The nurse knows that an important contraindication for valproic acid use is:

Choice A rationale

Applying pressure to prevent drainage could force cerebrospinal fluid (CSF) back into the cranial cavity, increasing infection risk and intracranial pressure, potentially worsening brain injury. CSF leakage requires non-obstructive handling.

Choice B rationale

Allowing fluid to drain onto gauze prevents build-up of intracranial pressure while assessing for halo sign, indicating CSF leakage. Yellow staining reflects glucose presence in CSF, confirming dura mater damage.

Choice C rationale

Intravenous fluids manage hypovolemia but are not prioritized for trauma patient brain injuries. Replacing lost CSF requires specific medical intervention rather than fluid volume adjustments alone.

Choice D rationale

Antibiotics treat infections but are not first priority for confirmed CSF leakage, which demands careful monitoring of drainage to prevent neurological damage. Post-intervention antibiotics may be necessary.

Choice A rationale

Fluid intake does not directly impact intraocular pressure. Management of glaucoma focuses on medications like eye drops and surgical interventions rather than restricting fluid intake.

Choice B rationale

Glaucoma treatments, including eye drops, aim to manage intraocular pressure. These medications are required lifelong to prevent optic nerve damage and preserve vision.

Choice C rationale

Excess salt impacts systemic blood pressure but does not directly influence intraocular pressure. Glaucoma management targets ocular pressure, not dietary sodium reduction.

Choice D rationale

Avoiding eye overuse may reduce strain but does not address intraocular pressure. Effective glaucoma treatment relies on pharmacological or surgical measures rather than activity limitation.
