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","B"]
Explanation
A client with dehydration will have increased heart rate and decreased blood pressure due to the loss of fluid volume and the compensatory mechanisms to maintain cardiac output.
Choice C is wrong because dehydration does not cause increased temperature, but rather decreased temperature due to reduced blood flow to the skin.
Choice D is wrong because dehydration causes hyperactive muscle responses, such as muscle cramps, twitching, and tetany.
Choice E is wrong because dehydration can cause altered mental status, such as confusion, lethargy, or coma. Normal ranges for heart rate are 60-100 beats per minute, blood pressure is 120/80 mm Hg, and temperature is 36.5-37.5°C (97.7-99.5°F).
Correct Answer is D
Explanation
30 mL. This is because one ounce is equal to 29.57353 milliliters, so one ounce of an elixir medication is approximately 30 milliliters.
The nurse should instruct the client to take 30 milliliters of the medication during discharge teaching.
Choice A is wrong because 5 milliliters is much less than one ounce. Choice B is wrong because 15 milliliters is half of one ounce.
Choice C is wrong because 25 milliliters is slightly less than one ounce.
The nurse should use a conversion factor or a calculator to convert ounces to milliliters accurately.
