  b. give an initial dose of 0.5 mg digoxin tablet and then 0.125 mg every 6 hours 4.
  c. administer a digoxin 0.6 mg capsule once and then 0.3 mg every 8 hours 3.
  d. administer a loading dose of intravenous digoxin in the clinic and then give 0.125 mg once daily.

  c. write the alternative drug regimen on the prescription and send it to the pharmacy.

Answer to Question 1

A
In primary care settings, slow digitalization rather than a loading dose is generally recommended because of the risk of toxicity. Digitalization may be achieved within 1 week with the use of small daily maintenance doses.

Answer to Question 2

A
When prescribing a drug for an off-label use, the provider should specify this on the written prescription and should provide a rationale so that the pharmacist understands why the prescription is different from the normal use. Calling the pharmacist would not provide written documentation. Merely writing the different instructions can lead to errors if the pharmacist changes the label to conform to usual standards. The patient may forget verbal instructions and follow the usual regimen instead.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
