Q

What is normal respiratory rate for a neonate?

A

40-60 bpm

19
Q

What is a normal blood pressure for a neonate?

A

60-90/30-60 mmHg

20
Q

What is the normal MAP for a neonate?

A

gestational age + 5

21
Q

Where should heart rate be assessed on a neonate?

A
  1. Brachial artery
  2. Femoral artery
22
Q

What considerations should you make when assessing fetal heart rate?

A
  1. Sleep vs awake
  2. Premature vs mature
23
Q

What effect should stimulation have on a neonates heart rate?

A

Should increase with stimulation

24
Q

What is the correlation between gestational age and respiratory rate?

A

Lower the gestational age, the higher the respiratory rate

25
Q

When is a neonate considered tachypneic? Bradypneic?

A

Tachy > 60
Brady < 30

26
Q

When assessing a neonates respiration, how long should you do it and why?

A

Over the course of a minute because neonates can have irregular breathing patterns

27
Q

What are the components of the respiratory assessment of a neonate?

A
  1. examination of the chest
  2. evaluation of respiratory distress
  3. auscultation of the chest
  4. chest radiograph
28
Q

What findings on a chest examination of a neonate might be indicative of respiratory complications?

A
  1. Barrel chest
  2. rib deformities
  3. absence of chest muscles
  4. pectus excavatum or carinatum
29
Q

What are the clinical sighs of respiratory distress in the neonate?

A
  1. Nasal flaring
  2. Grunting
  3. Tachypnea
  4. Retractions
30
Q

Describe the Silverman Score

A

Tool used to quantify distress and lung disease

31
Q

What are the 5 areas examined during when calculating a Silverman score?

A
  1. Upper chest
  2. Lower Chest
  3. Xiphoid retractions
  4. Nares dilation
  5. Expiratory grunting
32
Q

What score on the Silverman score is indicative of severe respiratory distress?

A

7 or greater

33
Q

Describe how a score of 0 would appear clinically

A
  1. Synchronized expansion of upper and lower chest
  2. No lower chest retractions
  3. No xiphoid retractions
  4. No nare dilations
  5. No expiratory grunting
34
Q

Describe a silverman score of 5 would appear clinically

A
  1. Lag on inspiration
  2. Retractions of lower chest just visible
  3. Xiphoid retractions just visible
  4. Minimal nasal flaring
  5. Grunting audible only to stethoscope
35
Q

Describe how a silverman score of 10 clinically presents

A
  1. Seesaw between upper and lower chest
  2. Marked lower chest retractions
  3. Marked xiphoid retractions
  4. Marked nare dilation
  5. Grunting audible without stethoscope
36
Q

What should areas of focus be when performing cardiovascular assessment on a neonate?

A
  1. Cardiac murmurs
  2. peripheral pulses
  3. capillary refill time
  4. Preductal and post-ductal oxygen saturation
37
Q

What can a heart murmur be indicative of in a new born?

A

congenital heart defects

38
Q

What method is used to assess cardiac output and peripheral circulation in a neonate

A

capillary refill

39
Q

What is a normal capillary refill in a neonate?

A

fewer than 3 seconds

40
Q

What congenital disorders are neonates mandated to be screened for at birth?

A

sickle cell anemia
cystic fibrosis
hemoglobinopathies
phenylketonuria
galactosemia

41
Q

What is the moro reflex?

A

startle reflex
infant is startled, arms extend and abduct outward with palms open which is quickly followed by bringing arms inward with hands clenched

42
Q

What is the grasp reflex?

A

neonates hand closes around the finger and grasp tightens when the finger is moved within the palm

43
Q

What is the rooting reflex?

A

neonate turns head toward the stroked cheek side and begins making sucking motions
