Q

What does REEDA stand for?

A

Redness, ecchymosis, edema, discharge and approximation of perineum

22
Q

A life-threatening lung disorder that results from underdeveloped and small alveoli and insufficient levels of pulmonary surfactant

A

Respiratory Distress syndrome

22
Q

What two combined factors can cause an alteration in alveoli surface tension that eventually results in atelectasis.

A

underdeveloped and small alveoli and insufficient levels of pulmonary surfactant

22
Q

The effects of atelectasis are:

A

■ Hypoxemia and hypercarbia
■ Pulmonary artery vasoconstriction
■ Right-to-left shunting through the ductus arteriosus and foramen ovale as the neonate’s body attempts to counteract the compromised pulmonary perfusion
■ Metabolic acidosis that occurs from a buildup of lactic acid that results from prolonged periods of hypoxemia
■ Respiratory acidosis that occurs from the collapsed alveoli being unable to expel excess carbon dioxide

22
Q

RDS affects ___% of all premature infants, the majority of these born at less than ___ weeks’ gestation

A

10%, 28

22
Q

What is pulmonary surfactant made of?

A

Pulmonary surfactant is a substance that is composed of 90% phospholipids and 10% proteins.

22
Q

■ Pulmonary surfactant is produced by _____ ___ ___ within the lungs.
■ The alveolar cells begin to produce _____
around _____ weeks and continue to term.
■ It reduces the ______ within the lungs and increases the ______ which prevents the alveoli from collapsing at the end of _____.

A

type II, alveolar cells
pulmonary surfactant, 24–28
surface tension, pulmonary compliance, expiration

23
Q

Tests used to evaluate fetal lung maturity are:

A

Phosphatidylglycerol (PG), Lecithin/sphingomyelin (L/S) ratio

23
Q

Where is PG synthesized, present in, and decrease the risk of what?

A

■ PG is synthesized from mature lung alveolar cells.
■ It is present in the amniotic fluid within 2–6 weeks of
full-term gestation.
■ The presence of PG indicates lung maturity and a decrease indicates risk of respiratory distress syndrome.

23
Q

Lecithin/sphingomyelin (L/S) is detected where, and why is the ratio important?

A

■ Lecithin and sphingomyelin are two phospholipids that are
detected in the amniotic fluid.
■ The ratio between the two phospholipids provides information on the level of surfactant.

23
Q

A L/S ratio in non diabetics vs diabetics

A

■ A L/S ratio greater than 2:1 in a nondiabetic woman
indicates the fetus’s lungs are mature.
■ A L/S ratio of 3:1 in a diabetic woman indicates the
fetus’s lungs are mature.
