1. At what age is binocularity, the ability to fixate on one visual field with both eyes simultaneously, typically achieved?

Correct answer: B

Rationale: Binocularity, the ability to fixate on one visual field with both eyes simultaneously, is typically achieved by the age of 3 to 4 months. Achieving binocularity at 1 month is too early for most infants as their visual system is still developing. Similarly, 6 to 8 months and 12 months are beyond the normal age range for achieving binocularity, and delayed achievement could indicate potential issues like strabismus, which may lead to visual impairment if not addressed.

2. Which explains the importance of detecting strabismus in young children?

Correct answer: B

Rationale: Undetected strabismus can lead to amblyopia, where the brain favors one eye over the other, potentially resulting in permanent vision loss in the affected eye.

3. The nurse is teaching parents about expected language development for their 6-month-old infant. The nurse recognizes the parents understand the teaching if they make which statement?

Correct answer: D

Rationale: At 6 months, infants typically begin to combine syllables like "dada" or "mama," but they do not yet understand the meaning of these words.

4. Which of the following is a key feature of autism spectrum disorder?

Correct answer: A

Rationale: Delayed speech development is a significant feature of autism spectrum disorder. Many children with autism exhibit delays in speech and language development, which can be one of the early signs of the condition. Hyperactivity, lack of interest in toys, and aggressive behavior are not key defining features of autism spectrum disorder. While some individuals with autism may exhibit these behaviors, they are not universally characteristic of the disorder.

5. The nurse is seeing an adolescent and the parents in the clinic for the first time. Which should the nurse do first?

Correct answer: A

Rationale: Introducing oneself is the first step in establishing a rapport and setting a professional tone for the interaction.
