Learning goal: to understand the relation between the strength of an acid or a base and its pka and pkb values. the degree to which a weak acid dissociates in solution is given by its acid-ionization constant, ka. for the generic weak acid, ha, ha(aq)⇌a−(aq)+h+(aq) and the acid-ionization constant is given by ka=[a−][h+][ha] similarly, the degree to which a weak base reacts with h2o in solution is given by its base-ionization constant, kb. for the generic weak base, b, b(aq)+h2o(l)⇌bh+(aq)+oh−(aq) and the base-ionization constant is given by kb=[bh+][oh−][b]

If a reactant was removed, did the new equilibrium system shift to make more reactants or more products?

For a patient with the following pes statement and interventions, which would be the most appropriate monitoring and evaluating data? pes statement: inadequate calcium intake related to food and nutrition related knowledge deficit as evidenced by statements that the only dietary source of calcium is milk and she believes that she is lactose intolerant. patient’s nutrition prescription is for a diet providing 1200 mg calcium per day. patient was provided with in-depth nutrition education on alternative dietary and supplement sources of calcium. a. calcium intake (at subsequent visit) b. knowledge assessment by asking patient to identify food sources from menus and shopping list (at the end of the current visit) c. serum calcium (at next visit) d. both a and b e. both a and c
