Final answer:
Nurses should monitor for anorexia, dizziness, headache, constipation, and bradycardia as potential adverse effects in clients taking donepezil (Aricept), which can influence both the gastrointestinal and cardiovascular systems.
Step-by-step explanation:
When monitoring a client taking donepezil (Aricept), a nurse should be aware of several potential adverse effects. These include anorexia, dizziness, and headache, which are common responses to this medication. Additionally, gastrointestinal issues such as constipation or diarrhea can occur. It is also important to monitor for signs of bradycardia, a lower-than-normal heart rate, as donepezil can influence heart rhythm. Monitoring these adverse effects is crucial for ensuring patient safety and managing any complications that may arise from the medication.
