The school nurse is conducting vision screening for a 7-year-old girl and documents the condition "amblyopia." What would the nurse tell the parents about this condition?
"Amblyopia is reduced vision in an eye that has not been adequately used during early development."
"Amblyopia is a malalignment of the eye, which occurs at birth."
"Amblyopia is an uncorrected refractive error of the eye."
"Amblyopia is a clouding of the lens of the eye caused by trauma to the eye."
The Correct Answer is A
A. Amblyopia, often referred to as "lazy eye," is reduced vision in one eye due to abnormal visual development during early childhood.
B. Malalignment of the eyes typically refers to strabismus, not amblyopia.
C. Refractive errors such as myopia or hyperopia can cause visual impairment but are not specifically related to amblyopia.
D. Clouding of the lens of the eye is more commonly associated with conditions like cataracts, not amblyopia.

Correct Answer is D
Explanation
A. Conduction heat loss typically occurs through direct contact with a cooler surface, but in this scenario, the baby is under a radiant warmer, reducing the likelihood of conduction heat loss.
B. Axillary temperatures are generally accurate for newborns when measured properly.
C. A normal temperature for a neonate is between 97 and 99 degrees F (36 to 37 degrees C).
D. Brown adipose tissue is a specialized type of fat that generates heat by metabolizing fatty acids. It is abundant in full-term neonates, but scarce in preterm neonates, especially those born before 34 weeks' gestation. Therefore, preterm neonates have less ability to maintain their body temperature and are prone to hypothermia.
Correct Answer is A
Explanation
A. At 9 months of age, babies are able to crawl and explore their environment. They may pick up and put anything in their mouth, which can cause choking or poisoning. Therefore, the nurse should warn the mother about keeping the floor clear of small objects, such as coins, buttons, beads, or toys with detachable parts.
B. Safety procedures during baths are crucial, but this topic may have been covered in earlier visits or could be discussed alongside creating a toddler-safe home.
C. This more relevant for older babies or toddlers who can stand, walk, or climb.
D. Cautioning about putting the baby in a walker is important, but it may not be the most immediate concern at 9 months, as many babies start using walkers around 6-9 months. Creating a safe home environment encompasses a broader range of potential hazards.
