Fluid/Electrolytes & Acid Base Final
Exam Questions Correctly Answered.
Define solute - CORRECT ANSWER A solute is a solid substance dissolved in body fluids.
Define intracellular fluid - CORRECT ANSWER (ICF) fluid contained within the cells
Define extracellular fluid - CORRECT ANSWER (ECF) fluid outside the cells. ECF consists of three types of
fluid: interstitial, intravascular, and transcellular fluid.
Define electrolyte - CORRECT ANSWER An electrolyte is a substance that develops an electrical charge
when dissolved in water.
Define cation - CORRECT ANSWER an electrolyte that carries a positive charge. They include sodium
(Na+), potassium (K+), calcium (Ca2+), and magnesium (Mg2+).
Define anion - CORRECT ANSWER An anion is an electrolyte that carries a negative charge. Examples are
chloride (Cl−), bicarbonate (HCO3−), phosphate (HPO42−), and sulfate (SO42−).
Identify the major electrolytes in the ICF - CORRECT ANSWER In intracellular fluid (ICF), the major cations
are potassium (K+) and magnesium (Mg2+), and the major anion is phosphate (HPO42−)
identify major electrolytes in ECF - CORRECT ANSWER In extracellular fluid (ECF), the major cation is
sodium (Na+), and the major anions are chloride (Cl−) and bicarbonate (HCO3−).
Molecules move across a membrane to equalize concentration. - CORRECT ANSWER Diffusion
Fluid moves across a membrane to equalize concentration. - CORRECT ANSWER Osmosis
Molecules move against a concentration gradient. - CORRECT ANSWER Active transport
, Molecules move to equalize pressure. - CORRECT ANSWER Filtration
Identify the major functions of sodium - CORRECT ANSWER (Sodium)
- Regulates fluid volume
- Helps maintain blood volume
- Interacts with calcium to maintain muscle contraction
-Stimulates conduction of nerve impulses
Identify the major functions of calcium - CORRECT ANSWER (Calcium)
- Promotes transmission of nerve impulses
- Regulates muscle contractions
- Maintains cardiac automaticity
- Serves as an essential factor in the formation of blood clots
- Catalyzes many cellular activities
- The major component of bones and teeth
Identify the major functions of potassium - CORRECT ANSWER (Potassium)
- Maintains osmolality of intracellular fluid
- Regulates conduction of cardiac rhythm
- Transmits electrical impulses in multiple body systems
-Assists with acid-base balance
identify the major functions of Magnesium - CORRECT ANSWER (Magnesium)
- Involved in protein and carbohydrate metabolism
- Necessary for protein and DNA synthesis within the cell
- Maintains normal intracellular levels of potassium
- Involved in electrical activity in nerve, cardiac, and muscle membranes
