Final answer:
The nurse would prepare the patient for the placement of a ventriculoatrial shunt, which involves implanting a device in the patient's brain to remove excess cerebrospinal fluid.
Step-by-step explanation:
The nurse would prepare the patient for the placement of a ventriculoatrial shunt. This surgical procedure involves implanting a device called a shunt in the patient's brain to remove excess cerebrospinal fluid (CSF). The shunt consists of a small tube, called a catheter, which is inserted into the patient's ventricles. The CSF is then drained through a one-way valve to the other end of the shunt, which is threaded under the patient's skin to their abdominal cavity, where the CSF is released and reabsorbed by the bloodstream.
