Chapter 7: Health Promotion of the Newborn and Family - Nurselytic

Correct Answer: B

Rationale: Nasal flaring is an indication of respiratory distress. A nasal occlusion should prevent the child from breathing through the nose. Because newborns are obligatory nose breathers, this should require immediate referral. Snuffles are indicated by a thick, bloody nasal discharge without sneezing. Sneezing and thin, white mucus drainage are common in newborns and are not related to nasal flaring.

Correct Answer: C

Rationale: This is a description of the Babinski reflex. Stroking the outer sole of the foot upward from the heel across the ball of the foot causes the big toes to dorsiflex and the other toes to hyperextend. This reflex persists until approximately age 1 year or when the newborn begins to walk. The grasp reflex is elicited by touching the palms or soles at the base of the digits. The digits will flex or grasp. The Perez reflex involves stroking the newborns back when prone; the child flexes the extremities, elevating the head and pelvis. This disappears at ages 4 to 6 months. When the newborn is held so that the sole of the foot touches a hard surface, there is a reciprocal flexion and extension of the leg, simulating walking. This reflex disappears by ages 3 to 4 weeks.

Correct Answer: A

Rationale: 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.

Correct Answer: D

Rationale: 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.

Correct Answer: C

Rationale: 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.
