A nurse is preparing to administer 7 mg of haloperidol IM to a client who is severely agitated. Haloperidol injection of 5 mg/mL is available. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: Notifying law enforcement within 2 hours if the person cannot be found is important, but immediate action is usually recommended in such cases. The sooner the authorities are alerted, the better the chances of locating the individual safely.

Choice B reason: Giving the most recent photo to the police is a proactive step in case the person goes missing. It can help law enforcement quickly disseminate the information and aid in the search. However, this is a reactive measure rather than a preventive one.

Choice C reason: Placing a sliding bolt lock just above the doorknob can prevent the individual from wandering, which is a common and dangerous issue in people with advanced Alzheimer's disease. This measure helps ensure the person's safety by preventing unsupervised exits from the home.

Choice D reason: Ensuring the bedroom is dark while the person is sleeping may not be advisable. Adequate night lighting is important for preventing falls if the person needs to get up during the night. A completely dark room can increase the risk of injury.

Choice A reason: Initiating hospice care services is generally considered when the client is in the final stages of Alzheimer's disease and has a life expectancy of 6 months or less. Hospice care focuses on comfort and quality of life, rather than curative treatments. It's an option when the disease has significantly progressed, not typically at the time of initial diagnosis.

Choice B reason: Transcranial magnetic stimulation (TMS) is a non-invasive procedure that uses magnetic fields to stimulate nerve cells in the brain and is being studied as a potential treatment for improving cognitive status in Alzheimer's patients. However, it is not yet a standard treatment and is considered experimental.

Choice C reason: Barbiturate medications are not typically used to control anxiety in Alzheimer's patients due to the risk of dependency and the potential to worsen cognitive impairment. Other medications, such as selective serotonin reuptake inhibitors (SSRIs), are generally preferred for managing anxiety in these patients⁷.

Choice D reason: NMDA receptor antagonists, such as memantine, are medications that can help delay cognitive symptoms in patients with moderate to severe Alzheimer's disease. They work by regulating the activity of glutamate, a neurotransmitter involved in learning and memory, which may be overactive in Alzheimer's disease.
