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.

Answer and Explanation

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. While pain level assessment is important, it is not the priority immediately after a significant brain injury where neurological changes may occur.
B. Wound site assessment is also essential but does not take precedence over neurological assessment in this context.
C. A neurological assessment is the priority to identify any changes in the client's condition that may indicate complications such as increased intracranial pressure, which can occur after brain surgery.
D. Respiratory status assessment is important but is usually addressed through monitoring and interventions related to neurological function, as brain injuries can affect respiratory drive and function.

A. Encouraging the client to perform deep breathing exercises. B. Elevating the head of the bed. C. Administering a sedative. D. Monitoring intracranial pressure (ICP).

Correct Answer is D

Explanation

A. Encouraging deep breathing exercises may help with respiratory function but does not address the immediate risks associated with increased ICP.
B. Elevating the head of the bed can help reduce ICP; however, the priority intervention is to closely monitor ICP to identify any changes in the client's condition.
C. Administering a sedative may be appropriate, but it is not as critical as monitoring ICP in a client with Cushing's Triad, where altered consciousness and respiratory changes may be present.
D. Monitoring ICP is crucial in this situation, as Cushing's Triad indicates a potential increase in ICP, and timely interventions can prevent further complications.
