A nurse admits a client who has a subarachnoid hemorrhage and increased intracranial pressure (ICP). Which of the following medications should the nurse expect to administer to decrease ICP?
A. Dopamine
Dopamine: Dopamine is a catecholamine often used to increase blood pressure and cardiac output in hypotensive states. It does not directly reduce intracranial pressure (ICP).
B. Mannitol
Mannitol: Mannitol is an osmotic diuretic commonly used to reduce intracranial pressure in clients with conditions such as subarachnoid hemorrhage, traumatic brain injury, or cerebral edema. It works by drawing fluid from brain tissue into the bloodstream, thereby reducing cerebral edema and ICP.
C. Nicardipine
Nicardipine: Nicardipine is a calcium channel blocker used primarily to lower blood pressure in hypertensive emergencies. While it can indirectly impact intracranial pressure by reducing cerebral perfusion pressure, its primary mechanism of action is not targeted at reducing ICP.
D. Phenytoin
Phenytoin: Phenytoin is an antiepileptic medication used to prevent and control seizures. While it may be indicated in clients who have experienced a subarachnoid hemorrhage to prevent seizures, it does not directly reduce intracranial pressure.

A nurse is caring for a client in the intensive care unit who suddenly becomes confused and agitated. The nurse recognizes these manifestations are likely related to a condition with which of the following characteristics?
A. Isolated
Isolated: This term refers to something that is separate or distinct. Confusion and agitation in a client are not typically isolated but can be part of a broader clinical picture.
B. permanent
Permanent: These manifestations are not typically permanent and can often be reversed with appropriate interventions.
C. Reversible
Reversible: Confusion and agitation in a client are often reversible and can be due to various factors such as medications, infections, metabolic disturbances, or other medical conditions. Identifying and addressing the underlying cause can often restore the client to their baseline mental status.
D. Unique
Unique: While every individual's presentation may have unique aspects, confusion and agitation are not considered unique manifestations in the context of acute changes in mental status. They are common symptoms that can occur due to a variety of reasons and are not exclusive to any particular condition.

A nurse is assessing a client who has Lewy body dementia. The nurse should recognize that which of the following is responsible for changes in thinking, communication, movement, and emotional processing in Lewy body dementia?
A. Tau protein
Tau protein: Tau protein is primarily associated with Alzheimer's disease and other tauopathies, not Lewy body dementia.
B. Neurofibrillary tangles
Neurofibrillary tangles: Neurofibrillary tangles are aggregates of hyperphosphorylated tau protein found in Alzheimer's disease, not typically in Lewy body dementia.
C. Alpha-synuclein protein
Alpha-synuclein protein: Lewy bodies, which are abnormal aggregates of alpha-synuclein protein, are a hallmark pathology of Lewy body dementia. These protein aggregates disrupt neuronal function and are responsible for the cognitive, motor, and emotional symptoms seen in Lewy body dementia.
D. Beta-amyloid protein
Beta-amyloid protein: Beta-amyloid protein is primarily associated with Alzheimer's disease, not Lewy body dementia. It forms plaques in the brain, which contribute to neurodegeneration and cognitive decline in Alzheimer's disease.

A nurse is collecting data from an admission history for a client who reports being tackled while playing football and is now seeing bright flashes of light and dark floating spots. Which of the following conditions should the nurse expect the client to be experiencing?
A. Open-angle glaucoma
Open-angle glaucoma: Open-angle glaucoma typically presents with increased intraocular pressure and gradual loss of peripheral vision, not with bright flashes of light and dark floating spots.
B. Macular degeneration
Macular degeneration: Macular degeneration is characterized by central vision loss, not by bright flashes of light and dark floating spots.
C. Meniere’s disease
Meniere’s disease: Meniere’s disease is a disorder of the inner ear characterized by episodes of vertigo, hearing loss, and tinnitus. It does not typically cause bright flashes of light and dark floating spots in the visual field.
D. Retinal detachment
Retinal detachment: Trauma, such as being tackled while playing football, can lead to retinal detachment, which can manifest with symptoms such as bright flashes of light (photopsia) and dark floating spots (floaters) in the affected eye. This condition is considered a medical emergency and requires prompt evaluation and treatment to prevent permanent vision loss.
