An older adult client with pernicious anemia has been receiving daily injections of cyanocobalamin for two weeks and reports that the injections are painful. The nurse notes that the client's hematocrit is 43% (0.43 volume fraction). Which action should the nurse implement? Reference Range: Hematocrit (Hct) [37% to 47% (0.37 to 0.47 volume fraction)]

Instruct the client that since the hematocrit remains low, the daily injections are still necessary.

Notify the healthcare provider of the patient's hematocrit level so the frequency of injections can be reduced.

Advise the client that the medication is having the desired effect, but daily injections will continue to be needed for life for this chronic condition.

Offer to instruct the client in self-administration techniques to improve the client's sense of control over the painful daily injections.
