Progressive brain disorder that causes uncontrolled movements, emotional problems, and cognitive dysfunction.

A. Naltrexone is used to help manage alcohol dependence by reducing cravings and the pleasurable effects of alcohol. It blocks opioid receptors in the brain, which can help prevent relapse in people trying to stop drinking.
B. Valium (diazepam) is a benzodiazepine, typically used to treat anxiety, muscle spasms, and alcohol withdrawal symptoms, but it is not specifically used as a medication for alcoholism treatment itself. While it may be used during withdrawal to manage symptoms, it is not a medication for long-term management of alcohol dependence.
C. Antabuse (disulfiram) is used to deter drinking by causing unpleasant reactions (such as nausea and vomiting) if alcohol is consumed. This is a treatment for alcoholism that relies on the patient's compliance to avoid drinking.
D. Campral (acamprosate) is used to help people maintain abstinence from alcohol after they've stopped drinking. It works by restoring the balance of neurotransmitters in the brain that may be disrupted by long-term alcohol use.

A. Possible child abuse is the most likely assessment. The presence of numerous bruises and the mother's vague, inconsistent details about the falls are concerning and may indicate that the child is being abused. Children at this age may sustain some bumps or bruises due to falls, but repeated and unexplained injuries, especially if the mother provides few details, should raise suspicion. The nurse should report this concern to appropriate authorities for further investigation.
B. Knowledge deficit pertaining to home safety could be a possibility if the mother is unaware of safety precautions in the home, but the vague and inconsistent explanation of the injuries makes this less likely. A knowledge deficit would typically present with more specific concerns and less concern for frequent injury.
C. A child with delayed milestones does not explain the frequent bruises or the vague details provided by the mother. While developmental delays can occur in some children, they are unlikely to account for such a pattern of injuries.
D. Normal behavior for a 2-year-old typically involves some bumps and bruises, but frequent falls resulting in numerous bruises are not considered normal. Most 2-year-olds are still learning motor skills, but they should not be falling down stairs repeatedly.
