The nurse is caring for a client with atrial fibrillation who receives a prescription for warfarin. The international normalized ratio (INR) is 2.8. Which action should the nurse take?

 

Choice A reason: Giving the next scheduled dose without further assessment is not advisable. An INR of 2.8 is within the therapeutic range for many conditions treated with warfarin, but it is important to ensure that the INR is stable and not trending higher, which could increase the risk of bleeding.

Choice B reason: Obtaining another blood sample might be necessary if there is suspicion of an error or if the INR is unexpectedly high or low. However, in this scenario, the INR is within the therapeutic range, so this action is not immediately necessary.

Choice C reason: Monitoring for signs of bleeding is always important for clients on warfarin, but it does not address the immediate need to communicate with the healthcare provider about the current INR level and any potential adjustments to the medication.

Choice D reason: Notifying the healthcare provider is the most appropriate action. The healthcare provider needs to be aware of the current INR level to make any necessary adjustments to the warfarin dosage and to provide further instructions on monitoring and follow-up.

Choice A reason:

Resuming a diet that consists of milk, cream, and bland foods is not the most critical instruction for a client taking esomeprazole. While bland foods can help reduce gastric irritation, they do not address the primary concern of monitoring for serious side effects. Esomeprazole is a proton pump inhibitor (PPI) that reduces stomach acid, and dietary changes alone are not sufficient to manage potential complications.

Choice B reason:

Calling the clinic if diarrhea or headache occurs when taking esomeprazole is important, but it is not the most critical instruction. Diarrhea and headache are common side effects of esomeprazole, but they are usually not severe. The client should be aware of these potential side effects, but the primary concern is monitoring for signs of gastrointestinal bleeding.

Choice C reason:

Once pain subsides, NSAID therapy should not be resumed without consulting the healthcare provider. NSAIDs can cause significant gastrointestinal issues, including ulcers and bleeding. The client should be advised to avoid NSAIDs unless specifically directed by their healthcare provider.

Choice D reason:

Notifying the healthcare provider of the passage of black stools is the most critical instruction. Black stools can indicate gastrointestinal bleeding, which is a serious side effect of both NSAIDs and esomeprazole. Immediate medical attention is necessary if this occurs to prevent further complications.
