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?

Obtain another blood sample.

Give the next scheduled dose.

Monitor for signs of bleeding.

Notify the healthcare provider.

Answer and Explanation

The Correct Answer is C

A. An INR of 2.8 is within the therapeutic range for clients on warfarin, so obtaining another blood sample is not necessary.
B. An INR of 2.8 indicates that the client is within the therapeutic range, so it is appropriate to give the next scheduled dose. However, monitoring for potential bleeding complications is a higher priority.
C. Monitoring for signs of bleeding is crucial because, while an INR of 2.8 is within the therapeutic range, it is still important to watch for any bleeding complications as part of routine care.
D. Notifying the healthcare provider is not immediately necessary unless there are signs of bleeding or other concerns, as an INR of 2.8 is typically within the acceptable range for therapeutic anticoagulation.

Correct Answer is B

C. The time of day the medication is taken is less critical compared to managing side effects related to blood pressure changes.
D. Tamsulosin is typically taken once daily, not on a twice-a-week schedule.

A. Increased frequency of lacrimation. B. Decreased night vision. C. Increased sensitivity to light. D. Diminished color perception.

Correct Answer is B

Explanation

A. Increased lacrimation may cause discomfort but does not directly contribute to a risk of injury.
B. Miotics constrict the pupil, leading to decreased night vision, which increases the client's risk for injury, particularly in low-light conditions.
C. Sensitivity to light (photophobia) may cause discomfort but is less likely to contribute directly to injury.
D. Diminished color perception can occur but does not typically pose a significant risk for injury compared to decreased night vision.
