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: An altered level of consciousness is not typically associated with Alzheimer's disease. Patients with Alzheimer's may experience confusion or disorientation, but changes in consciousness, such as stupor or coma, are not characteristic symptoms of the disease.

Choice B reason: Failure to recognize familiar objects, known as agnosia, is a common finding in Alzheimer's disease. As the disease progresses, the ability to recognize objects, faces, and even sounds can be impaired, which is a direct result of the deterioration of brain areas involved in processing sensory information.

Choice C reason: Excessive motor activity is not a common finding in Alzheimer's disease. While patients may experience restlessness, the disease often leads to a decrease in overall activity levels due to cognitive decline and the eventual difficulty with coordination and motor functions.

Choice D reason: Rapid mood swings can occur in Alzheimer's disease, but they are not as prominent as other cognitive symptoms. Mood changes in Alzheimer's are usually a result of the frustration and confusion experienced by the patient rather than a direct symptom of the disease itself.

Choice A reason: This statement may seem supportive, but it does not address the immediate safety concerns for a client with suicidal ideations and a verbalized plan. Submitting a request for privacy does not mitigate the risk of harm the client may pose to themselves.

Choice B reason: This is the most appropriate response because it directly addresses the safety of the client, which is the primary concern in this situation. It communicates care and concern while also reinforcing the need for observation due to the risk of suicide.

Choice C reason: While safety contracts can be a part of a comprehensive treatment plan, they are not foolproof and should not replace close observation for a client who has expressed suicidal ideations and has a plan. Relying solely on a contract in this situation could be dangerous.

Choice D reason: This statement is factual in that medication levels need to be therapeutic; however, it does not directly address the immediate risk of suicide. Constant observation is required regardless of medication levels if a client has verbalized a plan for suicide.
