A nurse is teaching the family of an older adult client who has a new diagnosis of dementia. Which of the following statements should the nurse include in the teaching?
"Dementia is characterized by a sudden onset of confusion."
"Dementia can be triggered by a high fever or dehydration."
"An altered level of consciousness is associated with dementia."
"The signs of dementia are progressive and irreversible."
The Correct Answer is D
Choice A Rationale: Dementia is not characterized by a sudden onset of confusion. It is a gradual and progressive condition.
Choice B Rationale: Dementia can be triggered or worsened by factors like infections, but it is not primarily characterized by a high fever or dehydration.
Choice C Rationale: An altered level of consciousness is not typically associated with dementia but may occur in acute delirium.
Choice D Rationale: The nurse should explain to the family that dementia is a chronic condition that affects the brain and causes cognitive impairment, memory loss, and behavioral changes. The nurse should also inform the family that dementia is not caused by a single factor, but by a combination of genetic, environmental, and lifestyle factors. The nurse should emphasize that dementia is not a normal part of aging, and that it has different stages and types.

Correct Answer is D
Explanation
Choice A Rationale: Guillain-Barre syndrome does not typically cause enlargement of parotid and salivary glands, leading to drooling.
Choice B Rationale: Obstructed blood flow to the brain is not the primary cause of the described symptoms in Guillain-Barre syndrome.
Choice C Rationale: Deficiency of thiamine and pyridoxine in the central nervous system is not a characteristic feature of Guillain-Barre syndrome.
Choice D Rationale: In Guillain-Barre syndrome, demyelination affects cranial nerves responsible for swallowing and the gag reflex, leading to difficulties in swallowing secretions and drooling.
Correct Answer is A
Explanation
Choice A Rationale: Assessing the client for bladder distention is the first and most crucial step in managing autonomic dysreflexia. Bladder distention is a common trigger for this condition in clients with spinal cord injuries. Identifying and addressing the cause (bladder distention) is the priority to prevent further complications.
Choice B Rationale: Laying the client flat may not resolve the underlying cause of autonomic dysreflexia and should be done after identifying and addressing the trigger.
Choice C Rationale: Obtaining the client's heart rate is important but should come after assessing for bladder distention since the primary concern in autonomic dysreflexia is elevated blood pressure due to a noxious stimulus.
Choice D Rationale: Administering a nitrate antihypertensive may be necessary if other interventions do not resolve the blood pressure elevation, but it should not be the first action. Identifying and addressing the cause, such as bladder distention, is the priority.
