A nurse is preparing to administer an IV osmotic diuretic to a client with increased intracranial pressure (ICP). Which of the following should the nurse identify as the purpose of the medication?
To lower intracranial pressure by increasing urinary output.
To reduce cerebral blood flow.
To prevent the formation of cerebral edema.
To decrease brain oxygen consumption.
The Correct Answer is A
A. The primary purpose of administering an osmotic diuretic, such as mannitol, is to lower ICP by promoting diuresis, which results in increased urinary output and decreases fluid volume in the brain.
B. Osmotic diuretics do not specifically reduce cerebral blood flow; rather, they work by reducing fluid volume and thus intracranial pressure.
C. While osmotic diuretics can help manage edema, their primary role is not solely to prevent the formation of cerebral edema but to actively reduce existing pressure.
D. Osmotic diuretics do not directly decrease brain oxygen consumption; their main function is to create an osmotic gradient that pulls fluid from the brain to reduce ICP.

Correct Answer is C
Explanation
A. Feeling fatigued is not indicative of a therapeutic response; rather, patients should experience increased energy levels with appropriate therapy.
B. Decreased thyroxine levels are not the primary goal of levothyroxine therapy, which aims to normalize thyroid hormone levels in the body.
C. Decreased thyroid-stimulating hormone (TSH) levels indicate that the body is responding well to levothyroxine, as TSH production decreases when thyroid hormone levels are adequate.
D. Bradycardia and hypotension are not desired effects of levothyroxine and indicate potential under-treatment or other issues rather than a therapeutic response.
Correct Answer is B
Explanation
A. While reporting dizziness is important, it does not directly aid in managing vertigo episodes.
B. Instructing the client to get up slowly while turning their entire body helps to reduce vertigo symptoms by minimizing head movement, which can trigger or worsen dizziness in Meniere’s disease.
C. Driving is not recommended during symptomatic periods of vertigo, as it could be unsafe.
D. The logroll technique is typically used for clients with spinal issues rather than vertigo management in Meniere’s disease.
