A nurse is teaching a client who has multiple sclerosis. Which of the following instructions should the nurse include in the teaching?

Rationale:

A. Consult the pharmacist about potential interactions between the client's regular medications and warfarin: Warfarin has numerous drug interactions that can increase bleeding risk or reduce effectiveness. Consulting the pharmacist ensures a thorough review of the client’s medication list for potential harmful interactions before discharge.

B. Tell the client they can continue to drink cranberry juice while taking warfarin: Cranberry juice can potentiate the effects of warfarin and increase bleeding risk by interfering with its metabolism. Clients should be advised to limit or avoid cranberry products.

C. Recommend the client take warfarin at the same time as other medications: Warfarin should be taken at the same time each day, but taking it with other medications may cause interactions. The timing should consider spacing it from medications that might interfere with absorption or potency.

D. Advise the client that over-the-counter medications remain safe to consume as needed: Many OTC medications, especially NSAIDs, can increase bleeding risk when combined with warfarin. Clients need to check with a healthcare provider before taking any new OTC drugs.

Rationale:

A. A client who has an open compound fracture of the humerus: This injury requires surgical intervention and has a moderate to high risk of complications. It is typically classified as yellow, indicating delayed care is acceptable but not minor.

B. A client who has multiple facial lacerations: These are superficial injuries that can be treated with simple wound care and suturing. The client is likely stable and ambulatory, fitting the criteria for a green tag, which denotes minor injuries requiring minimal care.

C. A client who has a puncture wound in the right lower lung: This suggests potential internal injury and respiratory compromise. Such a case is urgent and unstable, requiring immediate intervention, and would be tagged red for immediate treatment.

D. A client who has full-thickness burns over the lower extremities: Full-thickness burns covering a large area are life-threatening and resource-intensive to manage. Depending on the extent, this may fall under red or black, depending on survivability and available resources.
