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

Symmetry of extraocular movements assesses cranial nerve function but does not relate to the corrective purpose of bifocals, which is addressing near and distant vision issues caused by presbyopia and myopia.

Choice B rationale

Bifocals correct presbyopia and myopia by combining lenses for near and distant vision in one frame. Effectiveness is assessed by evaluating improvements in both visual ranges, ensuring accommodation and refraction are properly corrected.

Choice C rationale

Cloudiness in the lens indicates cataracts, which bifocals cannot correct. Cataracts require surgical intervention, making this assessment irrelevant to determining bifocal lens effectiveness for presbyopia and myopia.

Choice D rationale

Intraocular pressure changes relate to glaucoma, not refractive issues like myopia or presbyopia. Monitoring for glaucoma requires tonometry, independent of bifocal lens evaluation.

Choice A rationale

While bleeding could indicate trauma, EEG does not detect blood presence or volume but instead evaluates electrical brain activity indicative of neuronal function.

Choice B rationale

Cerebral oxygen intake assessment requires pulse oximetry or arterial blood gas analysis rather than EEG, which monitors electrical signals, not oxygenation status.

Choice C rationale

EEG identifies abnormal brain wave patterns suggesting ongoing seizure activity, even in sedated patients, aiding in targeted interventions and preventing potential complications.
