NR 509 FINAL EXAMS (50 Q & A with Explanation)
Question:
Ophthalmoscopic examination of the retina reveals a normal arteriovenous crossing. This
appears as if the:
vein tapers down on either side of the artery.vein is twisted on the distal side of the artery.vein
crosses beneath the artery. Correctvein stops abruptly on either side of the artery.
Explanation:
In the normal eye, the vein appears to cross beneath the artery. When the arterial walls lose
their transparency, changes appear in the arteriovenous crossings. Decreased transparency of
the retina probably contributes to AV nicking and AV tapering. In AV nicking, the vein appears to
stop abruptly on either side of the artery. In tapering, the vein appears to taper down either side
of the artery. With banking, the vein appears to be twisted on the distal side of the artery and
forms a dark wide knuckle appearance.
Question:
Otosclerosis is an example of a(n):
conductive hearing loss. Correctsensorineural hearing loss.mixed hearing loss.acquired
hearing loss.
Explanation:
Otosclerosis is a hereditary disorder of the labyrinthine capsule in which abnormal bone growth
occurs around the ossicles resulting in fixation of the stapes. The stapes does not vibrate which
reduces sound transmission to the inner ear. This produces a conductive hearing loss.
Question:
Which of the following findings in a preschooler would indicate the need for further evaluation?
Intelligible speech by 24 months of ageVariation in quality of speech pattern and toneResponds
to facial expressions and gestures rather than to verbal explanations CorrectLooks at people
when they speak
