A nurse is transcribing a new prescription for a client which states, "Diphenhydramine 50 mg NOW." Which of the following actions should the nurse take?

Choice A Reason:
The medication vial sat at room temperature for 2 hr before it was administered is correct. Medications like filgrastim typically have specific storage requirements, including temperature control. Allowing the medication vial to sit at room temperature for an extended period may compromise its stability or effectiveness, leading to potential concerns regarding medication safety. Reporting incidents related to improper medication storage is essential to ensure patient safety and prevent similar occurrences in the future.
Choice B Reason:
The client's absolute neutrophil count was 2,500/mm3 before the medication was administered. Is incorrect. A normal or adequate absolute neutrophil count (ANC) of 2,500/mm3 before administering filgrastim is not an adverse event that requires an incident report.
Choice C Reason:
The nurse flushed the client's IV line with dextrose 5% in water before and after the medication was administered. Is incorrect. Flushing the IV line with dextrose 5% in water is a standard practice and not considered an adverse event or reason for filing an incident report.
Choice D Reason:
The client had chemotherapy 12 hr before the medication was administered. Is incorrect. The timing of previous chemotherapy administration, in this case, doesn't inherently suggest an adverse event requiring an incident report.

Choice A Reason:
Giving the prescribed dose of clindamycin is not appropriate due to the reported penicillin allergy, which increases the risk of an allergic reaction.
Choice B Reason:
Obtain a prescription for an alternative antibiotic is correct. Given the client's reported allergy to penicillin, which is in the same antibiotic class as clindamycin (both are antibiotics that belong to the beta-lactam group), there is a higher risk of cross-reactivity and potential allergic reaction. Therefore, it's important to avoid administering clindamycin in such cases and seek an alternative antibiotic that does not have a similar chemical structure to penicillin to prevent an allergic reaction.
Choice C Reason:
Premeditating the client with epinephrine before administering the antibiotic is not a standard practice in this context. Epinephrine is used to treat severe allergic reactions but is not used as a preventive measure before administering antibiotics.
Choice D Reason:
Administering the clindamycin using a desensitization schedule might be an option in certain situations under the guidance of an allergist or immunologist, but it's not typically performed by nurses and requires a specific protocol and expertise in managing drug allergies. Obtaining an alternative antibiotic is a more appropriate and immediate action to avoid the risk of an allergic reaction in this scenario.
