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 C
Explanation
The proper length of the needle to administer a subcutaneous injection depends on the amount of adipose tissue over the muscle.
The needle should be long enough to reach the subcutaneous layer but not so long that it penetrates the muscle. The needle gauge and length vary depending on the patient’s size and the injection site
Choice A is wrong because the age of the client does not determine the needle length.
However, age may affect the amount of adipose tissue and muscle mass, which are factors to consider when choosing a needle length.
Choice B is wrong because the viscosity of the solution does not determine the needle length. However, viscosity may affect the needle gauge, which is the diameter of the needle.
Thicker solutions may require larger gauge needles to allow easier flow.
Choice D is wrong because the quantity of the solution does not determine the needle length.
However, quantity may affect the syringe size, which is the volume of medication that can be held by the syringe.
The syringe size should match the prescribed dose as closely as possible to ensure accuracy and ease of measurement.
Correct Answer is C
Explanation
Motrin is a brand name for ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID). NSAIDs can cause renal toxicity, especially in older adults and patients with renal disease.
Therefore, the nurse should be most concerned about this medication and its potential adverse effects on the patient’s kidney function.
Choice A is wrong because digoxin is a cardiac glycoside that is used to treat heart failure and atrial fibrillation. Digoxin has a narrow therapeutic index and can cause toxicity if the dose is too high or if the patient has hypokalemia. However, digoxin does not directly affect the kidneys and can be safely used in patients with renal disease if the dose is adjusted according to the patient’s creatinine clearance.
Choice B is wrong because levothyroxine is a synthetic thyroid hormone that is used to treat hypothyroidism. Levothyroxine does not have any major interactions with the kidneys and can be used in patients with renal disease without dose adjustment.
Choice D is wrong because Tylenol is a brand name for acetaminophen, which is an analgesic and antipyretic drug. Acetaminophen does not have any anti-inflammatory effects and does not affect the kidneys at therapeutic doses. However, acetaminophen can cause hepatotoxicity if the dose exceeds 4 g per day or if the patient has liver disease or alcohol abuse.
