TEST BANK FOR WONG'S NURSING CARE OF INFANTS AND CHILDREN 11TH EDITION BY HOCKENBERRY Chapter 07: Health Promotion of the Newborn and Family MULTIPLE CHOICE 1. What is a function of brown adipose tissue (BAT) in newborns? a. Generates heat for distribution to other parts of body b. Provides ready source of calories in the newborn period c. Protects newborns from injury during the birth process d. Insulates the body against lowered environmental temperature ANS: A Brown fat is a unique source of heat for newborns. It has a larger content of mitochondrial cytochromes and a greater capacity for heat production through intensified metabolic activity than does ordinary adipose tissue. Heat generated in brown fat is distributed to other parts of the body by the blood. It is effective only in heat production. Brown fat is located in superficial areas such as between the scapulae, around the neck, in the axillae, and behind the sternum. These areas should not protect the newborn from injury during the birth process. The newborn has a thin layer of subcutaneous fat, which does not provide for conservation of heat.

Which characteristic is representative of a full-term newborns gastrointestinal tract? a. Transit time is diminished. b. Peristaltic waves are relatively slow. c. Pancreatic amylase is overproduced. d. Stomach capacity is very limited. ANS: D Newborns require frequent small feedings because their stomach capacity is very limited. A newborns colon has a relatively small volume and resulting increased bowel movements. Peristaltic waves are rapid. A deficiency of pancreatic lipase limits the absorption of fats.

Milk stool c. Meconium d. Transitional ANS: C Meconium is composed of amniotic fluid and its constituents, intestinal secretions, shed mucosal cells, and possibly blood. It is a newborns first stool. Milia involves distended sweat glands that appear as minute vesicles, primarily on the face. Milk stool usually occurs by the fourth day. The appearance varies depending on whether the newborn is breast or formula fed. Transitional stools usually appear by the third day after the beginning of feeding. They are usually greenish brown to yellowish brown, thin, and less sticky than meconium.

In term newborns, the first meconium stool should occur no later than within how many hours after birth? a. 6 b. 8 c. 12 d. 24 ANS: D The first meconium stool should occur within the first 24 hours. It may be delayed up to 7 days in very lowbirth-weight newborns. DIF: Cognitive Level: Understanding TOP: Nursing Process: Assessment MSC: Client Needs: Health Promotion and Maintenance 5. Which is true regarding an infants kidney function? a. Conservation of fluid and electrolytes occurs. b. Urine has color and odor similar to the urine of adults. c. The ability to concentrate urine is less than that of adults. d. Normally, urination does not occur until 24 hours after delivery. ANS: C At birth, all structural components are present in the renal system, but there is a functional deficiency in the kidneys ability to concentrate urine and to cope with conditions of fluid and electrolyte stress such as dehydration or a concentrated solute load. Infants urine is colorless and odorless. The first voiding usually occurs within 24 hours of delivery. Newborns void when the bladder is stretched to 15 ml, resulting in about 20 voidings per day.

Which is the nurses best interpretation of this? a. Resuscitation is likely to be needed. b. Adjustment to extrauterine life is adequate. c. Additional scoring in 5 more minutes is needed. d. Maternal sedation or analgesia contributed to the low score. ANS: B The Apgar reflects an infants status in five areas: heart rate, respiratory effort, muscle tone, reflex irritability, and color. A score of 8 to 10 indicates an absence of difficulty adjusting to extrauterine life. Scores of 0 to 3 indicate severe distress, and scores of 4 to 7 indicate moderate difficulty. All infants are rescored at 5 minutes of life, and a score of 8 is not indicative of distress; the newborn does not have a low score. The Apgar score is not used to determine the infants need for resuscitation at birth.

Which statement best represents the first stage or the first period of reactivity in the infant? a. Begins when the newborn awakes from a deep sleep b. Is an excellent time to acquaint the parents with the newborn c. Ends when the amounts of respiratory mucus have decreased d. Provides time for the mother to recover from the childbirth process
