Final answer:
The team should consult with a geriatric psychiatrist or dementia specialist.
Step-by-step explanation:
The next step the team should take when considering starting Jack on an antipsychotic medication is to consult with a geriatric psychiatrist or dementia specialist. This is important because these specialists have expertise in managing behavioral and psychological symptoms associated with dementia and can provide guidance on the most appropriate treatment plan for Jack. They will be able to assess Jack's condition, evaluate the risks and benefits of starting antipsychotic medication, and consider alternative strategies to manage his combative behavior.
Increasing staff intervention during showers (option c) and modifying the shower routine (option d) may be effective strategies, but it is crucial to consult with a specialist before implementing these changes. Starting an antipsychotic medication immediately (option a) without consulting a specialist can lead to potential side effects and may not address the underlying causes of Jack's behavior. Therefore, option b is the best next step for the team to take.
