Final answer:
The nurse would likely notify the health care provider of the patient's high digoxin and potassium levels and anticipate the prescription of Digoxin immune Fab to treat digoxin toxicity.
Step-by-step explanation:
The question involves a patient with a digoxin level of 11 ng/mL and a serum potassium level of 6.2 mEq/L. Both of these values are concerning. A digoxin level of 11 ng/mL is significantly higher than the therapeutic range of 0.5-2 ng/mL, indicating digoxin toxicity.
Additionally, a serum potassium level of 6.2 mEq/L is above the normal range (3.5-5.0 mEq/L), suggesting hyperkalemia.
The appropriate medication to treat digoxin toxicity is Digoxin Immune Fab (option B), which is an antidote that can bind to and neutralize digoxin, thereby reducing its effects. In the case of hyperkalemia, medications like insulin combined with glucose, or others may be used to lower potassium levels, but they are not among the options provided. Sodium polystyrene sulfonate (Kayexalate) (option C) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the gastrointestinal tract, but in this question, the immediate concern is addressing the high digoxin level.
The nurse would notify the health care provider about the abnormal lab values and anticipate that Digoxin immune Fab would be the medication prescribed to administer.
