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
The Angle of Louis, also known as the sternal angle, is located at the level of the 2nd intercostal space. It is a significant landmark in clinical examinations because it is used to locate important areas of the chest, such as the aortic and pulmonic areas, for auscultation.
Choice B rationale
The 3rd intercostal space is not the correct location for the Angle of Louis. The sternal angle is found at the level of the 2nd intercostal space, not the 3rd. Therefore, this option is incorrect.
Choice C rationale
The 2nd rib attaches at the level of the Angle of Louis. The sternal angle is an anatomical landmark where the manubrium and the body of the sternum meet, and it corresponds with the attachment of the 2nd rib.
Choice D rationale
The 4th intercostal space is not the correct location for the Angle of Louis. The sternal angle is located at the 2nd intercostal space, not the 4th. Therefore, this option is incorrect. .
