Which assessment finding requires immediate intervention for a patient receiving Mannitol?

Mannitol is an osmotic diuretic used primarily to reduce intracranial pressure (ICP) in patients with cerebral edema or traumatic brain injuries. It works by creating an osmotic gradient that pulls fluid into the vascular space, which can subsequently lead to a decrease in cerebral volume and pressure. However, one of the significant complications associated with Mannitol therapy is fluid overload, which can result in pulmonary edema.

When a patient receiving Mannitol exhibits crackles throughout the lung fields, this finding is indicative of fluid accumulation in the lungs. This suggests that the patient may be experiencing pulmonary edema, a serious condition that requires immediate intervention. The presence of crackles can interfere with adequate oxygenation and may precipitate respiratory failure if not addressed promptly.

In contrast, an ICP of 10 mmHg is within normal limits (normal ICP ranges from 7 to 15 mmHg) and does not necessitate immediate action. A blood pressure of 110/72 is also stable and does not indicate an acute problem. Similarly, while complaints of dry mouth and thirst can be noted, they typically signal minor discomfort rather than a critical issue needing urgent intervention.

Given the potential seriousness of pulmonary edema, the presence of crackles is a clear indication that immediate action
