A nurse is providing teaching to a client with Meniere's disease. The nurse recognizes that which of the following instructions should be given to the client regarding vertigo?
Report dizziness at once.
Get up slowly, turning the entire body.
Drive in daylight hours only.
Change your position using the logroll technique.
The Correct Answer is B
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.

Correct Answer is B
Explanation
A. Hormone replacement is generally used to supplement deficiencies rather than inhibit excess hormone release.
B. Dopamine agonists, such as bromocriptine, are used to inhibit the release of growth hormone from the anterior pituitary, which is beneficial in treating acromegaly, a condition caused by excess growth hormone.
C. Levothyroxine is a thyroid hormone replacement and is not effective in controlling pituitary hormone release.
D. Corticosteroids do not inhibit growth hormone release and are typically used to manage inflammation rather than for pituitary hormone control.
Correct Answer is A
Explanation
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.
