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.

Explanation
A client with expiratory wheezing after an albuterol treatment.
This indicates that the client has a severe bronchospasm that is not responding to the medication and may lead to respiratory failure.
The client needs immediate intervention to improve airway patency and oxygenation.
Choice A is wrong because a fasting blood sugar of 187 mg/dL is high but not life- threatening. The normal range for fasting blood sugar is less than 99 mg/dL.
The client may have diabetes or prediabetes and needs further evaluation and treatment, but this is not a priority over choice B.

Correct Answer is ["A","C","D"]
Explanation
These are natural respiratory defense mechanisms that help defend against infection.
Choice A is correct because cilia lining the respiratory tract sweep debris upward in mucus to be swallowed.
This prevents pathogens and particles from reaching the lungs.
Choice B is wrong because the respiratory tract does not cool and dry the air being inhaled. In fact, the respiratory tract warms and humidifies the air to facilitate gas exchange.
Choice C is correct because cells in the respiratory tract secrete lysozymes that can destroy certain bacteria.
Lysozymes are enzymes that break down the cell walls of bacteria.
Choice D is correct because macrophages engulf and destroy bacteria found in the alveoli. Macrophages are a type of white blood cell that act as scavengers of foreign invaders.
Choice E is wrong because high concentrations of oxygen and carbon dioxide do not aid the defense mechanisms.
On the contrary, high levels of these gases can impair gas exchange and cause acid-base imbalance.
