrow_forwardThe renal handling of a novel drug is being studied. When the drug is present in the blood, it is filtered into the Bowman’s capsule and secreted via transport proteins in the renal tubules, but it is NOT reabsorbed. The lines on the following graph represent filtration, secretion and excretion rates of this drug at various plasma concentrations. For the three lines shown (labeled A-C) identify which line represents filtration, which line represents secretion, and which line represents excretion Explain how you determined this.arrow_forwardWhy would it be dangerous to administer intravenous fluids that do not have an osmotic pressure comparable to that of bodily fluids?arrow_forward
- Sodium and chloride are the predominant electrolytes in the extracellular fluid. A. True B. Falsearrow_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_forwardTwo solutions are separated by a semipermeable membrane that is permeable only to water. The two solutions are: Solution A = 150 mM KCl Solution B = 150 mM Angiotensin (a 7 amino acid polypeptide) Which of the following would best explain the net movement in this situation? - water will move from the KCl side to Angiotensin side - water will move from Angiotensin side to KCl side - The Cl- ion will move to the angiotensin side until there is 75 mM Cl- on each side - Since Angiotensin is not an ion, it can move through the membrane - There is no net water movement as the concentrations are the same on both sidesarrow_forward
- Describe the following fluid compartments in the body Intracellular (ICF) Extracellular (ECF) Plasma Interstitialarrow_forwardWhich of the following is TRUE about glucose reabsorption in the kidney? a.If an individual does not have diabetes mellitus, 100% of filtered glucose is reabsorbed at the proximal convoluted tubule. b.If an individual has diabetes mellitus, filtered glucose will be present in all the renal tubule. c.Glucose reabsorption along the proximal convoluted tubule uses the sodium glucose secondary active transporter and it is independent of insulin. d.All of the above e.None of the above asaparrow_forwardexcess sodium ion is considered hazardous, but a certain amount is necessary for normal body functions. What is the purpose of sodium in the body?arrow_forward
