A patient who has atrial fibrillation is taking warfarin and has an INR of 2.5.The patient reports having frequent headaches and asks for an over-the-counter pain reliever.The nurse will recommend which medication?

Ibuprofen

Naproxen

Acetaminophen

Aspirin.

Answer and Explanation

The Correct Answer is C

The patient reports having frequent headaches and asks for an over-the-counter pain reliever. The nurse will recommend acetaminophen, which is the safest pain reliever while taking warfarin. Acetaminophen does not interfere with the anticoagulant effect of warfarin and does not increase the risk of bleeding.

Choice A is wrong because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can enhance the anticoagulant effect of warfarin and increase the likelihood of harmful bleeding.

NSAIDs can also cause stomach ulcers, kidney damage, and high blood pressure.

Choice B is wrong because naproxen is another NSAID that has the same risks as ibuprofen.

Naproxen should be avoided by patients taking warfarin.

Choice D is wrong because aspirin is also an anticoagulant that can increase the risk of bleeding when taken with warfarin.

Aspirin can also cause stomach irritation, ulcers, and allergic reactions.

The normal range for INR is 2 to 3 for patients with atrial fibrillation who are taking warfarin.

An INR of 2.5 indicates that the patient’s blood is taking longer to clot than normal, but not too long.

The patient should have regular blood tests to monitor their INR and adjust their warfarin dose if needed.

Correct Answer is B

Explanation

This statement indicates that the patient understands that rivaroxaban (Xarelto) is an anticoagulant that can increase the risk of bleeding and bruising.The patient should avoid activities that may cause injury, such as contact sports, sharp objects, or falls.

Choice A is wrong because aspirin is also an antiplatelet drug that can further increase the risk of bleeding when taken with rivaroxaban.The patient should not take aspirin or any other nonsteroidal anti-inflammatory drugs (NSAIDs) without consulting the prescriber.

Choice C is wrong because rivaroxaban can be taken with or without food.The patient does not need to take the medication with food to prevent stomach upset or absorption problems.

Choice D is wrong because rivaroxaban should be taken as prescribed and not stopped abruptly without consulting the prescriber.Stopping the medication can increase the risk of blood clots and stroke.The patient should not stop taking the medication even if they feel better or have no symptoms.

A. History of hypertension B. History of stroke C. History of peptic ulcer disease D. History of diabetes mellitus. E. Shortness of breath.

Correct Answer is B

Explanation

A history of stroke is an absolute contraindication to the administration of a thrombolytic to a patient having an acute myocardial infarction (AMI).This is because thrombolytics can increase the risk of intracranial hemorrhage and worsen the neurological outcome.

Choice A is wrong because history of hypertension is not an absolute contraindication, but a relative one.This means that the benefits of thrombolytic therapy may outweigh the risks in some cases, depending on the severity and duration of hypertension.

Choice C is wrong because history of peptic ulcer disease is also a relative contraindication, not an absolute one.Thrombolytics can increase the risk of gastrointestinal bleeding, but this can be managed with proton pump inhibitors or histamine-2 blockers.

Choice D is wrong because history of diabetes mellitus is not a contraindication at all to thrombolytic therapy.In fact, some studies have shown that diabetic patients with AMI may benefit more from thrombolytic therapy than non-diabetic patients.
