When caring for a client receiving mannitol via IV infusion, which adverse effect should the nurse monitor for?

Mannitol is an osmotic diuretic that is primarily used to reduce intracranial pressure and treat conditions such as cerebral edema and glaucoma. When administering mannitol, it is important to monitor for specific adverse effects related to its mechanism of action.

One of the key adverse effects to monitor for when a client is receiving mannitol via IV infusion is the development of bibasilar crackles, which can indicate pulmonary edema. Mannitol causes an osmotic diuresis, leading to increased urine output. If the kidneys are unable to effectively eliminate the excess fluid and solutes, this can result in fluid overload. The pulmonary system may then exhibit signs of this overload, such as crackles upon auscultation, especially in the bases of the lungs.

In contrast, weight loss is not typically an adverse effect associated with mannitol. Increased intraocular pressure is also contrary to the therapeutic intent of mannitol, which aims to reduce eye pressure. Auditory hallucinations are not directly related to mannitol use and are more indicative of a neurological or psychiatric issue rather than a common adverse effect of this medication. Understanding these specific effects helps guide appropriate monitoring and intervention for patients receiving mannitol.
