Chapter 10: Health Promotion of the Infant and Family Chapter 10: Health Promotion of the Infant and Family 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. The nurse should interpret this as a(n): 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.

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. The nurse should interpret this as: 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.

In terms of fine motor development, what should the infant of 7 months be able to do? a. Transfer objects from one hand to the other and bang cubes on a table. b. Use thumb and index finger in crude pincer grasp and release an object at will. c. Hold a crayon between the fingers and make a mark on paper. d. Release cubes into a cup and build a tower of two blocks. ANS: A By age 7 months, infants can transfer objects from one hand to the other, crossing the midline, and bang objects on a hard surface. The crude pincer grasp is apparent at about age 9 months, and releasing an object at will is seen around 8 months. The child can scribble spontaneously at age 15 months. At age 12 months, the child can release cubes into a cup and build a small tower.

At what age can most infants sit steadily unsupported? a. 4 months b. 6 months c. 8 months d. 10 months ANS: C Sitting erect without support is a developmental milestone usually achieved by 8 months. At age 4 months, an infant can sit with support. At age 6 months, the infant will maintain a sitting position if propped. By 10 months, the infant can maneuver from a prone to a sitting position.

The parents of a 3-month-old infant report that their infant sleeps supine (face up) but is often prone (face down) while awake. The nurse’s response should be based on knowledge that this is: a. unacceptable because of the risk of sudden infant death syndrome (SIDS). b. unacceptable because it does not encourage achievement of developmental milestones. c. acceptable to encourage fine motor development. d. acceptable to encourage head control and turning over. ANS: D These parents are implementing the guidelines to reduce the risk of SIDS. Infants should sleep on their backs and then be placed on their abdomens when awake to enhance development of milestones such as head control. The face-down position while awake and on the back for sleep are acceptable because they reduce risk of SIDS and allow achievement of developmental milestones. These position changes encourage gross motor, not fine motor, development.

By which age should the nurse expect an infant to be able to pull to a standing position? a. 6 months b. 8 months c. 11 to 12 months d. 14 to 15 months ANS: C Most infants can pull themselves to a standing position at age 9 months. Infants who are not able to pull themselves to standing by age 11 to 12 months should be further evaluated for developmental dysplasia of the hip. At 6 months, infants have just obtained coordination of arms and legs. By age 8 months, infants can bear full weight on their legs. Any infant who cannot pull to a standing position by age 1 year should be referred for further evaluation.
