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)]

A. Instruct the client that since the hematocrit remains low, the daily injections are still necessary: A hematocrit of 43% is within the normal range, suggesting the client’s anemia is improving. If the hematocrit were still low, continuing daily injections would be appropriate, but this is not the case here. B. Notify the healthcare provider of the client’s hematocrit level so the frequency of injections can be reduced: Since the hematocrit is normal, there is no need to notify the healthcare provider specifically for changing the injection frequency based solely on the hematocrit level. Reducing injection frequency should be based on the overall treatment plan and not just the current hematocrit. C. 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: While the medication may be effective, informing the client about the potential for less frequent injections could improve adherence and reduce discomfort, if the healthcare provider approves. D. Offer to instruct the client in self-administration techniques to improve the client's sense of control over the painful daily injections: Teaching self-administration can empower the client and potentially reduce discomfort by allowing the client to become more comfortable with the process. It also offers the opportunity for the client to manage their injections more conveniently and with greater control.
