A 10-month-old infant demonstrates object permanence by actively searching for a toy hidden under a blanket. Which nursing action best supports the infant's cognitive development at this stage?
Limit the infant's exposure to new toys to avoid overstimulation and confusion,
Encourage parents to play peek-a-boo and other interactive games that reinforce object permanence.
Discourage exploratory behaviors such as putting objects in the mouth to prevent choking hazards.
Focus solely on physical milestones such as crawling and walking, as cognitive development is less critical at this age.
The Correct Answer is B
A. Limit the infant's exposure to new toys to avoid overstimulation and confusion is incorrect because exposure to a variety of age-appropriate toys promotes cognitive development. Limiting interaction with toys may hinder problem-solving skills and learning about object permanence.
B. Encourage parents to play peek-a-boo and other interactive games that reinforce object permanence is correct because interactive games like peek-a-boo help infants understand that objects exist even when out of sight, directly supporting the development of object permanence. These activities also enhance social interaction, attention span, and memory, which are critical at this developmental stage.
C. Discourage exploratory behaviors such as putting objects in the mouth to prevent choking hazards is incorrect because exploratory behaviors, including mouthing objects, are a normal and important part of sensory and cognitive development in infants. While safety precautions are necessary, discouraging exploration can limit learning opportunities.
D. Focus solely on physical milestones such as crawling and walking, as cognitive development is less critical at this age is incorrect because cognitive development is highly active during infancy. Milestones like object permanence, problem-solving, and early language acquisition are equally important to track and support alongside physical growth.

Correct Answer is C
Explanation
A. This is incorrect because Rho(D) immune globulin is not given only after delivery. It is routinely administered during pregnancy to prevent Rh sensitization that can occur from fetal–maternal blood mixing before birth.
B. This is incorrect because Rho(D) immune globulin is not given monthly. Routine administration occurs once at approximately 28 weeks of gestation and again postpartum if the newborn is Rh-positive.
C. This is correct because an Rh-negative, unsensitized pregnant woman should receive Rho(D) immune globulin at 28 weeks of gestation and within 72 hours after delivery if the infant is Rh-positive. This prevents the mother from forming antibodies against Rh-positive red blood cells.
D. This is incorrect because Rho(D) immune globulin is needed during the first pregnancy and any subsequent pregnancies if the mother is Rh-negative and unsensitized. Sensitization can occur during any pregnancy, not just after the second.
Correct Answer is A
Explanation
A. "Your baby should weigh about 15 lbs by now" is correct. When discussing infant growth, nurses refer to standard pediatric growth milestones, which indicate that a healthy, full-term infant typically doubles their birth weight by 4–6 months and triples it by 12 months. Since this infant weighed 7 lbs at birth, the expected weight at 6 months would be approximately 14 lbs, making “about 15 lbs” an accurate and reassuring estimate. This reflects adequate nutrition and normal metabolic development.
B. "Your baby should weigh about 25 lbs by now" is incorrect because this weight is significantly above the expected range for a 6-month-old. A 25-lb infant at this age would be unusual and could suggest measurement error or a rare growth disorder.
C. "Your baby should weigh about 20 lbs by now" is incorrect because 20 lbs corresponds to an older infant, likely 12–15 months old, and is too high for a 6-month-old who weighed 7 lbs at birth.
D. "Your baby should weigh about 10 lbs by now" is incorrect because 10 lbs is less than double the birth weight. If a 6-month-old weighed only 10 lbs, it could indicate growth delay, malnutrition, or other underlying health concerns, requiring further assessment.
