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.
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
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.
Correct Answer is ["A","B","C"]
Explanation
Choice A rationale
Proper nutrition, exercise, and stress reduction enhance psychological well-being, stimulating endorphin release, which improves mood and resilience, essential for managing chronic conditions like HIV.
Choice B rationale
These factors bolster immune function by reducing cortisol levels that impair immunity, supporting T-cell activity and promoting resistance against opportunistic infections common in HIV patients.
Choice C rationale
Maintaining strength and independence aids patients in daily functioning, reducing dependency and enhancing self-efficacy, which is critical for long-term adherence to therapeutic regimens in HIV.
Choice D rationale
Preventing virus transmission requires safe practices, not lifestyle changes alone. Nutrition and exercise cannot alter transmission mechanisms like exposure to body fluids.
Choice E rationale
Eliminating HIV completely necessitates antiretroviral therapy and advancements in medical science; lifestyle modifications alone are insufficient against viral integration within host DNA.
