during inspiration

Question 16

What is Hoover’s sign?

Answer 16

Paradoxical (seesaw) breathing in. The abdomen moves outward while chest moves inward during inpiration.

Question 17

Hoover sign is an indication for what?

Answer 17

Airway obstruction or lower respiratory tract disease in infants

Question 18

What are the 5 components of APGAR score?

Answer 18

A- Appearance (Color)

P - Pulse (Heart Rate)

G - Grimace (Reflrex irritability)

A - Activity (Muscle tone)

R - Respiratory rate

Question 19

This is a subjective qualitative evaluation done at 1 and 5 minutes to determine “survivability” of the newborn.

Answer 19

Apgar Score

Question 20

A newborn was crying loudly and in active motion, has a heart rate of 102bpm, and has acrocyanosis. What is the APGAR score for this newborn? Interpret score.

Answer 20

Apgar score: 9 (1+2+2+2+2)

Normal

Question 21

Why is thermoregulation very important in newborns?

Answer 21

Variation in respiratory rate occurs if room temperature is very warm or cool: Most often tachypnea, sometimes bradypnea

Question 22

Other causes of depressed respiration in the newborn

Answer 22

Maternal environment during labor (sedatives, compromised blood supply to the child

Mechanical Obstruction by mucus

Neurological damage (birth trauma: injury to C3,C4, C5)

Question 23

True or False: Premature infants are more likely to have irregular respiratory patterns

Answer 23

True

Question 24

Sequence of relatively vigorous respiratory efforts followed by apnea of as long as 10-15 seconds

Answer 24

Periodic breathing

Question 25

Criteria for Apnea of prematurity

Answer 25

Cessation of breathing is ≥20 seconds Accompanied by braycardia Centrally cyanotic (check oral cavity)

Question 26

What are the normal breath sounds?

Answer 26

Tracheobronchial = tubular sound; air being blown through a tube Vesicular = soft and low pitched; sound of wind blowing through trees, causing the leaves to rustle

Question 27

True or False: Bronchial breath sounds heard at the bases of the lungs is normal.

Answer 27

False. Abnormal

Question 28

What are the adventitious breath sounds?

Answer 28

Crackles = cracking or bubbling sonds Ronchi = reflect obstruction of larger airways with mucus or secretions; "halak" or harsh breath sounds Wheeze = whistling soudn; reflect narrowing of smaller airways or bronchioles; Expiratory Stridor = upper airway obstruction; inspiratory; high pitched, piercing sound Grunting = Expiration; partially closed vocal cords; sign of severe respiratory distress

Question 29

True or False. Infant's chest is normally hyperressonant throughout

Answer 29

True. Dullness = Consolidation (pneumoniar)/ mass

Question 30

This is due to lack of surfactant resulting to alveolar collapse and reduce distensibility of the lungs

Answer 30

Hyaline Membrane Disease or Respiratory Distress Syndrome

Question 31

Floppiness of the trachea Generally bening and self-limiting with age. PE findings: Wheezing and inspiratory stridor

Answer 31

Tracheomalacia

Question 32

Caused by parainfluenza virus which causes inflammation of subglottic area PE findings: Harsh stridorous cough "bark of a seal"; labored breathing; retraction; inpiratory stridor; does not always present with fever
