The nurse is preparing to administer 1600 mL of total parental nutrition (TPN) over 24 hours.

The nurse should set the IV pump to deliver how many mL/hr?

Choice A rationale

Reviewing the safety data sheet does not directly alleviate the immediate chemical injury or prevent further damage. Immediate irrigation of the eyes is the priority after chemical exposure to minimize damage to the ocular surface.

Choice B rationale

Continuous irrigation removes chemical agents from the eyes and prevents further damage. Ensuring a pain-free state and checking pH confirm the removal of irritants, essential for preventing deeper eye tissue damage.

Choice C rationale

Miotic drops reduce intraocular pressure but do not address acute chemical injury. Pain relief is secondary to irrigating and neutralizing pH, which directly prevents ongoing tissue damage and irritation.

Choice D rationale

Assessing visual acuity and vital signs is important but secondary to preventing further chemical penetration. Immediate irrigation prevents damage progression and is prioritized over assessments during the acute phase of exposure.

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.
