Complete question:

The student nurse compares the major developmental characteristics of vision in 12-week-old infants with those at 28 weeks old. Which statement demonstrates correct knowledge regarding the developmental milestones?

a) The infant can recognize the feeding bottle at 12 weeks and can follow rapidly moving objects by 28 weeks

b) The infant develops functional tear glands for the first time at 12 weeks and starts to accommodate to near objects at 28 weeks

c) The infant can adjust posture to see an object at 12 weeks and develops a binocular vision for the first time around 28 weeks

d) The infant is able to fixate on a 1.25 cm(0.5-inch) block at 12 weeks and is able to discriminate between simple geometric forms by 28 weeks.

d) The infant is able to fixate on a 1.25 cm(0.5 Inch) block at 12 weeks

and is able to discriminate between simple geometric forms by 28 weeks

Explanation:

• In the the first option, it is true the infant can recognize the bottle at 12 weeks, but the infant would not be able to follow rapidly moving objects at 28 weeks. The least age an infant can be able to follow such objects is at 44 weeks. Hence, this statement is not suitable.

• It takes just 4 weeks for an infant to develop the first functional tear gland and not the stipulated 12 weeks in this question. Also, the infant starts to accommodate near objects between 12 and 20 weeks and not at 28 weeks. This option is not correct

• An infant can't start adjusting posture as early as 12 weeks. For aninfant to adjust posture to see an object, the infant must be at least 20 weeks old. Binocular vision can be developed as early as 12 weeks. This option is wrong

• An infant can be able to fixate on a block at 12 weeks and an infant will also be able to discriminate between simple geometric forms at by 28 weeks. Infants can't see as clear as older humans because they are still trying to develop a proper visual system. When the student nurse makes this statement in option d, we can say the student nurse now has the correct knowledge regarding the developmental characteristics of vision in infants.
