Question

question 61
pectus excavatum is more commonly referred to as:
○ cervical ribs
○ pigeon or bird breast
○ sunken chest
○ sway back

question 62
the eye structure that lies directly behind the pupil and iris is the:
○ vitreous fluid
○ retina
○ lens
○ cornea

question 63
the diagnostic term cataract actually means:
○ impaired vision as a result of aging
○ separation of the retina from the choroid layer
○ abnormally increased intra - ocular pressure
○ clouding of the lens of the eye

Explanation:

• Question 61: Pectus excavatum is a congenital chest wall deformity where the sternum and ribs grow abnormally, causing the chest to sink inwards, hence the common name "sunken chest". Cervical ribs are extra ribs near the neck. Pigeon or bird breast (pectus carinatum) is a different chest deformity where the chest protrudes. Sway back refers to a posture problem of the spine.
• Question 62: The lens is located directly behind the pupil and iris. The vitreous fluid is in the back of the eye. The retina is the light - sensitive layer at the back. The cornea is the clear front part of the eye.
• Question 63: A cataract is the clouding of the lens of the eye. Impaired vision due to aging can be presbyopia. Separation of the retina from the choroid is retinal detachment. Abnormally increased intra - ocular pressure is glaucoma.

Answer:

• Question 61: sunken chest
• Question 62: lens
• Question 63: clouding of the lens of the eye
