NURSING 2 WEEK 2 FLUID AND ELECTROLYTE ONLINE QUIZ. Question 1 of 20 5.0 Points The movement of fluid across the arterial end of capillary membranes into the intersti- tial fluid surrounding the capillary is an example of which process of fluid movement A. Hydrostatic pressure B. Osmosis C. Diffusion D. Active transport 5.0 Points How is passive transport described? A. It is driven by osmosis, filtration, and diffusion. B. It involves receptors that can bind with substances being transported. C. It is capable of transporting macromolecules. D. It requires energy generated by the cell. Question 3 of 20 5.0 Points The fluid percent of total body weight is highest in the newborn ( 1 year old) and low- est in older adults ( 60 years old) A.True Question 4 of 20 5.0 Points In a hypotonic solution A. the water concentration is greater inside the cell and the solute concentration is greater outside the cell causing water to leave the cell. B. the water concentration is greater outside the cell and the solute concentration is greater inside cell causing water to be drawn into the cell. C. the water concentration is equal on both sides of the cell membrane, but the solute concentration is greater outside of the cell causing water to leave the cell. D. the water concentration is greater inside the cell, but the solute concentration is equal on both sides of the cell causing water to be drawn into the cell. Question 5 of 20 5.0 Points Differences in cardiac dysrthymias between hyperkalemia and hypokalemia include: A. In hyperkalemia there is an increased heart rate and flat- tened T wave whereas in hypokalemia there is a decreased heart rate and elevated T wave B. In hyperkalemia there is muscle rigidity and a bounding pulse whereas in hypokalemia there is muscle weakness and diminished pulse C. In hyperkalemia there is a slowed heart rate and muscle weakness whereas in hypokalemia there is an elevation in blood pressure and diminished deep tendon reflexes D. There are no cardiac dysrhymias with hyperkalemia or hy- pokalemia Question 6 of 20 5.0 Points The pathophysiologic process of edema is related to which mechanism A. Sodium depletion B. Decreased capillary hydrostatic pressure C. Increased plasma oncotic pressure D. Lymphatic obstruction Question 7 of 20 5.0 Points Insulin is used to treat hyperkalemia because it: A. Stimulates sodium to be removed from the cell in exchange for potassium. B. Binds to potassium to remove it through the kidneys. C. Transports potassium from the blood to the cell along with glucose. D. Breaks down the chemical components of potassium, caus- ing it to be no longer effective Question 8 of 20 5.0 Points A major determinant of the resting membrane potential necessary for the transmission of nerve impulses is the ratio between: A.

Hypophosphatemia Question 11 of 20 5.0 Points Extracellular fluids in the body consist of: A. Cerebrospinal fluid, synovial fluid, and serous fluids B. Aqueous humor, perilymph and endolymph C. interstitial fluid, blood plasma, and lymph D. All of the above Question 12 of 20 5.0 Points When water is lost but electrolytes are retained, the osmolarity of the ECF rises and osmosis then moves water: C. Out of the ICF and into the ECF until isotonicity is reached D. Back and forth between the ICF and the ECF Question 13 of 20 5.0 Points Physiological adjustments affecting fluid and electrolyte balance are mediated primar- ily by: A. Aldosterone B. Atrial natriuretic peptide (ANP) C. Antidiuretic hormone (ADH) Question 14 of 20 5.0 Points The major contributors to the osmolarities of the ECF and the ICF are: A. Renin and angiotensin B.
