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?
Decrease the dose of the medication.
Increase the dose of the medication.
Withhold the medication.
Administer the current dose of the medication.
The Correct Answer is D
Choice A Reason:
Decrease the dose of the medication is incorrect. Lowering the dose could potentially drop the INR below the therapeutic range, increasing the risk of clot formation.
Choice B Reason:
Increase the dose of the medication is incorrect. Raising the dose might push the INR above the therapeutic range, increasing the risk of bleeding.
Choice C Reason:
Withhold the medication is incorrect. Withholding the medication might lead to inadequate anticoagulation and an increased risk of clot formation.
Choice D Reason:
Administer the current dose of the medication. An INR of 2.5 is within the therapeutic range for many indications, including atrial fibrillation. This means the blood is appropriately anticoagulated to prevent clot formation without an excessive risk of bleeding. In this scenario, maintaining the current dose of warfarin is often appropriate to sustain the desired therapeutic effect.

Correct Answer is C
Explanation
Choice A Reason:
Determine factors that led to the omission. Understanding why the dosage was missed is crucial. Was there a specific reason such as an interruption, conflicting priorities, or confusion in the medication schedule? Identifying these factors can help prevent future omissions and improve the medication administration process.
Choice B Reason:
File an incident report. If the missed dosage poses any potential risk or deviation from the prescribed treatment plan, it's important to document the incident through an incident report. This ensures transparency and allows the healthcare team to address and learn from the situation.
Choice C Reason:
Report the missed dosage to the client's provider. Informing the client's healthcare provider about the missed dosage is crucial. The provider can assess the situation and provide guidance on whether any adjustments or additional steps are necessary to ensure the client's well-being.
Choice D Reason:
Assess the client for adverse reactions. Monitoring the client for any adverse reactions or changes in their condition is essential after a missed dosage. This observation helps detect any potential effects of the missed medication and allows for prompt intervention if needed.
Correct Answer is A
Explanation
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.
