lack of body posturing

A newborn whose weight is above the 90th percentile on growth charts is

large-for-gestational-age.

A pregnant client is in labor. The nurse reviews a mother's prenatal history and finds that the client has diabetes mellitus. The nurse anticipates that her newborn most likely be at risk for being:

large-for-gestational-age.

A newborn is designated as extremely low birthweight. The nurse understands that this newborn's weight is:

Maternal factors that increase the chance of bearing an LGA newborn include

maternal diabetes mellitus or glucose intolerance, multiparity, prior history of a macrosomic infant, postdate gestation, maternal obesity, male fetus, and genetics

Maternal malnutrition and TORCH infection are considered

maternal factors.

Hyperextending the newborn's neck would

most likely close off the airway and is inappropriate.

bulging fontanels suggest

over hydration

A nurse is conducting a class for a group of expectant couples on fetal growth and development. The nurse determines that additional teaching is needed when the class identifies which factor as playing an important role in fetal growth and development?

paternal factors

Complications associated with a post-term newborn include

perinatal asphyxia (caused by placental aging or oligohydramnios [decreased amniotic fluid]), hypoglycemia (caused by acute episodes of hypoxia related to cord compression, which exhausts carbohydrate reserves), hypothermia (caused by loss of subcutaneous fat), and polycythemia (caused by an increased production of red blood cells to compensate for a reduced oxygen environment).

Hydration and frequent monitoring of hematocrit are important to prevent

polycythemia

Preterm newborns have

ragile blood vessels in the brain, and fluctuations in blood pressure can predispose these vessels to rupture, causing intracranial hemorrhage.

the preterm newborn is at great risk for

respiratory complications, one of which is atelectasis.

A nurse is providing care to a post-term newborn. The nurse suspects that the newborn may be developing polycythemia based on which findings? Select all that apply.

ruddy appearance seizures jaundice

Findings associated with polycythemia include

ruddy appearance (plethora), a weak sucking reflex, hypotonia, seizures, and jaundice

sudden highpitched cry; facial grimace with furrowing of brown and quivering chin; increased muscle tone; oxygen desaturation; body posturing, such as squirming, kicking, and arching; limb withdrawal and thrashing movements; increase in heart rate, blood pressure, pulse, and respirations; fussiness and irritability.

Which findings would the nurse expect in a newborn who is considered small for gestational age? Select all that apply.

sunken abdomen poor muscle tone over buttocks dry or thin umbilical cord

Interventions to reduce pain in the preterm newborn include

swaddling the newborn closely to establish physical boundaries, using gentle handling, rocking, caressing, and cuddling, encouraging kangaroo care during procedures, and offering a pacifier for nonnutritive sucking prior to a procedure. Tape should be used minimally and should be removed gently to prevent skin tearing. Environmental stimuli need to be reduced, such as by turning down the volumes on alarms. Warm rather than cool blankets facilitate relaxation. Distraction using colorful mobiles or objects also can be effective.

The nurse needs to conduct a procedure on a preterm newborn. Which measures would be most effective in reducing pain? Select all that apply.

swaddling the newborn closely offering a pacifier prior to a procedure encouraging kangaroo care during procedures

Which finding would lead the nurse to suspect that a large-for-gestational-age newborn is developing hyperbilirubinemia?

tea-colored urine

A woman gives birth to a newborn at 39 weeks' gestation. The nurse classifies this newborn as:

term.

Hyperbilirubinemia occurs with

the increased breakdown of red blood cells, but this too would not account for the wasted appearance

After 42 weeks' gestation,

the placenta loses its ability to provide adequate oxygen and nutrients to the fetus, causing the fetus to use stored nutrients to stay alive. This leads to wasting. Meconium aspiration can occur with postterm newborns, but this is not the reason for the baby's wasted appearance.

The nurse is assessing a post-term newborn. Which finding would the nurse be least likely to assess?

thick umbilical cord

Positive-pressure ventilation

used if the newborn is apneic or gasping or the pulse rate is less than 100 beats per minute.

Parents often vent their frustration and anger over the loss of their newborn on the nurse. The most appropriate reaction for the nurse is:

validate their feelings and refocus their anger.

Exposure to an intrauterine infection is unrelated to the

wasted appreance

After completing an assessment of a newborn, the nurse determines that the newborn is small-for-gestational-age based on which weight assessment?

weight of 2,400 g

A birth injury is typically characterized by

y asymmetrical movement
