What symptom should alert a home health nurse to a potential adverse effect of tacrine hydrochloride?

The symptom that should alert a home health nurse to a potential adverse effect of tacrine hydrochloride is a change in the color of the skin or stool. Tacrine is a medication used primarily to treat symptoms of Alzheimer's disease, and it can affect liver function. One of the signs of hepatic toxicity is jaundice, which manifests as a change in skin color (yellowing) and can also affect the color of stool. Darkening of urine and light-colored stools may indicate that the liver is not properly functioning, which is a critical issue that requires immediate attention.

Monitoring for these symptoms is essential for patient safety, particularly since tacrine is known to cause liver damage in some cases. Understanding this connection allows healthcare professionals to proactively manage potential side effects, ensuring better outcomes for individuals under their care.
