A nurse is collecting data from an infant who is postoperative. Which of the following pain scales should the nurse use to evaluate the infant's pain level?

A. Oral irrigating device: An oral irrigating device is used for oral hygiene but is not a priority for a client with bacterial meningitis. Infection control and safety interventions take precedence over routine hygiene equipment upon admission.

B. Seizure pads: Clients with bacterial meningitis are at risk for increased intracranial pressure and seizures due to inflammation of the meninges. Placing seizure pads on the bed helps prevent injury if a seizure occurs, ensuring client safety during acute illness.

C. Sterile gloves: Standard precautions require the use of clean gloves for routine care. Sterile gloves are necessary only for invasive procedures, not for general admission care, so they are not a priority item for the room setup.

D. Tongue blade: A tongue blade is used for throat examinations but is not essential for immediate care of a client with bacterial meningitis. Priority interventions focus on monitoring neurologic status and preventing complications such as seizures.

A. Sudden dimmed vision: Sudden vision changes are more indicative of acute ocular events such as retinal detachment, vitreous hemorrhage, or acute glaucoma. Cataracts typically progress slowly over months to years, producing gradual changes in visual clarity rather than abrupt dimming. Sudden visual loss warrants immediate evaluation for emergent conditions.

B. Cloudy vision: Cloudy or blurred vision is a hallmark symptom of cataracts, resulting from progressive opacification of the lens. As light passes through the lens, scattering and reduced transparency interfere with clear image formation on the retina. Clients often report difficulty reading, glare from bright lights, or seeing halos around lights due to this lenticular clouding.

C. Intermittent flashes of light: Flashes of light are usually associated with retinal traction or detachment, indicating that the retina is being mechanically stimulated. These visual phenomena are not typical of cataracts, which involve gradual lens opacity rather than retinal irritation or mechanical disruption.

D. Pain in the eyes: Cataracts are generally painless because they involve lens opacification rather than inflammatory or pressure-related ocular pathology. Eye pain is more characteristic of conditions such as acute angle-closure glaucoma, uveitis, or corneal abrasions, which involve increased intraocular pressure or direct tissue irritation.
