NRP

Question 1

What is the normal physiological progression of FRC, compliance and resistance over the first 24 HOL in a 28 weeker?

Answer 1

Increasing FRC
Decreasing Resistance
Increasing Lung Compliance

Question 2

How does fetal temp differ from maternal temp?

Answer 2

Fetal temp is 0.9’ F (0.5´ C) above maternal temps

Question 3

How to detect mask / ETT leak on ventilator wave form?

Answer 3

Minimal leak
Flow returns to 0 and insp volumes = exp volumes

Large leak
Flow does NOT return to 0 and insp volume > exp volume

Question 4

How to detect long itime on ventilator flow wave form?

Answer 4

Lack of flow at the end of inspiratory flow

Question 5

Most effective step in neonatal resuscitation?

Answer 5

Establishing adequate ventilation

Question 6

MOA of brown fat with hypothermia

Answer 6

Brown fat releases NE —> systemic + pulmonary vasoconstriction —> decreased tissue oxygenation

Question 7

What initiates secondary energy failure in HIE?

Answer 7

Cell membrane fxn fails —> increase EAA (glutamate) —-> over activation of neuronal receptors (NMDA) —> increase Calcium —-> increase lipase / protease/ phospholipase/ endonuclease

Question 8

The most reliable method for determining the effectiveness of CPR in adults?

Answer 8

Diastolic blood pressure
Coronary perfusion pressure (difference between aortic BP
and RA BP).

Question 9

What is the formula for length of ETT placement ?

Answer 9

6 + (baby’s weight in kg) = taping at lip
