Deck 4: Exam and Assessment of the Neonatal and Pediatric Patient

Question 1

What measures can the therapist take to prevent heat loss and cold stress before performing resuscitation on a preterm neonate?
I)Dry the infant's skin.
II)Wrap the infant in pre-warmed blankets.
III)Remove wet linens from around the infant.
IV)Measure the neonate's body temperature.

A)IV only
B)I and II only
C)I,II,and III only
D)I,II,and IV only

Answer 1

C
Preventing heat loss is critical when caring for a newborn because cold stress increases oxygen consumption and impedes effective resuscitation.If possible,deliver the infant in a warm,draft-free area.Heat loss can be greatly reduced by rapidly drying the infant's skin,immediately removing wet linens,and wrapping the infant in pre-warmed blankets.

Question 2

Which of the following factors are taken into consideration when assessing the gestational age of a neonate?
I)Previous maternal pregnancies
II)Prenatal ultrasound evaluations
III)Postnatal findings based on physical and neurologic examinations
IV)Gestational duration based on the last menstrual cycle

A)I and III only
B)I,II,and III only
C)I,II,and IV only
D)II,III,and IV only

Answer 2

D
Ideally,gestational age assessment is performed before the neonate is 12 hours old to allow the greatest reliability for infants less than 26 weeks of gestational age.Evaluating gestational age requires consideration of several factors.The three main factors are as follows:
•Gestational duration based on the last menstrual cycle
•Prenatal ultrasound evaluation
•Postnatal findings based on physical and neurologic examinations

Question 3

As the head of a neonate contaminated with meconium emerges at birth,the heart rate monitor indicates 120 beats/minute,and the physician notices that the infant has good muscle tone and a strong respiratory effort.What should the physician do at this time to provide airway care?

A)Intubate the infant immediately.
B)Perform pharyngeal and tracheal suctioning immediately.
C)Perform tracheal suctioning only at this time.
D)Only routine monitoring of respiratory vital signs is needed at this time.

Answer 3

D
Attempts to suction meconium from the pharynx or trachea before birth,during birth,or postpartum increase the likelihood of severe aspiration pneumonia.Some obstetricians perform oral and nasal suctioning on meconium-stained infants after delivery of the head but before delivery of the shoulders.However,a large,multicenter,randomized trial showed no benefit from this practice.Therefore,current recommendations for infants with meconium are that (1)no intrapartum suctioning should occur(2)infants who are vigorous at birth (strong respiratory effort,a heart rate of greater than 100 beats/min,good muscle tone)should not receive tracheal suctioning;and (3)infants who are not vigorous (no or poor respiratory effort,a heart rate of less than 100 beats/min,poor muscle tone)may receive direct laryngotracheal suctioning.

Question 4

What condition would be responsible for the therapist observing a pulse oximeter indicating decreased perfusion while central blood pressure remains normal?

A)Volume depletion with compensatory peripheral vasoconstriction
B)Hypoplastic left-sided heart syndrome
C)Hypervolemia with compensatory peripheral vasodilation

A)I only
B)II only
C)I,III,and IV only
D)II,III,and IV only

Question 6

Why are chest retractions more prominent among neonates than among older children and adults?

A)Because neonates generate a greater subatmospheric intrapleural pressure
B)Because newborns have relatively thin and weak musculature and a less rigid thorax
C)Because neonates have a much higher respiratory rate
D)Because airway resistance through the smaller caliber airways is higher

Question 7
