## Question

A client taking warfarin is preparing for discharge. Which statements show correct understanding? Select exactly 3 responses.

Select exactly 3 responses.

1

I will double tomorrow's dose if I forget to take today's dose of warfarin.

2

I can take ibuprofen for aches because it does not increase bleeding while I take warfarin.

3

I will keep my INR appointments and take warfarin at the same time each day.

4

I will call the provider before starting any prescription, over-the-counter, vitamin, or herbal product.

5

I will seek prompt advice after a fall or head injury, or if I notice black stool or pink urine.

6

I will stop warfarin before dental cleaning without first contacting the prescriber.

## Explanation

Correct selections are 1, 2, and 4. Warfarin requires regular INR monitoring and consistent dosing. Prescription drugs, over-the-counter drugs, vitamins, and herbal products can alter anticoagulation and should be reviewed before use. A fall or head injury and signs of bleeding such as black stool or pink urine require prompt advice. The client should not double a missed dose, self-stop warfarin, or use ibuprofen without clinician guidance.

## In-depth explanation

Clinical reasoning
Warfarin has a narrow therapeutic range and many drug interactions. Bleeding can be occult, and head trauma can cause dangerous bleeding even before symptoms are obvious.

Decision rule
Take warfarin consistently, keep INR checks, review every new medicine or supplement, and report trauma or bleeding promptly. Never double or stop doses independently.
