After receiving pre procedural instructions, which patient statement demonstrates an understanding of a scheduled ventriculostomy?
"I won't be able to have drugs instill through this procedure."
"I will have an internal transducer inserted into my head."
"The healthcare provider won't be able to get samples of my cerebrospinal fluid."
"It will directly measure the pressure within the ventricles of my brain."
The Correct Answer is D
A. A ventriculostomy involves inserting a catheter into the ventricles of the brain to monitor ICP, not a procedure for instilling drugs.
B. A ventriculostomy involves the insertion of a catheter to monitor ICP, not an internal transducer.
C. Cerebrospinal fluid (CSF) samples can be taken via ventriculostomy; the procedure does not prevent this.
D. A ventriculostomy measures the pressure within the brain’s ventricles to monitor intracranial
pressure, which is the correct understanding.
