A nurse is reviewing the laboratory results of a client who has atrial fibrillation and a prescription for warfarin. After informing the provider that the INR is 2.5, the nurse should expect which of the following prescriptions?

Choice A Reason:
INR (International Normalized Ratio) is incorrect. INR is a measurement used to monitor the effects of anticoagulants like warfarin. It assesses the blood's ability to clot. Filgrastim does not directly affect INR levels, so monitoring INR would not provide information about the effectiveness of filgrastim in stimulating white blood cell production.
Choice B Reason:
BUN (Blood Urea Nitrogen) is incorrect. BUN levels primarily indicate kidney function and hydration status. They are not directly influenced by filgrastim treatment. Monitoring BUN is essential for assessing kidney function but does not reflect the effectiveness of filgrastim therapy in increasing white blood cell counts.
Choice C Reason:
WBC count is correct. Filgrastim is a medication that stimulates the production of white blood cells (WBCs), particularly neutrophils. Therefore, the key laboratory value to monitor for assessing the effectiveness of filgrastim therapy is the WBC count. An increase in the WBC count, particularly in the neutrophil count, signifies the intended therapeutic effect of filgrastim in boosting the immune system's response by increasing the production of these infection-fighting cells.
Choice D Reason:
Potassium level is incorrect. Potassium levels are crucial for heart and muscle function. While certain medications might affect potassium levels, filgrastim's primary action is on stimulating white blood cell production and does not directly impact potassium levels. Monitoring potassium levels is essential for overall health but does not specifically indicate the effectiveness of filgrastim treatment.

Choice A Reason:
Identify the client using two identifiers is correct. Prior to administering any medication, especially controlled substances, it's crucial to confirm the client's identity using two unique identifiers, such as their name and date of birth or an identification band and verbal confirmation. Ensuring accurate identification helps prevent medication errors and ensures the right medication is given to the right patient.
Choice B Reason:
Compare the amount of medication available to the inventory record is incorrect. This is part of maintaining accurate documentation and inventory control, ensuring that the amount of medication matches the recorded inventory. However, it typically occurs after confirming the client's identity.
Choice C Reason:
Document the administration of the medication is incorrect. Documentation of medication administration is crucial for legal and medical purposes but should occur after the medication has been safely administered to the correct patient.
Choice D Reason:
Remove the medication from the medication dispensing cabinet is incorrect. Retrieving the medication from the dispensing cabinet is an essential step in the administration process, but it should occur after confirming the client's identity to ensure the right medication is administered to the right individual.
