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 C

Explanation

Choice A rationale

Monitoring frequency of urination indicates bladder involvement, often related to cystitis. However, it does not indicate ascending progression to the kidneys, which is more severe and requires additional symptoms.

Choice B rationale

Dysuria, or painful urination, typically signifies lower urinary tract infection rather than progression to upper urinary tract infection, such as pyelonephritis. It is not specific to kidney involvement.

Choice C rationale

Flank pain and fever are hallmark symptoms of pyelonephritis, indicating ascending progression of infection from the bladder to the kidneys. These symptoms signal systemic involvement and require immediate medical attention.

Choice D rationale

Pyuria and hematuria are signs of bladder infection but do not indicate progression to kidney infection. These are specific to inflammation or infection in the lower urinary tract.

A. Patient's heart rate is 62 and regular. B. Patient is able to lie flat without reporting difficulty breathing. C. Patient does not report dyspnea after climbing one flight of stairs. D. Patient has weight loss of 3 lbs (1.4 kg) over 2 weeks.

Correct Answer is A

Explanation

Choice A rationale

Metoprolol decreases cardiac workload by reducing heart rate and myocardial oxygen demand. A heart rate of 62 is within normal limits, demonstrating effective beta-blocker action and improved cardiac efficiency.

Choice B rationale

Lying flat without difficulty breathing reflects improved respiratory status, which is more related to pulmonary management, not directly indicative of reduced cardiac workload or beta-blocker efficacy.

Choice C rationale

Absence of dyspnea after climbing stairs suggests improved physical fitness but does not directly measure the cardiac effects of metoprolol, which targets heart rate reduction and myocardial oxygen use.

Choice D rationale

Weight loss is related to overall health improvement or dietary changes rather than specific effects of metoprolol, which primarily impacts heart rate and cardiac oxygen consumption.
