All of the following are risk factors for delirium except ̧

A. Prevent breakdown of acetylcholinesterase by inhibiting the action of acetylcholine is incorrect because the mechanism of Donepezil (Aricept) involves inhibiting acetylcholinesterase, not acetylcholine itself. The goal is to increase the levels of acetylcholine in the brain by preventing its breakdown.
B. Prevent breakdown of acetylcholine by inhibiting the action of acetylcholinesterase is the correct mechanism. Donepezil is a cholinesterase inhibitor. By inhibiting acetylcholinesterase (the enzyme that breaks down acetylcholine), Donepezil increases the amount of acetylcholine available to stimulate receptors in the brain, which helps improve symptoms of Alzheimer's disease.
C. Promote breakdown of acetylcholine by inhibiting the action of acetylcholinesterase is incorrect because Donepezil prevents the breakdown of acetylcholine, not promotes it.
D. Promote breakdown of acetylcholinesterase by inhibiting the action of acetylcholine is also incorrect. The purpose of Donepezil is to prevent the breakdown of acetylcholine, not to break down acetylcholinesterase itself.

A. Teach the mother about symptoms of UTI is not the nurse's first priority. While educating the mother about UTIs is important, the presence of bruises in the genital and rectal areas raises immediate concern for potential sexual abuse, which requires immediate action to ensure the child's safety.
B. Report suspected sexual abuse to protective services is the nurse's first priority. Any signs of physical trauma or injury in areas typically covered by clothing, such as the genital and rectal areas, must be reported immediately. The nurse is a mandated reporter and is legally required to report any suspected abuse. Ensuring the safety of the child is paramount, and protective services will investigate the situation and take appropriate steps.
C. Interview mother for child’s health history may be necessary later, but at this moment, the immediate concern is the possibility of sexual abuse. The nurse should report the findings to the appropriate authorities before discussing the situation further with the mother.
D. Obtain a urine sample to confirm UTI is important for diagnosing the UTI but does not address the immediate concern regarding possible abuse. The child’s safety and well-being must be prioritized, and reporting the possible abuse is more urgent than confirming the UTI at this point.
