The nurse is caring for a client with a head injury. When administering mannitol (Osmitrol), which precaution should the nurse take? A. Obtain a filter for the IV tubing B. Have flumazenil (Romazicon) available at the bedside C. Hyperventilate the client before administration D. Assess the client's WBC count

Mannitol (Osmitrol) is an osmotic diuretic primarily used for reducing intracranial pressure in clients with head injuries. Knowing the purpose of mannitol administration will make it easier to analyze the precautions mentioned in the options.

Let's examine each of the given options one-by-one: A. Obtain a filter for the IV tubing: Mannitol has a tendency to crystallize at lower temperatures, therefore, using a filter during the administration of mannitol via IV tubing is advised. B. Have flumazenil (Romazicon) available at the bedside: Flumazenil (Romazicon) is an antidote used to reverse the effects of benzodiazepines in case of overdose. This is not directly related to the administration of mannitol. C. Hyperventilate the client before administration: Hyperventilation is not indicated before mannitol administration. Instead, hyperventilation might be used to quickly reduce intracranial pressure in emergency scenarios, but it is not directly related to mannitol infusion. D. Assess the client's WBC count: While general assessment and monitoring of a client's condition is necessary, checking the WBC count is not a specific precaution related to the administration of mannitol.

Based on the analysis of each option, the correct answer is: A. Obtain a filter for the IV tubing Using a filter during mannitol administration prevents any crystallized particles from entering the client's bloodstream.
