A 64-year-old client is prescribed bifocals to correct myopia and presbyopia.
To evaluate the effectiveness of the lenses, the nurse will assess the client for:

Symmetry of extraocular movement.

Both near and distant vision.

Cloudiness in the lens of the eye.

Intraocular pressure changes.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is A

Explanation

Choice A rationale

A ketogenic diet includes high fats, moderate protein, and low carbohydrates, with unsaturated fats emphasized for health. This metabolic state reduces seizure frequency by enhancing ketone production as an alternative energy source for the brain.

Choice B rationale

Increasing carbohydrates disrupts ketosis, the fundamental principle of the ketogenic diet. This would counteract the therapeutic goal of reducing seizure activity by providing glucose as a primary brain fuel instead of ketones.

Choice C rationale

While omega-3 oils support brain health, the ketogenic diet focuses on low carbohydrate intake and high fat. Moderate protein intake is essential, but excess omega-3 emphasis neglects the diet’s structure.

Choice D rationale

Foods high in sodium and carbohydrates contradict the ketogenic diet's principles. Elevated carbohydrate intake halts ketosis, while excess sodium intake is unrelated to ketogenic mechanisms or seizure management.

A. By threading it through the femoral artery to the brain. B. To monitor intracranial pressure (ICP) and drain cerebral spinal fluid. C. After the patient has an electroencephalogram (EEG). D. Due to having minimal risk for infection.

Correct Answer is B

Explanation

Choice A rationale

Ventriculostomies are inserted directly through the skull into the ventricles, not via the femoral artery. This method provides direct access to cerebrospinal fluid for drainage and pressure monitoring.

Choice B rationale

Ventriculostomies are placed to monitor intracranial pressure and drain excess cerebrospinal fluid, managing conditions like hydrocephalus or elevated intracranial pressure following brain injury or surgery.

Choice C rationale

An EEG monitors electrical brain activity but is unrelated to ventriculostomy placement. Ventriculostomy focuses on fluid drainage and pressure management, not on electrical diagnostic procedures.

Choice D rationale

Ventriculostomies carry a significant risk of infection due to the invasive nature of the procedure. Proper aseptic technique is critical to minimizing, not eliminating, the risk of infection.
