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.

Correct Answer is A
Explanation
A. Ventriculostomy is considered the gold standard for measuring intracranial pressure (ICP). This procedure involves placing a catheter into the brain's ventricles to directly measure the pressure inside the skull.
B. Fiberoptic catheter can also be used for ICP measurement, but ventriculostomy is more accurate and allows for drainage of cerebrospinal fluid if needed.
C. Central line is used for venous access, not for measuring ICP.
D. Transcranial Doppler is used to assess blood flow in the brain, but not for direct ICP measurement.
Correct Answer is B
Explanation
A. Placing the client in a supine position may increase ICP; the nurse should elevate the head of the bed to 30 degrees to reduce pressure.
B. Log rolling to reposition the client helps maintain spinal alignment and prevent further injury without increasing ICP.
C. Coughing and deep breathing should be avoided as they can increase ICP.
D. A warming blanket could cause vasodilation and worsen ICP.
