A 68-year-old client diagnosed with cataracts should be assessed for which finding?
Blurred or cloudy vision.
Burning sensation in the eye.
Inability to produce tears.
A swollen lacrimal gland.
The Correct Answer is A
Cataracts are a condition where the lens of the eye becomes opaque, causing impaired vision. Blurred or cloudy vision is a common symptom of cataracts.
Some possible explanations for the other choices are:
Choice B. Burning sensation in the eye. This is not a typical symptom of cataracts, but it could indicate an infection, allergy, or dry eye syndrome.
Choice C. Inability to produce tears. This is also not a typical symptom of cataracts, but it could indicate a problem with the lacrimal glands or ducts that produce and drain tears.
Choice D. A swollen lacrimal gland. This is not a symptom of cataracts, but it could indicate an inflammation or infection of the lacrimal gland, which is located near the upper eyelid.
Normal ranges for visual acuity are 20/20 for normal vision and 20/40 for mild impairment. Visual acuity can be measured using a Snellen chart or other methods.

Correct Answer is A
Explanation
This is because the first priority for assessing an elderly client who has become confused since admission is to rule out hypoxia, which can cause or worsen delirium. Hypoxia can result from various conditions, such as pneumonia, pulmonary embolism, or heart failure.
Oxygen saturation measurement is a quick and non-invasive way to assess the oxygen level in the blood and identify hypoxia.
Choice B. Review of current medications is wrong because although medications can cause or contribute to confusion and delirium in older adults, they are not the most urgent assessment to perform.
Medications should be reviewed after ensuring adequate oxygenation and addressing other possible causes of confusion.
Choice C. Intake and output last 24 hours is wrong because although dehydration and electrolyte imbalance can cause or worsen confusion and delirium in older adults, they are not the most urgent assessment to perform.
Intake and output should be monitored after ensuring adequate oxygenation and addressing other possible causes of confusion.
Choice D. Use of hearing aids or glasses is wrong because although sensory impairment can cause or worsen confusion and delirium in older adults, it is not the most urgent assessment to perform.
The use of hearing aids or glasses should be ensured after ensuring adequate oxygenation and addressing other possible causes of confusion.
Normal ranges for oxygen saturation are 95% to 100% for healthy adults. Lower levels may indicate hypoxia or other respiratory or cardiac problems.
Correct Answer is D
Explanation
Levofloxacin (Levaquin) is a fluoroquinolone antibiotic that is not structurally related to penicillin and has a very low risk of cross-reactivity with penicillin.
Levofloxacin can be safely used in patients with penicillin allergy unless they have a history of hypersensitivity to other fluoroquinolones.
Choice A is wrong because cephalexin (Keflex) is a first-generation cephalosporin that has a similar side chain to some penicillins and may cause cross-reactivity in penicillin-allergic patients. The risk of cross-reactivity is higher for first- and second-generation cephalosporins than for third- and fourth-generation cephalosporins.
Choice B is wrong because cefaclor (Ceclor) is a second-generation cep
