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

Cerebellar injury affects balance and coordination; ensuring bed alarm use prioritizes safety for patients who are at high fall risk due to impaired motor control and unsteady gait.

Choice B rationale

Reorientation addresses confusion, often linked to cognitive or frontal brain injuries, not cerebellar function, which mainly regulates coordination and balance rather than higher-order thinking.

Choice C rationale

Turning every 2 hours prevents skin breakdown but is more relevant to immobilized patients, not those with cerebellar injuries where mobility and fall prevention are the primary concerns.

Choice D rationale

Varying the schedule may stimulate engagement but does not directly address fall risks or coordination issues, which are critical for patients with cerebellar injuries.
