the question is
When a nurse is preparing a scheduled dose of digoxin for an adult patient, the lab results indicate that the plasma level of digoxin is 1.5 ng/mL. Should the nurse:
a. withhold the drug and notify the health care provider immediatley.
b. withhold the drug and notify the health care provider during rounds.
c. administer Digibind to counteract the toxicity.
d. check the client's pulse and if it is greater than 60 beats per minute,
administer the dose of digoxin.
In my source on digoxin, it states that therapeutic serum levels are 0.5 to 2.0 nanograms/milliliter. In the elderly the therapeutic serum level is between 0.5 and 1.3 ng/mL.
But later in the source, there is a research summary in which the authors state that their findings suggest that serum levels, for men and women, must be kept as low as possible (0.5 to 1 ng/m).
The source is a course textbook for pharmacology.
Is the therapeutic range 0.5 to 1 ng/mL or 0.5 to 2 ng/mL?
I was going to select d, but after reading the research summary, then I wondered if a is correct?
