Wong s Essentials of Pediatric Nursing 10th Edition by Hockenberry Rodgers Wilson (chapter 9) questions and answers Chapter 09: Health Promotion of the Infant and Family Hockenberry: Wong’s Essentials of Pediatric Nursing, 10th Edition MULTIPLE CHOICE 1. A nurse is assessing a 12-month-old infant. Which statement best describes the infant’s physical development a nurse should expect to find? a. Anterior fontanel closes by age 6 to 10 months. b. Binocularity is well established by age 8 months. c. Birth weight doubles by age 5 months and triples by age 1 year. d. Maternal iron stores persist during the first 12 months of life. ANS: C Growth is very rapid during the first year of life. The birth weight has approximately doubled by age 5 to 6 months and triples by age 1 year. The anterior fontanel closes at age 12 to 18 months. Binocularity is not established until age 15 months. Maternal iron stores are usually depleted by age 6 months.

The nurse is assessing a 6-month-old healthy infant who weighed 7 pounds at birth. The nurse should expect the infant to now weigh approximately how many pounds? a. 10 b. 15 c. 20 d. 25 ANS: B Birth weight doubles at about age 5 to 6 months. At 6 months, a child who weighed 7 pounds at birth would weigh approximately 15 pounds; 10 pounds is too little. The infant would have gone from the 50th percentile at birth to below the 5th percentile; 20 to 25 pounds is too much. The infant would have tripled the birth weight at 6 months.

The nurse is doing a routine assessment on a 14-month-old infant and notes that the anterior fontanel is closed. How should the nurse interpret this finding? a. Normal finding b. Finding requiring a referral c. Abnormal finding d. Normal finding, but requires rechecking in 1 month ANS: A This is a normal finding. The anterior fontanel closes between ages 12 and 18 months. No further intervention is required. DIF: Cognitive Level: Apply REF: p. 301 TOP: Integrated Process: Nursing Process: Assessment MSC: Area of Client Needs: Health Promotion and Maintenance 4. A nurse is assessing a 6-month-old infant. The nurse recognizes the posterior fontanel usually closes at which age? a. 6 to 8 weeks b. 10 to 12 weeks c. 4 to 6 months d. 8 to 10 months ANS: A The bones surrounding the posterior fontanel fuse and close by age 6 to 8 weeks; 10 to 12 weeks, 4 to 6 months, and 8 to 10 months are too late. The posterior fontanel is usually closed by age 8 weeks.

The parents of a 9-month-old infant tell the nurse that they have noticed foods such as peas and corn are not completely digested and can be seen in their infant’s stools. The nurse’s explanation of this is based on which statement? a. Child should not be given fibrous foods until digestive tract matures at age 4 years. b. Child should not be given any solid foods until this digestive problem is resolved. c. This is abnormal and requires further investigation. d. This is normal because of the immaturity of digestive processes at this age. ANS: D The immaturity of the digestive tract is evident in the appearance of the stools. Solid foods are passed incompletely broken down in the feces. An excess quantity of fiber predisposes the child to large, bulky stools. This is normal for the child and is a normal part of the maturational process; no further investigation is necessary.

A 3-month-old infant, born at 38 weeks of gestation, will hold a rattle if it is put in her hands, but she will not voluntarily grasp it. How should the nurse interpret this action? a. Normal development b. Significant developmental lag c. Slightly delayed development due to prematurity d. Suggestive of a neurologic disorder such as cerebral palsy ANS: A Holding a rattle but not voluntarily grasping it is indicative of normal development. Reflexive grasping occurs during the first 2 to 3 months and then gradually becomes voluntary. The infant is expected to be able to perform this task by age 3 months. If the child’s age is corrected because of being 2 weeks preterm, the child is at the midpoint of the range for this developmental task and the behavior is age appropriate. No evidence of neurologic dysfunction is present
