A nurse is assessing the eyes on a patient and during the inspection the conjunctival sac is red, itchy, and has white thick drainage.
Which finding are these consistent with?
Allergic conjunctivitis.
Viral conjunctivitis.
Bacterial conjunctivitis.
Cataracts.
The Correct Answer is C
Choice A rationale
Allergic conjunctivitis is usually characterized by redness, itching, and watery discharge. It is often associated with allergic reactions to pollen, dust, or pet dander. The discharge in allergic conjunctivitis is typically clear and watery, not white and thick.
Choice B rationale
Viral conjunctivitis is often caused by adenovirus and is characterized by redness, watery discharge, and a gritty sensation in the eye. It is highly contagious and can spread through contact with infected individuals. The discharge in viral conjunctivitis is usually watery, not thick and white.
Choice C rationale
Bacterial conjunctivitis is characterized by redness, itching, and white, thick discharge. It is often caused by bacteria such as Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus influenzae. The thick discharge is a hallmark of bacterial infection, distinguishing it from allergic or viral conjunctivitis.
Choice D rationale
Cataracts involve the clouding of the eye's natural lens, leading to blurred vision and difficulty seeing at night. They do not cause redness, itching, or discharge from the eye. Cataracts affect the lens inside the eye, not the conjunctival sac.

Correct Answer is A
Explanation
Choice A rationale
Without treatment, glaucoma can lead to blindness due to the progressive damage it causes to the optic nerve. Elevated intraocular pressure damages the optic nerve fibers, leading to peripheral vision loss and eventually total blindness if untreated.
Choice B rationale
Double vision is not a common symptom of glaucoma. Instead, glaucoma typically presents with symptoms like gradual peripheral vision loss, eye pain, and halos around lights.
Choice C rationale
Glaucoma is primarily caused by increased intraocular pressure, either due to overproduction of aqueous humor or improper drainage, not inadequate fluid production.
Choice D rationale
Use of eye drops helps to control intraocular pressure but does not improve vision; it helps to prevent further damage to the optic nerve.
Correct Answer is D
Explanation
Choice A rationale
Scleroderma is a chronic autoimmune disorder characterized by hardening and tightening of the skin and connective tissues. While it affects the skin, it is unrelated to emphysema and bronchitis, making it an unlikely finding in this client.
Choice B rationale
Pedal erythema, or redness of the feet, can result from various causes, including infections, allergies, and circulatory issues. However, it is not commonly associated with emphysema and bronchitis, making it an unlikely finding in this client.
Choice C rationale
Anasarca is generalized body swelling due to fluid retention, often seen in severe heart failure, liver disease, and kidney failure. While this condition involves significant swelling, it is not typically linked to emphysema and bronchitis.
Choice D rationale
Clubbing of the nails is a common finding in chronic respiratory conditions like emphysema and bronchitis. It involves bulbous enlargement of the fingertips and nail curvature, resulting from prolonged low oxygen levels, making it a likely finding in this client.
