A nurse is consulting a pharmacological reference about medication compatibility prior to administering warfarin to a client.
Which of the following medications should the nurse identify as being incompatible with warfarin?

Choice A rationale:

An altered level of consciousness is a common finding in clients with Alzheimer's disease. This may range from mild confusion to severe cognitive impairment. It is caused by the degeneration of brain cells and affects memory, thinking, and behavior.

Choice B rationale:

Rapid mood swings are not specific to Alzheimer's disease. While mood changes can occur, they are not typically characterized by rapid swings. Mood disturbances may include depression, apathy, or irritability, but these symptoms are not unique to Alzheimer's disease.

Choice C rationale:

Excessive motor activity is not a typical finding in clients with Alzheimer's disease. Instead, clients often experience a decline in motor skills and coordination as the disease progresses. Restlessness or agitation might occur, but excessive motor activity is not a characteristic feature.

Choice D rationale:

Failure to recognize familiar objects, people, or places is a common symptom of Alzheimer's disease. This is due to the damage and loss of nerve cells in the brain. As the disease advances, clients may have difficulty recognizing even close family members or their own reflection in the mirror.

Choice A rationale:

(Correct Choice) Checking the expiration date on the safety inspection sticker of the pump is essential to ensure the equipment is functioning properly and safely. Using expired equipment can compromise the client's safety and the effectiveness of the treatment.

Choice B rationale:

Verifying that the extension cord for the pump is ungrounded is important for electrical safety. However, it is not the nurse's responsibility to do this. This action should be performed by a qualified electrician or facility maintenance personnel.

Choice C rationale:

Reporting the pump with a frayed cord is essential. However, it is not safe to proceed with the infusion in this situation. Using damaged equipment can lead to electrical hazards and compromise the client's safety.

Choice D rationale:

Obtaining a surge protector is important for protecting the pump and other electrical appliances from power surges. While this is a good practice, it is not the first action the nurse should take when preparing to initiate intravenous fluids.
