A nurse is preparing to administer erythromycin 2 g PO daily in equally divided doses every 6 hr. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. “Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose": This statement is not necessary for the administration of nasal cyanocobalamin. Nasal decongestants are not routinely recommended before administering nasal medications.
B. "Plan to self-administer this medication for the next 6 months": While the duration of treatment for pernicious anemia may vary, specifying a timeframe of 6 months for self- administration is not appropriate without considering individualized treatment plans.

method provides a convenient and effective route for vitamin B12 supplementation in clients with pernicious anemia.
