What is the most common cause of dementia among elderly persons?

Correct Answer: D

Rationale: Alzheimer's disease is the most common cause of dementia among elderly persons. It is a progressive neurodegenerative disorder that affects memory, thinking, and behavior. While Parkinson's disease, multiple sclerosis, and amyotrophic lateral sclerosis are serious conditions, they are not typically associated with dementia in the same way Alzheimer's disease is.

Correct Answer: B

Rationale: Before rigor mortis occurs, it is essential to place a pillow under the body's head and shoulders to maintain proper positioning. This helps prevent postmortem changes and ensures a more dignified appearance. Providing a complete bath and dressing change, removing clothing, or wrapping the body in a shroud are tasks typically done after rigor mortis sets in or later in the postmortem care process. Allowing the body to relax normally does not address the need for proper positioning before rigor mortis occurs.

Correct Answer: A

Rationale: The primary intervention during a seizure is to protect the patient from injury. This includes moving nearby objects that may harm the patient, cushioning the head, and ensuring a safe environment until the seizure subsides. Inserting an airway is not typically done during a seizure unless the patient's airway is compromised, while elevating the head of the bed is not the priority during an active seizure. Withdrawing all pain medications is not necessary unless there are specific contraindications related to the seizure event.

Rationale: The most accurate method for assessing temperature in an alert client is the oral method. It provides a more reliable reflection of the body's core temperature compared to axillary or radial methods. In cases of dehydration, it is important to get an accurate temperature reading to monitor the client's condition closely.
