Respiratory Distress Syndrome (MIDTERM)

Question 1

Other Term for RDS

Answer 1

Hyaline Membrane Distress

Question 2

When do Hyaline Membrane Distress mostly occur?

Answer 2

Preterm infants; Diabetic mothers; Cesarean Birth; Decreased blood perfusion of the lungs

Question 3

What hours do RDS worsen?

Answer 3

48 to 72 hours of life

Question 4

How many % will survive RDS?

Answer 4

90%

Question 5

True or False: The more premature the baby the more severity of RDS.

Answer 5

TRUE

Question 6

Pathologic feature of RDS.

Answer 6

Hyalin (fibrous) membrane formed an exudate on the infants blood that begins to line the: TERMINAL BRONCHIOLES, ALVEOLAR DUCTS, AND ALVEOLI

Question 7

Where do gas exchange happen?

Answer 7

Lungs

Question 8

How many lobes does the lungs have?

Answer 8

5 lobes

Question 9

How many lobes do our left lung have?

Answer 9

2 lobes (upper and lower)

Question 10

How many lobes do our right lung have?

Answer 10

3 lobes (upper, lower, and middle)

Question 11

It prevents the exchange of oxygen and carbon dioxide at the alveolar-capillary membrane that interferes with effective oxygenation which causes low or absence of the surfactant.

Answer 11

Hyaline Membrane

Question 12

The phospholipid that normally lines the alveoli and reduces surface tension to keep alveoli from collapsing on expiration.

Answer 12

Surfactant

Question 13

The surfactant is composed of?

Answer 13

70% lipids and 30% protein

Question 14

How many AOG till surfactant produces?

Answer 14

24 to 28 weeks of pregnancy

Question 15

AOG till surfactant will be present in the amniotic fluid.

Answer 15

28 to 32 weeks

Question 16

when to surfactant will be fully developed

Answer 16

35th week of AOG

Question 17

During the lack of surfactant subtle signs may appear such as:

Answer 17

Low body temperature
Sternal and costal retractions
Tachypnea
Nasal tachypnea
Cyanotic mucous membrane

Question 18

Due to lack of surfactant, closure of glottis causes

Answer 18

Expiratory grunting

Question 19

As RDS increases, infant may exhibit

Answer 19

Seesaw respiration
Heart failure
Pale gray skin
periods of apnea
Bradycardia
Pneumothorax

Question 20

Seesaw respiration during inspiration

Answer 20

Anterior chest retracts and abdomen protrudes

Question 21

Seesaw respiration during expiration

Answer 21

Sternum rises

Question 22

Evidence of heart failure

Answer 22

Low urine output and Edema of extremities

Question 23

Therapeutic management for RDS

Answer 23

surfactant replacement
oxygen administration
keep infant warm

Question 24

Surfactant replacement to restore naturally occurring lung surfactant to improve lung compliance

Answer 24

SURVANTA

Question 25

It reduces infant's metabolic oxygen demand

Answer 25

Keeping warm

Question 26

Can help prevent preterm birth

Answer 26

Magnesium Sulfate

Question 27

Steroids appear to quicken the formation of lecithin (24-34 weeks)

Answer 27

Betamethasone

Question 28

Correct metabolic acidosis

Answer 28

Sodium Bicarbonate (IV)
